You can download the latest sample APK from this repo here: https://github.com/afollestad/material-dialogs/blob/master/sample/sample.apk
It's also on Google Play:
Having the sample project installed is a good way to be notified of new releases. Although Watching this repository will allow GitHub to email you whenever I publish a release.
The Gradle dependency is available via jCenter. jCenter is the default Maven repository used by Android Studio.
The minimum API level supported by this library is API 14.
The core module contains all the major classes of this library, including MaterialDialog.
You can create basic, list, single/multi choice, progress, input, etc. dialogs with core.
dependencies {
// ... other dependencies here
implementation 'com.afollestad.material-dialogs:core:0.9.6.0'
}The commons module contains extensions to the library that not everyone may need. This includes the
ColorChooserDialog, FolderChooserDialog, the Material Preference classes, and MaterialSimpleListAdapter/MaterialSimpleListItem.
dependencies {
// ... other dependencies here
implementation 'com.afollestad.material-dialogs:commons:0.9.6.0'
}It's likely that new extensions will be added to commons later.
See the project's Releases page for a list of versions with their changelogs.
If you Watch this repository, GitHub will send you an email every time I publish an update.
First of all, note that MaterialDialog extends DialogBase, which extends android.app.Dialog.
Here's a basic example that mimics the dialog you see on Google's Material design guidelines
(here: http://www.google.com/design/spec/components/dialogs.html#dialogs-usage). Note that you can
always substitute literal strings and string resources for methods that take strings, the same goes
for color resources (e.g. titleColor and titleColorRes).
new MaterialDialog.Builder(this)
.title(R.string.title)
.content(R.string.content)
.positiveText(R.string.agree)
.negativeText(R.string.disagree)
.show();Your Activities need to inherit the AppCompat themes in order to work correctly with this library.
The Material dialog will automatically match the positiveColor (which is used on the positive action
button) to the colorAccent attribute of your styles.xml theme.
If the content is long enough, it will become scrollable and a divider will be displayed above the action buttons.
I've had lots of issues asking how you dismiss a dialog. It works the same way that AlertDialog does, as
both AlertDialog and MaterialDialog are an instance of android.app.Dialog (which is where dismiss()
and show() come from). You cannot dismiss a dialog using it's Builder. You can only dismiss a
dialog using the dialog itself.
There's many ways you can get an instance of MaterialDialog. The two major ways are through the show() and build()
methods of MaterialDialog.Builder.
Through show(), which immediately shows the dialog and returns the visible dialog:
MaterialDialog dialog = new MaterialDialog.Builder(this)
.title(R.string.title)
.content(R.string.content)
.positiveText(R.string.agree)
.show();Through build(), which only builds the dialog but doesn't show it until you say so:
MaterialDialog.Builder builder = new MaterialDialog.Builder(this)
.title(R.string.title)
.content(R.string.content)
.positiveText(R.string.agree);
MaterialDialog dialog = builder.build();
dialog.show();Once the dialog is shown, you can dismiss it:
dialog.dismiss();There are other various places where the MaterialDialog instance is given, such as in some callbacks
that are discussed in future sections below.
MaterialDialog supports the display of an icon just like the stock AlertDialog; it will go to the left of the title.
new MaterialDialog.Builder(this)
.title(R.string.title)
.content(R.string.content)
.positiveText(R.string.agree)
.icon(R.drawable.icon)
.show();You can limit the maximum size of the icon using the limitIconToDefaultSize(), maxIconSize(int size),
or maxIconSizeRes(int sizeRes) Builder methods.
If you have multiple action buttons that together are too wide to fit on one line, the dialog will stack the buttons to be vertically oriented.
new MaterialDialog.Builder(this)
.title(R.string.title)
.content(R.string.content)
.positiveText(R.string.longer_positive)
.negativeText(R.string.negative)
.show();You can set stacking behavior from the Builder:
new MaterialDialog.Builder(this)
...
.stackingBehavior(StackingBehavior.ADAPTIVE) // the default value
.show();You can specify neutral text in addition to the positive and negative text. It will show the neutral action on the far left.
new MaterialDialog.Builder(this)
.title(R.string.title)
.content(R.string.content)
.positiveText(R.string.agree)
.negativeText(R.string.disagree)
.neutralText(R.string.more_info)
.show();As of version 0.8.2.0, the callback() Builder method is deprecated in favor of the individual callback methods
discussed below. Earlier versions will still require use of ButtonCallback.
To know when the user selects an action button, you set callbacks:
new MaterialDialog.Builder(this)
.onPositive(new MaterialDialog.SingleButtonCallback() {
@Override
public void onClick(MaterialDialog dialog, DialogAction which) {
// TODO
}
})
.onNeutral(new MaterialDialog.SingleButtonCallback() {
@Override
public void onClick(MaterialDialog dialog, DialogAction which) {
// TODO
}
})
.onNegative(new MaterialDialog.SingleButtonCallback() {
@Override
public void onClick(MaterialDialog dialog, DialogAction which) {
// TODO
}
})
.onAny(new MaterialDialog.SingleButtonCallback() {
@Override
public void onClick(MaterialDialog dialog, DialogAction which) {
// TODO
}
});If you are listening for all three action buttons, you could just use onAny(). The which (DialogAction)
parameter will tell you which button was pressed.
If autoDismiss is turned off, then you must manually dismiss the dialog in these callbacks. Auto dismiss is on by default.
Checkbox prompts allow you to display a UI similar to what Android uses to ask for a permission on API 23+.
Note: you can use checkbox prompts with list dialogs and input dialogs, too.
new MaterialDialog.Builder(this)
.iconRes(R.drawable.ic_launcher)
.limitIconToDefaultSize()
.title(R.string.example_title)
.positiveText(R.string.allow)
.negativeText(R.string.deny)
.onAny(new MaterialDialog.SingleButtonCallback() {
@Override
public void onClick(MaterialDialog dialog, DialogAction which) {
showToast("Prompt checked? " + dialog.isPromptCheckBoxChecked());
}
})
.checkBoxPromptRes(R.string.dont_ask_again, false, null)
.show();Creating a list dialog only requires passing in an array of strings. The callback (itemsCallback) is
also very simple.
new MaterialDialog.Builder(this)
.title(R.string.title)
.items(R.array.items)
.itemsCallback(new MaterialDialog.ListCallback() {
@Override
public void onSelection(MaterialDialog dialog, View view, int which, CharSequence text) {
}
})
.show();If autoDismiss is turned off, then you must manually dismiss the dialog in the callback. Auto dismiss is on by default.
You can pass positiveText() or the other action buttons to the builder to force it to display the action buttons
below your list, however this is only useful in some specific cases.
Single choice list dialogs are almost identical to regular list dialogs. The only difference is that
you use itemsCallbackSingleChoice to set a callback rather than itemsCallback. That signals the dialog to
display radio buttons next to list items.
new MaterialDialog.Builder(this)
.title(R.string.title)
.items(R.array.items)
.itemsCallbackSingleChoice(-1, new MaterialDialog.ListCallbackSingleChoice() {
@Override
public boolean onSelection(MaterialDialog dialog, View view, int which, CharSequence text) {
/**
* If you use alwaysCallSingleChoiceCallback(), which is discussed below,
* returning false here won't allow the newly selected radio button to actually be selected.
**/
return true;
}
})
.positiveText(R.string.choose)
.show();If you want to preselect an item, pass an index 0 or greater in place of -1 in itemsCallbackSingleChoice().
Later, you can update the selected index using setSelectedIndex(int) on the MaterialDialog instance,
if you're not using a custom adapter.
If you do not set a positive action button using positiveText(), the dialog will automatically call
the single choice callback when user presses the positive action button. The dialog will also dismiss itself,
unless auto dismiss is turned off.
If you make a call to alwaysCallSingleChoiceCallback(), the single choice callback will be called
every time the user selects/unselects an item.
Like action buttons and many other elements of the Material dialog, you can customize the color of a
dialog's radio buttons. The Builder class contains a widgetColor(), widgetColorRes(),
widgetColorAttr(), and choiceWidgetColor() method. Their names and parameter annotations make them self explanatory.
widgetColor is the same color that affects other UI elements. choiceWidgetColor is specific to
single and multiple choice dialogs, it only affects radio buttons and checkboxes. You provide a
ColorStateList rather than a single color which is used to generate a ColorStateList.
Note that by default, radio buttons will be colored with the color held in colorAccent (for AppCompat)
or android:colorAccent (for the Material theme) in your Activity's theme.
There's also a global theming attribute as shown in the Global Theming section of this README: md_widget_color.
Multiple choice list dialogs are almost identical to regular list dialogs. The only difference is that
you use itemsCallbackMultiChoice to set a callback rather than itemsCallback. That signals the dialog to
display check boxes next to list items, and the callback can return multiple selections.
new MaterialDialog.Builder(this)
.title(R.string.title)
.items(R.array.items)
.itemsCallbackMultiChoice(null, new MaterialDialog.ListCallbackMultiChoice() {
@Override
public boolean onSelection(MaterialDialog dialog, Integer[] which, CharSequence[] text) {
/**
* If you use alwaysCallMultiChoiceCallback(), which is discussed below,
* returning false here won't allow the newly selected check box to actually be selected
* (or the newly unselected check box to be unchecked).
* See the limited multi choice dialog example in the sample project for details.
**/
return true;
}
})
.positiveText(R.string.choose)
.show();If you want to preselect any items, pass an array of indices (resource or literal) in place of null
in itemsCallbackMultiChoice(). Later, you can update the selected indices using setSelectedIndices(Integer[])
on the MaterialDialog instance, if you're not using a custom adapter.
If you do not set a positive action button using positiveText(), the dialog will automatically call
the multi choice callback when user presses the positive action button. The dialog will also dismiss itself,
unless auto dismiss is turned off.
If you make a call to alwaysCallMultiChoiceCallback(), the multi choice callback will be called
every time the user selects/unselects an item.
Like action buttons and many other elements of the Material dialog, you can customize the color of a
dialog's check boxes. The Builder class contains a widgetColor(), widgetColorRes(),
widgetColorAttr(), and choiceWidgetColor() method. Their names and parameter annotations make them self explanatory.
widgetColor is the same color that affects other UI elements. choiceWidgetColor is specific to
single and multiple choice dialogs, it only affects radio buttons and checkboxes. You provide a
ColorStateList rather than a single color which is used to generate a ColorStateList.
Note that by default, radio buttons will be colored with the color held in colorAccent (for AppCompat)
or android:colorAccent (for the Material theme) in your Activity's theme.
There's also a global theming attribute as shown in the Global Theming section of this README: md_widget_color.
If you need to keep track of list items by ID rather than index, you can assign item IDs from an integer array:
new MaterialDialog.Builder(this)
.title(R.string.socialNetworks)
.items(R.array.socialNetworks)
.itemsIds(R.array.itemIds)
.itemsCallback(new MaterialDialog.ListCallback() {
@Override
public void onSelection(MaterialDialog dialog, View view, int which, CharSequence text) {
Toast.makeText(Activity.this, which + ": " + text + ", ID = " + view.getId(), Toast.LENGTH_SHORT).show();
}
})
.show();You can also pass a literal integer array (int[]) in place of an array resource ID.
Like Android's native dialogs, you can also pass in your own adapter via .adapter() to customize
exactly how you want your list to work.
new MaterialDialog.Builder(this)
.title(R.string.socialNetworks)
// second parameter is an optional layout manager. Must be a LinearLayoutManager or GridLayoutManager.
.adapter(new ButtonItemAdapter(this, R.array.socialNetworks), null)
.show();Note that with newer releases, Material Dialogs no longer supports ListView and ListAdapter.
It's about time that everyone uses RecyclerView. Your custom adapters will have to handle item click
events on their own; this library's classes and sample project have some good examples of how that is done correctly.
If you need access to the RecyclerView, you can use the MaterialDialog instance:
MaterialDialog dialog = new MaterialDialog.Builder(this)
...
.build();
RecyclerView list = dialog.getRecyclerView();
// Do something with it
dialog.show();Note that you don't need to be using a custom adapter in order to access the RecyclerView, it's there for single/multi choice dialogs, regular list dialogs, etc.
Custom views are very easy to implement.
boolean wrapInScrollView = true;
new MaterialDialog.Builder(this)
.title(R.string.title)
.customView(R.layout.custom_view, wrapInScrollView)
.positiveText(R.string.positive)
.show();If wrapInScrollView is true, then the library will place your custom view inside of a ScrollView for you.
This allows users to scroll your custom view if necessary (small screens, long content, etc.). However, there are cases
when you don't want that behavior. This mostly consists of cases when you'd have a ScrollView in your custom layout,
including ListViews, RecyclerViews, WebViews, GridViews, etc. The sample project contains examples of using both true
and false for this parameter.
Your custom view will automatically have padding put around it when wrapInScrollView is true. Otherwise
you're responsible for using padding values that look good with your content.
If you need to access a View in the custom view after the dialog is built, you can use getCustomView() of
MaterialDialog. This is especially useful if you pass a layout resource to the Builder, the dialog will
handle the view inflation for you.
MaterialDialog dialog = //... initialization via the builder ...
View view = dialog.getCustomView();If you want to use custom fonts, you can make a call to typeface(String, String) when
using the Builder. This will pull fonts from files in your project's assets/fonts folder. For example,
if you had Roboto.ttf and Roboto-Light.ttf in /src/main/assets/fonts, you would call typeface("Roboto.ttf", "Roboto-Light.ttf").
This method will also handle recycling Typefaces via the TypefaceHelper which you can use in your own project to avoid duplicate
allocations. The raw typeface(Typeface, Typeface) variation will not recycle typefaces, every call will allocate the Typeface again.
There's a global theming attribute available to automatically apply fonts to every Material Dialog in your app, also.
If you want to get a reference to one of the dialog action buttons after the dialog is built and shown (e.g. to enable or disable buttons):
MaterialDialog dialog = //... initialization via the builder ...
View negative = dialog.getActionButton(DialogAction.NEGATIVE);
View neutral = dialog.getActionButton(DialogAction.NEUTRAL);
View positive = dialog.getActionButton(DialogAction.POSITIVE);If you want to update the title of a dialog action button (you can pass a string resource ID in place of the literal string, too):
MaterialDialog dialog = //... initialization via the builder ...
dialog.setActionButton(DialogAction.NEGATIVE, "New Title");Before Lollipop, theming AlertDialogs was basically impossible without using reflection and custom drawables. Since KitKat, Android became more color neutral but AlertDialogs continued to use Holo Blue for the title and title divider. Lollipop has improved even more, with no colors in the dialog by default other than the action buttons. This library makes theming even easier.
By default, Material Dialogs will apply a light theme or dark theme based on the ?android:textColorPrimary
attribute retrieved from the context creating the dialog. If the color is light (e.g. more white), it will
guess the Activity is using a dark theme and it will use the dialog's dark theme. Vice versa for the light theme.
You can manually set the theme used from the Builder#theme() method:
new MaterialDialog.Builder(this)
.content("Hi")
.theme(Theme.DARK)
.show();Or you can use the global theming attribute, which is discussed in the section below. Global theming avoids having to constantly call theme setters for every dialog you show.
Pretty much every aspect of a dialog created with this library can be colored:
new MaterialDialog.Builder(this)
.titleColorRes(R.color.material_red_500)
.contentColor(Color.WHITE) // notice no 'res' postfix for literal color
.linkColorAttr(R.attr.my_link_color_attr) // notice attr is used instead of none or res for attribute resolving
.dividerColorRes(R.color.material_pink_500)
.backgroundColorRes(R.color.material_blue_grey_800)
.positiveColorRes(R.color.material_red_500)
.neutralColorRes(R.color.material_red_500)
.negativeColorRes(R.color.material_red_500)
.widgetColorRes(R.color.material_red_500)
.buttonRippleColorRes(R.color.material_red_500)
.show();The names are self explanatory for the most part. The widgetColor method, discussed in a few other
sections of this tutorial, applies to progress bars, check boxes, and radio buttons. Also note that
each of these methods have 3 variations for setting a color directly, using color resources, and using
color attributes.
Selectors are drawables that change state when pressed or focused.
new MaterialDialog.Builder(this)
.btnSelector(R.drawable.custom_btn_selector)
.btnSelector(R.drawable.custom_btn_selector_primary, DialogAction.POSITIVE)
.btnSelectorStacked(R.drawable.custom_btn_selector_stacked)
.listSelector(R.drawable.custom_list_and_stackedbtn_selector)
.show();The first btnSelector line sets a selector drawable used for all action buttons. The second btnSelector
line overwrites the drawable used only for the positive button. This results in the positive button having
a different selector than the neutral and negative buttons. btnSelectorStacked sets a selector drawable
used when the buttons become stacked, either because there's not enough room to fit them all on one line,
or because you used forceStacked(true) on the Builder. listSelector is used for list items, when
you are NOT using a custom adapter.
Note:
An important note related to using custom action button selectors: make sure your selector drawable references inset drawables like the default ones do - this is important for correct action button padding.
It's probably unlikely you'd want to change gravity of elements in a dialog, but it's possible.
new MaterialDialog.Builder(this)
.titleGravity(GravityEnum.CENTER)
.contentGravity(GravityEnum.CENTER)
.btnStackedGravity(GravityEnum.START)
.itemsGravity(GravityEnum.END)
.buttonsGravity(GravityEnum.END)
.show();These are pretty self explanatory. titleGravity sets the gravity for the dialog title, contentGravity
sets the gravity for the dialog content, btnStackedGravity sets the gravity for stacked action buttons,
itemsGravity sets the gravity for list items (when you're NOT using a custom adapter).
For, buttonsGravity refer to this:
| START (Default) | Neutral | Negative | Positive |
| CENTER | Negative | Neutral | Positive |
| END | Positive | Negative | Neutral |
With no positive button, the negative button takes it's place except for with CENTER.
To see colors that fit the Material design palette, see this page: http://www.google.com/design/spec/style/color.html#color-color-palette
Most of the theming aspects discussed in the above section can be automatically applied to all dialogs you show from an Activity which has a theme containing any of these attributes:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!--
All dialogs will default to Theme.DARK with this set to true.
-->
<item name="md_dark_theme">true</item>
<!--
This overrides the default dark or light dialog background color.
Note that if you use a dark color here, you should set md_dark_theme to
true so text and selectors look visible
-->
<item name="md_background_color">#37474F</item>
<!--
Applies an icon next to the title in all dialogs.
-->
<item name="md_icon">@drawable/ic_launcher</item>

from the colorAccent attribute of AppCompat or android:colorAccent
attribute of the Material theme.
-->
<item name="md_negative_color">#673AB7</item>
<!--
By default, a progress dialog's progress bar, check boxes, and radio buttons
have a color that is derived from the colorAccent attribute of AppCompat or

<!--
The name of font in assets/fonts used everywhere else, like content and list items
(null uses device default). E.g. [your-project]/app/main/assets/fonts/[regular]
-->
<item name="md_regular_font">Roboto-Regular.ttf</item>
</style>The action button color is also derived from the android:colorAccent attribute of the Material theme,
or colorAccent attribute of the AppCompat Material theme as seen in the sample project. Manually setting
the color will override that behavior.
You can directly setup show/cancel/dismiss listeners from the Builder rather than on the resulting
MaterialDialog instance.
Also note that the Builder has a cancelable() method that lets you disable dismissing the dialog
when you tap outside the dialog window.
new MaterialDialog.Builder(this)
.title("Use Google's Location Services?")
.content("Let Google help apps determine location. This means sending anonymous location data to Google, even when no apps are running.")
.positiveText("Agree")
.showListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
}
})
.cancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
}
})
.dismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialog) {
}
})
.show();An input dialog is pretty self explanatory, it retrieves input from the user of your application with an input field (EditText). You can also display content above the EditText if you desire.
new MaterialDialog.Builder(this)
.title(R.string.input)
.content(R.string.input_content)
.inputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD)
.input(R.string.input_hint, R.string.input_prefill, new MaterialDialog.InputCallback() {
@Override
public void onInput(MaterialDialog dialog, CharSequence input) {
// Do something
}
}).show();The input dialog will automatically handle focusing the EditText and displaying the keyboard to allow the user to immediately enter input. When the dialog is closed, the keyboard will be automatically dismissed.
Note that the dialog will force the positive action button to be visible, when it's pressed the input is submitted to the callback.
Also Note that the call to inputType() is optional.
Like action buttons and many other elements of the Material dialog, you can customize the color of a
input dialog's EditText. The Builder class contains a widgetColor(), widgetColorRes(),
and widgetColorAttr() method. Their names and parameter annotations make them self explanatory.
Note that by default, EditTexts will be colored with the color held in colorAccent (for AppCompat)
or android:colorAccent (for the Material theme) in your Activity's theme.
There's also a global theming attribute as shown in the Global Theming section of this README: md_widget_color.
The code below will show a little indicator in the input dialog that tells the user how many characters they've typed. If they type less than 2 characters, or more than 20, the dialog won't allow the input to be submitted. It will also color the input field and character counter in error color passed for the third parameter.
If you pass 0 for the min length, there will be no min length. If you pass -1 for the max length, there will be no max length. If you don't pass a third parameter at all, it will default to Material red.
new MaterialDialog.Builder(this)
.title(R.string.input)
.inputRangeRes(2, 20, R.color.material_red_500)
.input(null, null, new MaterialDialog.InputCallback() {
@Override
public void onInput(MaterialDialog dialog, CharSequence input) {
// Do something
}
}).show();*Note that inputRangeRes(int, int, int) takes a color resource ID for the third parameter, while
inputRange(int, int, int) takes a literal color integer for the second parameter. You can use either one, or use
the variation that doesn't take a third parameter at all.
The easiest way to invalidate (enable or disable the EditText based on whether you think the input is acceptable)
input dialogs is to call alwaysCallInputCallback() from the Builder so that the callback is invoked
every time the user changes their input. From there, you can constantly check what they've typed. If you
decide they shouldn't be able to submit that, you can disable the submit button using this from within the callback:
dialog.getActionButton(DialogAction.POSITIVE).setEnabled(false);This library allows you to display progress dialogs with Material design that even use your app's accent color to color the progress bars (if you use AppCompat to theme your app, or the Material theme on Lollipop).
Normally, ObjectAnimator in the context it's used in this library (for custom progress drawables) would
need special proguard rules so that certain elements aren't removed when your app is built in release mode.
Luckily, AAR packages are allowed to specify proguard rules that get included in apps that depend on them.
So you do not need to worry about including any Proguard rules in order to ensure progress bars behave well.
This will display the classic progress dialog with a spinning circle, see the sample project to see it in action:
new MaterialDialog.Builder(this)
.title(R.string.progress_dialog)
.content(R.string.please_wait)
.progress(true, 0)
.show();If a dialog is not indeterminate, it displays a horizontal progress bar that increases up until a max value. The comments in the code explain what this does.
// Create and show a non-indeterminate dialog with a max value of 150
// If the showMinMax parameter is true, a min/max ratio will be shown to the left of the seek bar.
boolean showMinMax = true;
MaterialDialog dialog = new MaterialDialog.Builder(this)
.title(R.string.progress_dialog)
.content(R.string.please_wait)
.progress(false, 150, showMinMax)
.show();
// Loop until the dialog's progress value reaches the max (150)
while (dialog.getCurrentProgress() != dialog.getMaxProgress()) {
// If the progress dialog is cancelled (the user closes it before it's done), break the loop
if (dialog.isCancelled()) break;
// Wait 50 milliseconds to simulate doing work that requires progress
try {
Thread.sleep(50);
} catch (InterruptedException e) {
break;
}
// Increment the dialog's progress by 1 after sleeping for 50ms
dialog.incrementProgress(1);
}
// When the loop exits, set the dialog content to a string that equals "Done"
dialog.setContent(getString(R.string.done));See the sample project for this dialog in action, with the addition of threading.
By default, indeterminate progress dialogs use a circular progress indicator. From the Builder,
you can tell the dialog that it needs to use a horizontal indicator when displaying an indeterminate progress
dialog:
new MaterialDialog.Builder(this)
.title(R.string.progress_dialog)
.content(R.string.please_wait)
.progress(true, 0)
.progressIndeterminateStyle(true)
.show();Like action buttons and many other elements of the Material dialog, you can customize the color of a
progress dialog's progress bar. The Builder class contains a widgetColor(), widgetColorRes(),
and widgetColorAttr() method. Their names and parameter annotations make them self explanatory.
Note that by default, progress bars will be colored with the color held in colorAccent (for AppCompat)
or android:colorAccent (for the Material theme) in your Activity's theme.
There's also a global theming attribute as shown in the Global Theming section of this README: md_widget_color.
Like the stock ProgressDialog, you can format the progress min/max numbers and the percentage indicator
of determinate dialogs.
MaterialDialog dialog = new MaterialDialog.Builder(this)
.progress(false, 150, true)
...
.progressNumberFormat("%1d/%2d")
.progressPercentFormat(NumberFormat.getPercentageInstance())
...
.show();The values passed above are the default.
You can use the MDTintHelper class to dynamically color check boxes, radio buttons, edit texts, and progress bars
(to get around not being able to change styles.xml at runtime). It is used in the library to dynamically color
UI elements to match your set widgetColor.
If you don't want the dialog to automatically be dismissed when an action button is pressed or when the user selects a list item:
MaterialDialog dialog = new MaterialDialog.Builder(this)
// ... other initialization
.autoDismiss(false)
.show();The Builder is used like this:
// Pass a context, along with the title of the dialog
new ColorChooserDialog.Builder(this, R.string.color_palette)
.titleSub(R.string.colors) // title of dialog when viewing shades of a color
.accentMode(accent) // when true, will display accent palette instead of primary palette
.doneButton(R.string.md_done_label) // changes label of the done button
.cancelButton(R.string.md_cancel_label) // changes label of the cancel button
.backButton(R.string.md_back_label) // changes label of the back button
.preselect(accent ? accentPreselect : primaryPreselect) // optionally preselects a color
.dynamicButtonColor(true) // defaults to true, false will disable changing action buttons' color to currently selected color
.show(this); // an AppCompatActivity which implements ColorCallbackThe Activity/Fragment you show the dialog in must implement ColorCallback:
public class MyActivity implements ColorChooserDialog.ColorCallback {
// ...
@Override
public void onColorSelection(ColorChooserDialog dialog, @ColorInt int color) {
// TODO
}
}You can also specify custom colors to be displayed if you don't want to use the built-in primary or accent color palettes (which consist of the entire Material Design Color Palette):
int[] primary = new int[] {
Color.parseColor("#F44336")
};
int[][] secondary = new int[][] {
new int[] { Color.parseColor("#EF5350"), Color.parseColor("#F44336"), Color.parseColor("#E53935") }
};
new ColorChooserDialog.Builder(this, R.string.color_palette)
.titleSub(R.string.colors)
.customColors(primary, secondary)
.show(this);The first parameter for primary colors can also take an array resource (R.array.colors), which can be
seen in the sample project. If you pass null for the second parameter, there will be no sub levels displayed
for top level colors.
Since the ColorChooserDialog is a DialogFragment, it attaches to your Activity/Fragment through its FragmentManager.
ColorChooserDialog has a utility method called findVisible(AppCompatActivity, String) that will
find a visible color chooser if any is visible:
ColorChooserDialog primary = ColorChooserDialog.findVisible(getSupportFragmentManager(), ColorChooserDialog.TAG_PRIMARY);
ColorChooserDialog accent = ColorChooserDialog.findVisible(getSupportFragmentManager(), ColorChooserDialog.TAG_ACCENT);
ColorChooserDialog custom = ColorChooserDialog.findVisible(getSupportFragmentManager(), ColorChooserDialog.TAG_CUSTOM);By default, color chooser dialogs allow the user to input a custom color using RGB sliders or a Hexadecimal input field. This can be disabled if you don't want users to be able to use it:
new ColorChooserDialog.Builder(this, R.string.color_palette)
.allowUserColorInput(false)
.customButton(R.string.md_custom_label)
.presetsButton(R.string.md_presets_label)
.show(this);If you want the user to be able to input a custom color, but don't want them to be able to change transparency (alpha):
new ColorChooserDialog.Builder(this, R.string.color_palette)
.allowUserColorInputAlpha(false)
.customButton(R.string.md_custom_label)
.presetsButton(R.string.md_presets_label)
.show(this);Android's EditTextPreference, ListPreference, and MultiSelectListPreference allow you to associate a preference activity's settings
with user input that's received through typing or selection. Material Dialogs includes MaterialEditTextPreference,
MaterialListPreference, and MaterialMultiSelectListPreference classes that can be used in your preferences XML to automatically use Material-themed
dialogs. See the sample project for details.
By default, all of these preference classes will set their layout to R.layout.md_preference_custom. If you
don't want a default layout to be set, you can provide an attribute on the preferences in your XML:
app:useStockLayout="true"
The Builder is used like this:
new FileChooserDialog.Builder(this)
.initialPath("/sdcard/Download") // changes initial path, defaults to external storage directory
.mimeType("image/*") // Optional MIME type filter
.extensionsFilter(".png", ".jpg") // Optional extension filter, will override mimeType()
.tag("optional-identifier")
.goUpLabel("Up") // custom go up label, default label is "..."
.show(this); // an AppCompatActivity which implements FileCallbackThe Activity/Fragment you show the dialog in must implement FileCallback:
public class MyActivity implements FileChooserDialog.FileCallback {
// ...
@Override
public void onFileSelection(FileChooserDialog dialog, File file) {
// TODO
final String tag = dialog.getTag(); // gets tag set from Builder, if you use multiple dialogs
}
}The Builder is used like this:
// Pass AppCompatActivity which implements FolderCallback
new FolderChooserDialog.Builder(this)
.chooseButton(R.string.md_choose_label) // changes label of the choose button
.initialPath("/sdcard/Download") // changes initial path, defaults to external storage directory
.tag("optional-identifier")
.goUpLabel("Up") // custom go up label, default label is "..."
.show(this);The Activity/Fragment you show the dialog in must implement FolderCallback:
public class MyActivity implements FolderChooserDialog.FolderCallback {
// ...
@Override
public void onFolderSelection(FolderChooserDialog dialog, File folder) {
// TODO
final String tag = dialog.getTag(); // gets tag set from Builder, if you use multiple dialogs
}
}Optionally, you can allow users to have the ability to create new folders from this dialog:
new FolderChooserDialog.Builder(this)
.chooseButton(R.string.md_choose_label) // changes label of the choose button
.initialPath("/sdcard/Download") // changes initial path, defaults to external storage directory
.tag("optional-identifier")
.allowNewFolder(true, R.string.new_folder) // pass 0 in the second parameter to use default button label
.show(this);Simple List Dialogs are a specific style of list dialogs taken from the Material Design Guidelines: https://www.google.com/design/spec/components/dialogs.html#dialogs-simple-dialogs
This library's implementation is just a pre-made adapter that you can pass to the MaterialDialog.Builder.
final MaterialSimpleListAdapter adapter = new MaterialSimpleListAdapter(new MaterialSimpleListAdapter.Callback() {
@Override
public void onMaterialListItemSelected(MaterialDialog dialog, int index, MaterialSimpleListItem item) {
// TODO
}
});
adapter.add(new MaterialSimpleListItem.Builder(this)
.content("[email protected]")
.icon(R.drawable.ic_account_circle)
.backgroundColor(Color.WHITE)
.build());
adapter.add(new MaterialSimpleListItem.Builder(this)
.content("[email protected]")
.icon(R.drawable.ic_account_circle)
.backgroundColor(Color.WHITE)
.build());
adapter.add(new MaterialSimpleListItem.Builder(this)
.content(R.string.add_account)
.icon(R.drawable.ic_content_add)
.iconPaddingDp(8)
.build());
new MaterialDialog.Builder(this)
.title(R.string.set_backup)
.adapter(adapter, null)
.show();
