A customizable and easy to use bottom bar view with sleek animations.
Download the app showcasing the examples: demo.apk
Add the following dependency to your build.gradle:
implementation 'nl.joery.animatedbottombar:library:1.0.0'
Define AnimatedBottomBar
in your XML layout with custom attributes.
<nl.joery.animatedbottombar.AnimatedBottomBar
android:id="@+id/bottom_bar"
android:background="#FFF"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:abb_selectedTabType="text"
app:abb_indicatorAppearance="round"
app:abb_indicatorMargin="16dp"
app:abb_indicatorHeight="4dp"
app:abb_tabs="@menu/tabs"
app:abb_selectedIndex="1" />
Create a file named tabs.xml
in the res/menu/
resources folder:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/tab_home"
android:icon="@drawable/home"
android:title="@string/home" />
<item
android:id="@+id/tab_alarm"
android:icon="@drawable/alarm"
android:title="@string/alarm" />
<item
android:id="@+id/tab_bread"
android:icon="@drawable/bread"
android:title="@string/bread" />
<item
android:id="@+id/tab_cart"
android:icon="@drawable/cart"
android:title="@string/cart" />
</menu>
Get notified when the selected tab changes:
bottom_bar.setOnTabSelectListener(object : AnimatedBottomBar.OnTabSelectListener {
override fun onTabSelected(
lastIndex: Int,
lastTab: AnimatedBottomBar.Tab?,
newIndex: Int,
newTab: AnimatedBottomBar.Tab
) {
Log.d("TAB_SELECTED", "Selected index: $newIndex, title: ${newTab.title}")
}
})
Short overview on how to manage tabs using code.
// Creating a tab by passing values
val bottomBarTab1 = AnimatedBottomBar.createTab(drawable, "Tab 1")
// Creating a tab by passing Resource IDs
val bottomBarTab2 = AnimatedBottomBar.createTab(R.drawable.ic_home, R.string.tab_2)
// Adding a tab at the end
AnimatedBottomBar.addTab(bottomBarTab1)
// Add a tab at a specific position
AnimatedBottomBar.addTabAt(1, bottomBarTab2)
// Removing a tab by object reference
val tabToRemove = AnimatedBottomBar.tabs[1]
AnimatedBottomBar.removeTab(tabToRemove)
// Removing a tab at a specific position
AnimatedBottomBar.removeTabAt(tabPosition)
// Selecting a tab by object reference
val tabToSelect = AnimatedBottomBar.tabs[1]
AnimatedBottomBar.selectTab(tabToSelect)
// Selecting a tab at a specific position
AnimatedBottomBar.selectTabAt(1)
Could be useful for example restricting access to a premium area.
bottom_bar.setOnTabInterceptListener(object : AnimatedBottomBar.OnTabInterceptListener {
override fun onTabIntercepted(
lastIndex: Int,
lastTab: AnimatedBottomBar.Tab?,
newIndex: Int,
newTab: AnimatedBottomBar.Tab
): Boolean {
if (newTab.id == R.id.tab_pro_feature && !hasProVersion) {
// e.g. show a dialog
return true;
}
return false
}
})

For the awesome concept :) - https://github.com/iammert/ReadableBottomBar
Awesome library, but it was lacking the configurability I needed for my own project.
