Empty view cannot be set while there is no items in the list

[suji099]

When there is no items in the list view i have to set an emptyview .In the current code there is no option to set an empty view .

The PullToRefreshListView does not override #setEmptyView of ListView, so you can just use http://developer.android.com/reference/android/widget/AdapterView.html#setEmptyView(android.view.View) or set the empty view in XML like you would on any other regular ListView.

I have to agree that this is a bug. When using setEmptyView, you lose the functionality to pull to refresh when the list is indeed empty. Also it is very gltchy when refreshing (as the list goes empty for a brief second while updating and you see the empty view).

Yes, you are right. I'm re-opening the issue and will look into it ASAP.

I thought I'd just go ahead and put my solution:

In PullToRefreshListView add the following:

private TextView emptyView;
private String noItemsText;

public void removeEmptyHeaderView() {
    if(getHeaderViewsCount()!=1) {
        removeHeaderView(emptyView);
    }
}

//modify
public void onRefreshComplete() {
state = State.PULL_TO_REFRESH;
if (emptyView != null) {
if (getAdapter().isEmpty()) {
if (getHeaderViewsCount() == 1) {
emptyView.setHeight(getHeight());
emptyView.setText(noItemsText);
addHeaderView(emptyView);
}
} else {
if (getHeaderViewsCount() == 2) {
removeHeaderView(emptyView);
}
}
}
resetHeader();
}

//in init() add
noItemsText = getContext().getString(R.string.ptr_no_items_text); //modify string xml file

    emptyView = buildDefaultEmptyView();

//add this method - this can be refactored to use styles
private TextView buildDefaultEmptyView() {
TextView emptyView = new TextView(getContext());
emptyView.setText(noItemsText);
emptyView.setLayoutParams(new AbsListView.LayoutParams(AbsListView.LayoutParams.FILL_PARENT, AbsListView.LayoutParams.FILL_PARENT));
emptyView.setGravity(Gravity.CENTER_VERTICAL|Gravity.CENTER_HORIZONTAL);
emptyView.setTextColor(Color.BLACK);
emptyView.setTextSize(20);
return emptyView;
}

public void setNoItemsText(String noItemsText) {
this.noItemsText = noItemsText;
}

public void setEmtpyView(TextView view) {
this.emptyView = view;
}

This can be refactored but simply gives a default empty view with a modifiable TextView

A pull request would be nice...

I need the setEmptyView functionality and would be really happy if it´s solved. The solution vincentjames501 provided works, but not initially. The list is empty from the beginning and the text is not shown until a refresh is done. I want to tell the user that he needs to refresh. I tried to call the onRefreshComplete() manually but it will not update the header for some reason?
