How do I create an Android Spinner as a popup?

Question

I want to bring up a spinner dialog when the user taps a menu item to allow the user to select an item.

Do I need a separate dialog for this or can I use Spinner dir

Answer 1

Here is an Spinner subclass which overrides performClick() to show a dialog instead of a dropdown. No XML required. Give it a try, let me know if it works for you.

public class DialogSpinner extends Spinner {
    public DialogSpinner(Context context) {
        super(context);
    }

    @Override 
    public boolean performClick() {
        new AlertDialog.Builder(getContext()).setAdapter((ListAdapter) getAdapter(), 
            new DialogInterface.OnClickListener() {
                @Override public void onClick(DialogInterface dialog, int which) {
                    setSelection(which);
                    dialog.dismiss();
                }
            }).create().show();
        return true;
    }
}
