android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginTop="@dimen/activity_vertical_margin"
android:entries="@array/item_arrays"
android:prompt="@string/spinner_prompt"
android:spinnerMode="dropdown" />Implement PopupDismissListener interface.
public class MainActivity extends Activity implements PopupDismissListener {
// TODO override interface's method
@Override
public void onDismiss(DialogInterface dialog) {
// you could process drop down case and dialog case seperately if needed
}
}Call PopupDismissCatchableSpinner.addOnPopupDismissListener(PopupDismissListener listener) and you are able to catch show/dismiss events
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// ...
spinner1 = (PopupDismissCatchableSpinner) findViewById(R.id.spinner1);
spinner1.addOnPopupDismissListener(this);
// ...
