public onButtonLoaded_1(args) {
    let btn = args.object as Button;
    let androidButton = btn.android as android.widget.Button

    androidButton.setOnKeyListener(new android.view.View.OnKeyListener({
        onKey: function (view, keyCode, keyEvent) {
          if (
            keyCode == android.view.KeyEvent.KEYCODE_DPAD_CENTER &&
            keyEvent.getAction() == android.view.KeyEvent.ACTION_DOWN
          ) {
            console.log("DPAD Center Pressed");
          }
