Button is not Worked at android widget

Question

In the onUpdate function

    RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.a_g_p_s_widget);
    Intent it_1 = new Intent(context, Widget.class);
    it_1.setAction(context.getResources().getString(R.string.ACTION_BTN_CHILD_1));
    Intent it_2 = new Intent(context, Widget.class);
    it_2.setAction(context.getResources().getString(R.string.ACTION_BTN_CHILD_2));

    PendingIntent pdIt_1 = PendingIntent.getBroadcast(context, 0, it_1, 0);
    PendingIntent pdIt_2 = PendingIntent.getBroadcast(context, 0, it_2, 0);
    rv.setOnClickPendingIntent(R.id.btnFindChild_1, pdIt_1);
    rv.setOnClickPendingIntent(R.id.btnFindChild_1, pdIt_2);

    for (int appWidgetId : appWidgetIds) {
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }


    In the 'onReceive' function

    String strAction = intent.getAction();

    Toast.makeText(context, "onReceive event is occurred action = " + strAction, Toast.LENGTH_SHORT).show();
    AppWidgetManager appMgr = AppWidgetManager.getInstance(context);
    initUI(context, appMgr, appMgr.getAppWidgetIds(new ComponentName(context, getClass())));
    if(strAction.equals(context.getResources().getString(R.string.ACTION_BTN_CHILD_1))){
        Log.d(TAG, "Button 1 is clicked");
        Toast.makeText(context, "Button 1 is clicked", Toast.LENGTH_SHORT).show();
    } else if(strAction.equals(context.getResources().getString(R.string.ACTION_BTN_CHILD_2))){
        Log.d(TAG, "Button 2 is clicked");
        Toast.makeText(context, "Button 2 is clicked", Toast.LENGTH_SHORT).show();
    } else{
        Log.d(TAG, "No case");
    }

This is my source code for the widget. But the button is not working. Please help! I didn't know why are not worked.

I have already added action to manifest file in my project. Other messages can receive. (Enable, update)
