کنترل button در ویجت

انصافا نخوندید، کافیه setOnClickPendingIntent رو توی صفحه جستجو کنید. اینم یه مثال:

Manifest

<receiver android:name=".ButtonWidget">
    <intent-filter>
        <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        <action android:name="com.app.widget.TOAST" />
    </intent-filter>
    <meta-data
        android:name="android.appwidget.provider"
        android:resource="@xml/button_widget_info" />
</receiver>

WidgetClass

public class ButtonWidget extends AppWidgetProvider {

    static final String TOAST_ACTION = "com.app.widget.TOAST";
    static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
                                int appWidgetId) {
        Intent i = new Intent(TOAST_ACTION);
        PendingIntent pi = PendingIntent.getBroadcast(context,0,i,0);
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.button_widget);
        views.setOnClickPendingIntent(R.id.button,pi);
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);
        if (TOAST_ACTION.equals(intent.getAction())) {
            Toast.makeText(context, "Button Clicked", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        // There may be multiple widgets active, so update all of them
        for (int appWidgetId : appWidgetIds) {
            updateAppWidget(context, appWidgetManager, appWidgetId);
        }
    }
}
