How to create Listview with help of remoteview?

Question

I am trying to make dynamic listview in widget with help of remoteview, as I wanted this listview of application icons in a widget. I want to show incoming notifications from all apps which are separated application wise. I want to create standing notification list and when user clicks on application icon from listview, that particular notification will be displayed. I am using API 19 for getting all notification and also succeeded but I don't know how I can create Listview in widget with Remoteview and also with drawables(Icons).

Have you search or try with other examples having ListView in widget? Please check the Weather Widget demo available on github.

Code:

    public class MyWidgetProvider extends AppWidgetProvider {

    private static HandlerThread sWorkerThread;
    private static Handler sWorkerQueue;

    public MyWidgetProvider() {
        // Start the worker thread
        sWorkerThread = new HandlerThread("MyWidgetProvider-worker");
        sWorkerThread.start();
        sWorkerQueue = new Handler(sWorkerThread.getLooper());
    }

    public void onUpdate(Context context, final AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        for (int i = 0; i < appWidgetIds.length; ++i) {
            ...
            final RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
            views.setRemoteAdapter(R.id.lvWidget, svcIntent);

            sWorkerQueue.postDelayed(new Runnable() {

                @Override
                public void run() {
                    // TODO Auto-generated method stub
                    views.setScrollPosition(R.id.list, 3);
                    appWidgetManager.partiallyUpdateAppWidget(appWidgetIds[i], views);
                }

            }, 1000);

            appWidgetManager.updateAppWidget(appWidgetIds[i], views);
            ...
        }
    }
}

Which will behave like below:

Please check the github project and above sample code.
