    public static final String MERCHANT_ITEM = "com.mobistech.mobistechsmart.Widget.MERCHANT_ITEM"; 

    @Override 
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, 
         int[] appWidgetIds) { 
     final int N = appWidgetIds.length; 

     for (int i = 0; i < N; ++i) { 
      RemoteViews remoteViews = updateWidgetListView(context, 
        appWidgetIds[i]); 
      appWidgetManager.updateAppWidget(appWidgetIds[i], remoteViews); 
     } 
     super.onUpdate(context, appWidgetManager, appWidgetIds); 
    } 



     private RemoteViews updateWidgetListView(Context context, int appWidgetId) { 

     //which layout to show on widget 
     RemoteViews remoteViews = new RemoteViews(context.getPackageName(), 
       R.layout.widget_layout); 

     Intent svcIntent = new Intent(context, WidgetService.class); 
     svcIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); 

     svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME))); 
     remoteViews.setRemoteAdapter(appWidgetId, R.id.listViewWidget, 
       svcIntent); 
     remoteViews.setEmptyView(R.id.listViewWidget, R.id.empty_view); 


     //When item is clicked on ListView 



     Intent startActivityIntent = new Intent(context, BroadCast.class); 
     PendingIntent startActivityPendingIntent = PendingIntent.getBroadcast(context, 0, startActivityIntent, PendingIntent.FLAG_UPDATE_CURRENT); 
     remoteViews.setPendingIntentTemplate(R.id.listViewWidget, startActivityPendingIntent); 

     return remoteViews; 
    } 

} 

WidgetService.class

public class WidgetService extends RemoteViewsService { 
    /* 
    * So pretty simple just defining the Adapter of the listview 
    * here Adapter is ListProvider 
    * */ 

    @Override 
    public RemoteViewsFactory onGetViewFactory(Intent intent) { 
     int appWidgetId = intent.getIntExtra(
       AppWidgetManager.EXTRA_APPWIDGET_ID, 
       AppWidgetManager.INVALID_APPWIDGET_ID); 

     return (new ListProvider(this.getApplicationContext(), intent)); 
    } 
} 

ListProvider.class

public class ListProvider implements RemoteViewsFactory { 
    private List<Device> listItemList = new ArrayList<Device>(); 
    private Context context = null;

    public ListProvider(Context context, Intent intent) { 
     this.context = context; 
     appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, 
       AppWidgetManager.INVALID_APPWIDGET_ID); 

     populateListItem(); 
    } 

    private void populateListItem() { 
     DatabaseHandler db=new DatabaseHandler(context); 
     listItemList=db.getAllDevices(); 
    } 

    @Override 
    public int getCount() { 
     return listItemList.size(); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    /* 
    *Similar to getView of Adapter where instead of View 
    *we return RemoteViews 
    * 
    */ 
    @Override 
    public RemoteViews getViewAt(int position) { 

     final RemoteViews remoteView = new RemoteViews(
       context.getPackageName(), R.layout.list_row); 
     Device device = listItemList.get(position); 
     remoteView.setTextViewText(R.id.row_txt,device.getName()); 
     remoteView.setImageViewResource(R.id.row_image, context.getResources().getIdentifier(device.getIconName(), "drawable", context.getPackageName())); 


     Intent fillInIntent = new Intent(); 
     fillInIntent.putExtra(WidgetProvider.TOAST_ACTION, position); 
     remoteView.setOnClickFillInIntent(R.id.row_txt, fillInIntent); 


     return remoteView; 
    } 


    @Override 
    public RemoteViews getLoadingView() { 
     return null; 
    } 

    @Override 
    public int getViewTypeCount() { 
     return 1; 
    } 

    @Override 
    public boolean hasStableIds() { 
     return true; 
    } 

    @Override 
    public void onCreate() { 
    } 

    @Override 
    public void onDataSetChanged() { 
    } 

    @Override 
    public void onDestroy() { 
    } 
}
