    private boolean check = false;
    private static Context mContext;

    RemoteViews remoteViews;
    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
            int[] appWidgetIds) {
        // TODO Auto-generated method stub
        System.out.println("ON UPDATE");
        //mContext = context;
        //widgetId = appWidgetIds;
        remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.testwidget);
        Intent active = new Intent(context, HelloWidget.class);
        active.setAction(ACTION_WIDGET_RECEIVER);
        active.putExtra("widgetids", appWidgetIds);
        PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context,
                REQUEST_CODE_ONE, active, 0);
        remoteViews.setOnClickPendingIntent(R.id.ll, actionPendingIntent);
        appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
         System.out.println("ONRECEIVEEEEEEEEE");
        final String action = intent.getAction();
        System.out.println("ACTION "+action);
        if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
            final int appWidgetId = intent.getExtras().getInt(
                    AppWidgetManager.EXTRA_APPWIDGET_ID,
                    AppWidgetManager.INVALID_APPWIDGET_ID);
            if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
                this.onDeleted(context, new int[] { appWidgetId });
            }
        }else{
            System.out.println("HERE I AM");
            if(!check){
                check = true;
            }else{
                check = false;
            }
            updateWidget(context);
        }
    }
   
    private void updateWidget(Context context){
        System.out.println("INSIDE MY UPDATE WIDGET");
        //RemoteViews views = null;
        System.out.println(" PACK ANEM "+context.getPackageName());
        //System.out.println(" ");
        if(check){
            System.out.println(" Inside if");
            remoteViews = new RemoteViews(context.getPackageName(),
                        R.layout.hellowidget);
        }else{
            System.out.println(" Inside else");
            remoteViews = new RemoteViews(context.getPackageName(),
                        R.layout.testwidget);
        }
        ComponentName localComponentName = new ComponentName(context, HelloWidget.class);
        AppWidgetManager.getInstance(context).updateAppWidget(localComponentName, remoteViews);
        //AppWidgetManager mgr = AppWidgetManager.getInstance(context);
        //mgr.updateAppWidget(widgetId, remoteViews);
    }
}

this is my hellowidget.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@layout/myshape">

    <Button
        android:id="@+id/tv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="@string/app_name"
        android:gravity="center_vertical|center_horizontal"
        />
