Now I have to develop one widget f

Answer 1

I am finding couple of days I got somehow the solution. So I am sharing my idea.

This site has been very useful for me.

http://kasperholtze.com/android/how-to-make-a-simple-android-widget/

I made some changes and did my work.

Requirement solution:

1. Make Receiver and put into manifest permission like this.

2. In my side require top TextView click so can make using TextView id in onUpdate().

    remoteViews = new RemoteViews(context.getPackageName(),R.layout.widget_lay);

    Intent intent = new Intent(context, TestActivity.class);
    intent.setAction("callActivity");
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
    remoteViews.setOnClickPendingIntent(R.id.widget_textview, pendingIntent); 
    appWidgetManager.updateAppWidget(new ComponentName(context,WatchWidget.class), remoteViews);

3. I want to call database and fetch record and display it. Now question what about update?

So I have used timer class and run every 1000sec because of over widget is always update 30min(may be).

@Override
public void onUpdate( final Context context, final AppWidgetManager appWidgetManager, final int[] appWidgetIds )
{

    this.appWidgetManager = appWidgetManager;
    try {
        Timer timer = new Timer();
        timer.scheduleAtFixedRate(new MyTime(context, appWidgetManager,appWidgetIds), 1, 1000);

    } catch (Exception e) {
        System.out.println("Exception:");
    }
    updateSwitch1(context, appWidgetManager, appWidgetIds[0]);

}
