You're almost there with your code. The pending intent should relate to something in your code which would update the widget.
You don't have to wait for onUpdate (which is called by "the system" when needed), rather you can get the AppWidgetManager yourself and make an update at any time. You will need to either know the widget Id(s) you're going to update, or update all of them by using AppWidgetManager.update that takes a ComponentName. -- Kostya 2011/6/24 Hitendrasinh Gohil <[email protected]> > Hi, > > I have made three classess. > > MainActivity > AppWidgetService > AppWidget > > As i am able to update widget from activity through service.I have one > button in wiget.i want to update widget onclick of the button. > Here is my code for AppWidgetService. > package com.widget.main; > > import android.app.IntentService; > import android.app.PendingIntent; > import android.appwidget.AppWidgetManager; > import android.content.ComponentName; > import android.content.Intent; > import android.widget.RemoteViews; > > public class AppWidgetService extends IntentService { > > public AppWidgetService() { > super("AppWidgetService"); > // TODO Auto-generated constructor stub > } > > @Override > protected void onHandleIntent(Intent intent) { > ComponentName componentName = new ComponentName(this, > AppWidget.class); > RemoteViews remoteViews = new RemoteViews("com.widget.main", > R.layout.appwidget); > AppWidgetManager appWidgetManager = > AppWidgetManager.getInstance(this); > > remoteViews.setTextViewText(R.id.TextView01, > > MainActivity.listarray[MainActivity.currentIndex]); > > Intent activityIntent = new Intent(this, > MainActivity.class); > PendingIntent pendingIntent = PendingIntent.getActivity( > getApplicationContext(), 0, activityIntent, > PendingIntent.FLAG_UPDATE_CURRENT); > remoteViews.setOnClickPendingIntent(R.id.ImageView01, > pendingIntent); > > /* Intent serviceIntent = new Intent(this, > AppWidgetService.class); > PendingIntent pendingserviceIntent = > PendingIntent.getService( > getApplicationContext(), 0, > serviceIntent,PendingIntent.FLAG_UPDATE_CURRENT); > > > > remoteViews.setOnClickPendingIntent(R.id.ImageButton01,pendingserviceIntent);*/ > > appWidgetManager.updateAppWidget(componentName, > remoteViews); > } > > } > and here is my code for widget class. > package com.widget.main; > > import android.appwidget.AppWidgetManager; > import android.appwidget.AppWidgetProvider; > import android.content.Context; > import android.content.Intent; > > public class AppWidget extends AppWidgetProvider > { > public void onUpdate(Context context,AppWidgetManager > appWidgetManager,int[] appWidgetIds) > { > super.onUpdate(context, appWidgetManager, appWidgetIds); > context.startService(new > Intent(context,AppWidgetService.class)); > } > } > > so how can i update widget when click on widget button? > > -- > You received this message because you are subscribed to the Google > Groups "Android Developers" group. > To post to this group, send email to [email protected] > To unsubscribe from this group, send email to > [email protected] > For more options, visit this group at > http://groups.google.com/group/android-developers?hl=en -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
