android ---appWidget--broadcast

exampleAppzWidget.java

package com.example.exampleAppWidget;import android.app.PendingIntent;import android.appwidget.AppWidgetManager;import android.appwidget.AppWidgetProvider;import android.content.Context;import android.content.Intent;import android.widget.RemoteViews;public class exampleAppWidget extends AppWidgetProvider { private static final String APP_UPDATE_ACTION = "com.example.exampleAppzWidget.APP_UPDATE";@Overridepublic void onUpdate(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds) {// TODO Auto-generated method stubIntent intent = new Intent();intent.setAction(APP_UPDATE_ACTION);PendingIntent pendingIntent = PendingIntent.getBroadcast(context,0,intent,0);RemoteViews remoteViews = new RemoteViews(context.getPackageName(),R.layout.example_appwidget_provider);remoteViews.setOnClickPendingIntent(R.id.widgetButtonId,pendingIntent);appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);super.onUpdate(context, appWidgetManager, appWidgetIds);}@Overridepublic void onDeleted(Context context, int[] appWidgetIds) {// TODO Auto-generated method stubSystem.out.println("delete");super.onDeleted(context, appWidgetIds);}@Overridepublic void onDisabled(Context context) {// TODO Auto-generated method stubSystem.out.println("disabled");super.onDisabled(context);}@Overridepublic void onEnabled(Context context) {// TODO Auto-generated method stubSystem.out.println("endabled");super.onEnabled(context);}@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubsuper.onReceive(context, intent);String action = intent.getAction();if(APP_UPDATE_ACTION.equals(action)){System.out.println("receive-->" + action);}} }

 

然后在Mainfest中注册一个自定义的action

 

  <intent-filter>
          <action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>
        </intent-filter>
