AppWidget如何打开一个Acticity?

在Android手机的AppWidget上如何打开一个Activity?

一、onUpdate()函数中

 //创建一个Intent对象
  Intent intent = new Intent(context,MyActivity.class);
  intent.setAction(broadCastString);

  //设置pendingIntent的作用
  PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
  RemoteViews remoteViews = new RemoteViews(context.getPackageName(),R.layout.appwidgetlayout);

  //绑定事件
  remoteViews.setOnClickPendingIntent(R.id.image_wifi,pendingIntent);

  //更新Appwidget
  appWidgetManager.updateAppWidget(appWidgetIds,remoteViews);

 

二、AndroidManifest.xml中注册MyActivity

        <activity
            android:name="com.example.myappwidget.MyActivity"
            android:label="hehe" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

大体的步骤是如此，具体你可以根据自己的要求做出修改
