Android – 如何发送GCM推送通知以及要加载哪些活动的说明？

@Override
      protected void onmessage(Context ctxt,Intent messagE) 
      {           
        Bundle extras=message.getExtras();

        try
        {
            String question_id = extras.getString("question_id");
//          SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences( this );
//          Intent intent = new Intent(ctxt,QuestionActivity.class);

            generateNotification(ctxt,extras.getString("message"),"New message"  );           
        }
        catch ( Exception e )
        {
        }
      }

更新： @H_419_11@给Eran以JSON为荣,我只想详细说明.

您可以使用数据键添加其他参数：

{
   "registration_ids" : ["APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx..."],"data": {
       "stuff": "100","more": "abc"
   },}

然后使用intent.getExtras().getString(“stuff”)以相同的方式访问.

全是here.

然后在你的generateNotifcation()中：

private static void generateNotification(Context context,String messagE) {
    notificationmanager notificationmanager = (notificationmanager)
        context.getSystemservice(Context.NOTIFICATION_serviCE);
    Notification notification = new Notification(R.drawable.ic_launcher,message,when);
    String title = "...";


    //get id from json here and decide which activity to go to...
    Intent notificationIntent = new Intent(context,someClass.class);


    notificationIntent.putExtra("message",messagE);
    PendingIntent intent = PendingIntent.getActivity(context,notificationIntent,PendingIntent.FLAG_updatE_CURRENT);
    notification.setLatestEvenTinfo(context,title,intent);
    notification.defaults|=Notification.DEFAULT_VIBRATE;
    notificationmanager.notify(0,notification);
}
