Android - 我怎样才能发送GCM推送通知，并指示要加载哪些活动？ [英] Android - how can I send a GCM push notification with instructions of which activity to load?

问题描述

我可以创建推送通知。但目前我只能让人们登陆主屏幕。

我如何将人员发送到特定的活动？是否也可以添加一些像item_id这样的参数，以便活动知道要加载哪些数据？

或者如果在某个地方有一个很好的教程，那会是很好。我无法真正看到通过Google搜索找到很多有用的信息。

在我的GCMIntentService中，我有这个方法：

  @Override 
 protected void onMessage（Context ctxt，Intent message）
 {
 Bundle extras = message.getExtras（）; 
 
尝试
 {
 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（例外e）
 {
} 
} 
  

但我不确定如何更改generateNotification以指示此人应该登陆的活动。
Thanks！

解决方案

更新：
让Eran信誉为JSON，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）。

全部是 $ b 然后在你的> generateNotifcation（）：

  private static void generateNotification（Context context，String message）{
 NotificationManager notificationManager =（NotificationManager）
 context.getSystemService（Context.NOTIFICATION_SERVICE）; 
通知通知=新通知（R.drawable.ic_launcher，message，when）; 
 String title =...; 
 
 
 //从这里获取json的id，并决定要去哪个活动... 
 Intent notificationIntent = new Intent（context，someClass.class）; 
 
 
 notificationIntent.putExtra（message，message）; 
 PendingIntent intent = PendingIntent.getActivity（context，0，notificationIntent，PendingIntent.FLAG_UPDATE_CURRENT）; 
 notification.setLatestEventInfo（context，title，message，intent）; 
 notification.defaults | = Notification.DEFAULT_VIBRATE; 
 notificationManager.notify（0，notification）; 
} 
  

I am able to create push notifications. But currently I am just able to make people land on the home screen.

How can I send people to a specific Activity? And is it possible to also put add some parameter like item_id so the activity knows what data to load?

Or if there is a good tutorial for this somewhere, that would be great as well. I can't really seem to find much good info on this by googling.

In my GCMIntentService I have this method:

      @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 )
        {
        }
      }

But I am not sure how to change the generateNotification to also signal what Activity the person should land on. Thanks!

解决方案

UPDATE: Give Eran credit for the JSON, I just want to elaborate.

You can add other parameters with the data key:

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

Then access the same way using intent.getExtras().getString("stuff").

It is all here.

Then in your generateNotifcation():

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, 0, notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.defaults|=Notification.DEFAULT_VIBRATE;
    notificationManager.notify(0, notification);
}
