putExtra 使用挂起的意图不起作用 [英] putExtra using pending intent not working
问题描述
我在我的 GCMIntentservice 中编写了一个代码,用于向许多用户发送推送通知.我使用 NotificationManager 将在单击通知时调用 DescriptionActivity 类.我还将来自 GCMIntentService 的 event_id 发送到 DescriptionActivity
I have written a code in my GCMIntentservice that sends push notifications to many users. I use the NotificationManager that will call DescriptionActivity class when the notification is clicked. I also send the event_id form the GCMIntentService to the DescriptionActivity
protected void onMessage(Context ctx, Intent intent) {
message = intent.getStringExtra("message");
String tempmsg=message;
if(message.contains("You"))
{
String temparray[]=tempmsg.split("=");
event_id=temparray[1];
}
nm= (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
intent = new Intent(this, DescriptionActivity.class);
Log.i("the event id in the service is",event_id+"");
intent.putExtra("event_id", event_id);
intent.putExtra("gcmevent",true);
PendingIntent pi = PendingIntent.getActivity(this,0, intent, 0);
String title="Event Notifier";
Notification n = new Notification(R.drawable.defaultimage,message,System.currentTimeMillis());
n.setLatestEventInfo(this, title, message, pi);
n.defaults= Notification.DEFAULT_ALL;
nm.notify(uniqueID,n);
sendGCMIntent(ctx, message);
}
这里我在上述方法中得到的 event_id 是正确的,即我总是得到更新的.但是在下面的代码中(DescriptionActivity.java):
Here the event_id that I'm getting in the above method is correct i.e I always get the updated one. But in the code below (DescriptionActivity.java):
intent = getIntent();
final Bundle b = intent.getExtras();
event_id = Integer.parseInt(b.getString("event_id"));
此处的 event_id 始终为5".无论我在 GCMIntentService 类中放了什么Extra,我得到的 event_id 总是 5.有人可以指出问题吗?是因为未决的意图吗?如果是,那我该如何处理?
The event_id here is always "5". No matter what I putExtra in the GCMIntentService class,the event_id I get is always 5. Can somebody please point out the problem? Is is because of the pending intent? If yes, then how should I handle it?
推荐答案
PendingIntent
与您提供的第一个 Intent
重用,那是您的问题.
The PendingIntent
is reused with the first Intent
you provided, that's your problem.
为避免这种情况,请使用标志PendingIntent.FLAG_CANCEL_CURRENT
a> 当您调用 PendingIntent.getActivity()
以实际获得一个新的时:
To avoid this, use the flag PendingIntent.FLAG_CANCEL_CURRENT
when you call PendingIntent.getActivity()
to actually get a new one:
PendingIntent pi = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
或者,如果您只想更新附加内容,请使用标志PendingIntent.FLAG_UPDATE_CURRENT
Alternatively, if you just want to update the extras, use the flag PendingIntent.FLAG_UPDATE_CURRENT
