我正在尝试使用C2DM在我的Android手机上触发推送通知,并让用户点击通知并在应用中启动某项活动。我怎样才能传递这些信息?
目前我正在做以下事情:
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager
= (NotificationManager) getSystemService(ns);
int icon = R.drawable.notification23;
Notification notification = new Notification(icon, tickerText, when);
notification.flags |= Notification.FLAG_ONGOING_EVENT | Notification.FLAG_AUTO_CANCEL;
Context appContext = getApplicationContext();
Intent notificationIntent = new Intent(this, RequestDialogActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.putExtra(LocationHandler.KEY_ORIGINATOR, number);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.setLatestEventInfo(appContext, contentTitle, contentText, contentIntent);
final int id = 1;
mNotificationManager.notify(id, notification);
我正在尝试通过在notificationIntent上调用putExtra
来存储状态,但新活动始终具有null savedInstanceState Bundle。我如何传递信息?
答案 0 :(得分:1)
您在意图中设置的额外内容必须由getIntent().getExtras()
检索savedInsanceState
