我的应用程序从GCM收到消息。
我已正确配置服务和广播接收器。然后，当消息即将发生时，我会显示通知。我有不同类型的消息的不同通知。运行正常。
好吧，现在我需要在收到新邮件时更新通知，例如Whatsapp。
例如，当Whatsapp从联系人收到一条消息时，显示短信，＆＃34; Hello world！＆＃34;但是当从同一个联系人那里收到另一个时，更改通知信息，显示＆＃34;两个新消息＆＃34;。如果收到来自其他联系人的消息，通知会在2个聊天中显示＆＃34; 3条消息＆＃34;等等。
我需要对两种类型的消息做同样的事情，但不是全部。然后，我需要知道哪些通知显示actionBar然后更新那些通知，而不是其他通知。我想为显示的所有通知创建一个bucle，分析它们并检查是否有任何人显示我的特定类型，之前创建新的。
如何从notificationManager或StatusActionBar获取信息以进行更改？如何检查Actionbar上显示的通知是否具有相同类型的通知？
感谢。
GCMIntentService.java
此服务分析＆＃34;额外＆＃34;来自GCM消息的值（notificationType）。制作一个切换案例并为通知中的节目撰写数据。
有一种显示通知的方法。我已经对showNotification方法发表了一些评论，以便了解我的需求。

要在应用收到PushNotification时更新视图，您需要LocalBroadCastManager
http://developer.android.com/reference/android/support/v4/content/LocalBroadcastManager.html
在Service＆＃34; GCMIntentService＆＃34;中，在onMessage方法中，你需要添加nextCode：
Intent intent = new Intent("Reload");
// You can also include some extra data.
intent.putExtra("message", "Reload");
LocalBroadcastManager.getInstance(getApplicationContext())
.sendBroadcast(intent);
这样就可以注册一个新的广播信息。
现在在更新课程中，您需要添加下一个： 在onCreate方法中：
LocalBroadcastManager.getInstance(getApplicationContext())
.registerReceiver(mMessageReceiver,
new IntentFilter("Reload"));
在您需要添加下一个方法之前：
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// Get extra data included in the Intent
String message = intent.getStringExtra("message");
if (message.equalsIgnoreCase("Reload")) {
//Actions...for reload a listView, TextView, etc...
}
}
};
重要的是添加onDestroy方法：
@Override
public void onDestroy() {
// Unregister since the activity is about to be closed.
LocalBroadcastManager.getInstance(getApplicationContext())
.unregisterReceiver(mMessageReceiver);
super.onDestroy();
}
.... PD：抱歉我的英文......
