如何将GCM通知消息放入android中的活动？ [英] How to get GCM notification messages into an activity in android?
本文介绍了如何将GCM通知消息放入android中的活动？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用GCM向用户发送通知。一切都完成了。我创建了一个服务器端编程，为push_message创建一个休息，并完成了所有事情。
当我点击通知时，这些消息会打开到我的活动中。
如何在我的活动中打开我的消息？
这是我的GCMIntentService.java

请帮我解决。
解决方案
您只需创建一个实现GcmListenerService的服务即可。
public class EMSListenerService extends GcmListenerService {
private static final String TAG =ems_service;
@Override
public void onMessageReceived（String from，Bundle data）{
super.onMessageReceived（from，data）;
Display.log（TAG，EMS received）;
$ b $ / code $ / pre
当你收到你的信息时需要使用 LocalBroadcastManager.getInstance（context）.sendBroadcast（intent）;
广播到活动Explanation:
I am using GCM to send notification to the users.Everything is completed.I was created a server side programming to create a rest for push_message and all the thing is done.
When i click on the notification this messages are open into my activity.
How can i do to open my messages in my activity?
Here is my GCMIntentService.java
package com.angelnx.angelnx.mygcm.gcm;
import android.app.IntentService;
import android.content.Intent;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;

subscribeToTopic(topic);
break;

// if key is specified, register with GCM
registerGCM();

try {

// check for error
if (obj.getBoolean("error") == false) {
// broadcasting token sent to server
Intent registrationComplete = new Intent(Config.SENT_TOKEN_TO_SERVER);
LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(registrationComplete);
} else {
Toast.makeText(getApplicationContext(), "Unable to send gcm registration id to our sever. " + obj.getJSONObject("error").getString("message"), Toast.LENGTH_LONG).show();

Toast.makeText(getApplicationContext(), "Topic subscribe error. Topic: " + topic + ", error: " + e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
}
Please, help me to solve out.
解决方案 All you need to do is create one service that implements GcmListenerService.
public class EMSListenerService extends GcmListenerService {
private static final String TAG = "ems_service";
@Override
public void onMessageReceived(String from, Bundle data) {
super.onMessageReceived(from, data);
Display.log(TAG, "EMS received");
}
}
And when you receive the message you need to broadcast to the activity using LocalBroadcastManager.getInstance(context).sendBroadcast(intent);
