如何將GCM通知消息轉換爲android中的活動？

說明：我正在使用GCM向用戶發送通知。一切都已完成。我創建了一個服務器端編程，爲push_message創建一個休息，並完成所有事情。如何將GCM通知消息轉換爲android中的活動？

當我點擊通知時，此消息將打開到我的活動中。

我該如何在我的活動中打開我的消息？

這裏是我的GCMIntentService.java

請幫我解決掉。

你想打開點擊notificaiton所需活動的活動信息？ –

我覺得當你收到通知時，你會使用Localbroadcast接收器通知你的活動。我對嗎？ – Masum

是的，我認爲不確定。因爲我在android平臺更新鮮。我想要幫助 –

您發佈的代碼是IntentService，它使用GCM爲您的服務器註冊設備。

需要接收來自GCM消息的代碼是在這裏：

https://github.com/googlesamples/google-services/blob/master/android/gcm/app/src/main/java/gcm/play/android/samples/com/gcmquickstart/MyGcmListenerService.java#L43-L69

基本上，你需要創建自己的GcmListenerService。

不要忘記把你所有的服務和接收器放入AndroidManifest.xml。它應該看起來像這樣：

<!-- [START gcm_receiver] --> 
    <receiver 
     android:name="com.google.android.gms.gcm.GcmReceiver" 
     android:exported="true" 
     android:permission="com.google.android.c2dm.permission.SEND" > 
     <intent-filter> 
      <action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
      <category android:name="your package" /> 
     </intent-filter> 
    </receiver> 
    <!-- [END gcm_receiver] --> 

    <!-- [START gcm_listener] --> 
    <service 
     android:name=".MyGcmListenerService" 
     android:exported="false" > 
     <intent-filter> 
      <action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
     </intent-filter> 
    </service> 
    <!-- [END gcm_listener] --> 
    <!-- [START instanceId_listener] --> 
    <service 
     android:name=".MyInstanceIDListenerService" 
     android:exported="false"> 
     <intent-filter> 
      <action android:name="com.google.android.gms.iid.InstanceID"/> 
     </intent-filter> 
    </service> 
    <!-- [END instanceId_listener] --> 
    <service 
     android:name=".GcmIntentService" 
     android:exported="false"> 
    </service>

我在哪裏用這堂課？ –

爲此目的，我使用這個班級，我可以刪除我自己的班級嗎？ –

@MilanGajera從谷歌結帳這個例子：https：//github.com/googlesamples/google-services/tree/master/android/gcm – Mussa

您只需創建一個實現GcmListenerService的服務即可。

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"); 

    } 
}

當您收到需要廣播使用LocalBroadcastManager.getInstance(context).sendBroadcast(intent);
