在GCMBaseIntentService中顯示祝酒

Question

我在嘗試實現推送通知客戶端。我想在onMessage（Context arg0，Intent arg1）函數中顯示Toast。

，這是我的代碼：

public class GCMIntentService extends GCMBaseIntentService { 
static Context c; 
@SuppressWarnings("hiding") 
private static final String TAG = "GCMIntentService"; 

public GCMIntentService() { 
    super("717816998404"); 
    c = this.getBaseContext(); 
} 

/** 
* Issues a notification to inform the user that server has sent a message. 
*/ 

@Override 
protected void onError(Context arg0, String arg1) { 
    // TODO Auto-generated method stub 

} 

@Override 
protected void onMessage(Context arg0, Intent arg1) { 
    Log.d("GCM", "RECIEVED A MESSAGE"); 
    Log.d("GCM", "RECIEVED A MESSAGE"); 
    Log.d("GCM", "RECIEVED A MESSAGE"); 
    Log.d("GCM", "RECIEVED A MESSAGE"); 
    Log.d("GCM", "RECIEVED A MESSAGE"); 
    Log.d("GCM", "RECIEVED A MESSAGE"); 
    Log.d("GCM", "RECIEVED A MESSAGE"); 
    String str =arg1.getExtras().getString("PVAL"); 

    Log.i("PVAL",str); 
    // I want to display a toast here 

} 

@Override 
protected void onRegistered(Context arg0, String arg1) { 
    // TODO Auto-generated method stub 
    Log.i("TEST", arg1); 
    Log.e("TEST", arg1); 

} 

@Override 
protected void onUnregistered(Context arg0, String arg1) { 
    // TODO Auto-generated method stub 

} 

}

我想知道如何顯示接收到的消息，我想dispaly舉杯檢查消息。

Answer 1

試試這個：

Handler h = new Handler(Looper.getMainLooper()); 
     h.post(new Runnable(){ 

      public void run() { 
       // TODO Auto-generated method stub 
      Toast.makeText(arg0, arg1.getStringExtra("message"), Toast.LENGTH_LONG).show(); 
    }   
     }); 

Answer 2

如何在onMessage方法中添加toast創建？像這樣：

@Override 
protected void onMessage(Context arg0, Intent arg1) { 
    String str = arg1.getExtras().getString("PVAL"); 
    Toast.makeText(arg0, str, Toast.LENGTH_LONG).show(); 
} 

如果這不起作用，請按照GCM庫中捆綁的Demo示例進行操作。演示示例在主要活動中使用BroadcastReceiver，接收者在GCM傳入消息上顯示對話消息。您可以將對話框顯示改爲吐司顯示。
