通知をクリックした後に特定のアクティビティを開くにはどうすればよいですか？

Question

通知をクリックした後、ShowNotificationActivityをリダイレクトします。しかし、私がそれをクリックすると、アプリは最初から始まります。この問題を解決するには？ここにコードがあります。別のクラスにおいて

public class MyFirebaseMessagingService extends FirebaseMessagingService { 

    private static final String TAG = MyFirebaseMessagingService.class.getSimpleName(); 

    private NotificationUtils notificationUtils; 
    NotificationDatabaseHandler notificationDatabaseHandler; 

    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
    Log.e(TAG, "From: " + remoteMessage.getFrom()); 

    if (remoteMessage == null) 
     return; 

    // Check if message contains a notification payload. 
    if (remoteMessage.getNotification() != null) { 
     Log.e(TAG, "Notification Body: " + remoteMessage.getNotification().getBody()); 
     handleNotification(remoteMessage.getNotification().getBody()); 
    } 

    // Check if message contains a data payload. 
    if (remoteMessage.getData().size() > 0) { 
     Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString()); 

     try { 
      JSONObject json = new JSONObject(remoteMessage.getData().toString()); 
      handleDataMessage(json); 
     } catch (Exception e) { 
      Log.e(TAG, "Exception: " + e.getMessage()); 
     } 
    } 
    } 

    private void handleNotification(String message) { 
    if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) { 
     // app is in foreground, broadcast the push message 
     Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION); 
     pushNotification.putExtra("message", message); 
     LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification); 

     // play notification sound 
     NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext()); 
     notificationUtils.playNotificationSound(); 
    }else{ 
     // If the app is in background, firebase itself handles the notification 
    } 
    } 

    private void handleDataMessage(JSONObject json) { 
    Log.e(TAG, "push json: " + json.toString()); 

    try { 
     JSONObject data = json.getJSONObject("data"); 

     String title = data.getString("title"); 
     String message = data.getString("message"); 

     boolean isBackground = data.getBoolean("is_background"); 
     String imageUrl = data.getString("image"); 
     String timestamp = data.getString("timestamp"); 
     JSONObject payload = data.getJSONObject("payload"); 

     Log.e(TAG, "title: " + title); 
     Log.e("yes", "message: " + message); 
     Log.e(TAG, "isBackground: " + isBackground); 
     Log.e(TAG, "payload: " + payload.toString()); 
     Log.e(TAG, "imageUrl: " + imageUrl); 
     Log.e(TAG, "timestamp: " + timestamp); 

     if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) { 
      // app is in foreground, broadcast the push message 
      Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION); 
      pushNotification.putExtra("message", message); 
      LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification); 

      // play notification sound 
      NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext()); 
      notificationUtils.playNotificationSound(); 

     } else { 
      // app is in background, show the notification in notification tray 
      Intent resultIntent = new Intent(getApplicationContext(), ShowNotificationActivity.class); 
      resultIntent.putExtra("message", message); 


      // check for image attachment 
      if (TextUtils.isEmpty(imageUrl)) { 
       showNotificationMessage(getApplicationContext(), title, message, timestamp, resultIntent); 
      } else { 
       // image is present, show notification with image 
       showNotificationMessageWithBigImage(getApplicationContext(), title, message, timestamp, resultIntent, imageUrl); 
      } 
     } 
    } catch (JSONException e) { 
     Log.e(TAG, "Json Exception: " + e.getMessage()); 
    } catch (Exception e) { 
     Log.e(TAG, "Exception: " + e.getMessage()); 
    } 
    } 

    /** 
    * Showing notification with text only 
    */ 
    private void showNotificationMessage(Context context, String title, String message, String timeStamp, Intent intent) { 
    notificationUtils = new NotificationUtils(context); 
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); 
    notificationUtils.showNotificationMessage(title, message, timeStamp, intent); 
    } 

    /** 
    * Showing notification with text and image 
    */ 
    private void showNotificationMessageWithBigImage(Context context, String title, String message, String timeStamp, Intent intent, String imageUrl) { 
    notificationUtils = new NotificationUtils(context); 
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); 
    notificationUtils.showNotificationMessage(title, message, timeStamp, intent, imageUrl); 
    } 
} 

.........................

public void showNotificationMessage(String title, String message, String timeStamp, Intent intent) { 
    showNotificationMessage(title, message, timeStamp, intent, null); 
} 

public void showNotificationMessage(final String title, final String message, final String timeStamp, Intent intent, String imageUrl) { 
    // Check for empty push message 
    if (TextUtils.isEmpty(message)) 
     return; 

    // notification icon 
    final int icon = R.drawable.ic_notification; 

    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); 
    final PendingIntent resultPendingIntent = 
      PendingIntent.getActivity(
        mContext, 
        0, 
        intent, 
        PendingIntent.FLAG_CANCEL_CURRENT 
      ); 
} 

Answer 1

はスラジュねえ、それは簡単です

追加するだけで

resultIntent = (getApplicationContext(), SecondActivity.class); 

通知のクリックでコールしたい第2のアクティビティです。

とされています。

Answer 2

次の通知の使用を送る：

NotificationManager mNotificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE); 
     Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
     NotificationCompat.Builder mBuilder = 
       new NotificationCompat.Builder(mContext) 
       .....; 


Intent activityIntent = new Intent(mContext, ShowNotificationActivity.class); 
      activityIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 

PendingIntent contentIntent = PendingIntent.getActivity(mContext, 0, activityIntent, PendingIntent.FLAG_ONE_SHOT); 
     mBuilder.setContentIntent(contentIntent); 

     mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
