FCM如何顯示通知中的數據點擊另一個活動

我有一個接收FCM通知的應用程序，我想在另一個活動中顯示通知和數據有效載荷的內容，我的挑戰是當我點擊通知時，它指示我慾望的活動，但我沒有得到顯示的信息。FCM如何顯示通知中的數據點擊另一個活動

請幫幫忙，下面是我的代碼

MyFirebaseMessagingService 
public class MyFirebaseMessagingService extends FirebaseMessagingService { 

    private static final String TAG = "MyFirebaseMsgService"; 

    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     Map<String, String> data = remoteMessage.getData(); 

     //you can get your text message here. 
     if (remoteMessage.getData().size() > 0) { 
      Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString()); 

      try { 
       String storedData = remoteMessage.getData().toString(); 
       // JSONObject json = new JSONObject(storedData); 

       JSONArray arr = new JSONArray(storedData); 
       JSONObject jObj = arr.getJSONObject(0); 
       String title = jObj.getString("title"); 
       String message = jObj.getString("body"); 
       sendPushNotification(jObj); 

       final String MY_PREFS_NAME = "MyFCMFile"; 
       SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit(); 
       editor.putString("Title", title); 
       editor.putString("Message", message); 
       editor.apply(); 

      } catch (Exception e) { 
       Log.e(TAG, "Exception: " + e.getMessage()); 
      } 
     } 
     else { 

      String title = remoteMessage.getNotification().getTitle(); 
      String message = remoteMessage.getNotification().getBody(); 
      String click_action = remoteMessage.getNotification().getClickAction(); 
      Intent intent = new Intent(click_action); 
      intent.addFlags(intent.FLAG_ACTIVITY_CLEAR_TOP); 
      PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT); 
      NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this); 
      notificationBuilder.setContentTitle(title); 
      notificationBuilder.setContentText(message); 
      notificationBuilder.setSmallIcon(R.mipmap.ic_launcher); 
      notificationBuilder.setAutoCancel(true); 
      notificationBuilder.setContentIntent(pendingIntent); 

      final String MY_PREFS_NAME = "MyFCMFile"; 
      SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit(); 
      editor.putString("Title", title); 
      editor.putString("Message", message); 
      editor.apply(); 

      NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
      notificationManager.notify(0, notificationBuilder.build()); 


     } 
    } 

    //this method will display the notification 
    //We are passing the JSONObject that is received from 
    //firebase cloud messaging 
    private void sendPushNotification(JSONObject json) { 
     //optionally we can display the json into log 
     Log.e(TAG, "Notification JSON " + json.toString()); 
     try { 
      //getting the json data 
      JSONObject data = json.getJSONObject("data"); 

      //parsing json data 
      String title = data.getString("title"); 
      String message = data.getString("message"); 
      String imageUrl = data.getString("image"); 

      final String MY_PREFS_NAME = "MyFCMFile"; 

      SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit(); 
      editor.putString("Title", title); 
      editor.putString("Message", message); 
      editor.apply(); 

      //creating MyNotificationManager object 
      MyNotificationManager mNotificationManager = new MyNotificationManager(getApplicationContext()); 
      // CREATE CLICK ACTION 

      //creating an intent for the notification 

      Intent intent = new Intent(getApplicationContext(), Notifications.class); 

      //if there is no image 
      if (imageUrl.equals("null")) { 
       //displaying small notification 
       mNotificationManager.showSmallNotification(title, message, intent); 
      } else { 
       //if there is an image 
       //displaying a big notification 
       mNotificationManager.showBigNotification(title, message, imageUrl, intent); 
      } 
     } catch (JSONException e) { 
      Log.e(TAG, "Json Exception: " + e.getMessage()); 
     } catch (Exception e) { 
      Log.e(TAG, "Exception: " + e.getMessage()); 
     } 
    } 
}

根據FCM文檔，看起來你做錯了。

onMessageReceived()只有在應用程序已經在前臺運行時纔會被調用。否則，Android將顯示通知（使用「通知」字典的屬性），並使用getClickAction()值打開所需的Activity，而無需編寫任何代碼。

而且你可以通過你的啓動器活動的意圖的額外獲得「數據」有效載荷。

即在Notifications類：

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    Bundle extras = getIntent().getExtras(); // you should find the data here 
    ... 
}

下面是我工作：

在我的第二個Activity類（點擊通知時應當打開的一個），我把：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_display_message); 

    TextView text = (TextView) findViewById(R.id.data2); 
    if (text != null) { 
     Bundle extras = getIntent().getExtras(); 
     StringBuilder keys = new StringBuilder(); 
     if (extras != null) { 
      for (String key : extras.keySet()) 
       keys.append(key + " = " + extras.getString(key) + "\n "); 
     } 
     text.setText("extras on second activity: " + keys.toString()); 
    } 
}

我得到了以下輸出：

extras on second activity: google.sent_time = null 
msg - some value (this is a key/value pair I included in the "data" dictionary) 
uri - some value (this is a key/value pair I included in the "data" dictionary) 
from - <the sender id> 
google.message_id - <the message id returned in the receipt of the HTTP response> 
collapse_key - com.package.fcmdemo (default value)

正如您所看到的，我的（自定義）「數據」字典的屬性全部傳遞給活動。「通知」字典的屬性沒有通過，但我假設這是故意的（因爲它們已經用於顯示我點擊的通知來打開活動）。

沒有顯示，我得到了相同的結果，都一樣謝謝 – LaideLawal
