我想要在通知发出后显示activity而不点击通知Activity必须打开。我正在使用FCM进行通知发送。如何在没有点击通知的情况下显示活动

如何在不点击通知的情况下打开Activity？

我使用这一点，但它不会打开活动：

public class MyFirebaseMessagingService extends FirebaseMessagingService { 
private static final String TAG = "MyFirebaseMsgService"; 
String messageContent = ""; 
@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 
    // TODO(developer): Handle FCM messages here. 
    messageContent = remoteMessage.getData().get("message"); 
    showNotification(remoteMessage.getData().get("message")); 
    postToastMessage(remoteMessage.getData().get("message")); 
    Log.d(TAG, "From: " + remoteMessage.getFrom()); 
} 
public void postToastMessage(final String message) { 
    Handler handler = new Handler(Looper.getMainLooper()); 
    handler.post(new Runnable() { 
     @Override 
     public void run() { 
      Toast.makeText(getApplicationContext(), message +" received", Toast.LENGTH_LONG).show(); 
      Intent newIntent = new Intent(MyFirebaseMessagingService.this, CallActivity.class); 
      newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      startActivity(newIntent); 
     } 
    }); 
} 
private void showNotification(String message) { 
    Intent i = new Intent(this, CallActivity.class); 
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT); 
    NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(this) 
      .setAutoCancel(true) 
      .setContentTitle(" Test") 
      .setContentText(message) 
      .setSmallIcon(R.drawable.ic_launcher) 
      .setContentIntent(pendingIntent); 
    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
    manager.notify(0,builder.build()); 
} 
}

我收到此错误

FA: Discarding data. Failed to send event to service

回答：

请在你的代码延伸AppComatActivity和所有其他活动延伸BaseActivity基地活动，在节目通知内广播你的意图与新的活动，并在基地活动接收器，在该接收器内，你可以打开你的活动

更多象我可以显示如何为这个代码，

感谢

试试这个， 可能是有帮助的你，

添加在onMessageReceived（）这段代码方法，

在NotificationActivity.class 

if (getIntent().getBooleanExtra("isNotification", false)) { 
     message = getIntent().getStringExtra("message"); 
     txt_message.setText(message); 
    }

我简单的GET消息3210

添加此，

@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 
    Log.e(TAG, "From: " + remoteMessage.getFrom()); 
    Log.e(TAG, "onMessage receiveddd: " + remoteMessage.getData()); 
    // Log.e(TAG, "onMessage notification: " + remoteMessage.getNotification().getBody()); 
    // Check if message contains a data payload. 
    if (remoteMessage.getData().size() > 0) { 
     Log.e("notification background", String.valueOf(remoteMessage.getData())); 
     Log.d(TAG, "Message data payload: " + remoteMessage.getData()); 
     Map<String, String> data = remoteMessage.getData(); 
     String deviceID = data.get("DeviceID"); 
     String message = data.get("Message"); 
     Log.e("value11111111", deviceID); 
     Log.e("value222222222", message); 
     Intent intent = new Intent(MyFirebaseMessagingService.this, NotificationActivity.class); 
     intent.putExtra("isNotification", true); 
     // intent.putExtra("title", value1); 
     intent.putExtra("message", message); 
     intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     startActivity(intent); 
     // sendNotification("message received"); 
    } 
}

比邮差， 发送该请求

{ 
"data":{ 
"DeviceID":"",// pass here your DeviceID 
"Message":"hiiii" // pass here your message 
}, 
"to":""// pass here ypur tocken 
    }
