单击Android通知时打开对话活动

Question

**我在聊天中得知，当应用程序在后台运行时，它可以完美地接收到通知，但是当我单击时，它将打开主菜单。

也许清单上有事要做。**

我希望打开发送消息的用户的对话

MyFirebaseMessaging.java

public class MyFirebaseMessaging extends FirebaseMessagingService {
    private static final String TAG = "FirebaseIntent";
    @Override
    public void onNewToken(@NonNull String s) {
        super.onNewToken(s);

        FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
        String refreshToken = FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken();

        if (firebaseUser != null) {
            updateToken(refreshToken);
        }
    }

    private void updateToken(String refreshToken) {
        FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();

        DatabaseReference reference = FirebaseDatabase.getInstance().getReference("Tokens");
        Token token = new Token(refreshToken);
        reference.child(firebaseUser.getUid()).setValue(token);
    }

    @Override
    public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
       

        Map<String, String> data_notify = remoteMessage.getData();

        //String sented=remoteMessage.getData().get("sented");
        user = remoteMessage.getData().get("user");
        Log.d(TAG, "Message data payload: " + user);

        SharedPreferences preferences  = getSharedPreferences("PREFS", MODE_PRIVATE);
        String currentUser = preferences.getString("currentuser", "none");

        FirebaseUser firebaseUser= FirebaseAuth.getInstance().getCurrentUser();

        //String click_action = remoteMessage.getNotification().getClickAction();

        if (firebaseUser != null && data_notify.size() > 0)
        {
            if (!currentUser.equals(user))
            {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
                {
                    sendOreoNotification(remoteMessage);
                } else {
                    sendNotification(remoteMessage);
                }
            }
        }

    }


    @RequiresApi(api = Build.VERSION_CODES.O)
    private void sendOreoNotification(RemoteMessage remoteMessage){
        String user = remoteMessage.getData().get("user");
        String icon = remoteMessage.getData().get("icon");
        String title = remoteMessage.getData().get("title");
        String body = remoteMessage.getData().get("body");

        RemoteMessage.Notification notification=remoteMessage.getNotification();
        int j = Integer.parseInt(user.replaceAll("[\\D]", ""));

        Intent intent = new Intent(this, Nuevo_mensaje_Activity.class);

        Bundle bundle=new Bundle();
        bundle.putString("userid", user);
        intent.putExtras(bundle);
        Log.d(TAG, "Message data payload: " + user);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent=PendingIntent.getActivity(this, j,intent,PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSound= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        OreoNotification oreoNotification = new OreoNotification(this);
        Notification.Builder builder = oreoNotification.getOreoNotification(title,body,pendingIntent,
                defaultSound,icon);
        int i=0;
        if(j>0){
            i=j;
        }
        oreoNotification.getManager().notify(i,builder.build());

    }

    private void sendNotification(RemoteMessage remoteMessage) {
        String user = remoteMessage.getData().get("user");
        String icon = remoteMessage.getData().get("icon");
        String title = remoteMessage.getData().get("title");
        String body = remoteMessage.getData().get("body");

        RemoteMessage.Notification notification=remoteMessage.getNotification();

        int j = Integer.parseInt(user.replaceAll("[\\D]", ""));

        Intent intent = new Intent(this, Nuevo_mensaje_Activity.class);
        Bundle bundle=new Bundle();
        bundle.putString("userid", user);
        intent.putExtras(bundle);

        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent=PendingIntent.getActivity(this,j,intent,PendingIntent.FLAG_ONE_SHOT);

        Log.d(TAG,"NEW_INTENT: "+user);

        Uri defaultSound= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(Integer.parseInt(icon))
                .setContentTitle(title)
                .setContentText(body)
                .setAutoCancel(true)
                .setSound(defaultSound)
                .setContentIntent(pendingIntent);
        NotificationManager noti=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

        int i=0;
        if(j>0){
            i=j;
        }
        noti.notify(i,builder.build());




    }
}

我有另一项活动，发送了第一条消息，可能是造成问题的原因

ChatActivity.java

private void sendNotification(String receiver, final String username, final String message)
    {
        DatabaseReference tokens=FirebaseDatabase.getInstance().getReference("Tokens");
        Query query=tokens.orderByKey().equalTo(receiver);
        query.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                for(DataSnapshot snapshot: dataSnapshot.getChildren()){
                    Token token=snapshot.getValue(Token.class);
                    Data data =new Data(fuser.getUid(),R.drawable.logo_peque,username+": "+message, "Nuevo Mensaje",messageReceicverID);

                    Sender sender=new Sender(data, token.getToken());
                    apiService.sendNotification(sender)
                            .enqueue(new Callback<MyResponse>() {
                                @Override
                                public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
                                    if(response.code()==200){
                                        if(response.body().success!=1){
                                            Toast.makeText(ChatActivity.this, "!Fallo¡", Toast.LENGTH_SHORT).show();
                                        }
                                    }
                                }

                                @Override
                                public void onFailure(Call<MyResponse> call, Throwable t) {

                                }
                            });

                }

            }

            @Override
            public void onCancelled(@NonNull DatabaseError error) {

            }
        });

    }

没有答案可以帮助我，我已经尝试了所有方法，希望有人可以帮助我。
