android - 套接字IO runOnUiThread不起作用

我在套接字io中遇到runOnUiThread的问题。我使用这个library。我有一些活动的听众。如果发生此事件，我将更改图像。但是当我得到事件图像时，像以前一样保持不变，我不明白为什么会这样。也许有人帮我解释我在做什么错。提前致谢。这是我的代码

private void online(){
    SocketService.getSocket().on("online", new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            activity.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Log.d("myLogs", "online");
                    onlineOffline.setImageResource(R.drawable.online);
                    callTo.setOnClickListener(ProfileList.this);
                    callToRegion.setOnClickListener(ProfileList.this);
                }
            });
        }
    });
}

private void offline() {
    SocketService.getSocket().on("offline", new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            activity.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Log.d("myLogs", "offline");
                    onlineOffline.setImageResource(R.drawable.offline);
                    callTo.setOnClickListener(ProfileList.this);
                    callToRegion.setOnClickListener(ProfileList.this);
                }
            });
        }
    });
}

编辑！

套接字已成功连接，我可以在日志中看到在线/离线消息。我也调试代码，不显示错误。完整代码

最佳答案

我已经解决了我的问题。我不知道为什么，但是runOnUiThread工作正常。我三天试图找到我的代码出了什么问题，然后才起作用。这是完全有效的代码

private void online(){
    if (SocketService.getSocket() != null)
        SocketService.getSocket().on("online", new Emitter.Listener() {
            @Override
            public void call(Object... args) {
                Log.d("myLogs", "online");
                activity.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Log.d("myLogs", "online");
                        onlineOffline.setImageResource(R.drawable.online);
                        callToRegion.setOnClickListener(ProfileList.this);
                        tvHelpDescription.setText("To call " + LoadDataFromDatabase.relativesData.get(pos).getFirstName() + " " +
                                LoadDataFromDatabase.relativesData.get(pos).getLastName() + " tap here");
                        CallPageFragment.arrow.setVisibility(View.VISIBLE);
                    }
                });
            }
        });
    else{
        Log.e("myLogs", "Socket is null");
    }
}

private void offline() {
    if(SocketService.getSocket() != null) {
        SocketService.getSocket().on("offline", new Emitter.Listener() {
            @Override
            public void call(Object... args) {
                activity.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Log.d("myLogs", "offline");
                        onlineOffline.setImageResource(R.drawable.offline);
                        callToRegion.setOnClickListener(null);
                        tvHelpDescription.setText("You can't call " + LoadDataFromDatabase.relativesData.get(pos).getFirstName() + " " +
                                LoadDataFromDatabase.relativesData.get(pos).getLastName() + " because she offline");
                        CallPageFragment.arrow.setVisibility(View.INVISIBLE);
                    }
                });
            }
        });
    }
    else{
        Log.e("myLogs", "Socket is null");
    }
}
