ソケット io の runOnUiThread に問題があります。私はこのライブラリを使用しています。私はいくつかのイベントのリスナーを持っています。このイベントが発生したら、イメージを変更します。しかし、イベント画像を取得しても以前のままで、なぜそれが起こったのかわかりません。たぶん、誰かが私が間違っていることを助けたり説明したりします。前もって感謝します。これは私のコードです

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);
                }
            });
        }
    });
}

編集！

ソケットが正常に接続され、ログにオンライン/オフラインのメッセージが表示されます。また、コードをデバッグしてもエラーは表示されません。完全なコード

私はすでに私の問題を解決しました。理由はわかりませんが、runOnUiThread は正常に動作します。私は 3 日間、自分のコードの何が問題なのかを見つけようとしましたが、それよりもうまくいきました。それは完全に機能するコードです

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);
                    }
                });
            }
        });
    }

    }
