关于如何关闭android中service中新开启的线程问题？

1 stopBtn.setOnClickListener(new OnClickListener() {
2             
3             @Override
4             public void onClick(View v) {
5                 stopService(new Intent(MainActivity.this, MyServices.class));
6             }
7         });

    Thread     thread = new Thread(){
        @Override
        public void run() {
            super.run();
            while(true){
                Log.i("main", "hhhhhhhhhhhhhhhh");
                try {
                    sleep(1000);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    };

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        
    
        thread.start();
        return super.onStartCommand(intent, flags, startId);
    }
    
    @Override
    public void onDestroy() {
        super.onDestroy();
        thread.stop();
    }
