viewpager 내에서 Thread 사용 질문 있습니다

Question

@Override
    public Object instantiateItem(ViewGroup container, int position) {
        View v =null;

        if (position == 0) {
            v = mInflater.inflate(R.layout.page1, null);
            high = (ImageView) v.findViewById(R.id.high);
         

    
          
            Thread thread1 = new Thread(new Runnable() {
                @Override
                public void run() {

                    handler.postAtTime(new Runnable() {
                        @Override
                        public void run() {
                            count = 0;

                            while (true) {

                                if (count == 0) {
                                    high.setImageResource(R.drawable.img1);
                                    try {
                                        Thread.sleep(500);
                                    } catch (InterruptedException e) {
                                        e.printStackTrace();
                                    }


                                } else if (count == 1) {
                                    high.setImageResource(R.drawable.img2);
                                    try {
                                        Thread.sleep(100);
                                    } catch (InterruptedException e) {
                                        e.printStackTrace();
                                    }

                                }

                                count++;
                                if (count == 2) {
                                    count = 0;
                                }
                            }


                        }
                    }, 100);


                }
            });


            thread1.start();



            container.addView(v);

 

 pagerAdapter  코드중 일부분 입니다(조금 불편하게 써져있는건 봐주세요 ㅠㅠ)

이렇게 뷰를 추가하고 이미지를 주기적으로 바꿔주려는데 position 0 만 가면 앱이 멈춰버립니다 ㅠㅠ

thread 쪽 에서 뭔가 걸리는거 같은데 멈추면서 로그도 아예안떠서 답답하네요 ㅠㅠ

고수님들 부탁합니다!!
