我想刷新listview.当我从不同的类中获取值时,我希望它将其更新为列表视图.我正在创建一个用于刷新列表的线程,但我得到一个异常:

Only the original thread that created a thread a view hierarchy can touch its views

如何进行？

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    final ThraedDemo objDemo = new ThraedDemo();
    Thread objThread = new Thread() {

        @Override
        public void run() {

            objDemo.firstMethod();
        }
    };
    objThread.start();
}


class ThraedDemo {

        private void firstMethod() {
            Thread objThread = new Thread() {

                @Override
                public void run() {
                    try {
                    ((ImageView)findViewById(R.id.ImageViewnumber)).setImageResource(nums[n]);

                        Thread.sleep(10000);
                        Log.v("Thread","1111111111111111sleep");
                    } catch (InterruptedException ex) {
                        System.out.println("interuped exception" + ex.getMessage());
                    }
                    secondMethod();
                }

                private void secondMethod() {
        Thread objThread = new Thread() {

            @Override
            public void run() {
                try …
