android更新UI的几种方法

1、handler.post(new Runnable{ runj(); });

        new Thread(){
            @Override
            public void run() {
                handler.post(new Runnable() {

                    @Override
                    public void run() {
                        textView.setText("update thread");
                    }
                });
            }
        }.start();

2、handler.postDelayed(myRunnable, 1000);

new Thread(){
        @Override
        public void run() {
            //在myRunnable更新UI
            handler.postDelayed(myRunnable, 1000);
        }
}.start();

3.handler.sendMessage(message);

            //新建一个message或者使用handler.obtainMessage();从当前缓存池中得到一个message。
        // Message message = new Message();
                Message message = handler.obtainMessage();
                Person person = new Person(23,"lhd");
                message.obj = person;

                message.sendToTarget();//使用message自身的方法发送
        // handler.sendMessage(message);//使用handler的sendMessage方法发送消息
        //在handler的handleMessage方法里更新UI

4.runOnUiThread(myRunnable);

        new Thread() {
            public void run() {
                //在myRunnable更新UI
                runOnUiThread(myRunnable);              
            };
        }.start();
