Handler的postDelayed(Runnable, long)

handler.postDelayed(myRunnable,1000)是为了轮播图片，每隔1000ms后执行一次run方法，实现轮播
实例如下：

public  void    MesageColse(){

      Runnable runnable=newRunnable(){

        @Override

        public void  run(){

           message_show.setText("");

        }

      };

      Handler myHandler=newHandler();

      myHandler.postDelayed(runnable,);

}
