Android 多线程延迟(sleep)

new Thread(new Runnable(){     
        @Override  
            public void run(){     
                int count = 0;  
                while (true)  
                {  
                            count++;  
                            Log.e("Demo","count="+count);  
                    try {  
                Thread.sleep(500);  
                } catch (InterruptedException e) {  
                e.printStackTrace();  
                }  
                }  
            }     

        }).start();  

总结要点：
1、安卓内延迟只能用多线程实现
2、sleep外必须用try包裹
