下面是三种方法：

一、线程

new Thread(new Runnable(){
public void run(){
Thread.sleep(XXXX);
handler.sendMessage();----告诉主线程执行任务
}
}).start

二、延时器

TimerTask task = new TimerTask(){
public void run(){
//execute the task
}
};
Timer timer = new Timer();
timer.schedule(task, delay);

三、android消息处理

new Handler().postDelayed(new Runnable(){
public void run() {
//execute the task
}
}, delay);
