延时方式整理

延时的几种方式

Thread.sleep(100);//需要捕获异常
SystemClock.sleep(200);//不需要处理异常

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

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

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