如果您要延迟一些code，你应该将它张贴在延迟时间的处理程序。
这样的处理将等待指定的时间，然后执行给定的可运行。

If you want to delay some code, you should post it in a handler with a delay time. This way the handler will wait the given time and then execute the given runnable.

    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            cpuPlay();
        }
    }, TIME_TO_WAIT_IN_MS);
