计时线程Runnable和Handler的结合

利用Runnable和Handler，来创建计时线程

private double recodeTime = 0;// 用于计时
private double econdTime = 0;// 用于计时

private boolean flag=true;

private Thread thread;// 计时线程

private Runnable menuTimeTask = new Runnable() {
        public void run() {
            while (flag) {
                try {
                    Thread.sleep(200);
                    recodeTime += 0.2;
                    econdTime += 0.2;
                    handler.sendEmptyMessage(1);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                    return;
                }
            }
        }

        Handler handler = new Handler() {
            public void handleMessage(Message msg) {
                switch (msg.what) {
                case 1:if (recodeTime > 8) {//计时8秒后进行事务逻辑
//                  do what you like
                            recodeTime=0;
                        }if (econdTime > 16) {
                            econdTime=0;
                            recodeTime=0;
                        }
                    break;
                }
            }
        };
    };
