如何延缓执行的android [英] How to delay execution android

问题描述

我建立一个机器人棋盘游戏为特色的AI。人工智能得到了转弯，必须调用一系列后，它的帖子无效到我的自定义视图更新的动作。

I am building an android board game which features AI. The AI gets a turn and has to invoke a series of actions after which it posts invalidate to my custom view to update.

我需要让用户获取看到AI有轮到它，而不是它通过闪烁来减缓这些行动。

I need to slow down these actions so the user gets to see the AI having its turn rather than it flashing by.

我已经试过这些方针的东西

I have tried something along these lines

    try {
        doFirstThing();
        Thread.sleep(500)
        //post invalidate

        doNextThing();
        Thread.sleep(1000)
        //post invalidate
     }
     catch (Exception e) {
     }

然而，这是具有绝对没有影响。也这是在一个单独的线程中运行，如果这不明显。

However this is having absolutely no effect. Also this is running in a separate thread if this wasn't obvious.

请告诉我我最好的选择我看着处理，但他们并不需要正确的，因为我需要执行一系列任务的顺序，每次更新视图。

Whats my best option I've looked at handler but they don't need right as i need to execute a series of tasks in sequence updating the view each time.

推荐答案

使用处理程序，这是一个好主意，如果你是从UI线程执行...

Using a Handler, which is a good idea if you are executing from a UI thread...

    final Handler h = new Handler();

    final Runnable r2 = new Runnable() {

        @Override
        public void run() {
            // do second thing
        }
    };

    Runnable r1 = new Runnable() {

        @Override
        public void run() {
            // do first thing
            h.postDelayed(r2, 10000); // 10 second delay
        }
    };

    h.postDelayed(r1, 5000); // 5 second delay
