OnTouch延迟（Android版） [英] OnTouch delay (Android)

问题描述

我有一个应用程序，我需要有在ImageButton的每个触摸后的延迟。

I have an app where I need to have a delay after each touch in an ImageButton.

我试过了Thread.sleep（）方法，但我不知道这是否是对付它的最好办法。

I tried the Thread.sleep() method, but I am not sure if this is the best way to deal with it.

你们有什么建议？

任何帮助AP preciatted！

Any help is appreciatted!

一件事：我要onTouch（）事件的内容被然后烧制我不想耽误X秒下一onTouch（）事件。这就像到prevent用户点击次数太多的按钮。

ONE MORE THING: I want the content of the onTouch() event to be fired THEN I want to delay "X" seconds the next onTouch() event. It's like to prevent the user to click too many times in the button.

推荐答案

由于所有的触摸事件是由UI线程处理，视频下载（）将阻止你的UI线程这是（我希望）你正在寻找没有什么。
我认为，要解决你的问题的最正确的方法是使用 postDelayed在的onClick 处理器（Runnable接口，长）接口它允许你开始延迟执行：

Since all touch events are handled by UI thread, Thread.sleep() will block your UI thread which is (I hope) not what you are looking for. I think the most correct way to solve your problem would be using postDelayed(Runnable, long) interface in your onClick handler which allows your to delay execution:

@Override
public void onClick(View v)
{
    postDelayed(new Runnable()
    {

        @Override
        public void run()
        {
            // do your stuff here
        }
    }, 10000); //10sec delay
}

更新：

如果您希望用户prevent点击太快了你的形象的看法，我强烈建议去与的onClick ，而不是 onTouch （除非有严重的原因是什么）

If you want user to prevent clicking too fast on your image view, I strongly recommend go with onClick rather than onTouch (unless there are serious reasons for that)

不过，请参阅code段这可能会帮助您：

However, please see the code snippet which might help you:

private boolean blocked = false;
private Handler handler = new Handler();

@Override
public boolean onTouchEvent(MotionEvent event)
{
    if (event.getAction() == MotionEvent.ACTION_DOWN)
    {
        if (!blocked)
        {
            blocked = true;
            handler.postDelayed(new Runnable()
            {
                @Override
                public void run()
                {
                    blocked = false;
                }
            }, 1000);
        } else
        {
            return false;
        }
    }
    return super.onTouchEvent(event);
}
