推荐答案

下面是你的想法如何实现这一任务：

Here is the idea how you can achieve this task:

首先，你需要一个Runnable（），当你的超时时间（如10秒）时，将运行。下面是可运行（）：

Firstly you need a Runnable(), which will be Run when your timeout(e.g. 10 sec) occurs. Below is the Runnable():

private Runnable DoOnTimeOut = new Runnable() 
{
    public void run() 
    {
        // Do something Here
    }
}

现在，在你的活动，你可以调用postDelayed为DoOnTimeOut：

Now, in your activity, you can call postDelayed for the DoOnTimeOut:

Handler hl_timeout = new Handler();

@Override
public void onCreate(Bundle b)
{
   hl_timeout.postDelayed(DoOnTimeOut, 10000); // The DoOnTimOut will be triggered after 10sec
}

现在，最重要的是，当你看到用户的交互，要取消呼叫DoOnTimeOut，然后重新设定的要求，持续10秒。这是你的活动的用户交互的覆盖方式：<​​/ P>

Now, most important part is that when you see user interaction, you want to cancel the call to DoOnTimeOut and then again set the call for next 10 sec. Here is the Override method of your Activity for User Interaction:

@Override
public void onUserInteraction()
{
    super.onUserInteraction();
    //Remove any previous callback
    hl_timeout.removeCallbacks(DoOnTimeOut);
    hl_timeout.postDelayed(DoOnTimeOut, 10000);
}

我希望这将是对你有所帮助。

I hope it will be helpful for you.
