推荐答案

例如，你可以使用一个处理程序并调用其.removeCallbacks（）和.postDelayed（）方法，每次用户与对话框交互。

You could for example use a Handler and call its .removeCallbacks() and .postDelayed() method everytime the user interacts with the dialog.

当一个互动，.removeCallbacks（）方法将取消.postDelayed（）的执行，并紧接着，U启动一个新的Runnable与.postDelayed（）

Upon an interaction, the .removeCallbacks() method will cancel the execution of .postDelayed(), and right after that, u start a new Runnable with .postDelayed()

这里面运行的，你可以关闭对话框。

Inside this Runnable, you could close the dialog.

    // a dialog
    final Dialog dialog = new Dialog(getApplicationContext());

    // the code inside run() will be executed if .postDelayed() reaches its delay time
    final Runnable runnable = new Runnable() {

        @Override
        public void run() {
            dialog.dismiss(); // hide dialog
        }
    };

    Button interaction = (Button) findViewById(R.id.bottom);

    final Handler h = new Handler();

            // pressing the button is an "interaction" for example
    interaction.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {


            h.removeCallbacks(runnable); // cancel the running action (the hiding process)
            h.postDelayed(runnable, 5000); // start a new hiding process that will trigger after 5 seconds
        }
    });

有关跟踪用户的交互，可以使用：

For tracking user interaction, you could use:

@Override
public void onUserInteraction(){
    h.removeCallbacks(runnable); // cancel the running action (the hiding process)
    h.postDelayed(runnable, 5000); // start a new hiding process that will trigger after 5 seconds
}

其中在您的活动是可用的。
