如何检测在几秒钟后视图无接触？ [英] How to detect no touch on a view after some seconds?

问题描述

我有一个小视图（称之为用户对象）的重叠背景视图（称之为地图）。我可以拖动用户对象。

I have a small view (call it "user-object") which overlap the background view (call it map). I can drag the "user-object".

我要以用户为对象自动移动到中点（SCREEN_WIDTH / 2，SCREEN_HEIGHT / 2）几秒钟（比如4S）如果三是没有触摸/拖拽。之后

I want the "user-object" automatically move to "mid-point" (screen_width/2, screen_height/2) after some seconds (for instance 4s) if three is no touch/drag.

推荐答案

用一个例子处理程序

Handler mHandler;
public void useHandler() {
   mHandler = new Handler();
   mHandler.postDelayed(mRunnable, 1000);
  }

  private Runnable mRunnable = new Runnable() {

    @Override
    public void run() {
               // Perform this here 
               "user-object" automatically move to "mid-point" (screen_width/2, screen_height/2)
      mHandler.postDelayed(mRunnable, 1000);
    }

一拖/触摸事件被触发后，再次申请 handler.postDelayed（）。
