Android 一个view如何同时响应onTouch和onClick事件

一个view如何同时响应onTouch和onClick事件,这种情况很多,但是在网上搜了很长时间,大多数都是讲解如何区分onTouchEvent和onClick,onLongClick的调用顺序和流程.但是都没有讲到如何让onTouch事件和onClick事件共存.也就是说一个控件既能响应点击事件又能响应触摸事件.

首先声明,此博文参考的文章链接https://technicalsearch.iteye.com/blog/1972470   感谢前辈的智慧结晶.

值得说明的是解决的思路：在touch事件的onMove中判断手指的移动距离,当移动通过勾股定理算出<15px时,就把此事件当做是点击事件,当算出移动距离大于等于15px时就当做触摸事件处理

直接贴出代码,需要的朋友复制粘贴就可使用.
