高仿微信对话列表滑动删除效果

转载：http://blog.csdn.net/singwhatiwanna/article/details/17515543

前言

用过微信的都知道，微信对话列表滑动删除效果是很不错的，这个效果我们也可以有。思路其实很简单，弄个ListView，然后里面的每个item做成一个可以滑动的自定义控件即可。由于ListView是上下滑动而item是左右滑动，因此会有滑动冲突，也许你需要了解下android中点击事件的派发流程，请参考Android源码分析-点击事件派发机制。我的解决思路是这样的：重写ListView的onInterceptTouchEvent方法，在move的时候做判断，如果是左右滑动就返回false，否则返回true；重写SlideView（即自定义item控件）的onTouchEvent方法来处理滑动。整个思路没有问题，滑动冲突也解决了，可是ListView无法得到焦点了，也就是ListView无法处理点击事件了。让我们回想下问题出在哪里：我的理解是这样的，上述处理滑动本身没有问题，但是有一个副作用，就是会让外层View失去焦点且无法处理点击事件。常见的滑动冲突场景，比如launcher内部嵌入ListView却是没有问题的，因为这个时候launcher不需要获得焦点，需要获得焦点的是内部的ListView。因此，上述处理方式对于外部需要获得焦点的情况（比如外部是ListView）就不太适合了。于是我就和ttdevs探讨，发现他采用了另外一种思路，我从来没有想过还可以这样玩。下面介绍他的思路。

新的思路

不考虑那么复杂，不采用主流玩法，所有的事件均由外层的ListView做拦截，同时把事件传递给SlideView做滑动，这种实现的确可以达到效果，而且代码很简单，根本不需要处理什么复杂的滑动冲突。

代码分析

先看SlideView是如何实现的

看layout xml：

上述xml文件中，所有的view都会被放在view_content中，而holder是放置诸如删除按钮之类的东西，我们的SlideView会加载这个布局。

再看SlideView.java：

上述代码做了很详细的说明，这就是滑动控件的完整代码，大家要明白的是：你所添加的view都是加在SlideView的子View : view_content中的，而不是直接加在SlideView中，只有这样我们才方便做滑动效果。

接着看ListView的代码：核心就是下面这一个方法，将点击事件发送给SlideView处理。
