本文介绍了如何在Android中实现ListView的item水平滑动效果，包括自定义Item布局和ListView，详细讲解了自定义布局的设置、滑动事件处理及ListView的OnTouchEvent方法。通过这种方式，可以在滑动时展示额外的视图，如QQ聊天界面的删除按钮功能。

ListView的item水平滑动效果

---------------------------------------------------------------------

步骤：

1、自定义Item布局view
1、自定义布局中有至少两个view要显示：一个正常显示的布局contentView，一个隐藏起来的布局menuView
2、自定义布局中，设置两个布局的位置，通过onMeasure()，onLayout()两个方法设置
3、定义一个滑动处理方法，从父类获取到滑动事件，对滑动效果处理。
ACTION_DOWN：记录下滑动事件的初始位置。
ACTION_MOVE：根据滑动距离，显示view的位置
ACTION_UP：滑动结束后的操作
2、自定义ListView ，主要控制滑动事件的处理和分发
主要是onTouchEvent方法：
ACTION_DOWN：获取按下时，点击到的是哪个Item，记录下滑动事件的初始位置。
ACTION_MOVE：根据滑动距离，判断滑动：
上下滑动：不作处理，交给listview处理
左右滑动：将滑动事件分发给该Item，并return true，由Item处理滑动事件
ACTION_UP：当时左右滑动时，将滑动事件分发给该Item，并return true，由Item处理滑动事件

---------------------------------------------------------------------

QQ的一个聊天界面的listview每一行向左滑动的时候，会出现删除的按钮，特别炫酷，这个效果可以有，今天跟大家分享下。 
先上demo的效果图 
未滑动的时候的样子 
滑动之后的样子 
界面很丑，因为主要是介绍功能，界面什么的，搞那么复杂，下demo的时候还浪费资源，哈哈哈。

用到的几个类（4个） 
SwipeItemLayout,SwipeListView,SwipeAdapter,FragmentTestActivity. 
SwipeItemLayout就是listView的一个item，这个类集成了FrameLayout。SwipeListView是重写的一个ListView,其实主要在她的OnTouch事件的处理上。SwipeAdapter是一个adapter，这个不用解释了，FragmenTestActivity这个就是怎么用的了。 
好，一个一个来

首先我们看一个item怎么写，先上代码，代码里面基本上有逐行的解释。

唉，实在是很麻烦，其实代码不难，就是很繁琐，各种控制，各种判断，大家把这段代码中的核心的几个方法搞明白了，也就没问题了。我就不多说了哈。。。

好了，剩下的两个类，一个是adapter类，一个是用法，我就只说adapter中的一个getView方法了哈，用法的话跟一般的ListView的用法一样，对了，说adapter不就是再说用法么，哈哈哈。

在Android开发中，ListView作为早期最广泛使用的列表控件之一，其垂直滚动能力已经非常成熟。然而，在面对需要水平滑动交互的业务场景时（如商品推荐横滑、新闻头条轮播、标签页切换等），原生ListView并不直接支持横向滑动。虽然系统提供了和配合来解决此类问题，但在某些特定历史项目或轻量级需求中，仍存在通过继承并扩展ListView实现水平滑动的实际诉求。本章将围绕“如何通过对方法的重写”，构建一个可水平滑动的自定义ListView。
