android自定义控件自动换行效果实现

第一篇博客里面有介绍一篇关于自动换行实现诸多自定义控件跟各种效果的博文，但是碍于当初技术能力有限，写的jar包里的代码乱七八糟，在最近忙完了手头的工作，不经意间翻看了之前的代码，真是惨不忍睹，随决定重新封装。重新编写的android-custom-vg前后修改了多次版本暂定为2.6.0，模拟的ListView加载数据的流程，为了更方便的使用。只做了最基础的效果，ListView中定位某个View显示的属性，则没有被实现。

自定义控件换行效果jar调用API：

setDividerWidth(int dividerWidth); //设置两个Item的水平间距，第一个Item距离左边框距离为0

setDividerHeight(int dividerHeight); //设置两个Item的垂直间距，第一行Item距离顶部边框距离为0

setOnItemClickListener(OnItemClickListener listener); //获取Item的点击事件

setOnItemLongClickListener(OnItemLongClickListener listener); //获取Item的长按事件

效果图：

1、activity_main.xml：为了实现滑动效果，把自定义控件放进ScrollView控件中
