ScrollView嵌套ListView嵌套GridView的上下拉以及加载更多

ScrollView 效果

ScrollView 说明

一个ScrollView 嵌套ListView 嵌套GridView的上拉加载更多，下拉刷新的demo。
主要是重写了GridView和LsitView中的onMeasure 方法。
写的比较简单，希望对初学者有帮助。

/***
* 主要思路是
* ScrollView 嵌套ListView 嵌套GridView的上拉加载更多，下拉刷新。
*
* 逻辑在适配器做了处理
*
* 我们只让ListView加载2个数据Item，第一个是item对象，第二个是一个对象
*
