ScrollView嵌套ListView嵌套GridView的上下拉以及加載更多

ScrollView 效果

ScrollView 說明

一個ScrollView 嵌套ListView 嵌套GridView的上拉加載更多，下拉刷新的demo。
主要是重寫了GridView和LsitView中的onMeasure 方法。
寫的比較簡單，希望對初學者有幫助。

/***
* 主要思路是
* ScrollView 嵌套ListView 嵌套GridView的上拉加載更多，下拉刷新。
* 
* 邏輯在適配器做了處理
* 
* 我們只讓ListView加載2個數據Item，第一個是item對象，第二個是一個對象
*
