ScrollView嵌套GridView

關於ScrollView嵌套GridView的一些問題以及解決方法。重寫GridView決絕嵌套問題。

【遇到坑】：

在調到次頁面時，顯示的不是Scrollview頂部，而是當前GridView位置

【解決】：

直接設置ScrollView是沒有什麼效果的，要先讓gridview取消焦點，再設置ScrollView初始位置

mGridView.setFocusable(false);

mScrollView.scrollTo(0, 0);//設置scrollview初始位置

【代碼】：

package com.zoommax.car.view;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.GridView;
