自定义的Gridview，嵌入ScrollView会出现GridView数据显示不全的情况，类似的有ListView嵌套在ScrollView中、GridView嵌套ListView.....

就是修改嵌套组件的高度，类似的宽度也是一样
package com.text;

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

public class MyGridView extends GridView{

public MyGridView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

public MyGridView(Context context, AttributeSet attrs) {
super(context, attrs);
}

public MyGridView(Context context) {
super(context);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int h = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, h);
}

}
