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

需要的权限

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
