当我们用ScrollView嵌套listview和GridVIew的时候，经常会遇到listview中的内容不能全部显示问题，想要解决这个问题也很简单，只要我们重写listview和gridview这俩个空间就可以了，具体步骤和方法如下。

1自定义lisetview控件

package com.yhkj.jskf.southwestcementmt_salesman.utils;

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

public class MY ListView extends ListView {

public AllListView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}

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

}

package com.yhkj.jskf.southwestcementmt_salesman.widget;

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

/**
* 自定义GridView控件
* @Type: MyGridView 让GridView可以做ScrollView的子控件，但尺寸不会减小
*/
public class MyGridView extends GridView {

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

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

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

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
}

2在xml中引用自定义的控件

<com.yhkj.jskf.southwestcementmt_salesman.utils.AllListView
android:divider="#cccccc"
android:id="@+id/lv"
android:cacheColorHint="#00000000"
android:dividerHeight="1dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/ll_allcontent"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:scrollbars="none" >
</com.yhkj.jskf.southwestcementmt_salesman.utils.AllListView>

<com.yhkj.jskf.southwestcementmt_salesman.widget.MyGridView
android:id="@+id/gvNetworkInformation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:horizontalSpacing="5dp"
android:numColumns="3"
android:verticalSpacing="10dp" />

3在activity里引用这两个控件就ok了，

以上问题就解决了
