ExpandableListView 中嵌套 gridview

ExpandableListView 中嵌套 gridview ，都是viewgroup 这样嵌套的话 gridview只会显示一行

原因： 就是有滚动条的控件里放有滚动条的控件就会出现只显示一两行的问题,,解决的办法就是, 把子控件设置为没有滚动条. 具体就是自定义控件.
把GridView自定义一下,代码如下,然后用这个自定义的控件就行了

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
     >

    <com.example.mygridview.MyGridview
        android:id="@+id/gridView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:numColumns="3"
        android:columnWidth="80dp"
        android:stretchMode="columnWidth"
        android:background="@drawable/background">
    </com.example.mygridview.MyGridview> 

</LinearLayout>

/////////////////////////////////////////////////////////////////////////类这样写就是了，这也算自定义组件

package com.example.mygridview;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.GridView;
public class MyGridView extends GridView
{
public MyGridView(android.content.Context context,
android.util.AttributeSet attrs)
{
super(context, attrs);
}

/**
* 设置不滚动
*/
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);

}

}

 

//要想该界面除了显示ExpandableListView 还显示别的view的话

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>

<TextView
android:id="@+id/textView2"
android:layout_width="match_parent"
android:layout_height="55dp"
android:text=""
android:gravity="center"
android:background="@drawable/backgroud003"
/>

<ExpandableListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</ExpandableListView>

</LinearLayout>
