Listview或者GridView嵌套在ScrollView中只显示一行item解决方法。

页面里有ListView（GridView）和一些固定布局让他们一起在整个屏幕上滚动方法：

一、解决办法。（可用）

（1）自定义ListView（GridView），重写onMeasure()方法，我以GridView为例（ListView只需要extends ListView）具体代码如下：

 1 public class AntGridView extends GridView {
 2 
 3     public AntGridView(Context context) {
 4         super(context);
 5     }
 6 
 7     public AntGridView(Context context, AttributeSet attrs) {
 8         super(context, attrs);
 9     }
10 
11     public AntGridView(Context context, AttributeSet attrs, int defStyle) {
12         super(context, attrs, defStyle);
13     }
14     /*重点在这里重写onMeasure()*/
15     @Override
16     protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
17         int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
18                 MeasureSpec.AT_MOST);
19 
20         super.onMeasure(widthMeasureSpec, expandSpec);
21     }
22 
23 
24 }

(2)在布局文件中将整个布局放在ScollerView中，要使用的GridView或者ListView使用自定义的HeaderGridView,具体xml代码如下：

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:orientation="vertical">
 6     
 7     <ScrollView
 8         android:layout_width="match_parent"
 9         android:layout_height="match_parent">
10 
11         <LinearLayout
12             android:layout_width="match_parent"
13             android:layout_height="wrap_content"
14             android:orientation="vertical">
15             <LinearLayout
16                 android:layout_width="match_parent"
17                 android:layout_height="180dp"
18                 android:background="#00aa00">
19                 
20             </LinearLayout>
21 
22             <!-- 一定要是自定义View的包名和类名 -->
23             <top.ant.view.AntGridView
24                 android:id="@+id/ant_live_index_gridview"
25                 android:layout_width="match_parent"
26                 android:layout_height="match_parent"
27                 android:numColumns="2">
28 
29             
30             </top.ant.view.AntGridView>
31         </LinearLayout>
32     </ScrollView>
33 
34 
35 </LinearLayout>

二、动态计算子view的高度，传给ScrollView

 1 public void setListViewHeightBasedOnChildren(ListView listView) {    
 2     ListAdapter listAdapter = listView.getAdapter();     
 3     if (listAdapter == null) {    
 4         return;    
 5     }    
 6   
 7     int totalHeight = 0;    
 8     for (int i = 0; i < listAdapter.getCount(); i++) {    
 9         View listItem = listAdapter.getView(i, null, listView);    
10         listItem.measure(0, 0);    
11         totalHeight += listItem.getMeasuredHeight();    
12     }    
13   
14     ViewGroup.LayoutParams params = listView.getLayoutParams();    
15     params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));    
16     ((MarginLayoutParams)params).setMargins(10, 10, 10, 10);  
17     listView.setLayoutParams(params);    
18 }
