Case: Nested listview in ScrollView, avoid: 1. ListView displays only the first item, 2.ScrollView automatically scrolls to the first position of the ListView

1. Layout files

  
 

   
  

  

   
  

  
 <LinearLayout
   
  

  
 android:focusable="true"
   
  

  
 android:focusableInTouchMode="true"
   
  

  
 android:layout_width="match_parent"
   
  

  
 android:layout_height="wrap_content"
   
  

  
 android:orientation="vertical">
   
  

  

   
  

  
 <extra.view.MyGridView
   
  

  
 android:id="@+id/gridview"
   
  

  
 android:layout_width="match_parent"
   
  

  
 android:layout_height="wrap_content"
   
  

  
 android:horizontalSpacing="2dp"
   
  

  
 android:listSelector="#ffffff"
   
  

  
 android:numColumns="2"
   
  

  
 android:padding="2dp"
   
  

  
 android:scrollbars="none"
   
  

  
 android:verticalSpacing="2dp" />
   
  

  

   
  

  

   
  

  
 </LinearLayout>
  
 

2. Customizing the ListView

  
 

   
  

  
package com.example.chechengwang.view;
   
  

  
import android.content.Context;
   
  

  
import android.util.AttributeSet;
   
  

  
import android.widget.ListView;

public class MyListView extends ListView {
   
  

  
 public MyListView(Context context) {
   
  

  
 super(context);
   
  

  
 }
   
  

  
 public MyListView(Context context, AttributeSet attrs) {
   
  

  
 super(context, attrs);

 super(context, attrs, defStyleAttr);
   
  

  
 }
   
  

  

   
  

  
 @Override
   
  

  
 /span>public    void   Onmeasure   ( int   Widthmeasurespec     int   )    {  
   
  

  
 int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
   
  

  
 MeasureSpec.AT_MOST);
   
  

  
 super.onMeasure(widthMeasureSpec, expandSpec);
   
  

  
 }
   
  

  
}
