Project to use the ScrollView combined with the GridView, there are a lot of problems, here first take the ListView to open brush. The effect you want to achieve is as follows:

But the effect of the implementation is as follows:

It crashed. The layout is like this:

<scrollview xmlns:android= "http://schemas.android.com/apk/res/android"    android:layout_width= "Match_ Parent "    android:layout_height=" match_parent "     >    <listview        android:id=" @+id/list_view "        android:layout_width= "match_parent"        android:layout_height= "wrap_content" >    </ListView> </ScrollView>

Add the following properties to ScrollView:

Android:fillviewport= "true"

Run the interface is out, but the interface is not able to drag, the solution is to customize the ListView:

Package Com.example.uilistviewtest;import Android.content.context;import Android.util.attributeset;import Android.widget.listview;public class Mylistview extends Listview{public Mylistview (context context, AttributeSet attrs , int defstyleattr) {Super (context, attrs, defstyleattr);} Public Mylistview (context context, AttributeSet Attrs) {Super (context, attrs);} Public Mylistview (Context context) {super (context);} @Overrideprotected void onmeasure (int widthmeasurespec, int heightmeasurespec) {int expandspec = Measurespec.makemeasurespec (Integer.max_value >> 2, measurespec.at_most); Super.onmeasure (WidthMeasureSpec, EXPANDSPEC);}}

The new layout:

<scrollview xmlns:android= "http://schemas.android.com/apk/res/android"    android:layout_width= "Match_ Parent "    android:layout_height=" match_parent "     >    <com.example.uilistviewtest.mylistview        Android:id= "@+id/list_view"        android:layout_width= "match_parent"        android:layout_height= "Wrap_content" >    </com.example.uilistviewtest.MyListView></ScrollView>
