Answer 1

Essayez ceci:

<ListView 
      android:id="@+id/listMainMenu" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:background="@drawable/listviewborder" <!-- HERE --> 
      android:listSelector="@drawable/listview_selector" 
      android:dividerHeight="1dip" 
      android:fadeScrollbars="true" /> 

Hope this helps.

Answer 2

Créez un fichier xml pour la frontière puis utilisez cela comme un drawable avec listview

border.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:padding="10dp" 
    android:shape="rectangle" > 

    <solid android:color="#00000000" /> 

    <stroke 
     android:width="2dp" 
     android:color="#808080" /> 

    <corners 
     android:bottomLeftRadius="10dp" 
     android:bottomRightRadius="10dp" 
     android:topLeftRadius="10dp" 
     android:topRightRadius="10dp" /> 

</shape> 

<ListView 
     android:background="@drawable/border" 
/>
