Answer 1

为border创建一个xml文件，然后将其用作listview的可绘制文件

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"
 />

Answer 2

试试这个：

<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" />

希望这有帮助。
