嘗試的LinearLayout –

5填充如果列表視圖佔據整個屏幕，然後你可以添加邊框到你的佈局，inturn將看起來好像圍繞着listView。看看這個鏈接：http://stackoverflow.com/questions/8203606/android-how-to-draw-a-border-to-a-linearlayout – Zax

試試這個：

<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" />

希望這有助於。

什麼是android：background =「@ drawable/listviewborder」 – user2659385

你忘了添加背景到你的列表視圖，所以列表視圖不顯示邊框。 – user2652394

創建邊境一個XML文件，然後以此爲繪製與列表視圖

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" 
/>
