android如何在listview中设置边框

这是我的代码，工作正常，我只想在

列表视图的顶部和底部添加边框。所以，我的问题是如何在
列表视图的顶部和底部添加边框。注意：我只想添加边框，在哪里可以放置边框？任何帮助都将不胜感激。谢谢

<ListView android:id="@+id/listCategory"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:fadeScrollbars="true"
          android:fastScrollEnabled="true"
          android:listSelector="@drawable/listview_selector"
          android:dividerHeight="1dp"
          android:layout_below="@+id/gridlayout"
          android:visibility="gone"/>

添加页眉和页脚，它们将用作边框

在您的活动中，您将声明您的
列表视图

View v=new View(this);
v.setLayoutParams(new LayoutParams(<width>,>height>));
v.setBackgroundColor(<your color>);
ListView list=(ListView)findViewById(R.id.listCategory);
list.addHeader(v);
list.addFooter(v);

View v=新视图（该视图）；
v、 setLayoutParams（新的LayoutParams（，>高度>）；
v、 setBackgroundColor（）；
ListView列表=（ListView）findViewById（R.id.listCategory）；
列表.添加标题（v）；
列表.添加页脚（v）；

在父布局元素的布局文件中

<YourParentLayoutElement
...
android:paddingTop="<your_value>"
android:paddingBottom="<your_value>"
>



是否使用自定义列表视图？对列表视图使用页眉页脚视图
