这是我工作正常的代码，我只想在listview. 所以，我的问题是如何在listview. 注意：我只想添加边框，我可以在哪里放置边框？任何帮助将不胜感激。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"/>

listview_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="@drawable/listview_selector_focussed" />
<item android:state_pressed="true" android:drawable="@drawable/listview_selector_pressed" />
</selector>

listview_selector_focussed.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient android:startColor="#0a89f1" android:endColor="#56768d" android:angle="90" />
</shape>

listview_selector_pressed.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient android:startColor="#0a89f1" android:endColor="#56768d" android:angle="90" />
</shape>

添加页眉和页脚，它们将作为边框

  1. 在您的活动中，您将声明您的ListView;

    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);

  2. 在您的父布局元素的布局文件中

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