如何为Listview项目分隔线指定填充

Question

如何在图像中显示列表项目时如何填充.我想在布局中制作分隔线,如图所示.

这是我的列表片段代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" 
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp">

 <ListView 
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
     android:id="@+id/listV_main"
    android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"/>

这是我的List部分代码

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="10dp"
android:paddingTop="10dp"
android:paddingRight="10dp"
android:paddingBottom="10dp">
<include
    android:id="@+id/list_item_section_text"
    layout="@android:layout/preference_category"
     />

这是我的清单项目代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight"
android:adjustViewBounds="true"
android:paddingRight="?android:attr/scrollbarSize"
   >
<ImageView
    android:id="@+id/showlist_item_entry_drawable"
    android:layout_width="82dp"
    android:adjustViewBounds="true"
    android:layout_height="68dp"
    android:scaleType="fitXY"
    android:paddingLeft="9dp"/> 
<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="10dip"
    android:layout_marginRight="6dip"
    android:layout_marginTop="6dip"
    android:layout_marginBottom="6dip"
    android:layout_weight="1"
>
    <TextView android:id="@+id/list_item_entry_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:ellipsize="marquee"
        android:fadingEdge="horizontal" /> 
    <TextView android:id="@+id/list_item_entry_summary"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/list_item_entry_title"
        android:layout_alignLeft="@id/list_item_entry_title"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:singleLine="true"
        android:textColor="?android:attr/textColorSecondary" />
</RelativeLayout>

使用'插入' .....

(list_divider.xml)

<?xml version="1.0" encoding="UTF-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:insetLeft="50dp"
    android:insetRight="50dp" >

 <shape>
    <solid android:color="@color/orange" />
    <corners android:radius="2.0dip" />
</shape>

</inset>

并在列表视图中添加如下...

<ListView
    android:dividerHeight="2dp"
    android:divider="@drawable/list_divider"
    ...
/>

你可以根据需要设置插入值...

UPDATE

正如@Giulio Piancastelli所指出的,如果列表容器的背景与列表项的背景不同,那么你可以使用'layer-list' ...

(list_divider.xml)

  <?xml version="1.0" encoding="utf-8"?>
  <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >  
   <item>
        <shape android:shape="rectangle" >
            <solid android:color="@color/list_background" />
        </shape>
    </item>


    <item
        android:left="10dp"
        android:right="10dp">
        <shape android:shape="rectangle" >
            <solid android:color="@color/divider_color"/>
        </shape>
    </item>

        </layer-list>

并在列表视图中添加如下...

<ListView
    android:dividerHeight="2dp"
    android:divider="@drawable/list_divider"
    ...
/>

你需要填充分隔线？创建自定义drawable-shape为:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:left="10dp"
        android:right="10dp">
        <shape android:shape="rectangle" >
            <solid android:color="@android:color/black" />
        </shape>
    </item>

</layer-list>

并在xml中设置为ListView的分隔符:

<ListView
    android:dividerHeight="2dp"
    android:divider="@drawable/custom_divider"
    ...
/>

UPD

我只是ListView在xml中:

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:dividerHeight="2dp"
android:divider="@drawable/line"
/>

分频器作为line.xml在drawable:

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
        <item
        android:left="10dp"
        android:right="10dp">
        <shape android:shape="rectangle" >
            <solid android:color="@android:color/black" />
        </shape>
    </item>
</layer-list>

不要对ListView代码进行任何修改.如果资源构建错误,您可以尝试使用Clean.
