也许你可以尝试在最外层的布局中添加android:layout_marginTop = "15dp"和android:layout_marginBottom = "15dp"

如果你想显示一个带边距的分隔符，而不拉伸它-使用InsetDrawable(大小必须是一种格式，关于它说@Nik Reiman):

ListView:

<ListView
    android:id="@+id/listView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:cacheColorHint="#00000000"
    android:divider="@drawable/separator_line"
    android:dividerHeight="10.0px"/>

@drawable / separator_line:

<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:insetLeft="5.0px"
    android:insetRight="5.0px"
    android:insetTop="8.0px"
    android:insetBottom="8.0px">

    <shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="rectangle">
        <gradient
            android:startColor="@color/colorStart"
            android:centerColor="@color/colorCenter"
            android:endColor="@color/colorEnd"
            android:type="linear"
            android:angle="0">
        </gradient>
    </shape>
</inset>

我发现了一个不太好的解决方案，在这种情况下，你正在使用一个HorizontalListView，因为分隔器似乎不与它一起工作，但我认为它将工作为更常见的ListView。

添加:

<View
android:layout_marginBottom="xx dp/sp"/>

在布局的最底部视图中，您在适配器类中膨胀将在项目之间创建间距

也许你可以尝试在最外层的布局中添加android:layout_marginTop = "15dp"和android:layout_marginBottom = "15dp"

对于我的申请，我已经这样做了

 <ListView
    android:id="@+id/staff_jobassigned_listview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@null"
    android:dividerHeight="10dp">

</ListView>

只需要将分隔符设置为null，并为我提供高度。

例子:

android:divider="@null"

or

android:divider="@android:color/transparent"

这就是结果

Although the solution by Nik Reiman DOES work, I found it not to be an optimal solution for what I wanted to do. Using the divider to set the margins had the problem that the divider will no longer be visible so you can not use it to show a clear boundary between your items. Also, it does not add more "clickable area" to each item thus if you want to make your items clickable and your items are thin, it will be very hard for anyone to click on an item as the height added by the divider is not part of an item.

幸运的是，我找到了一个更好的解决方案，既可以显示分隔符，又可以使用空白来调整每个项目的高度。这里有一个例子:

列表视图

<ListView
android:id="@+id/listView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>

ListItem

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="10dp"
    android:paddingTop="10dp" >

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:text="Item"
        android:textAppearance="?android:attr/textAppearanceSmall" />

</RelativeLayout>
