我想在我的listview分隔符中添加左右填充，因为每行应该在屏幕的最左侧有一个纯色，如果我在整个列表中添加填充，那么这些颜色也会被填充。我知道我可以制作自己的分频器，但我无法找到默认分频器的可画面。

我试图像这样做一个可绘制的：

    <View xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:background="?android:attr/listDivider" />

然后将其作为分隔符：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/background_pattern" >

<ListView
    android:id="@+id/status_list"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:divider="@drawable/list_divider"
    android:headerDividersEnabled="false"
    android:footerDividersEnabled="false" >
</ListView>

但应用程序部队以此结束：

以下是问题，android:divider需要@drawable或@color（请参阅docs），但您在@layout下保存了@drawable {1}}文件夹（这就是它编译的原因），但在运行时崩溃。

android.content.res.Resources$NotFoundException: File res/drawable/list_divider.xml from drawable resource ID #0x7f020007

不幸的是，我认为没有任何好方法可以引用默认的android drawable list divider AND 同时覆盖其填充/边界。如果你得到了drawable的源文件，你可以编辑9.png文件的可伸缩/内容区域来调整它的填充，但这是相当繁琐的。

这是我找到的解决方法（并且运行正常）：设置android:divider="@null"，并将分隔符View添加到row_layout.xml的底部（用于绑定到ListView）。基本上你会伪造分频器，它会在每一行内而不是在它们之间，但对于用户来说它看起来是一样的。然后，您将能够控制分隔线的填充与每行的填充分开，这是您的目标。
