Give each group a unique id like this:
为每个组提供一个唯一的 id，如下所示：
<group android:checkableBehavior="single"
android:id="@+id/group1">
It'll draw those lines for you between any two groups.
它会为您在任何两个组之间划出这些界限。
EDIT: Since the line is now showing but it's black on the black background, refer to this questionto see how to change the color of the divider.
编辑：由于线条现在显示但在黑色背景上是黑色的，请参阅此问题以了解如何更改分隔线的颜色。
