Android：如何执行此弹出菜单（旋转器或其他功能？）

Question

I don't understand. Is it spinner, popup or clickabel custom layout? I tried to make spinner. Created the adapter with getView and getDropDownView, but I don't understand how to make margins before the first element and after last. Also it isn't clear how insert in the middle a divider that the clickabel area of items also had an margin from a divider. As in the drawing. Gray items - pressed. Also i have tried custom spinner style

<item name="android:paddingTop">8dp</item>
<item name="android:paddingBottom">8dp</item>

spaces from above and from below have appeared, but it seems to me, it is wrong.

If you need something like Spinner with more options you can use ListPopupWindow which you can customize by extending a adapter with multiple types of items/xml.

Or just create PopupWindow looks like you want and show it as drop down .
