In the Android Settings section of the Material Design Guidelines, it mentions that section titles are optional for preference groupings, and in the image, the last section shows a grouping without a title but with a divider between groupings.
However, I am not able to implement this properly. If I use a PreferenceCategory with no title set, there is a blank space where the title would be. I can't just throw in a View in a PreferenceScreen to a draw a divider, and the promising looking PreferenceGroup is abstract or otherwise not able to be used.
So, how can I achieve this?
You can get the divider using app:allowDividerAbove="true" or app:allowDividerBelow="true" as per your need. Using PreferenceCategory tag is not needed as these attributes can be set in any level of preference hierarchy.
