Referencing another layout.xml file without duplicating it

Question

I need to provide the same layout.xml file for an Activity for several different qualifiers. I know that there\'s a way to just reference one existing layout.xml instead of

Answer 1

Create a wrapper layout my_activity.xml and your layouts for small and xlarge devices.

Your resources should look like:

layout
  -> my_activity.xml
  -> my_activity_small.xml
  -> my_activity_xlarge.xml

Now override my_activity.xml in layout-xlarge and layout-sw600dp:

Your ressources should look like:

layout
  -> my_activity.xml           <-- includes my_activity_small.xml
  -> my_activity_small.xml
  -> my_activity_xlarge.xml
layout-xlarge
  -> my_activity.xml           <-- includes my_activity_xlarge.xml
layout-sw600dp
  -> my_activity.xml           <-- includes my_activity_xlarge.xml

Use my_activity.xml in your code for loading the layout.

P.S.: You can not point to a layout in another qualifier's directory, as you mentioned in one of the comments.
