You can declare IDs in your res/values/resources.xml file, like this: <resources> <item type="id" name="common_control_01"/> <item type="id" name="common_control_02"/> </resources>
Then, refer to the id in your layout simply with @id/common_control_01 If you have a bunch of common IDs, this might be a good approach.
