Edit Question
Title
Body
I am looking at the Honeycomb Gallery sample code ( here ) and I ran across the following code while trying to add action items in my own app: <item android:id="@+id/camera" android:title="Camera" android:icon="?attr/menuIconCamera" android:showAsAction="ifRoom" /> The ?attr is throwing me for a loop. Can someone please explain what this is doing? How is this related to a drawable? I can't seem to find any good information on Google. Also is there a listing or gallery of attributes we can use for icons instead of just menuIconCamera ? Thanks Edit: I did some more looking around and found that attrs.xml looks like this: <resources> <declare-styleable name="AppTheme"> <attr name="listDragShadowBackground" format="reference" /> <attr name="menuIconCamera" format="reference" /> <attr name="menuIconToggle" format="reference" /> <attr name="menuIconShare" format="reference" /> </declare-styleable> Unfortunately that just makes it even more confusing for me. What is this doing?
