When doing Android Development where can I find a list all the valid XML attributes for the Button element?
I have tried looking at the schema http://schemas.android.com/apk/res/android, but that is just a place holder of some kind because nothing exists at the URL. 

A:

The documentation for Button lists the documented XML attributes. There are not specifically for Button, just those inherited from TextView (and View). If you go by the sources, you may find an attribute that appears to be supported, but if it's undocumented, the support could go away in a future version of the OS.
