Description Jeremy Kolb 2012-10-31 11:55:43 UTC
I need to use droidtext (http://code.google.com/p/droidtext/) in my project but am hitting a lot of cases where field names are like the following: "_3D".  The bindings try to generate a property name "3D" for this which gets us into trouble.  I think that instead the bindings should keep the leading underscore if a number immediately follows it.
Comment 1 Atsushi Eno 2012-10-31 15:12:07 UTC
For Android API bindings such names that begin with a number are forced to be explicitly named manually, like android/view/KeyEvent.KEYCODE_3D_MODE field becomes enum value Keycode.ThreeDMode (not Keycode.3DMode which is invalid). I don't think our naming of fields are not very simple to introduce such special escaping. Also at least we believed that there shouldn't be such a lot of "public" fields whose name begin with _.

I think it shouldn't be very difficult to create such a java tool that iterates all the fields in all the classes and generate part of Metadata.xml so far.

I agree that naming fields beginning with _ is stupid.  I guess it's not a big deal because as you say there shouldn't be too many of them and we can explicitly rename them.
