Thanks for digging a bit deeper.
I copied what you did and indeed got the click handled!
The difference was that my subclass then referred to another layout xml
file that actually showed a button as in this discussion (
http://stackoverflow.com/questions/5298370/how-to-add-a-button-to-a-preferencescreen-android
).
I stepped back to what you did and got the same results. I think the next
step is to subclass the button and handle it the way you suggested for
subclassing Preference.
As for my comments, my Russian is rusty, however, I am very pleased with
the developer community and have found some very helpful people such as
yourself. I'm just surprised that it has been so difficult to find
information on how to create the "new", "modern" style preference screen.
Without people such as yourself, it would not be possible at all. At
least for mortals such as myself.
Thanks again!
B.
