Hi, I've spent over a week trying to figure out a way to do a Limited Multi Selection Preference list. Nothing I've tried works.

I don't want to use EditTextPreference. So do I have to use a default Button in the PreferenceActivity and save the settings for it manually? Regards, cody ...
I've got a DialogPreference which implements a simple TimePicker.OnTimeChangedListener (see below). Setting the time by clicking the +/- buttons works great. But I don't know how to save the state of the timepicker when the user typed in the time directly into the textfield. It could be sufficient to access to the current textfield value...
