This must come up very often.
When the user is editing preferences in an Android app, I'd like them to be able to see the currently set value of the preference in the
Example: if I have a Preference setting for "Discard old messages" that specifies the number of days after which messages need to be cleaned up. In the
PreferenceActivity I'd like the user to see:
"Discard old messages" <- title
"Clean up messages after x days" <- summary where x is the current Preference value
Extra credit: make this reusable, so I can easily apply it to all my preferences regardless of their type (so that it work with EditTextPreference, ListPreference etc. with minimal amount of coding).
