Is it possible to create an individual preference in an PreferenceScreen ? I would like to code color settings like that: I know that choosing the color is easy realizable with the ListPreference , but it would be awesome with that kind of "checkboxes". Dave The Android Developer page only shows how to make a DialogFragment . It's still possible to customise the appearance of a Preference item though.

After I upgraded to the Support Library v21 my ActionBar in my PreferenceActivity is gone. Did I miss some attributes in my theme to activate it again?

问题 Trying the different preference activities in the ApiDemos for Android 4.0, I see in the code that some methods are deprecated in PreferencesFromCode.java, for example.

问题 I am using a PreferenceActivity to show some settings for my application.
