The thing is...I want to use PreferenceActivity to add a new row in my custom list view. So my preference ativity will consist of a few EditTextPreferences, my custom TimePickerPreference and a coulpe of ListPreferences... Like this: http://www.google.com/help/hc/images/android/android_ug/168567.5.png . The question is how they added buttons on the bottom? And.. is it possible to use OnClickListener for obtaining inputed values and how? Thanks!
A PreferenceActivity inherits from ListActivity. By default, ListActivity creates its own ListView, but you can supply your own layout via setContentView(), so long as your ListView in the layout has the right android:id. Here is the layout for the alarm activity.
