The preferences portion of an application should be ran as a separate Activity
that extends the PreferenceActivity
class. In the PreferenceActivity, a PreferenceScreen
object should be the root element of the layout. The PreferenceScreen contains Preference
elements such as a CheckBoxPreference
, EditTextPreference
, ListPreference
, PreferenceCategory
, or RingtonePreference
.
All settings made for a given Preference
will be automatically saved to the application's instance of SharedPreferences
. Access to the SharedPreferences is simple with getSharedPreferences()
.
Note that saved preferences are accessible only to the application that created them.
