Represents a top-level Preference that is the root of a Preference hierarchy. A PreferenceActivity points to an instance of this class to show the preferences. To instantiate this class, use createPreferenceScreen(Context).

This class can appear in two places:

  • When a PreferenceActivity points to this, it is used as the root and is not shown (only the contained preferences are shown).
  • When it appears inside another preference hierarchy, it is shown and serves as the gateway to another screen of preferences (either by showing another screen of preferences as a Dialog or via a startActivity(android.content.Intent) from the getIntent()). The children of this PreferenceScreen are NOT shown in the screen that this PreferenceScreen is shown in. Instead, a separate screen will be shown when this preference is clicked.
