Hi All:
When I see the doc of Preference Screen, there is one paragraph
about the sub-preference screen related to dialog, the doc is as
follow:
---> 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 Context.startActivity(android.content.Intent) from the
Preference.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.
But in Android Api Demo, the Preference from code, I find nothing
related to Dialog when using PreferenceScreen as the base element of
preference, and I have no idea about 'showing another screen of
preferences as a Dialog', what does it mean? Is there a pop-dialog
when we click anywhere in Preference Screen? But the Preference Screen
is invisible. So I wanna know if there is any suggestion about my
question, and thanks in advance!
