The launched MainActivity uses the FragmentManager to load the PreferenceFragmentCompat into the activities root view. The cool think here is you can see how a built-in application - that is the browser can be called form the MainActivity to to display a webpage. And in this XML we can see that an Intent is fired and the data past to the browser in this case is the. The class below is a snippet from the XML. Like for other preference types, we assign a key (e.g., android:key='checkbox_preference') here so it is able to save and restore its instance state. This PreferenceScreen tag serves as a screen break (similar to page break in word processing). The preference framework handles showing these other screens from the preference hierarchy.

screen preferences will launch a new screen for input.

edit text preference will launch a dialog to enter text.

This is determined by the type of preference object that is specified for example: If you tap any of the preferences you will go to a dialog or new screen.

As you an see from the xml and running the example that another PreferenceScreen in the hierarchy denote a screen break-that is the preferences contained within subsequent PreferenceScreen should be shown on another screen. The PreferenceScreen object should be at the top of the preference hierarchy. First not that you have to create a to specifying the hierarchy. There are a large number of example preferences shown in the preference.xml example. You should just set up a new folder call it xml and the create preference.xml and save it there. The preference.xml file is set up in 'res/xml'. To retrieve an instance of SharedPreferences that the preference hierarchy in this fragment will use, call PreferenceManager.getDefaultSharedPreferences() with a context in the same package as this fragment. These preferences will automatically save to SharedPreferences (which we discussed earlier in the course) as the user interacts with them. PreferenceFragmentCompat contains a hierarchy of preference objects as lists. This is a simple and powerful way to handle system preferences.

When the user interacts with the fragment there is no code needed to create dialogs or new screens to handle input from the user or storage. The example we discuss below does 90% of the work in XML and very little code. It is easy to create a hierarchy of preferences (that can be shown on multiple screens) via XML.
