嵌套的preferences.xml

Nested preferences.xml(嵌套的preferences.xml)

问题描述

Is it somehow possible to include one preferences.xml into another, like it can be done for layouts with the <include /> tag?

Let's say:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen 
    xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceScreen 
        android:title="@string/pref_group_title_visual">
        <include 
            preferences_filename="xml/pref_visual"/>
    </PreferenceScreen>
...

Solution here it is to inflate both preference files from PreferencesActivity. For example:

    addPreferencesFromResource(R.xml.options);
    addPreferencesFromResource(R.xml.additional_options);
