我PreferenceFragment在ActionBarActivitysupport-v7库中使用.
在我的活动中Toolbar.一切顺利,直到我打开一个嵌套PreferenceScreen.
在打开的屏幕Toolbar中隐藏.

也许有人知道这个问题的解决方法？

首选项xml文件:

<?xml version="1.0" encoding="utf-8"?>
    <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >

    <PreferenceCategory android:title="Main category" >

        <EditTextPreference
            android:defaultValue="defaultValue"
            android:key="key_global_setting"
            android:title="Global title" />        

    </PreferenceCategory>

    <PreferenceCategory android:title="Nested screens" >        

        <PreferenceScreen
            android:persistent="false"
            android:title="@string/settings_facility_title" >

        <CheckBoxPreference
            android:defaultValue="false"
            android:key="nested_screen_1_1"
            android:title="Nested screen 1.1 check box" />

        <CheckBoxPreference
            android:defaultValue="true"
            android:key="nested_screen_1_2"
            android:title="Nested screen 1.2 check box" />
        </PreferenceScreen>

        <PreferenceScreen
            android:persistent="false"
            android:title="@string/settings_menu_screen_title" >

         <CheckBoxPreference
            android:defaultValue="true"
            android:key="nested_screen2"
            android:title="Nested screen 2 check box" />
        </PreferenceScreen>        

    </PreferenceCategory>
