PreferenceScreen複数のPreference CategorysとでシンプルにしましたCheckBoxPreferences。
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="General">
<CheckBoxPreference
android:title="GPS"
android:key="gps_preference"
android:summary="Enales the GPS tracking of your device"
android:defaultValue="true"
></CheckBoxPreference>
<SwitchPreference
android:title="WLAN"
android:key="wlan_preference"
android:summary="Enables the WLAN usage"
android:defaultValue="true"></SwitchPreference>
<CheckBoxPreference
android:title="Benachrichtigungen"
android:key="benachrichtigung_preference"
android:summary="Enables the Push messages"
android:defaultValue="true"
></CheckBoxPreference>
</PreferenceCategory>
</PreferenceScreen>

CheckBoxPreferenceただし、 a の1 つを切り替えたい場合( withSwitchPreferenceの xml タグを切り替えるだけで機能するはずです)、タブでレンダリング エラーが発生します。CheckBoxPreferenceSwitchPreferencedesign
レンダリング中に例外が発生しました: android.preference.CheckBoxPreference は android.preference.GenericInflater$Parent にキャストできません
