}

@SuppressLint（“ ValidFragment”）公共类PrefsFragment扩展了LeanbackPreferenceFragment {

@Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
    // Load the preferences from an XML resource
    setPreferencesFromResource(R.xml.preferences, rootKey);
}

}

我通过更改主题首选项 Theme.Leanback

解决了此问题

在清单文件上：

<activity android:name=".ui.setting.YourSettingPrefActivity"
        android:exported="true"
        android:theme="@style/Theme.Pref.LeanbackPreferences"/>

这里是styles.xml

<style name="Theme.Pref.LeanbackPreferences" parent="Theme.Leanback">
    <item name="preferenceTheme">@style/PreferenceThemeOverlay.v14.Leanback</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:colorPrimary">@color/fastlane_background</item>
</style>
