     public class SettingsFragment extends LeanbackSettingsFragment {
@Override
public void onPreferenceStartInitialScreen() {

    startPreferenceFragment(new PrefsFragment());
}

@Override
public boolean onPreferenceStartFragment(PreferenceFragment caller, Preference pref) {
    final Fragment f =
            Fragment.instantiate(getActivity(), pref.getFragment(), pref.getExtras());
    f.setTargetFragment(caller, 0);
    if (f instanceof PreferenceFragment || f instanceof PreferenceDialogFragment) {
      //  startPreferenceFragment(f);
    } else {
       // startImmersiveFragment(f);
    }
    return true;
}

@Override
public boolean onPreferenceStartScreen(PreferenceFragment caller, PreferenceScreen pref) {
    final Fragment f = new PrefsFragment();
    final Bundle args = new Bundle(1);
    args.putString(PreferenceFragment.ARG_PREFERENCE_ROOT, pref.getKey());
    f.setArguments(args);
    startPreferenceFragment(f);
    return true;
}

}

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

@SuppressLint("ValidFragment") public class PrefsFragment extends LeanbackPreferenceFragment {

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

}

推荐答案

我通过更改主题首选项 Theme.Leanback

I solve this issue with changing theme preference Theme.Leanback

在清单文件上:

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

然后在styles.xml上

And here on 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>
