Immediately make a reservation, the solutions from the English SO did not help me. Tried this , this , and this ,

Well, first things first:

I decided to get away from the PreferenceActivity + PreferenceFragment bundle, leaving only the PreferenceFragment , first yielded the PreferenceFragment from the system, but it was layered on fragments from the support library, painted itself on top of the interface.

I did not like this behavior, and I decided to try PreferenceFragmentCompat, from the library android.support.preference-v7 , version 25.3.1

 compile "com.android.support:preference-v7:${supportLibVersion}"

The transaction fragment is as follows:

 getSupportFragmentManager().popBackStack(); getSupportFragmentManager() .beginTransaction() .replace(R.id.frame_container, new SettingsFragment()) .commit();

But when I run the fragment, I get this error.

 java.lang.IllegalStateException: Must specify preferenceTheme in theme

I have 2 themes, I indicated this attribute in them: <item name="preferenceTheme">@style/PreferenceThemeOverlay</item> error did not disappear, I tried to use the compile 'com.takisoft.fix:preference-v7:25.3.1.0' fixed library compile 'com.takisoft.fix:preference-v7:25.3.1.0' all the same. I tried to set my style - it's useless.

Fixed fragment code by library:

 public class SettingsFragment extends PreferenceFragmentCompat { SharedPreferences preferences; @Override public void onCreatePreferencesFix(Bundle savedInstanceState, String pref) { super.onCreate(savedInstanceState); preferences = PreferenceManager.getDefaultSharedPreferences(getActivity()); setPreferencesFromResource(R.xml.setting, pref); setHasOptionsMenu(true); Preference ThemePref = findPreference("ITheme.Theme"); if (ThemePref != null) { ThemePref.setOnPreferenceClickListener(preference -> { try { String[] items = new String[]{"LIGHT", "DARK"}; new MaterialDialog.Builder(getActivity()) .items(items) .itemsCallback((dialog, view, i, items1) -> { switch (i) { case 0://LIGHT preferences.edit().putInt("ITheme.Theme", ThemeInterfacer.LIGHT).apply(); ThemeInterfacer.setAppTheme(getActivity(), ThemeInterfacer.LIGHT); break; case 1://DARK preferences.edit().putInt("ITheme.Theme", ThemeInterfacer.DARK).apply(); ThemeInterfacer.setAppTheme(getActivity(), ThemeInterfacer.DARK); break; default: break; } }) .show(); return true; } catch (Throwable throwable) { Toasty.error(getActivity(), Arrays.toString(throwable.getStackTrace()), Toast.LENGTH_LONG, false).show(); throwable.printStackTrace(); } return false; }); } } @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { if (menu != null) { menu.clear(); } else menu = new MenuBuilder(getActivity()); menu.add("Test").setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_ALWAYS); } }

    It is extremely reluctant to understand your code, just give an excerpt from their styles with a declaration of styles for PreferenceFragmentCompat

     <!-- Light application theme --> <style parent="Theme.AppCompat.Light.DarkActionBar" name="AppTheme.Light"> <item name="preferenceTheme">@style/PreferenceThemeOverlay.v14.Material</item> <item name="android:alertDialogStyle">@style/TransparentAlertDialogStyle</item> <item name="dialogTheme">@style/ControlDialogStyle.Light</item> <item name="colorPrimary">@color/primaryColorLight</item> <item name="colorPrimaryDark">@color/primaryColorDark</item> <item name="cardStyle">@style/CardView.Light</item> <item name="hintColor">@color/hintColorLight</item> <item name="actionColor">@color/white</item> <item name="android:dialogTheme">@style/ControlDialogStyle.Light</item> </style>

    I hope the idea is clear. In essence, there is a reference to the system theme: @style/PreferenceThemeOverlay.v14.Material , which provides the availability of the desired theme.

    • Thank you, I understood my mistake. I added an attribute only to values, and forgot to values-21. Therefore, it fell. - De-Bill
