更改列表首选项时刷新首选项片段

Question

I'm designing an application that supports 3 languages. I have added an option to select the language in preference fragment. The locale in the preference fragment will not change immediately after selecting the language from ListPreference .
But if I navigate back to MainActivity and come back to SettingsActivity the locale will be changed in the preference screen as well.

I need a solution to change the locale in the PreferenceFragment as soon as there is a change in the ListPreference value (ie when the language is selected.)

Any help appreciated.

UPDATE : Now I'm using custom list preferences class CustListPreference that extends ListPreference and implements DialogInterface.OnClickListener

I have defined an OK button in the list preference. Now in the OnClick method when ok is pressed I'm updating the configuration using

getContext().getResources().updateConfiguration(config, null); , but no luck. The view is not getting updated.

Some one please suggest me how to refresh the activity or restart onClick of OK button.

Answer 1

You need to restart you activity, after changing the locale.

Or Try updating configuration, something like that:

public void changeLanguage(Configuration configuration) {
    configuration.locale = Locale.ENGLISH;//or other locale

    Locale.setDefault(configuration.locale);
    getBaseContext().getResources().updateConfiguration(configuration, null);
}
