I am making an app in which I want to have a page where I show a language selection page. So far I've included English, Hindi, and Marathi, with English set as the default.
My question is:
how to change the whole application language in Selected Language?
After choose the language whenever I reopen the application its give previous chosen language?
Put your all text in String file. For each language create separate String file(Deutsch values-de/strings.xml, French values-fr/strings.xml) and while you need to change language call following function. For English language set "en" for another set corresponding key
#Kotlin
val config = resources.configuration val locale = Locale("en") Locale.setDefault(locale) config.locale = locale resources.updateConfiguration(config, resources.displayMetrics) #Android Java
Configuration config = getBaseContext().getResources().getConfiguration(); Locale locale = new Locale("en"); Locale.setDefault(locale); config.locale = locale; getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); 
String lang= "en"; public void changeLang(String lang) { Configuration config = getBaseContext().getResources().getConfiguration(); if (!"".equals(lang) && !config.locale.getLanguage().equals(lang)) { locale = new Locale(lang); Locale.setDefault(locale); Configuration conf = new Configuration(config); conf.locale = locale; getBaseContext().getResources().updateConfiguration(conf, getBaseContext().getResources().getDisplayMetrics()); } } Try out this method....This will definitely work.. As you select your preferred language, pass your selected language code in this method and this will change the language of whole application.
