Android - Language change when clicking back
android, back, onresume
Solution
After several attempts, I have found the solution to my problem. On my `onCreate` method, I get the `SharedPreferences` that contains the value of current language, and get the current language:
SharedPrefrences languagepref = getSharedPreferences("language",MODE_PRIVATE);
String language = languagepref.getString("languageToLoad", Locale.getDefault().getDisplayLanguage());
Then, in my `onResume` method, I assign the value of the above mentioned variable `language` to a local variable, and update the value of `language`. Then I compare these two variables - if they are different, I will destroy the current activity and start another:
@Override
public void onResume(){
super.onResume();
String oldLanguage = language;
language = languagepref.getString("languageToLoad", Locale.getDefault().getDisplayLanguage());
if (!oldLanguage.equals(language)){
finish();
startActivity(getIntent());
}
}
And voila, that did the trick!
Problem
I have this settings section where I allow users to change the languages displayed within the app. When the user chooses a different language, the activity is reloaded so that the change of language can be applied. But the problem is, when the user clicks back right after changing the language, the language shown in the background activity is still the same. So my question is, what should I do to apply the change of language when I get back to some activity on the background? I suppose I should do something to detect the change in `onResume` method, but I'm not sure what it is. If you have any suggestions, please let me know. Thank you.
