I want to provide three different langauges. The default language is english so all my string values in the values folder are in enlish. I created two other folders
values-de for the german language
values-cn for the chinese language
each folder contains a strings.xml file where i defined the values in german for the de folder and in chinese for the cn folder.
My question now is: How can i load a different language programmatically because i want to provide buttons in my app interface where the user can switch the language. The settings of the device wont be editable for our users. Our users can just see the app itself and nothing else so i have to provide the language switching from within my application.
You can change the configuration at runtime
Do this in onCreate of the activity
String languageToUse = "de"; // The language you want to change
Locale locale = new Locale(languageToUse);
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());

as i know if we set android:supportsRtl="true" in manifest the app will change it's direction based on default language of the phone ..my problem is that lot's of people in my country set their default language to English whereas they know a little about English an if they open app and see the application language is English they will definetly remove the app .. so my question is is there any way to change the value inside the app . and i give them the option to change language at the beggening of the app or in setting .. ty
you can use below code to set language for app, this is for english, replace the en with you language:
Locale locale = new Locale("en");
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
in manifest file write android:configChanges="locale".
You can give them to choose language at any time, but remember all activities language are change except current activity, you have to restart current activity.
Which language does android treats default strings.xml as?
Specifically, when there are <plurals> tags inside default strings.xml, rules for which language will Android pick? Is there a way to specify that?
It doesn't treat default values folder as a language dependant. It's basically a fallback if it doesn't find a better match. You can read more here.
Android will pick plurals rules for language that is currently selected in the phone(e.g. if users has german language then android will pick german rules).
Use this to change the language by programmatically--
Locale locale = new Locale("en_US");
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
context.getApplicationContext().getResources().updateConfiguration(config, null);
Write the countrycode of language in place of "en_US" whatever language you want...like for japanese--"ja_JP" For Arabic--"ar" or check this link for code of country--

I only want set only default English language of application in android.
After Supporting Different Languages, I also use values/strings.xml to store characters in that file.
If in English language mode of System Settings, I can show correct words.
If in Chinese language mode of System Settings, The English words was translated to Chinese.
I don't want it translate automatically.
People who know how to set only default English language,
Please help me.
Thanks,
I can get correct answer now via the codes in below :
public static void setDefaultLanguage(Context context, String lang) {
Locale locale = new Locale(lang);
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
context.getResources().updateConfiguration(config,
context.getResources().getDisplayMetrics());
}
In that, what is lang value? You should get correct Language System to pass this value to lang parameter.
Thanks,
Are you storing all the strings for both languages in one .xml? If so that is probably your issue…
res/values/strings.xml
Contains English text for all the strings that the application uses,
res/values-ja/strings.xml - for japanese, but I am sure you can find one for the language you are looking for! Android looks for the "values-ja" tag.
It's very easy to place different string.xml files for multiple languages like:
English
Values
String.xml
Arabic
Values-ar
String.xml
but it only works when device language is changed. My scenario is I have to load a user selected language in the application, different from the one selected in the device so how can I load different String.xml files?
You can change the application language using the following code:
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
languageToLoad is a String variable like "en" or "ar".
I want to change my app language in my app because android languages don't have all languages i want to use. So i got this to change:
String languageToLoad = "en";
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());
However, when user opens app and change it. Then strings which is showing at that moment still are the older language it changes just when new Activity is created.
Other problem that i should somehow save what user language was select and then change language when app is started.
So how to improve this? I want that when user select language all strings would be taken from selection languages strings.xml and how to save which language user was selected?
You can use a SharedPreference to store the user's language. Here's the documentation about it: http://developer.android.com/reference/android/content/SharedPreferences.html
About the need to reload the Activity, you may find some answers here: Android: locale(system Language) change effect my application layouts
You can create a public class (public class Share) with static members like public static String language = "en"; You can easily access the fields of this class with using the code as Share.language in whole of your project. If you want to change the language you can set Share.language = "fa";. To reload the activity with selected language, you should place the following code before any activitie's super.onCreate(saveInstanceState); :
Locale l = new Locale(Shares.language);
Locale.setDefault(l);
Configuration config = new Configuration();
config.locale = l;
context.getApplicationContext().getResources()
.updateConfiguration(config, null);
Please note that, language can be set, if you have a folder like values-language in your /res folder.
Good luck, Hossein :)
