Change language settings (locale) for the device

I know it's possible to have multiple languages in a single application through the res/string and depending on Locale. Here is a case (ANDROID) controling the user language

Now how can I change the language in the phone ? Like I'd do by Menu > Settings > Language & Keyboard > Select locale > languages

Is there some real code to access to these settings ? Or should I create intent for a shortcut to the language settings. Please post some code

Edit : With Locale class developer.android.com/intl/fr/reference/java/util/Locale.html

The constructor is at least Locale(String language) The input is language. How can you retrieve the current language used on the device ?

Solution 1:

Not sure about setting it directly from the app, but if you want to send the user there to change it themselves, try this:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.settings", "com.android.settings.LanguageSettings");            
startActivity(intent);

Solution 2:

There is another way to open system settings to change the language:

Intent i = new Intent( android.provider.Settings.ACTION_LOCALE_SETTINGS );
startActivity( i );

It shows just the list of languages, and when you choose one - it changes the language on the device.

Solution 3:

I found another answer to my own question. There is an open source code project code.google.com/p/languagepickerwidget It's recreating a ListActivity to display and pick the languages.

Jim , your solution is much simple and exactly what I needed. It's a shorcut to the settings. Immediately after you published, I uploaded an app called "raygional" on the market. If I could (I only have 6 points) I'd make your answer useful.

There is another way to see the processes and intents. On the emulator go to Menu > Dev Tools > Development Settings > and click on Show running processes
