android - How to change language setting of the whole system in android without Intent?

Question

I'm trying to change the language of the whole system of Android Phone on my application, cause our goal is to customized a Settings application.

I've tried this, but didn't work:

Configuration conf = Resources.getSystem().getConfiguration();

conf.locale = toSet;  //toSet is a Locale which I want to set to the system

conf.setToDefaults();

the other try didn't work either:

Locale.setDefault(toSet)

There are ways to change the language of application, but not systems.

Is there any ways that I can reach the goal? Will getting the root permissions works for me? Or is there any ways to modify the UI interface of the Intent-Activity?

I've found that, in the source code, "platform/packages/apps/Settings/src/com/android/settings/LocalePicker.java", "com.android.internal.app.LocalePicker" might help, and in the "platform/frameworks/base/core/java/com/android/internal/app", there is a function which named "updateLocale", I guess it might help, but the class such as "IActivityManager" cause compile error in the Eclipse.

Does anyone have any ideas? Thanks!

尝试这个

String languageToLoad = "zh";  
Locale locale = new Locale(languageToLoad);  
Locale.setDefault(locale);  
Configuration config = new Configuration();  
config.locale = locale;  
getBaseContext().getResources().updateConfiguration(config, null);
