android - 如何更改另一个应用程序的语言环境？

Question

我可以使用以下代码更改我的应用程序的语言环境：

public static void setLocale(Locale locale) 
{
    Locale.setDefault(locale);
    Configuration appConfig = new Configuration();
    appConfig.locale = locale;
    App.context().getResources().updateConfiguration
            (appConfig,App.context().getResources().getDisplayMetrics());
} 

但是如何使用任何其他应用程序来做到这一点？

完毕！！！

我正在与其他用户分享我的代码！它采用英语语言环境中当前活动应用程序的名称：

public static void setLocale(Locale locale, String packageName){
    try{
        Context myAppContext = App.context();
        Context otherAppContext = myAppContext.createPackageContext(packageName, myAppContext.CONTEXT_IGNORE_SECURITY);         
        Locale.setDefault(locale);
        Configuration appConfig = new Configuration();
        appConfig.locale = locale;
        otherAppContext.getResources().updateConfiguration(appConfig, App.context().getResources().getDisplayMetrics());
    }catch(Throwable t){
       History.Error(t);
    }
} 

public static String getActive(){
    try{        
        PackageManager pm = App.context().getPackageManager();
        ActivityManager am = (ActivityManager) App.context().getSystemService(App.context().ACTIVITY_SERVICE);
        RunningTaskInfo taskInfo = am.getRunningTasks(1).get(0);    // The first in the list of RunningTasks is always the foreground task.
        String packageName = taskInfo.topActivity.getPackageName();         
        setLocale(new Locale("en-US"), packageName);        
        PackageInfo appInfo = pm.getPackageInfo(packageName, 0);
        String label = appInfo.applicationInfo.loadLabel(pm).toString();
        App.Toast(label);       
        return  label;
    }catch (Throwable t){
        History.Error(t);
    }
    return "???";
}
