Android 获取当前系统语言和切换系统语言

最近有需求需要切换系统语言的功能,查阅api最终搞定,代码分享如下:
1.切换语言

public void updateLanguage(Locale locale) { 
        try { 
            Object objIActMag;
            Class clzIActMag = Class.forName("android.app.IActivityManager");
            Class clzActMagNative = Class
                    .forName("android.app.ActivityManagerNative");
            //amn = ActivityManagerNative.getDefault();
            Method mtdActMagNative$getDefault = clzActMagNative
                    .getDeclaredMethod("getDefault");
            objIActMag = mtdActMagNative$getDefault.invoke(clzActMagNative);
            // objIActMag = amn.getConfiguration();
            Method mtdIActMag$getConfiguration = clzIActMag
                    .getDeclaredMethod("getConfiguration");
            Configuration config = (Configuration) mtdIActMag$getConfiguration
                    .invoke(objIActMag);
            // set the locale to the new value
            config.locale = locale;
            //持久化  config.userSetLocale = true;
            Class clzConfig = Class
                    .forName("android.content.res.Configuration");
            java.lang.reflect.Field userSetLocale = clzConfig
                    .getField("userSetLocale");
            userSetLocale.set(config, true);
            // 此处需要声明权限:android.permission.CHANGE_CONFIGURATION
            // 会重新调用 onCreate();
            Class[] clzParams = { Configuration.class};
            // objIActMag.updateConfiguration(config);
            Method mtdIActMag$updateConfiguration = clzIActMag
                    .getDeclaredMethod("updateConfiguration", clzParams);
            mtdIActMag$updateConfiguration.invoke(objIActMag, config);
            BackupManager.dataChanged("com.android.providers.settings");
        } catch (Exception e) { 
            e.printStackTrace();
        }
    }

2.系统当前语言

public String getcurlanguage() { 
        Locale locale = mContext.getApplicationContext().getResources().getConfiguration().locale;
        String language = locale.getLanguage();
        if (language.equals("zh")) { //中文
            return mContext.getResources().getString(R.string.language_chinese);
        } else if (language.equals("en")) { //英文
            return mContext.getResources().getString(R.string.language_english);
        } else { 
            return mContext.getResources().getString(R.string.language_chinese);
        }
    }

这就是全部代码了 仅供参考
