Android中多语言设置_build configuration language

Demo效果图

Demo中主要设置了三种情况：跟随系统、简体中文和英文具体步骤如下：
一、在资源文件中建立多语言环境的资源文件，具体步骤可参考以下链接：
https://blog.csdn.net/MakerCloud/article/details/83146600
二、新建工具类MultiLanguageUtils.java，

public class MultiLanguageUtils {
    /**
     * Todo 更新应用语言
     * @param context
     * @param locale
     */
    public static void setAppLanguage(Context context, Locale locale) {
        Resources resources = context.getResources();
        DisplayMetrics metrics = resources.getDisplayMetrics();
        Configuration configuration = resources.getConfiguration();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            configuration.setLocale(locale);
        } else {
            configuration.locale = locale;
        }
        resources.updateConfiguration(configuration, metrics);
    }
    /**
     * 判断系统中和app中的多语言信息是否相同
     */
    public static boolean isSameWithSystem(Context context) {
        String mTmpLanguage = null;
        String appLanguage = (String) SPUtils.get(context, Constant.SP.LANGUAGE, "");
        String systemLanguage = Locale.getDefault().getLanguage();
        if("en".equals(systemLanguage)){
            mTmpLanguage = "English";
        } else if("zh".equals(systemLanguage)){
            mTmpLanguage = "简体中文";
        }
        if (mTmpLanguage.equals(appLanguage)) {
            return true;
        } else {
            return false;
        }
    }
    /**
     * 保存多语言信息到sp中
     */
    public static void saveLanguageSetting(Context context, Locale locale) {
        SPUtils.put(context, Constant.SP.LANGUAGE,locale.getLanguage());
        SPUtils.put(context, Constant.SP.COUNTRY,locale.getCountry());
    }
    /**
     * 获取应用语言
     */
    public static Locale getAppLocale(Context context){
        Locale local;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            local =context.getResources().getConfiguration().getLocales().get(0);
        } else {
            local =context.getResources().getConfiguration().locale;
        }
        return local;
    }
    /**
     * 获取系统语言
     */
    public static LocaleListCompat getSystemLanguage1(){
        Configuration configuration = Resources.getSystem().getConfiguration();
        LocaleListCompat locales = ConfigurationCompat.getLocales(configuration);
        return locales;
    }
    public static Locale getSystemLanguage(){
        Locale mLocale = null;
        String systemLanguage = Locale.getDefault().getLanguage();
        if("en".equals(systemLanguage)){
            mLocale = Locale.ENGLISH;
        } else if("zh".equals(systemLanguage)){
            mLocale = Locale.SIMPLIFIED_CHINESE;
        }
        return mLocale;
    }
    //注册Activity生命周期监听回调，此部分一定加上，因为有些版本不加的话多语言切换不回来
    //registerActivityLifecycleCallbacks(callbacks);
    public static  Application.ActivityLifecycleCallbacks callbacks = new Application.ActivityLifecycleCa
