Android App多语言国际化开发关键代码解析

/**
     * 如果不是英文、简体中文、繁体中文，默认返回简体中文
     *
     * @return
     */
    private Locale getLanguageLocale() {
        int languageType = CommSharedUtil.getInstance(mContext).getInt(MultiLanguageUtil.SAVE_LANGUAGE, 0);
        if (languageType == LanguageType.LANGUAGE_FOLLOW_SYSTEM) {
            Locale sysLocale= getSysLocale();
            return sysLocale;
        } else if (languageType == LanguageType.LANGUAGE_EN) {
            return Locale.ENGLISH;
        } else if (languageType == LanguageType.LANGUAGE_CHINESE_SIMPLIFIED) {
            return Locale.SIMPLIFIED_CHINESE;
        } else if (languageType == LanguageType.LANGUAGE_CHINESE_TRADITIONAL) {
            return Locale.TRADITIONAL_CHINESE;
        }
        getSystemLanguage(getSysLocale());
        Log.e(TAG, "getLanguageLocale" + languageType + languageType);
        return Locale.SIMPLIFIED_CHINESE;
    }

getLanguageLocale()方法通过 CommSharedUtil.getInstance(mContext).getInt(MultiLanguageUtil.SAVE_LANGUAGE, 0);方法获取languageType的值，如果没有则定义的值置为0，通过对获取的值与预先定义的各国语言的值做对比，然后返回各国语言的Locale。

/**
     * 设置语言
     */
    public void setConfiguration() {
        Locale targetLocale = getLanguageLocale();
        Configuration configuration = mContext.getResources().getConfiguration();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            configuration.setLocale(targetLocale);
        } else {
            configuration.locale = targetLocale;
        }
            Resources resources = mContext.getResources();
            DisplayMetrics dm = resources.getDisplayMetrics();
            resources.updateConfiguration(configuration, dm);//语言更换生效的代码!
    }

setConfiguration()方法通过调用getLanguageLocale()方法获取当前切换语言的Locale，然后通过Configuration对象设置到当前Locale中，通过 resources.updateConfiguration(configuration, dm);更新语言使之生效。
