将da-DK转换为丹麦(丹麦)等 [英] Convert da-DK to Danish (Denmark) etc

问题描述

如何将语言环境ID转换为Java中的显示语言和国家/地区.例如，我有一个使用以下格式的语言环境列表:"da-DK"，我希望它们全部显示为丹麦语(丹麦)".

到目前为止，这是我的代码:

  public void getAvailableLocales(){systemLanguages = Resources.getSystem().getAssets().getLocales();Arrays.sort(systemLanguages);for(int i = 0; i< systemLanguages.length; i ++){字符串sL = systemLanguages [i];Locale loc =新的Locale(sL);字符串locDisplayResults = loc.getDisplayName();语言列表.add(新语言(locDisplayResults));recyclerAdapter.notifyDataSetChanged();}} 

不幸的是，getDisplayName()仅适用于该语言只有两个字母的情况，例如"ar"表示阿拉伯".它使"ar-EG"保持不变.

解决方案

使用 Locale.forLanguageTag(sL)代替使用 new Locale(sL).>

How do I convert locale ids into display languages and countries in Java. For instance, I have a list of locales in this format: "da-DK" and I want them all to show as "Danish (Denmark)".

Here is my code so far:

    public void getAvailableLocales() {
    systemLanguages = Resources.getSystem().getAssets().getLocales();
    Arrays.sort(systemLanguages);
    for (int i = 0; i < systemLanguages.length; i++) {
        String sL = systemLanguages[i];
        Locale loc = new Locale(sL);
        String locDisplayResults = loc.getDisplayName();
        languagesList.add(new Languages(locDisplayResults));
        recyclerAdapter.notifyDataSetChanged();
    }
}

Unfortunately, getDisplayName() is only working for cases where there is just two letters for the language, such as "ar" for "Arabic". It leaves "ar-EG" untouched.

解决方案

Instead of using new Locale(sL), use Locale.forLanguageTag(sL).
