我找到了一个可以在csv文件中获取Map的地方。check here.
另外，我把它改成了一个类，把国家代码翻译成电话前缀。这是：

public class Iso2Phone {
public static String getPhone(String code) {
    return country2phone.get(code.toUpperCase());
}
public static Map<String, String> getAll(){
    return country2phone;
}
private static Map<String, String> country2phone = new HashMap<String, String>();
static {

您可以使用Github上由Google开发人员制作的名为libphonenumber的库。例如，您可以使用以下命令获取前缀：

PhoneNumberUtil.getInstance().getCountryCodeForRegion("DE");

它也有很多有用的函数来解析电话号码。

String locale = getApplicationCOntext().getResources().getConfiguration().locale.getCountry();

我在Kotlin中简化了@oshai的答案，并添加了一些缺失的国家：

class CountryToPhonePrefix {

fun prefixFor(iso2CountryCode: String): String {
    return prefixMap[iso2CountryCode]
        ?: throw IllegalArgumentException("Unknown country code $iso2CountryCode")
}
