如何从 Android 中的 IN、US、SG 等国家名称中获取 +91、+1、+65 等国家代码？

Question

我需要从 IN、US、SG 等国家名称中获取国家代码，如 +91、+1、+65... 使用区域设置或 android 设备中的当前位置

即假设如果设备在印度则 returns +91，如果设备在美国则 returns +1，如果设备在新加坡则 returns +65

我试了很多方法都找不到合适的解决方法

Answer 1

您可以获取国家 ID，但不能获取 +91、+1 等代码

TelephonyManager manager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
CountryID= manager.getSimCountryIso().toUpperCase();

您可以为此准备自己的数据库，您需要手动从数据库中搜索然后处理此类操作

检查here此类数据

Answer 2

我使用这个 class 将国家名称映射到 phone 前缀：

public class CountryToPhonePrefix {

private static CountryToPhonePrefix norway = new CountryToPhonePrefix("Norway ", "47");
private static ArrayList<CountryToPhonePrefix> allList;
private final String countryName;
private final String phoneNumberPrefix;

private CountryToPhonePrefix(String country, String prefix) {
    this.countryName = country;
    this.phoneNumberPrefix = prefix;
}

static synchronized List<CountryToPhonePrefix> getAll() {
    if (allList == null) {
        ArrayList<CountryToPhonePrefix> list = new ArrayList<>();
