如何在Android中使用libphonenumber api从手机号码获取国家代码[重复]

Question

我在 android 项目中使用 libphonenumber api https://code.google.com/p/libphonenumber/，我正在使用以下代码获取国家/地区代码

PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
       PhoneNumber numberProto = phoneUtil.parse(number, "IN");
       int countryCode = numberProto.getCountryCode();
      } catch (NumberParseException e) {
         System.err.println("NumberParseException was thrown: " + e.toString());
      }

我的问题是：- -- 我有 +447870000000 这样的号码，但不知道国家/地区代码，但想从 +44 这样的号码中获取国家/地区代码，如何通过此 api 获取？

请帮帮我 在此先感谢

Answer 2

提供了一个不错的库

https://github.com/hbb20/CountryCodePickerProject

在依赖中添加

dependencies {
    implementation 'com.hbb20:ccp:2.2.0'
}

然后使用这个xml代码

<com.hbb20.CountryCodePicker
    android:id="@+id/ccp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    fbutton:ccp_contentColor="@color/appcolor"
    fbutton:ccp_textSize="@dimen/_10sdp" />

它会自动填充国家代码列表，你也可以在里面搜索。

Answer 3

如果您有一个 E164 格式的数字（在您的情况下为 +447870000000）并且您在解析器中指定国家代码 ISO，它实际上会忽略给定的 iso 代码并根据数字进行格式化。

当您提供给方法的编号是国家格式时，需要国家代码 ISO。

就您的代码 sn-p 而言，它应该可以工作。
