在Android中将电话号码格式化为E164格式 [英] Formatting phone number to E164 format in Android

问题描述

我想将设备中的每个电话号码都转换为E164格式.因此，我在下面使用了开源.

I want convert every phone number from conatct in device to E164 format. So, I used opensource below.

libphonenumber

所以我像这里一样使用它.

So I used it like here.

Phonenumber.PhoneNumber formattedNumber = null;
String formatted = null;

try {
    formattedNumber = phoneUtil.parse(phoneNumber, "KR");
    formatted = phoneUtil.format(formattedNumber,PhoneNumberUtil.PhoneNumberFormat.E164);

    if (StringUtils.isEmpty(formatted) == false && formatted.length() > 0 && StringUtils.isEmpty(name) == false && name.length() > 0) {
        listName.add(name);
        listPhoneNumber.add(formatted);
    }
} catch (NumberParseException e) {
    continue;
}

我读到从4.0开始，Android框架就使用了这个库.

And I read that this library is used by the Android framework since 4.0.

Java版本已针对在智能手机上运行进行了优化，并且从4.0开始就被Android框架使用(冰淇淋三明治).

The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich).

我想从Android SDK中使用它.所以我找到了.Android SDK提供了此 PhoneNumberUtils

I want to use this from Android SDK. So I found this. Android SDK provides this PhoneNumberUtils .

有一个功能

formatNumberToE164(字符串phoneNumber，字符串defaultCountryIso)

formatNumberToE164(String phoneNumber, String defaultCountryIso)

它真的很容易使用.但此功能的API级别为21.

It's really easy to use. but API level of this function is 21.

所以我的问题是..如何在API Level 14(ICS)〜21下使用PhoneNumberUtils将电话号码转换为E164?

So My question is..How can I use PhoneNumberUtils to convert phonenumber to E164 under API Level 14(ICS) ~ 21?

谢谢.！

推荐答案

问题是 PhoneNumberUtils.formatNumberToE164(...)在较旧的设备上不可用，PhoneNumberUtils中没有其他功能可以一样的工作.

The problem is PhoneNumberUtils.formatNumberToE164(...) is not available on older devices and there's nothing else in PhoneNumberUtils that does the same job.

我建议使用PhoneNumberUtils(如果可用)，并在较旧的设备上使用libphonenumber，例如:

I'd suggest using PhoneNumberUtils when available and libphonenumber on older devices, for example:

public String formatE164Number(String countryCode, String phNum) {

    String e164Number;
    if (TextUtils.isEmpty(countryCode)) {
        e164Number = phNum;
    } else {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            e164Number = PhoneNumberUtils.formatNumberToE164(phNum, countryCode);
        } else {
            try {
                PhoneNumberUtil instance = PhoneNumberUtil.getInstance();
                Phonenumber.PhoneNumber phoneNumber = instance.parse(phNum, countryCode);
                e164Number = instance.format(phoneNumber, PhoneNumberUtil.PhoneNumberFormat.E164);

            } catch (NumberParseException e) {
                Log.e(TAG, "Caught: " + e.getMessage(), e);
                e164Number = phNum;
            }
        }
    }

    return e164Number;
}
