Answer 1

在PhoneNumberUtil类中尝试一下：

package com.google.i18n.phonenumbers;

public static boolean isNumberValid(String countryCode, String phNumber) {
    if (TextUtils.isEmpty(countryCode)) {// Country code could not be empty
        return false;
    }
    if (phNumber.length() < 6) {        // Phone number should be at least 6 digits
        return false;
    }
    boolean resultPattern = Patterns.PHONE.matcher(phNumber).matches();
    if (!resultPattern) {
        return false;
    }

    PhoneNumberUtil phoneNumberUtil = PhoneNumberUtil.getInstance();
    String isoCode = phoneNumberUtil.getRegionCodeForCountryCode(Integer.parseInt(countryCode));
    Phonenumber.PhoneNumber phoneNumber = null;
    try {
        phoneNumber = phoneNumberUtil.parse(phNumber, isoCode);
    } catch (NumberParseException e) {
        return false;
    }

    return phoneNumberUtil.isValidNumber(phoneNumber);
}

其中countryCode是一个国家的拨号代码: 33代表法国，34代表西班牙等等...

您可以检查number是否以所需的值开头，例如： :

String mob = mobile_number.getText().toString();

if(mob.startsWith("010") || mob.startsWith("011") || mob.startWith("012")){

      //todo your logic here 

  }
