How to remove country code , When Pick Phone Number from contacts

问题

I have doubt in that section. How to Remove country code, when I pick phone number from contact list?

Ex: +91 999999999 instead of 9999999999 or +020 9696854549 instead of 9696854549 Can any one know the answer about my question. please give solution to this problem

I attached my code and image here.

     private void contactPicked(Intent data) {
    Cursor cursor = null;
    try {
    String phoneNo = null ;
    // getData() method will have the Content Uri of the selected contact
    Uri uri = data.getData();
    //Query the content uri
    cursor = getContentResolver().query(uri, null, null, null, null);
    cursor.moveToFirst();
    // column index of the phone number
    int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER
  phoneNo = cursor.getString(phoneIndex);
   String phoneNumber = phoneNo.replaceAll(" ","");
   mobile_et.setText(phoneNumber);
} catch (Exception e) {
    e.printStackTrace();
}
}

use this function hope it will help you out:

public String phoeNumberWithOutCountryCode(String phoneNumberWithCountryCode) {
        Pattern complie = Pattern.compile(" ");
        String[] phonenUmber = complie.split(phoneNumberWithCountryCode);
        Log.e("number is", phonenUmber[1]);
        return phonenUmber[1];
    }

My English is poor, but I will try my best to answer your question.

First of all , add this line to your build.gradle

compile 'com.googlecode.libphonenumber:libphonenumber:8.7.0'

And below is a sample write by kotlin

fun deleteCountry(phone: String) : String{
    val phoneInstance = PhoneNumberUtil.getInstance()
    try {
        val phoneNumber = phoneInstance.parse(phone, null)
        return phoneNumber?.nationalNumber?.toString()?:phone
    }catch (_ : Exception) {
    }
    return phone
}

If phone number not start with a '+' followed by the country calling code then you should pass region information, for example:

val phoneNumber = phoneInstance.parse(phone, "CN")

You can use startsWith()

This method has two variants and tests if a string starts with the specified prefix beginning a specified index or by default at the beginning.

if(phoneNumber.startsWith("+"))
{
    if(phoneNumber.length()==13)
    {
    String str_getMOBILE=phoneNumber.substring(3);
    mobile_et.setText(str_getMOBILE);
    }
    else if(phoneNumber.length()==14)
    {
    String str_getMOBILE=phoneNumber.substring(4);
    mobile_et.setText(str_getMOBILE);
    }


}
else
{
 mobile_et.setText(phoneNumber);
}

It will work for all instances. You need not care about how much digit the country code is

String get_Mo = phoneNumber.substring(phoneNumber.lastIndexOf(' ')+1));

回答5:

String Trimmed = s.toString().trim();
if(Trimmed.length() > 10){
char[] number = Trimmed.toCharArray();
int extra;
int dif = Trimmed.length() - 10 ;
for(int i = dif; i < Trimmed.length() ; i++){
    extra = i-dif;
    number[extra] = number[i];
}
for (int i = 10 ; i < Trimmed.length() ; i++){
    number[i]=' ';
}
String finalNumber = String.valueOf(number);
MobileNumberET.setText(finalNumber.trim());
}

//paste this in your text change listener

Use a library https://groups.google.com/forum/?hl=en&fromgroups#!forum/libphonenumber-discuss

PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
// phone must begin with '+'
PhoneNumber numberProto = phoneUtil.parse(phone, "");
int countryCode = numberProto.getCountryCode();
} catch (NumberParseException e) {
System.err.println("NumberParseException was thrown: " + e.toString());
}

If you'd like to perform some extra function on a particular Sim on the mobile you can use some of the many methods below. Might not be a perfect solution but, I'll try my best. First get the country code programmatically :

TelephonyManager tm = (TelephonyManager) 
this.getSystemService(Context.TELEPHONY_SERVICE);
//get the country iso from sim e.g US, NG, FR etc
String countryIso = tm.getSimCountryIso().toUpperCase():
//get countrycode from refegion returns the code e.g +123, +1, +23 etc. 
Int countryCode = 
phoneNumberUtil.getInstance().getCountryCodeForRegion(countryIso);

Then you can remove it using your preferred way likeString PhoneNumber = phoneNo.replaceAll("countryCode ", "" );

I am just simply extending the answer that If you don't want to use any library then you can do it in this way. In order to match any prefix and since some countries could share partially the same prefix (for example 91 and 91-721), you add all possibilities to the regex in descending order and size.

Follow this Code:

public static String PhoneNumberWithoutCountryCode(String phoneNumberWithCountryCode){//+91 7698989898
        Pattern compile = Pattern.compile("\\+(?:998|996|995|994|993|992|977|976|975|974|973|972|971|970|968|967|966|965|964|963|962|961|960|886|880|856|855|853|852|850|692|691|690|689|688|687|686|685|683|682|681|680|679|678|677|676|675|674|673|672|670|599|598|597|595|593|592|591|590|509|508|507|506|505|504|503|502|501|500|423|421|420|389|387|386|385|383|382|381|380|379|378|377|376|375|374|373|372|371|370|359|358|357|356|355|354|353|352|351|350|299|298|297|291|290|269|268|267|266|265|264|263|262|261|260|258|257|256|255|254|253|252|251|250|249|248|246|245|244|243|242|241|240|239|238|237|236|235|234|233|232|231|230|229|228|227|226|225|224|223|222|221|220|218|216|213|212|211|98|95|94|93|92|91|90|86|84|82|81|66|65|64|63|62|61|60|58|57|56|55|54|53|52|51|49|48|47|46|45|44\\D?1624|44\\D?1534|44\\D?1481|44|43|41|40|39|36|34|33|32|31|30|27|20|7|1\\D?939|1\\D?876|1\\D?869|1\\D?868|1\\D?849|1\\D?829|1\\D?809|1\\D?787|1\\D?784|1\\D?767|1\\D?758|1\\D?721|1\\D?684|1\\D?671|1\\D?670|1\\D?664|1\\D?649|1\\D?473|1\\D?441|1\\D?345|1\\D?340|1\\D?284|1\\D?268|1\\D?264|1\\D?246|1\\D?242|1)\\D?");
        String number = phoneNumberWithCountryCode.replaceAll(compile.pattern(), "");
        //Log.e(tag, "number::_>" +  number);//OutPut::7698989898
        return number;
    }
