How do I separate a country code from a phone number in Android?

I have an XML list of country codes and their corresponding countries ready to use, but first I need to separate them from the phone numbers. Is there an easy way to do this in the Android API?

you can split your mobile number by checking is started with "+" sign and Phone number should have length 10.

void splitMobilenumberMethod(){
    String phoneNumb = MOBILE_NUMBER_TO_SPLIT;
    String ext = "", phoneN = "";
    if (phoneNumb.startsWith("+") || phoneNumb.length() > 10) {
        ext=phoneNumb.substring(0, 3);
        phoneN=phoneNumb.substring(3);
     } else {
        ext = "";
        phoneN = phoneNumb;
     }
     showSelectedPhoneDialog(ext, phoneN);
}


void showSelectedPhoneDialog(String ext, String phone) {
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);
    alertDialog.setTitle("Verify Phone Number");
    LinearLayout layout = new LinearLayout(context);
    layout.setOrientation(LinearLayout.HORIZONTAL);
    layout.setGravity(View.TEXT_ALIGNMENT_CENTER);
    final EditText extEdit = new EditText(context);
    final EditText phoneEdit = new EditText(context);
    extEdit.setHint("Country");
    phoneEdit.setHint("Mobile Number");
    layout.addView(extEdit);
    layout.addView(phoneEdit);
    extEdit.setText(ext);
    phoneEdit.setText(phone);
    alertDialog.setView(layout);

    alertDialog.setIcon(R.drawable.ic_message);
    alertDialog.setPositiveButton("Done", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            // do if split is correct or after make it corrent manually by user
        }
    });
    alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {

            dialog.cancel();
        }
    });

    alertDialog.show();
}

I've used ridsatrio's answer with an older question here

I'm getting the country code out of the string array below it with the following class:

import android.widget.TextView;

/**
 * Created by Friso on 14/11/21.
 */
public final class PhoneFunctions {
    private static PhoneFunctions instance;

    private PhoneFunctions(){}

    public static PhoneFunctions getInstance() {
        if (instance == null) {
            instance = new PhoneFunctions();
        }

        return instance;
    }

    public String getCountry(String[] argStringArray, TextView argText){
        String country="";

        if (argText.getText().toString().length() >= 4){
            for(int i=0;i<argStringArray.length;i++){
                String[] g=argStringArray[i].split(",");
                if(g[0].equals(getFirstFourChar(argText))){
                    country=g[1];
                    break;
                }
                if (g[0].equals(getFirstThreeChar(argText))){
                    country=g[1];
                    break;
                }
                if (g[0].equals(getFirstTwoChar(argText))){
                    country=g[1];
                    break;
                }
            }
        }

        return country;
    }

    public String getFirstFourChar(TextView argText){
        String threeChar;
        String text = argText.getText().toString();
        threeChar = text.substring(0,4);

        return threeChar;
    }

    public String getFirstThreeChar(TextView argText){
        String twoChar;
        String text = argText.getText().toString();
        twoChar = text.substring(0,3);

        return twoChar;
    }

    public String getFirstTwoChar(TextView argText){
        String oneChar;
        String text = argText.getText().toString();
        oneChar = text.substring(0,2);

        return oneChar;
    }
}

The country codes consist of 1-3 numbers and because this app had to have + string at the beginning of the phone number I thought it faster to just add a + to codes in the string array that I'm comparing to instead of adding more code to separate the +.

Java's String.substring() might be useful for this use-case:

yourString.substring(int beginIndex, int endIndex);

You might have to take out the XML list first, substring the first 3 numbers of your user's input, then compare it with the list's entries.
