this code worked for me perfectly. after your suggestions i tried it.

if(isEmailValid(loginname)){ Toast.makeText(getApplicationContext(), "Email", Toast.LENGTH_LONG).show(); }else if(isValidMobileNumber(loginname)){ Toast.makeText(getApplicationContext(), "mobileNo", Toast.LENGTH_LONG).show(); }else{ Toast.makeText(getApplicationContext(), "Enter Email or Mobile No", Toast.LENGTH_LONG).show(); }

Answer 1

Try for Email

boolean isEmailValid(CharSequence email) {
 return android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches();
}

if your Edittext value return true than its Email else Mobile number

Answer 2

You can use this to check whether the input is an email or not:

 public static boolean isEmailValid(CharSequence email) {
        return android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches();
    }

Answer 3

By These two methods I solved this problem

public static boolean isPhoneNumberValid(String phoneNoWithConCode, String countryCode)
    {
        PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
        try
        {
            Phonenumber.PhoneNumber numberProto = phoneUtil.parse(phoneNoWithConCode, countryCode);
            return phoneUtil.isValidNumber(numberProto);
        }
        catch (NumberParseException e)
        {
            System.err.println("NumberParseException was thrown: " + e.toString());
        }
        return false;
    }

public static boolean isEmailValid(String email){
    return Patterns.EMAIL_ADDRESS.matcher(email).matches();
}

call these two methods one by one like

if(isPhoneNumberValid(.. , ..))
{
   //write your mobile no logic here
}else if(isEmailValid(..)
{
  //write you email logic here
}

Answer 4

First of all getText from editText and set proper validations for checking email and mobile number like below:

  email=edt_email.getText().toString();
  if (!isValidEmail(email)) 
  {
        // your code
  }

  private boolean isValidEmail(String email) {
        String EMAIL_PATTERN = "^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"
                + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";

        Pattern pattern = Pattern.compile(EMAIL_PATTERN);
        Matcher matcher = pattern.matcher(email);
        return matcher.matches();
    }

    private boolean isValidPhone(String pass) {
        return pass != null && pass.length() == 10;
    }

Answer 5

here are what I use in my project

private static boolean isValidPhoneNumber(String mobile) {
        String regEx = "^[0-9]{11,12}$";
        return mobile.matches(regEx);
    }

private boolean isValidEmaillId(String email){

        return Pattern.compile("^(([\\w-]+\\.)+[\\w-]+|([a-zA-Z]{1}|[\\w-]{2,}))@"
                + "((([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\.([0-1]?"
                + "[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\."
                + "([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\.([0-1]?"
                + "[0-9]{1,2}|25[0-5]|2[0-4][0-9])){1}|"
                + "([a-zA-Z]+[\\w-]+\\.)+[a-zA-Z]{2,4})$").matcher(email).matches();
    }

you can use if else logic to it to validate mobile or email in your activity
