How to check and validate , given editext is phone number or mobile number?

Question

In my app login using mobile number or phone number in single edittext. if we give digits it check valid phone number else if we give character(alphabet) check it is valid email address.

Note : check both email and phone number in single edit text.

Here java code,

if (username.getText().toString().length() == 0) {
                erroredit(username, getResources().getString(R.string.login_label_alert_username));
            } else if (!isValidEmail(username.getText().toString().replace(" ","").trim())) {
                erroredit(username, getResources().getString(R.string.login_label_alert_email_invalid));
            } else if (!isValidmobilenumber(username.getText().toString().replace(" ","").trim())) {
                erroredit(username, getResources().getString(R.string.register_label_alert_phoneNo));
            }
            else if (password.getText().toString().length() == 0) {
                erroredit(password, getResources().getString(R.string.login_label_alert_password));
            }

Try this

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String data = editemail.getText().toString().trim();
            String pass = edtPass.getText().toString().trim();

            boolean flag = false;

            if (TextUtils.isEmpty(pass)) {
                edtPass.setError("Enter password");
                //edtPass.requestFocus();
            }else {

            }

            if (TextUtils.isEmpty(data)) {
                editemail.setError("Enter Data");
            } else {
                if (data.matches("[0-9]+")) {
                    if (data.length() < 10 && data.length() > 10) {
                        editemail.setError("Please Enter valid phone number");
                        editemail.requestFocus();
                    } else {
                        flag = true;
                    }
                } else {
                    if (!android.util.Patterns.EMAIL_ADDRESS.matcher(data).matches()) {
                        editemail.setError("Please Enter valid email");
                        editemail.requestFocus();
                    }else {
                        flag = true;
                    }
                }
            }

            if(!TextUtils.isEmpty(pass)&&flag){
                Toast.makeText(MainActivity.this, "pass", Toast.LENGTH_SHORT).show();
            }
        }
    });
