Phone number formatting an EditText in Android

Question

I am making a simple Address Book app (targeting 4.2) that takes name, address, city, state, zip and phone.

I want to format the phone number input as a phone number

Answer 1

//(123) 456 7890  formate set

private int textlength = 0;

public class MyPhoneTextWatcher implements TextWatcher {

    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
    }
    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {


        String text = etMobile.getText().toString();
        textlength = etMobile.getText().length();

        if (text.endsWith(" "))
            return;

        if (textlength == 1) {
            if (!text.contains("(")) {
                etMobile.setText(new StringBuilder(text).insert(text.length() - 1, "(").toString());
                etMobile.setSelection(etMobile.getText().length());
            }

        } else if (textlength == 5) {

            if (!text.contains(")")) {
                etMobile.setText(new StringBuilder(text).insert(text.length() - 1, ")").toString());
                etMobile.setSelection(etMobile.getText().length());
            }

        } else if (textlength == 6 || textlength == 10) {
            etMobile.setText(new StringBuilder(text).insert(text.length() - 1, " ").toString());
            etMobile.setSelection(etMobile.getText().length());
        }

    }
    @Override
    public void afterTextChanged(Editable editable) {
    }
}
