The following regex expression will help you to determine if there is a valid e-mail address or not in your edit text.
public static boolean isValid(String email) { String expression = "^[\\w\\.-]+@([\\w\\-]+\\.)+[A-Z]{2,4}$"; CharSequence inputStr = email; Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE); Matcher matcher = pattern.matcher(inputStr); if (matcher.matches()) { return true; } else{ return false; } }
