Answer 1

Here By giving input type Email you are setting the keyboard of email type means "@" and "." keyword will display on key board.

the better solution is to compare the email by following function

public boolean isEmailValid(String email)
    {
         String regExpn =
             "^(([\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})$";

     CharSequence inputStr = email;

     Pattern pattern = Pattern.compile(regExpn,Pattern.CASE_INSENSITIVE);
     Matcher matcher = pattern.matcher(inputStr);

     if(matcher.matches())
        return true;
     else
        return false;
}

if this function returns true then your email address is valid otherwise not
