Answer 1

For the validation of Text box

1. minimum length: u can directly give the length of that text. 2. mail validation:

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

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

1. For phone number: If you want to fix length then give the length and the input type is number.
