How do i use Ratifier?

To use Ratifier as your form validator, use RatifierEditText and Ratifier will handle everything. Example for Email:

And to validate use
Ratifier.Valid result = Ratifier.getValidity(this);
if (result.isValid()) { // Form is valid
    Toast.makeText(this, "Email is valid", Toast.LENGTH_SHORT).show();
} else { // Form is not valid
    Toast.makeText(this, ratify.getErrorMsg(), Toast.LENGTH_SHORT).show();


Following are the attributes used by RatifierEditText for validation

| Attribute | Descripion | | ------ | ------ | | required | If field is required for validation or not (true/false) | | emptyMessage | Message for empty field | | invalidMessage | Message for invalid field | | inputType | textEmailAddress, textPassword for email and password validation. Ratifier will validate for match password also if two fields with inputType textPassword are provided. In case of invalidation, Invalid message must be provided | | minCharacters | Minimum characters. Invalid message must be provided for this. | | regex | For validation using regex like valid phone number, credit card, IP address etc. Invalid message must be provided for this. |

Values can be set from activity by:

ratifierEditText.setEmptyMessage("Filed is empty");
ratifierEditText.setInvalidMessage("Password should be greater than 4 characters");
ratifierEditText.setRegex("/^(\+\d{1,3}[- ]?)?\d{10}$/"); // Regex for valid mobile number
Remember to give regex from Strings.xml

Ratifier Results

Ratifier validity result will give us:

 Ratifier.Valid result = Ratifier.getValidity(this);
 boolean isValid = result.isValid(); // boolean - If the result is valid or not.
 String errorMessage = result.getErrorMsg(); // String - Error Message if result is not valid.
 RatifierEditText ratifierEditText = result.getField(); // Will return RatifierEditText which is not valid.
- isValid() - boolean - If the result is valid or not. - getErrorMsg() - String - Error Message if result is not valid. - getField() - RatifierEditText - Will return RatifierEditText which is not valid

Some Regex examples:

Mobile Number: /^(+\d{1,3}[- ]?)?\d{10}$/

Email Address: /^([a-z0-9_.-]+)@([\da-z.-]+).([a-z.]{2,6})$/

URL: /^(https?:\/\/)?([\da-z.-]+).([a-z.]{2,6})([\/\w .-])\/?$/

IP Address:/^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/
