Usage

To use this library is very easy

• Create Form class

 private class BasicForm extends Form {
        public BasicForm() {
            super();
        }

        public BasicForm(ValidatorInterface validator) {
            super(validator);
        }

        @Override
        public void save() throws FormException {
            // implement the saving logic, you have access to
            // getValues() returns a map of where key is the name of the field and the values
        }
}

• Create form object

BasicForm form = new BasicForm();

• Add Field to FormInterface

// get the views from the layout
Spinner genderSpinner = (Spinner) editText.findViewById(R.id.gender);
EditText fName = (EditText) editText.findViewById(R.id.firstname);
EditText phone_number = (EditText) editText.findViewById(R.id.phone_number);

// add views to the form
form.addField("gender", genderSpinner);
form.addField("firstname", fName);
form.addField("phone_number", fName);

// add validation check
form.addCheck(new NotEmptyCheck(gender,"Gender cannot be blank"));
form.addCheck(new NotEmptyCheck(fName,"Firstname cannot be blank"));

• Run validation and get the values.

if(form.isValid()){
    form.getValues()// returns a map of where key is the name of the field and the values

}else{

     LinearLayout errorSpace = (LinearLayout) findViewById(R.id.error_base);
     errorSpace.removeAllViews();// clear space first

     ErrorRenderer errorRenderer = new ErrorRenderer(this, form.getValidator());
     errorRenderer.render(errorSpace);
}

• Save form values

if(form.isValid()){
    try{
        form.save() // save
    } catch (FormException e) {
        e.printStackTrace();
    }

}else{

    LinearLayout errorSpace = (LinearLayout) findViewById(R.id.error_base);
    errorSpace.removeAllViews();// clear space first

    ErrorRenderer errorRenderer = new ErrorRenderer(this, form.getValidator());
    errorRenderer.render(errorSpace);
}
