ignored validation when view is invisible or gone

@manandhar-aarya thanks a lot for your contribution. It works as expected on singular validations but It doesn't when trying to use multiple validations.

@jonoid Can you explain what you mean by singular and multiple validations? I tried using multiple validation rules (as validateEmpty, validateMinLength, validateMaxLength) in one view and it still seems to work as expected.

Oh, sorry for not being clear in my words. The fact is that there is nothing wrong with your solution. I found that the hidden view validation doesn't work by calling Validation's validate(List<ViewType> views) method.

public <ViewType extends View> boolean validate(List<ViewType> views) {
    List<View> viewWithValidations = getViewsWithValidation(views);
    return isAllViewsValid(viewWithValidations);
}

private boolean isAllViewsValid(List<View> viewWithValidations) {
    boolean allViewsValid = true;
    for (View viewWithValidation : viewWithValidations) {
        boolean viewValid = true;
        List<Rule> rules = (List) viewWithValidation.getTag(R.id.validator_rule);
        for (Rule rule : rules) {
            viewValid = viewValid && isRuleValid(rule);
            allViewsValid = allViewsValid && viewValid;
        }

        if(mode == FIELD_VALIDATION_MODE && !viewValid) {
            break;
        }
    }
    return allViewsValid;
}

But it only occurs when you by mistake includes a hidden view to be validated. In this case the hidden view should be included on the disabledViews list, so it will return true on the rule verification:

private boolean isRuleValid(Rule rule) {
    return disabledViews.contains(rule.getView()) || rule.validate();
}

The crazy thing is that it should work because if disabledViews list doesn't contain the respective view, the rule's validate() method should handle the visibility property. Maybe I'm missing something.
