Form element set to visible = false still appears about kformmaster HOT 10 CLOSED

When you are logging the elements can you also check if itemView is null or not? Are you looping through the elements after the form has been rendered and displayed or before? My only guess is that itemView is null and cannot set visibility = View.GONE for that element. Which kind of form element is it?

from kformmaster.

Its a FormMultiLioneEditTextElement.

I am looping through after being displayed.

ItemView is NOT null and I can loop through the code that sets visibility to GONE (BaseFormElement line 239).

I think it might be the cache size then. Are you using addFormElements() to add form elements? If not, you should call setItems() after you modify the elements list. This will make sure the cache size is correct and notifyDataSetChanged is called.

So I call FormBuilder with just the activity (it used to have automeasure but thats gone) like this:

formBuilder = FormBuildHelper(activity!!)
formBuilder.attachRecyclerView(activity!!, recyclerView)

then I loop through my questions, creating elements as I go and then add them:

formBuilder.addFormElements(elements)

Apart from the first question, I make all of them visible = false. Then, as they answer questions I can check the answer and decide which elements to make visible.

The issue is changes to previously answered questions need questions after it to be made invisible again (because answering questions differently might mean making other questions visible).

So, based on your comment I tried this:

when (formElement) {
                is FormPickerDropDownElement -> formElement.setVisible(false)
                is FormMultiLineEditTextElement -> {
                    formElement.setVisible(false)
                }
            }
            formBuilder.setItems()

that made no difference. Any ideas?

Could it be that the field has focus? https://stackoverflow.com/a/28467157/4056401

Call currentFocus?.clearFocus() before your loop to hide the elements.

On what class?

from kformmaster.

when (formElement) {
                is FormPickerDropDownElement -> {
                    formElement.editView?.clearFocus()
                    formElement.setVisible(false)}
                is FormMultiLineEditTextElement -> {
                    formElement.editView?.clearFocus()
                    formElement.setVisible(false)
                }
            }

didn't work (also tried itemView which returns a view)

from kformmaster.

Hmm. I really don't know. Seems like an Android problem. Caching the RecylerView should have resolved most of the weirdness for each dynamic view in the list.

from kformmaster.

Caching is the default anyway?

from kformmaster.

Yes. But apparently it does not solve all of the issues with using a RecylerView for a form.
