5 years ago it looks like your problem is this
@ModelView(defaultLayout = R.layout.test_layout)
class CustomImageSliderThe layout you provide to the @ModelView annotation must have a top level component of CustomImageSlider
Also, I would not recommend using @Automodel - just use kotlin and manually specify the id, this is mentioned in the wiki.
Lastly, I would be wary of setting up your custom Image slider with a viewpager as you have. There are a host of issues with that that Epoxy's provided Carousel is designed to automatically solve. For one thing, your EpoxyImageSliderModel does not clear anything on unbind.
If you need snapping behavior of a Viewpager that can be achieved with custom SnapHelper logic

5 years ago Actually I was trying to use the suggested approach that you were provided for this issue for my problem. I tried it without the @ModelView annotation first (as it was in here) and since it throws exception, I tried to fix it by adding @ModelView and then by adding @Automodel.
In the time I was waiting for suggestion I tried many different variations including using CustomImageSlider as top view in the layout file (that you suggested above) and still same error.
I wanted the ViewPager behaviour and I achieved it with SnapHelper. Although as I need autoscroll behaviour in my slider, having it with a custom ViewPager could make its implementation easier. My problem with this costume model is not resolved but as I am not using this approach, I close the issue.

5 years ago FYI you can setup auto scrolling for a recyclerview pretty easy with something like this
class AutoScrollingController(private val target: Target) {
private val automationHandler: Handler by lazy { Handler(Looper.getMainLooper()) }
private var itemIndex: Int = 0
var isRunning: Boolean = false
private set
var isCancelled: Boolean = false
private set
interface Target {
/**
* Scroll to the given position.
* @return true if the scroll was successful, false if no more attempts should be made.
*/
fun scrollToPosition(position: Int): Boolean
}
/**
* Starts auto scrolling, if it hasn't already been started. Scrolling continues until it is canceled. Once [MAX_SCROLL_COUNT] images are
* scrolled to this loops back to the first image and continues anew.
*/
fun start() {
if (isRunning || ANIMATIONS_DISABLED) {
return
}
isCancelled = false
isRunning = true
automationHandler.postDelayed(object : Runnable {
override fun run() {
itemIndex++
// Auto scrolling can be cancelled during the target callback
if (target.scrollToPosition(itemIndex % MAX_SCROLL_COUNT) && !isCancelled) {
automationHandler.postDelayed(this, CYCLE_DELAY_MS)
} else {
cancel()
}
}
}, START_DELAY_MS)
}
fun cancel() {
isCancelled = true
isRunning = false
automationHandler.removeCallbacksAndMessages(null)
}
}

5 years ago @elihart How can I apply this AutoScrollingController to RecyclerView?
I am using a custom view to create imageSlider and I receive this error:
android.widget.FrameLayout cannot be cast to PACKAGE_NAME.epoxy.CustomImageSliderHere is my code: layout file:
test_layout.xmlCustom View class:
Epoxy Model:
Epoxy Controller (I have coded this class in java, as I couldn't use
@AutoModelin my controller class when I wrote it in kotlin, it threwAutoModel annotations must not be on private or static fieldseven though the field was public and non static)The
AdapterSliderItemBindingModel_epoxy model is generated from layout file with databinding, and I have used it inEpoxyImageSliderModelI get this error :
android.widget.FrameLayout cannot be cast to PACKAGE_NAME.epoxy.CustomImageSlider. I have checked similar issues and I used@AutoModelto generateids for models, also I have setids in controller before adding the model to controller but it didn't help.Here is the complete stack trace for error:
@elihart Can you please have a look and give some insight on this error?
