I am using DataBinding in android and I have a custom view: CarouselView
I wrote a binding adapter for that:
@BindingAdapter("onClick")
fun setOnClick(carouselView: CarouselView, onClick: (position: Int) -> Unit) {
carouselView.setImageClickListener { position ->
onClick.run(position)
}
}
And in the xml:
<com.synnapps.carouselview.CarouselView
android:id="@+id/carouselView"
...
app:onClick="@{(p) -> vm.onAdsClicked(p)}"/>
But it does not compile. So I saw this answer in the Stackoverflow. But my problem is that I cannot use Runnable instead of kotlin hoc function because I need to pas a parameter to function.
How can I solve that?
If I may, I had the same issue (passing a param inside a HOF in a BindingAdapter) and came up with a more elegant solution. You can indeed make this work, you just need define the HOF as a variable first.
ViewModel:
val onAdsClicked = fun(position: Int) {
// Do stuff
}
XML:
<com.synnapps.carouselview.CarouselView
android:id="@+id/carouselView"
...
app:onClick="@{vm.onAdsClicked}"/>
BindingAdapter:
@BindingAdapter("onClick")
fun setOnClick(carouselView: CarouselView, onClick: (position: Int) -> Unit) {
carouselView.setImageClickListener { position ->
onClick(position)
}
}
Switching from hoc func to the the listener of this custom view worked for me:
import com.synnapps.carouselview.ImageClickListener
@BindingAdapter("onClick")
fun setOnClick(carouselView: CarouselView, imageClickListener: ImageClickListener) {
carouselView.setImageClickListener(imageClickListener)
}
