Databinding crashes onCreateViewHolder
from the CommonsWare Community archivesAt September 12, 2019, 1:44pm, jQrgen asked:
After moving to a single-activity app databinding crashes as follows when creating a viewHolder for a recyclerView.
The problem is that there is little information on what causes the crash (see log below).
I have tried rebuildin and invalidating gradle and android studio caches with no success.
internal class ChatListAdapter (
private val moduleInstanceId: String
) : ListAdapter<ChatItemData, ChatListAdapter.ViewHolder>(ChatItemDataDiffCallBack){
override fun onCreateViewHolder (parent: ViewGroup, viewType: Int): ViewHolder {
return ViewHolder( // NOTE: crashes here.
ItemChatBinding.inflate(
LayoutInflater.from(parent.context), parent, false
)
)
}
...
....
}
xml file the adapter is trying to inflate
