Hi @amitysupport , When we click on Profile or MyFeed or Community page if there is any post items available we are showing an empty view (Your Feed is Empty )for few seconds . If post data is available we don’t want to show the empty view anytime . The issue is that while retrieving data from observable the UI gets updated with empty view and then it gets updated with list of data.
Could you please guide us how can we avoid this empty view. Please refer video.

sample code for updating UI:
fun setupFeedRecyclerview() {
println("second time adapter count " + adapter.itemCount)
adapter.addLoadStateListener { loadStates →
when (val refreshState = loadStates.mediator?.refresh) {
is LoadState.NotLoading → {
if (loadStates.source.refresh is LoadState.NotLoading && loadStates.append.endOfPaginationReached)
{ if(adapter.itemCount < 1 )
{
isFirstLoad = false
binding.emptyViewContainer.visibility = View.VISIBLE
binding.recyclerViewFeed.visibility = View.GONE
handleEmptyState(getEmptyView(getInflater()))
}
else{
binding.emptyViewContainer.removeAllViews()
handleLoadedState(adapter.itemCount)
}
}
binding.progressBar.visibility = View.GONE
}
is LoadState.Error → {
isFirstLoad = false
binding.progressBar.visibility = View.GONE
handleErrorState(AmityError.from(refreshState.error))
}
is LoadState.Loading → {
handleLoadingState()
}
else → {}
}
}
println(“check my data” + adapter.snapshot().items)
binding.recyclerViewFeed.adapter = adapter
binding.recyclerViewFeed.layoutManager = LinearLayoutManager(context)
getItemDecorations().forEach { binding.recyclerViewFeed.addItemDecoration(it) }
binding.recyclerViewFeed.addOnScrollListener(object : RecyclerView.OnScrollListener() {
override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
super.onScrollStateChanged(recyclerView, newState)
if (newState == SCROLL_STATE_SETTLING) {
getViewModel().sendPendingReactions()
}
}
})
adapter.registerAdapterDataObserver(object : RecyclerView.AdapterDataObserver() {
override fun onItemRangeInserted(positionStart: Int, itemCount: Int) {
super.onItemRangeInserted(positionStart, itemCount)
if (positionStart == 0) {
binding.recyclerViewFeed.smoothScrollToPosition(0)
}
}
})
// if(adapter.snapshot().items.isEmpty()){
// handleEmptyState(getEmptyView(getInflater()))
// }else{
// binding.emptyViewContainer.removeAllViews()
// handleLoadedState(adapter.itemCount)
// }
}
