I am using evant/binding-collection-adapter to render the list of items. I want to scroll to a specific position when after rendering the list. Following is my code, but it's not working. any help..??
XML.
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerViewFriends"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:nestedScrollingEnabled="true"
android:visibility="@{viewModel.isProgressBarVisible ? View.GONE : View.VISIBLE}"
app:itemBinding="@{viewModel.singleItemFriendsList}"
app:items="@{viewModel.friendDataItems}" />
activity:
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
invokeTheService();
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
getBinding().recyclerViewFriends.setLayoutManager(linearLayoutManager);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
getBinding().recyclerViewFriends.scrollToPosition(getViewModel().getFriendDataItems().size()-1);
}
}, 1000);
}
ViewModel:
public final OnItemBind<FriendItemViewModel> singleItemFriendsList = new OnItemBind<FriendItemViewModel>() {
@Override
public void onItemBind(ItemBinding itemBinding, int position, FriendItemViewModel item) {
if (position == getSelectedTabListSize() - 1 && isLoadingAdded())
itemBinding.set(BR.itemViewModel, R.layout.item_progress_friends);
else
itemBinding.set(BR.itemViewModel, R.layout.friends_listing_row);
item.setItemPosition(position);
}
};
