Issue
Basically I want my recyclerview to automatically scroll to a position where the item is not half shown. Like the one in googleplay.
I have written a code
public void scrollToVisible(){
int firstVisibleItemPosition = ((LinearLayoutManager) recyclerView.getLayoutManager()).findFirstVisibleItemPosition();
View view = recyclerView.getLayoutManager().getChildAt(0);
if (firstVisibleItemPosition > 0 && view != null) {
int offsetTop = view.getTop();
if (firstVisibleItemPosition - 1 >= 0 && adapter.getItemCount() > 0) {
((LinearLayoutManager) recyclerView.getLayoutManager()).scrollToPositionWithOffset(firstVisibleItemPosition - 1, offsetTop);
}
}
}
The problem comes next. I dont know where to put this code. I have a vague idea to put it when the recyclerview stops on scrolling but I've been searching for quite some time now and i cant find such a method. when i put it on the onScroll some unexpected behavior comes out
Solution
You may create a CustomRecyclerView extending RecyclerView
public class CustomRecyclerView extends RecyclerView {
@Override
public void onScrollStateChanged(int state) {
super.onScrollStateChanged(state);
// check if scrolling has stopped
if (state == SCROLL_STATE_IDLE) {
LinearLayoutManager linearLayoutManager = (LinearLayoutManager) getLayoutManager();
// use code here
}
}
