How to know whether a RecyclerView / LinearLayoutManager is scrolled to top or bottom?

by

The solution is in the layout manager.

LinearLayoutManager layoutManager = new LinearLayoutManager(this);

// Add this to your Recycler view
recyclerView.setLayoutManager(layoutManager);

// To check if at the top of recycler view
if(layoutManager.firstCompletelyVisibleItemPosition()==0){
    // Its at top
}

// To check if at the bottom of recycler view
if(layoutManager.lastCompletelyVisibleItemPosition()==data.size()-1){
    // Its at bottom
}

EDIT

In case your item size is larger than the screen use the following to detect the top event.

RecyclerView recyclerView = (RecyclerView) view;
LinearLayoutManager linearLayoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();

int pos = linearLayoutManager.findFirstVisibleItemPosition();

if(linearLayoutManager.findViewByPosition(pos).getTop()==0 && pos==0){
    return true;
}

PS: Actually, if you place the RecyclerView directly inside the SwipeRefreshview you wouldn’t need to do this
