Can someone explain what getItemCount method in RecyclerView.LayoutManager return?

Question

The documentation says the following about getItemCount():

Returns the number of items in the adapter bound to the parent RecyclerView. Note that this number is not necessarily equal to State#getItemCount().

So, does it return all the items in the adapter or the items that are visible on the screen? I don't get it. Can someone explain this method?

Answer 1

getItemCount() - returns The number of items currently available in adapter

• This method returns the size of the collection that contains the items we want to display.

  @Override
  public int getItemCount() {
      return models.size();
  }
  

• It returns The number of items currently available in adapter.

Reference:

• getItemCount()

• More about layout manager and getItemCount()

Answer 2

It returns the size of all the items in the adapter not only the size of visible items. In simple term, getItemCount() returns the size for the whole adapter.

Answer 3

The getItemCount() method returns the number of list items.The number of items this adapter is adapting.

Reference Code :

ArrayList<Games> list;

    public int getItemCount() {
         return list.size();
    }

The getItemCount() method is return the number of items in the collection you're adapting, in above case list, which is just an array of Game objects. Arrays have a property that allows you to get their length which is all you need to return.

Answer 4

getitemCount() return how many items you want to show in the recyclerView
