The android.widget.ListView class is a predefined class in the Android SDK that displays a list of items based on an adapter. One of its useful methods is getHeaderViewsCount(), which returns the number of header views currently in the list.
To use this method, we first need to get an instance of the ListView class and set its adapter:
Now we can call getHeaderViewsCount() on this instance to get the number of header views in the list:
int headerCount = listView.getHeaderViewsCount();
This can be helpful, for example, if we want to check if there are header views in the list so that we can properly handle their visibility, or if we want to add more header views based on the current count.
The package library for this method is android.widget.
