我正在使用CardStackViewyuyakaido的图书馆，但我似乎无法完成这项CardStackListener工作。这是图书馆的链接：https :
//github.com/yuyakaido/CardStackView#callbacks
我已经将它实施到我的Fragment.
public class PendingFragment extends Fragment implements CardStackListener{
private CardStackLayoutManager manager;
private CardStackView cardStackView;
@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View mView = inflater.inflate(R.layout.fragment_pending, container, false);
manager = new CardStackLayoutManager(getActivity());
manager.setStackFrom(StackFrom.Top);
manager.setVisibleCount(3);
manager.setCanScrollVertical(false);
cardStackView = mView.findViewById(R.id.pendingList_cardStackView);
cardStackView.setLayoutManager(manager);
}
@Override
public void onCardDragging(Direction direction, float ratio) {
}
@Override
public void onCardSwiped(Direction direction) {
Log.e("PendingFragment", "onCardSwiped: " + direction );
if(direction == Direction.Right){
Toast.makeText(getActivity(), "Accepted", Toast.LENGTH_SHORT).show(); …
