В моем коде я хочу реализовать функцию пролистывания влево / вправо
Один из размахов должен быть принят, другой - отклонен
Свифт слева направо работает отлично, никаких проблем вообще нет. Вы можете увидеть скриншот.
Но когда я пытаюсь показать справа налево, у меня возникает проблема, она ничего не показывает. У меня просто белый экран. Смотрите скриншот здесь
Ожидается, что это будет
Я могу поставить свой код здесь.
public class SwipeToDeleteCallback extends ItemTouchHelper.SimpleCallback {
private DriverOrderAdapter mAdapter;
public SwipeToDeleteCallback(final DriverOrderAdapter adapter) {
super(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT);
mAdapter = adapter;
}
@Override
public void onSelectedChanged(RecyclerView.ViewHolder viewHolder, int actionState) {
if (viewHolder != null) {
final View foregroundView = ((DMBaseAdapter.BaseViewHolder<DriverOrderItemBinding>) viewHolder).binding.llForeground;
getDefaultUIUtil().onSelected(foregroundView);
}

Я знаю, что проблема возникает из rlBackground.setRight((int) Math.max((-1) * dX, 0)); этой строки.
Может кто-нибудь сказать мне, что я должен тут же показать мой отклоненный вид?
Я много пробовал. Я пробовал также setLeft метод - без результата
Пожалуйста, кто-нибудь может мне помочь или привести пример?
