Я пробовал использовать CardView в ViewPager, и каждый раз, когда я прокручивал CardView влево/вправо, он переходил на следующий экран. Я хочу, чтобы карта удалила себя тогда. В настоящее время как автономные оба работают нормально, но когда я объединяю, работает только просмотр пейджера, а не закрытие карты.
Я попытался отключить ViewPager с помощью приведенного ниже кода, но этот код также отключает жесты смахивания CardView. Как я могу сделать так, чтобы только CardView имел жест, и когда вы проводите пальцем между двумя картами, тогда он должен иметь ViewPager, поскольку он не подключен к элементу карты.
Или полностью отключите ViewPager и используйте его как кнопки и включите прокрутку на CardView. Я очень ценю любую помощь. Заранее спасибо.
К вашему сведению: я пробовал android_horizontal_listview в ViewPager, и он отлично работает и точно так же.
Для ViewPager:
mPager.setOnTouchListener(new OnTouchListener()
{
@Override
public boolean onTouch(View v, MotionEvent event)
{
return true;
}
});
Для карты:
SwipeableRecyclerViewTouchListener swipeTouchListener =
new SwipeableRecyclerViewTouchListener(mRecyclerView,
new SwipeableRecyclerViewTouchListener.SwipeListener() {
@Override
public boolean canSwipe(int position) {
return true;
}
@Override
public void onDismissedBySwipeLeft(RecyclerView recyclerView, int[] reverseSortedPositions) {
for (int position : reverseSortedPositions) {
mItems.remove(position);
mAdapter.notifyItemRemoved(position);
}
mAdapter.notifyDataSetChanged();
}
@Override
public void onDismissedBySwipeRight(RecyclerView recyclerView, int[] reverseSortedPositions) {
for (int position : reverseSortedPositions) {
mItems.remove(position);
mAdapter.notifyItemRemoved(position);
}
mAdapter.notifyDataSetChanged();
}
});
mRecyclerView.addOnItemTouchListener(swipeTouchListener);
