RecylerView向左/向右滑动ui问题
在我的代码中，我想实现向左/向右滑动功能
其中一项可以接受，另一项可以拒绝
从左到右快速运行，根本没有问题。您可以看到屏幕截图。
但是当我尝试从右向左显示时，我有一个问题，它什么也没显示。我只是一个白色的屏幕。在此处查看屏幕截图
我应该有这个
我可以将代码放在这里。
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);
}
}
@Override
public boolean onMove(@NonNull RecyclerView recyclerView, @NonNull RecyclerView.ViewHolder viewHolder, @NonNull RecyclerView.ViewHolder target) {
return false;
}
@Override
public void onSwiped(@NonNull RecyclerView.ViewHolder viewHolder, int direction) {
int position = viewHolder.getAdapterPosition();
mAdapter.deleteItem(position);
}
@Override
public void onChildDraw(@NonNull Canvas c, @NonNull RecyclerView recyclerView, @NonNull RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
final View foregroundView = ((DMBaseAdapter.BaseViewHolder<DriverOrderItemBinding>) viewHolder).binding.llForeground;
drawBackground(viewHolder, dX, actionState);
getDefaultUIUtil().onDraw(c, recyclerView, foregroundView, dX, dY, actionState, isCurrentlyActive);
}
@Override
public void onChildDrawOver(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {

drawBackground(viewHolder, dX, actionState);
getDefaultUIUtil().onDrawOver(c, recyclerView, foregroundView, dX, dY, actionState, isCurrentlyActive);
}
@Override
public void clearView(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {
final View rlBackground = ((DMBaseAdapter.BaseViewHolder<DriverOrderItemBinding>) viewHolder).binding.rlBackground;
final View foregroundView = ((DMBaseAdapter.BaseViewHolder<DriverOrderItemBinding>) viewHolder).binding.llForeground;
// TODO: should animate out instead. how?
rlBackground.setRight(0);
getDefaultUIUtil().clearView(foregroundView);
}
private static void drawBackground(RecyclerView.ViewHolder viewHolder, float dX, int actionState) {
final View rlBackground = ((DMBaseAdapter.BaseViewHolder<DriverOrderItemBinding>) viewHolder).binding.rlBackground;
final View rlBackground2 = ((DMBaseAdapter.BaseViewHolder<DriverOrderItemBinding>) viewHolder).binding.rlBackground2;
if (actionState == ItemTouchHelper.ACTION_STATE_SWIPE) {
//noinspection NumericCastThatLosesPrecision
if (dX > 0) {
rlBackground.setRight((int) Math.max(dX, 0));
rlBackground.setVisibility(View.VISIBLE);
rlBackground2.setVisibility(View.GONE);
// Log.d("myLogs", "1 " + dX);
} else if (dX < 0) {
rlBackground.setRight((int) Math.max((-1) * dX, 0));
// rlBackground2.setRight((int) Math.max(aaa, 0));
rlBackground.setVisibility(View.GONE);
rlBackground2.setVisibility(View.VISIBLE);
// Log.d("myLogs", "2 " + dX);
} else {
rlBackground.setVisibility(View.GONE);
rlBackground2.setVisibility(View.GONE);
// Log.d("myLogs", "0");
rlBackground.setRight((int) Math.max(dX, 0));
// rlBackground2.setRight((int) Math.max(dX, 0));
}
}
}
}
这是我的xml

我知道问题来自rlBackground.setRight((int) Math.max((-1) * dX, 0));这行。
谁能告诉我该在哪里显示我被拒绝的观点？
我尝试了很多方法。我也尝试了setLeft方法-没有结果
请有人可以帮我还是给我一个例子？
