在具有滑动操作的垂直回收视图中处理水平回收视图的滚动

Question

以下是主要回收站视图中项目的一部分的屏幕截图。浅绿色瓷砖是主回收器视图内的辅助水平回收器视图。主回收器视图具有要删除的滑动操作（也部分指示）。问题在于，每当用户滚动辅助回收器视图时，就会触发滑动操作。

预期的结果是，只要用户在二级水平回收器视图之外的任何地方滑动，就会触发滑动动作，只要用户滚动任何水平回收器视图项，就会触发滚动动作。

这是我为回收者视图触发滑动操作的地方：

SwipeToDeleteCallback swipeToDeleteCallback = new SwipeToDeleteCallback(context) {
            @Override
            public void onSwiped(@NonNull RecyclerView.ViewHolder viewHolder, int i) {
                final int position = viewHolder.getAbsoluteAdapterPosition();
                adapter.removePlan(position);
            }
        };
    ItemTouchHelper itemTouchhelper = new ItemTouchHelper(swipeToDeleteCallback);
    itemTouchhelper.attachToRecyclerView(recyclerview);

这是滑动触摸辅助回调：

    Context mContext;
    private final Paint mClearPaint;
    private final ColorDrawable mBackground;
    private final int backgroundColor;
    private final Drawable deleteDrawable;
    private final int intrinsicHeight;

    SwipeToDeleteCallback(Context context) {
        mContext = context;
        mBackground = new ColorDrawable();
        backgroundColor = ContextCompat.getColor(context, R.color.fullWhite);
        mClearPaint = new Paint();
        mClearPaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.CLEAR));
        deleteDrawable = ContextCompat.getDrawable(mContext, R.drawable.icon_delete);
        intrinsicHeight = 240;
    }

    @Override
    public int getMovementFlags(@NonNull RecyclerView recyclerView, @NonNull RecyclerView.ViewHolder viewHolder) {
        return makeMovementFlags(0, ItemTouchHelper.LEFT);
    }

    @Override
    public boolean onMove(@NonNull RecyclerView recyclerView, @NonNull RecyclerView.ViewHolder viewHolder, @NonNull RecyclerView.ViewHolder viewHolder1) {
        return false;
    }

    @Override
    public void onChildDraw(@NonNull Canvas c, @NonNull RecyclerView recyclerView, @NonNull RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
        super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);

        View itemView = viewHolder.itemView;
        int itemHeight = itemView.getHeight();

        boolean isCancelled = dX == 0 && !isCurrentlyActive;

        if (isCancelled) {
            clearCanvas(c, itemView.getRight() + dX, (float) itemView.getTop(), (float) itemView.getRight(), (float) itemView.getBottom());
            super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
            return;
        }

        mBackground.setColor(backgroundColor);
        mBackground.setBounds(itemView.getRight() + (int) dX, itemView.getTop(), itemView.getRight(), itemView.getBottom());
        mBackground.draw(c);
        deleteDrawable.setTint(Color.RED);

        int deleteIconTop = itemView.getTop() + (itemHeight - intrinsicHeight) / 2;
        int deleteIconMargin = (itemHeight - intrinsicHeight) / 2;
        int deleteIconLeft = itemView.getRight() - deleteIconMargin / 3 ;

        int deleteIconRight = itemView.getRight();
        int deleteIconBottom = deleteIconTop + intrinsicHeight;

        deleteDrawable.setBounds(deleteIconLeft, deleteIconTop, deleteIconRight, deleteIconBottom);
        deleteDrawable.draw(c);

        super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);


    }

    private void clearCanvas(Canvas c, Float left, Float top, Float right, Float bottom) {
        c.drawRect(left, top, right, bottom, mClearPaint);

    }

    @Override
    public float getSwipeThreshold(@NonNull RecyclerView.ViewHolder viewHolder) {
        return 0.7f;
    }
