如何用RecyclerView实现旋转木马效果的Y轴固定

implementation 'androidx.recyclerview:recyclerview:1.2.1'

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/carouselRecyclerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

RecyclerView carouselRecyclerView = findViewById(R.id.carouselRecyclerView);
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
carouselRecyclerView.setLayoutManager(layoutManager);
carouselRecyclerView.setAdapter(new CarouselAdapter(dataList));

public class CarouselItemDecoration extends RecyclerView.ItemDecoration {
    private final int offset;
    
    public CarouselItemDecoration(int offset) {
        this.offset = offset;
    }
    
    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        super.getItemOffsets(outRect, view, parent, state);
        
        int position = parent.getChildAdapterPosition(view);
        int itemCount = parent.getAdapter().getItemCount();

        // 计算Y轴的偏移量，使得旋转木马项保持在同一水平线上
        int halfItemCount = itemCount / 2;
        int offsetPosition = position >= halfItemCount ? position - halfItemCount : position;
        outRect.top = Math.abs(offsetPosition - halfItemCount) * offset;
    }
}

int carouselOffset = getResources().getDimensionPixelOffset(R.dimen.carousel_offset);
carouselRecyclerView.addItemDecoration(new CarouselItemDecoration(carouselOffset));
