如何同时滚动recylcerView和底部按钮

<LinearLayout>
    <RecyclerView
        android:id="@+id/recyclerView"
        ... />
        
    <Button
        android:id="@+id/bottomButton"
        ... />
</LinearLayout>

RecyclerView recyclerView = findViewById(R.id.recyclerView);
Button bottomButton = findViewById(R.id.bottomButton);

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
        // 在这里处理RecyclerView的滚动事件
    }
});

bottomButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 在这里处理底部按钮的点击事件
    }
});

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
        int lastVisibleItemPosition = layoutManager.findLastVisibleItemPosition();
        int itemCount = layoutManager.getItemCount();

        if (lastVisibleItemPosition == itemCount - 1) {
            // RecyclerView滚动到底部，将底部按钮滚动到可见区域
            bottomButton.setVisibility(View.VISIBLE);
        } else {
            bottomButton.setVisibility(View.GONE);
        }
    }
});

bottomButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 滚动RecyclerView到指定位置
        recyclerView.scrollToPosition(0);
    }
});
