如何确定按钮在RecylerView布局中的位置？我不想让按钮与RecyclerView中的图像一起滚动

// 创建RecyclerView布局
RecyclerView recyclerView = findViewById(R.id.recyclerView);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);

// 创建按钮布局
RelativeLayout buttonLayout = findViewById(R.id.buttonLayout);

// 设置按钮的位置
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WRAP_CONTENT,
    RelativeLayout.LayoutParams.WRAP_CONTENT
);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_END);
buttonLayout.setLayoutParams(layoutParams);

// 设置按钮的滚动效果
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        // 根据需要调整按钮布局的位置
        int scrollY = recyclerView.computeVerticalScrollOffset();
        buttonLayout.setTranslationY(scrollY);
    }
});
