如何在RecyclerView中查看不可见项目

RecyclerView recyclerView = findViewById(R.id.recyclerView);
LinearLayoutManager layoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();

// 获取第一个和最后一个可见项的位置
int firstVisibleItemPosition = layoutManager.findFirstVisibleItemPosition();
int lastVisibleItemPosition = layoutManager.findLastVisibleItemPosition();

// 获取所有不可见项的位置
for (int i = 0; i < recyclerView.getAdapter().getItemCount(); i++) {
    if (i < firstVisibleItemPosition || i > lastVisibleItemPosition) {
        // 这是一个不可见项
        Log.d("RecyclerView", "不可见项位置: " + i);
    }
}

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> dataList;

    public MyAdapter(List<String> dataList) {
        this.dataList = dataList;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.textView.setText(dataList.get(position));
    }

    @Override
    public int getItemCount() {
        return dataList.size();
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        TextView textView;

        public ViewHolder(View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.textView);
        }
    }

    // 获取数据项
    public String getItem(int position) {
        return dataList.get(position);
    }
}

MyAdapter adapter = (MyAdapter) recyclerView.getAdapter();
for (int i = 0; i < adapter.getItemCount(); i++) {
    if (i < firstVisibleItemPosition || i > lastVisibleItemPosition) {
        // 获取不可见项的数据
        String itemData = adapter.getItem(i);
        Log.d("RecyclerView", "不可见项数据: " + itemData);
    }
}

int positionToView = 10; // 你想查看的位置
recyclerView.scrollToPosition(positionToView);
