RecyclerView 曝光统计 不准确

半自动 imp 的统计触发时机是， view 从屏幕中出现。上下滚动，会造成头部和顶部的 item 被统计。
可以给您提供一个 针对 RecyclerView 的demo, 如下：

public class RecyclerViewImpActivity extends Activity {

    RecyclerView recyclerView;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_imp_recycler);
        recyclerView = findViewById(R.id.rv_imp);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        Adapter adapter = new Adapter();
        recyclerView.setAdapter(adapter);
        findViewById(R.id.btn_imp_notify).setOnClickListener(v -> {
            adapter.notifyDataSetChanged();
        });
    }

    private static class Adapter extends RecyclerView.Adapter<ViewHolder>{

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

        @Override
        public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
            holder.left.setText("position: " + position);
            JSONObject jsonObject = new JSONObject();
            try {
                jsonObject.put("position", position);
            } catch (JSONException e) {
                e.printStackTrace();
            }
            if (position == 0){
                LogUtil.d("LDK", "herererere");
            }
            GrowingIO.getInstance().markViewImpression(new ImpressionMark(holder.left, "列表项:" + position)
                    .setGlobalId(String.valueOf(position))
                    .setVariable(jsonObject));
        }

        @Override
        public int getItemCount() {
            return 100;
        }
    }

    private static class ViewHolder extends RecyclerView.ViewHolder{
        private TextView left, middle, right;

        public ViewHolder(View itemView) {
            super(itemView);
            left = itemView.findViewById(R.id.tv_left);
            middle = itemView.findViewById(R.id.tv_middle);
            right = itemView.findViewById(R.id.tv_right);
            middle.setText("中间部分");
            right.setText("两边部分");
        }
    }
}
