如何仅更改listview android中第二个单元格的背景色

public class MyAdapter extends BaseAdapter {
    private Context mContext;
    private List<String> mData;

    public MyAdapter(Context context, List<String> data) {
        mContext = context;
        mData = data;
    }

    @Override
    public int getCount() {
        return mData.size();
    }

    @Override
    public Object getItem(int position) {
        return mData.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.textView = convertView.findViewById(R.id.text_view);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        // 设置第二个单元格的背景色
        if (position == 1) {
            convertView.setBackgroundColor(Color.RED);
        } else {
            convertView.setBackgroundColor(Color.WHITE);
        }

        holder.textView.setText(mData.get(position));

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

<!-- activity_main.xml -->
<ListView
    android:id="@+id/list_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<!-- list_item.xml -->
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/text_view"

    android:padding="16dp" />

public class MainActivity extends AppCompatActivity {
    private ListView mListView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mListView = findViewById(R.id.list_view);

        List<String> data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");

        MyAdapter adapter = new MyAdapter(this, data);
        mListView.setAdapter(adapter);
    }
}
