如何在颤动/省道中更改ListView项目中的背景颜色

public class MyAdapter extends BaseAdapter {
    private Context mContext;
    private List<String> mData;
    private int mSelectedPosition = -1; // 记录选中项的位置

    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 viewHolder;
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item, parent, false);
            viewHolder = new ViewHolder();
            viewHolder.textView = convertView.findViewById(R.id.text_view);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

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

        // 根据选中项的位置设置背景颜色
        if (position == mSelectedPosition) {
            convertView.setBackgroundColor(Color.BLUE);
        } else {
            convertView.setBackgroundColor(Color.WHITE);
        }

        return convertView;
    }

    public void setSelectedPosition(int position) {
        mSelectedPosition = position;
        notifyDataSetChanged();
    }

    private static class ViewHolder {
        TextView textView;
    }
}

<!-- activity_main.xml -->

public class MainActivity extends AppCompatActivity {

    private MyAdapter mAdapter;

    @Override

        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");
        // 添加更多数据...

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

        mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
