如何更改ListView中每个项目的背景色？

public class MyAdapter extends BaseAdapter {
    private Context mContext;
    private List<String> mData;
    private int[] mColors; // 存储每个项目的背景色

    public MyAdapter(Context context, List<String> data, int[] colors) {
        mContext = context;
        mData = data;
        mColors = colors;
    }

    @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();
        }

        // 设置每个项目的背景色
        convertView.setBackgroundColor(mColors[position]);

        // 设置每个项目的文本内容
        holder.textView.setText(mData.get(position));

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

ListView listView = findViewById(R.id.list_view);
List<String> data = new ArrayList<>();
// 添加数据到data列表中

int[] colors = new int[] {
    Color.RED, Color.GREEN, Color.BLUE // 设置每个项目的背景色
};

MyAdapter adapter = new MyAdapter(this, data, colors);
listView.setAdapter(adapter);
