在android listview中设置项目的背景色

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

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

    @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();
        }

        String item = mData.get(position);
        viewHolder.textView.setText(item);
        convertView.setBackgroundColor(mBackgroundColor);

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

ListView listView = findViewById(R.id.list_view);
List<String> data = new ArrayList<>();
data.add("Item 1");
data.add("Item 2");
data.add("Item 3");

int backgroundColor = Color.parseColor("#FF0000"); // 设置背景色为红色

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