列表视图滚动更改项目视图的背景色(simpleadapter)

List<HashMap<String, Object>> dataList = new ArrayList<>();

// 准备数据源
for (int i = 0; i < 10; i++) {
    HashMap<String, Object> data = new HashMap<>();
    data.put("text", "Item " + i);
    dataList.add(data);
}

// 准备布局文件
int layoutId = R.layout.list_item;
String[] from = {"text"};
int[] to = {R.id.text_view};

// 创建SimpleAdapter
SimpleAdapter adapter = new SimpleAdapter(this, dataList, layoutId, from, to) {
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // 获取当前列表项的View
        View view = super.getView(position, convertView, parent);
        
        // 根据滚动位置或其他条件判断，动态更改背景色
        if (position % 2 == 0) {
            view.setBackgroundColor(Color.BLUE);
        } else {
            view.setBackgroundColor(Color.GREEN);
        }
        
        return view;
    }
};

ListView listView = findViewById(R.id.list_view);
listView.setAdapter(adapter);
