Android升序自定义适配器按距离排序

public class CustomAdapter extends ArrayAdapter<Item> {
    private List<Item> items;

    public CustomAdapter(Context context, List<Item> items) {
        super(context, 0, items);
        this.items = items;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // 获取视图并进行绑定
        View view = convertView;
        if (view == null) {
            view = LayoutInflater.from(getContext()).inflate(R.layout.item_layout, parent, false);
        }

        // 获取当前位置的数据项
        Item item = items.get(position);

        // 在视图中显示数据项的内容

        return view;
    }

    public void sortByDistance() {
        // 按距离进行排序
        Collections.sort(items, new Comparator<Item>() {
            @Override
            public int compare(Item item1, Item item2) {
                // 根据距离进行比较
                return Double.compare(item1.getDistance(), item2.getDistance());
            }
        });

        // 通知适配器数据已改变
        notifyDataSetChanged();
    }
}
