android 解析webservice List<Object> 填充下拉列表

依照此方式 可以实现任何的Object填充Spinner  以及调用任何免费webservice。

资源文件如下：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="black">#000000</color>
<color name="write">#00FFFFFF</color>
</resources>

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">WeatherApp</string>
    <string name="province_list_title">请选择省份</string>

    <string name="finding">搜索中</string>
    <string name="finding_province">正在搜索地区...</string>
    <string name="finding_city">正在搜索城市...</string>
</resources>

ok了 资源文件结束 不解释！ 资源中用到的图片 是一个美丽的下拉框 和一个宇宙的背景图

 

介绍一下实体类吧
