红色的部分是出现的错误，为运行时异常，但就是不知道问题出现在哪里，并且从上一个Activity获取到的数据和从服务器获得的
数据都没有错，不知道是不是因为使用了线程的原因，求路过的高人指点一下，感激不尽，这个问题小弟己经纠结了好久了，调试的时候
问题时有时无。。。。。。。。。。

建议在代码中插入Log.v()来记录程序运行过程，看是哪个地方出错的
调试了好久，实在不知道是哪里的问题，根据报告的错误信息，可能是设置ArrayAdapter的问题，但看代码，实在看不出有什么不正确的地方，求解

我终于知道问题出在哪里，由于我在主线程中启动了一个子线程去更新主线程中的Spinner控件，所以会报错，我用Handler进行处理后，就没有运行时异常了
