//其他是类似结构
//在2.2版本模拟器上运行时(连接服务器一层代码完全相同),数据完全正常显示
//在用jsonxml解析字符串前,用的另一种方式解析,结果是能获取数据,但是不稳定,在多条数据获取时往往显示不全; 换了jsonxml解析后,无法获取数据。断点捕获数据交互层异常,输出2221。

//也输出Skipped 182 frames!  The application may be doing too much work on its main thread.    但我分线程了啊,断点输出当前线程名字也不是主线程,难道非得用handler,post(runable)也不行?
//请教大神们,这到底是怎么回事儿?哪的问题啊?
