困扰好几周了，希望有时间的帮忙看看，谢了

传输数据（title，imgurl，account）当传输title或title+account时数据正常传输，但是无法传输Imgurl项，即使imgurl+title都一样，没有任何数据显示
  请教

1.httpcon.java 2.dbUtil.java

//在mainactivity中传输正常，在ej.java中数据不显示，根据System.out.println（）提示数据在httpcon.java中中断.在httpcon中初始有数据，到最后输出时数据变为空？？测试数据中断在 inputStreamtovaluelist中，但是同样的Imgurl数据在mainactivity.java中正常显示，而换了其他数据在ej.java显示也没问题？？求教啊！！

这两个方法都不一样 你怎么比较的  

private String[] myImageURL = dbUtil_1.tpxw();//imgurl传输正常
list1=dbutil_1.ejym(ej1）;

首先 方法名不一样 参数也不同 实现也不一样   你这个结果不一样 不很正常
如果是 第二个有问题  那就测试 第二个 不要拿两个比较说事  
代码 看着真累 
第二个 有参数的 不知结果 是否 本来为空 ？？？

首先感谢你帮忙。代码是长了点，我也很无奈啊，不是后边的问题，测试数据流实在httpcon.java中中断的。可能是符号在inputstreamtovaluelist中转化的问题吧
