我的程序放到手机上点击WAP连接，选择否，返回到住CANVERS再点选项就没反映了

摘要: 我的程序放到手机上点击WAP连接，选择否，返回到住CANVERS再点选项就没反映了

点WAP连接，弹出一个对话框，问你是否连接WAP。选择是，程序运行没什么问题，回到主界面，所有功能点击都还正常，可就是一选否，回到主界面，就选啥都没反映了。
是不是手机线程的问题啊？

试下上面代码,本人无真机测试

---

好的大哥 我试试哈
先谢了

---

不成，还那样 啊

---

你自己找一个工具调试下,看看哪句出错的

---

那你打印输出的 flag 是true还是false?

---

try{
网络连接。。
}catch(Exception e){
如果连接失败的话你要在这里面做相应的处理，就是决定你失败后的界面该显示哪个，哪些线程该结束
}

---

我没法看打印，只有在手机里头，才能调试！看不到打印输出

---

如果选择否的话，必须捕捉，捕捉后不管处理与否，程序都还可以运行，如果不捕捉就不行了。

---

有个j2meunit
可以在手机上调试的
推荐你用下

---

好的。我试试
