Results 类很简单

手机端

　　资料 ：

　　　　1.android + java

　　　　2.http

　　　　3.json

　　结构：

①itp包下，是程序的主入口，界面很简单。

#LoginAsyncTask 里面是程序的重要部汾 http://www.2cto.com/kf/yidong/wp/" target="_blank" class="keylink">WPC9wPgo8cD4gPC9wPgo8cD7E47vhv7S1vaO6PC9wPgo8cD6hoaGhoaGhoTxpbWcgc3JjPQ=="https://www.cppentry.com/upload_files/article/76/1_p9bnq__.png" alt="\">
