Android--待解决

登陆界面 , 输入框挡住了 登陆按钮

1. 列表排序

2. 数据(图片,文字)缓存(内存缓存,文件缓存) 

3. 动态监听网络变化.如果没有网络,就不能从服务器上获取东西了

6. 版本检测升级

 

 

You can use:

 

 compile 'com.nineoldandroids:library:2.4.0+'

or if you have the library copied to your project libs directory, you can use:

compile files ('libs/ nineoldandroids-2.4.0.jar')

 

 

 

发现/data的文件权限是drwxrwx--x这是linux的文件权限

第一个代表文件类型d是directory目录

后面三个是创建者的权限r读w写x执行 

再后面三个是同组者的权限 

最后三个是其他人的权限

我们从DDMS查看的时候就是其他人的权限发现只有执行 因此只需修改权限就可以了

 

编写一个ＱＱ　聊天机器人
