今日写程序在上传代码时遇到一个问题：
0 files committed, 5 files failed to commit: 12 warning: CRLF will be replaced by LF in app/src/main/java/com/daxuetong/app/ui/invitation/activity/Activity_Photo_Look.java. The file will have its original line endings in your working directory. warning: CRLF will be replaced by LF in app/src/main/java/com/daxuetong/app/ui/invitation/adapter/PhotoLookAdapter.java.

头大，看了半天也没有看懂，只记得 CRLF 和 LF 。。。哈哈哈，终于在努力下解决了问题；
原因是找到了，MAC 与 Windows 的冲突；解决方法如下：
点击右下角的 CRLF，会出来一个如上图的小窗口，再点击 CR -Classic Mac(\r) 就可以了。再次上传文件~成功，问题解决。
