推荐答案

这个 Android的培训仔细张贴理出头绪。正如帖子里说，

Read this Android Training post carefully to figure things out. As the post says,

Android相机应用程序保存一个全尺寸的照片，如果你给它一个文件保存到。

The Android Camera application saves a full-size photo if you give it a file to save into.

所以，如果你是传递一个文件的乌里，你应该使用访问这个图片的乌里。

so if you did pass the Uri of a file, you should access the image using this Uri.
