获取使用BasicFileAttributes在Java SDK的1.8上次文件访问时间 [英] Getting last file access time using BasicFileAttributes in Java SDK 1.8

问题描述

我看到这里的大多数关于Java 1.7的previous问题并获得最后的文件访问时间。

I have seen most of the previous questions here on Java 1.7 and getting the last file access time.

下面也上导入库一个很好的片段，以及它们如何获得最后的文件访问时间：的 http://kodejava.org/how-do-i-get-file-basic-attributes/

Here's also a good snippet on import library and how they get the last file access time: http://kodejava.org/how-do-i-get-file-basic-attributes/

我这样做：

BasicFileAttributes attrs = Files.readAttributes(file, BasicFileAttributes.class);
FileTime time = attrs.lastAccessTime();

不过，在我的IntelliJ IDEA的IDE它说，BasicFileAttributes无法解析。

However, in my IntelliJ IDEA IDE it says, BasicFileAttributes could not be resolved.

所以，我进口了：

import java.nio.file.attribute.BasicFileAttributes;

但很显然，文件不能被解决。我正在运行的Java SDK 1.8，我想在我的Andr​​oid项目中使用这个，如果有差别。

But apparently, file cannot be resolved. I am running Java SDK 1.8 and I am trying to use this in my Android project if that makes a difference.

不知道为什么文件丢失在库中。

Not sure why file is missing in the library.

还有什么我是做错了什么？

What could I be doing wrong?

推荐答案

目前Android不支持所有Java 7的功能以至于忘记了有关Java 8.我提到的Java 7，因为文件在Java 7中的某些功能被引入像多抓由Android（和奇巧开始支持尝试-与资源），但文件类是没有的。请注意，谷歌不使用Oracle的Java。

Currently Android doesn't support all Java 7 features so forget about Java 8. I mentioned Java 7 because Files was introduced in Java 7. Some features like multi-catch are supported by Android(and starting with Kitkat try-with-resources ) but Files class is not. Note that Google doesn't use Oracle Java.
