如何使用Android Studio在android 10中的目录中列出所有文件? [英] How do I list all file in a directory in android 10 using Android Studio?

问题描述

我当前的代码使用:

String DirectoryPath = "/storage/emulated/0";
File f = new File(DirectoryPath);
File[] file = f.listFiles();

问题在于，该数组对于所有外部内容都为空白:

The problem is that the array comes up as blank for anything outside:

/storage/emulated/0/Android/data/com.example.myProgram

从我在网上阅读的内容来看，这不再适用于android 10+.那么，我将如何列出某个目录中的所有文件? (将文件浏览器作为应用程序的一部分)

From what I read online this no longer works with android 10+. So how would I list all files in a certain directory? (Making a file explorer as part of an App)

推荐答案

只需将这行代码添加到应用程序标记中的清单中即可.

Just add this line of code to your manifest in the application tag.

android:requestLegacyExternalStorage ="true"

android: requestLegacyExternalStorage= "true"
