It works:
有用：
Uri selectedUri = Uri.parse(Environment.getExternalStorageDirectory() + "/myFolder/");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "resource/folder");
startActivity(intent);

我在这个GitHub repo 中找到了一个解决方案
The code :
编码 ：
If you want open & browse file:FileBrowser.class
如果你想打开和浏览文件：FileBrowser.class
Intent intent = new Intent(activity, FileBrowser::class.java)
intent.putExtra(Constants.INITIAL_DIRECTORY, File(storageDirPath).absolutePath)
intent.putExtra(Constants.ALLOWED_FILE_EXTENSIONS,"*")
startActivityForResult(intent, CODE_INTENT )
If you want to get user chosen file's URI:FileChooser.class
如果您想获取用户选择的文件的 URI：FileChooser.class
Intent intent = new Intent(activity, FileChooser::class.java)
intent.putExtra(Constants.INITIAL_DIRECTORY, File(storageDirPath).absolutePath)
startActivityForResult(intent, CODE_INTENT )

Pick root:
选根：
Intent selectFile = new Intent();
selectFile.setAction("com.sec.android.app.myfiles.PICK_DATA_MULTIPLE");
selectFile.putExtra("CONTENT_TYPE", "*/*");
selectFile.addCategory(Intent.CATEGORY_DEFAULT);
startActivity(selectFile);
