如何获得正确的路径？

Question

我正在使用 kotlin，似乎无法从 onActivityResult OPEN_DOCUMENT_TREE 获取正确的目录路径

我正在用这个

if (requestCode == REQUEST_CODE_OPEN_DOCUMENT_TREE && resultCode == Activity.RESULT_OK) {
            data?.data?.also { uri ->
val selectedDirectory = DocumentFile.fromTreeUri(activity, uri) ?: return
                // Get the primary external storage directory
                val storageDir = Environment.getExternalStorageDirectory()
                val storagePath = storageDir.absolutePath
                val path = storagePath + "/" + selectedDirectory.name

storagepath 给了我 /storage/emulated/0 这是我不想要的， selectedDirectory.name 给了我文件夹名称，但我丢失了中间的所有文件夹。例如，如果我想要 /storage/emulated/0/Download/test 我会得到 /storage/emulated/0/test。无论如何我可以有路径=完整路径吗？

Answer 1

这似乎是正确答案。

val storageDir = Environment.getExternalStorageDirectory() val storagePath = storageDir.absolutePath val path = storagePath + "/" + uri.lastPathSegment?.replace("primary:", "")
