如何获取Android 10及以上版本共享存储文件夹的文件路径？

Uri uri = MediaStore.Downloads.getContentUri(MediaStore.VOLUME_EXTERNAL);

String[] projection = {MediaStore.Downloads._ID, MediaStore.Downloads.DISPLAY_NAME};
String selection = MediaStore.Downloads.DISPLAY_NAME + "=?";
String[] selectionArgs = new String[]{fileName};
Cursor cursor = getContentResolver().query(uri, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
    int idColumn = cursor.getColumnIndexOrThrow(MediaStore.Downloads._ID);
    long fileId = cursor.getLong(idColumn);
    Uri fileUri = ContentUris.withAppendedId(uri, fileId);
    String filePath = fileUri.toString();
    cursor.close();
}
