我创建了一个获取视频的函数

private val projectionVideo = arrayOf(
MediaStore.Video.Media._ID, //ID
MediaStore.Video.Media.DISPLAY_NAME, //NAME
MediaStore.Video.Media.DATA, //PATH TO CONTENT
MediaStore.Video.Media.DATE_TAKEN, //DATE
MediaStore.Video.Media.DURATION,
MediaStore.Video.Media.SIZE
)

private fun queryVideos(cr: ContentResolver): Cursor? =
        cr.query(
            MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
            projectionVideo, null, null,
            MediaStore.Video.Media.DATE_TAKEN + " $SORT_ORDER"
        )

public static Uri getContentUri(String volumeName) {
                return Uri.parse(CONTENT_AUTHORITY_SLASH + volumeName +
                        "/video/media");
            }
            /**
             * The content:// style URI for the internal storage.
             */
            public static final Uri INTERNAL_CONTENT_URI =
                    getContentUri("internal");
            /**
             * The content:// style URI for the "primary" external storage
