我试图寻找用于更新meta的代码找不到任何解决方案。

您的问题不是问题,也没有详细说明。但我可以从Google示例中给您提供一个出色的Media Player,该示例名为UAMP(通用Android Media Player),它可以处理有关Android Media Player的所有内容。 Link
UAMP使用MediaMetadataCompat更新歌曲元数据,如下面的代码段所示。
fun MediaMetadataCompat.Builder.from(jsonMusic: JsonMusic): MediaMetadataCompat.Builder {
// The duration from the JSON is given in seconds, but the rest of the code works in
// milliseconds. Here's where we convert to the proper units.
val durationMs = TimeUnit.SECONDS.toMillis(jsonMusic.duration)
id = jsonMusic.id
title = jsonMusic.title
artist = jsonMusic.artist
album = jsonMusic.album
duration = durationMs
genre = jsonMusic.genre
mediaUri = jsonMusic.source
albumArtUri = jsonMusic.image
trackNumber = jsonMusic.trackNumber
trackCount = jsonMusic.totalTrackCount
flag = MediaItem.FLAG_PLAYABLE
// To make things easier for *displaying* these, set the display properties as well.
displayTitle = jsonMusic.title
displaySubtitle = jsonMusic.artist
displayDescription = jsonMusic.album
displayIconUri = jsonMusic.image
// Add downloadStatus to force the creation of an "extras" bundle in the resulting
// MediaMetadataCompat object. This is needed to send accurate metadata to the
// media session during updates.
downloadStatus = STATUS_NOT_DOWNLOADED
// Allow it to be used in the typical builder style.
return this
}
通过此组件,您可以在通知,锁定屏幕和主屏幕中更新歌曲数据。

要更新歌曲的元数据,我们可以使用ID3标签进行。我们可以使用Mp3Tag编辑器-https://github.com/aminb/id3r更新它们 ,MyID3()编辑器-https://github.com/ericfarng/jid3lib 和Jaudiotagger-https://github.com/Adonai/jaudiotagger。
Mp3Tag编辑器-仅支持Mp3歌曲类型 MyID3编辑器-可以轻松编辑歌曲,但并非所有提供的字段都已更新 Jaudiotagger-支持 MP3, Flac, OggVorbis, MP4, 阿菲 哇, Wma, DSF 音频格式 它更新数据没有任何问题
try {
val audioFile = AudioFileIO.read(file)
val tag = audioFile?.tagOrCreateAndSetDefault
tag?.setField(FieldKey.ARTIST, binding?.tiArtist?.text?.toString())
tag?.setField(FieldKey.ALBUM, binding?.tiAlbum?.text?.toString())
tag?.setField(FieldKey.GENRE, binding?.tiGenre?.text?.toString())
tag?.setField(FieldKey.TITLE, binding?.tiTrack?.text?.toString())
// Handle the image setting
try {
val pfd = contentResolver.openFileDescriptor(imageUri, "r") ?: return
val fis = FileInputStream(pfd.fileDescriptor)
val imgBytes = JavaUtils.readFully(fis)
val cover = AndroidArtwork()
cover.binaryData = imgBytes
cover.mimeType = ImageFormats.getMimeTypeForBinarySignature(byteArray)
cover.description = ""
cover.pictureType = PictureTypes.DEFAULT_ID
tag?.deleteArtworkField()
tag?.setField(cover)
fis.close()
// to do check the file write option for both internal and external card
// Handle the Storage Access FrameWork API if song is from SD card
if (audioFile?.file?.let { SafUtils.isSafNeeded(it, this) } == true) {
// Handle writing into SD card
// Check if SAF permission is provided then only we can update metadata
// If SAF Permission is not provided. EACCESS : Permission Denied error is displayed
// After the permission success then only we can update meta.
writeIntoSDCard()
} else {
// Handle writing into internal card
writeInInternalStorage()
}
} catch (e: Exception) { }
} catch (e: Exception) {
// Show error on failure while writing
} catch (e: Error) {
// Show error on failure while writing
}
编写元数据
// After update refresh the file else the changes will not be reflected
AudioFileIO.write(audioFile)
MediaScannerConnection.scanFile(context, arrayOf(file?.absolutePath ?: ""), null, null)
