无法将歌曲插入播放列表

Question

我试图将歌曲添加到现有播放列表中，但由于某种原因，该歌曲未被添加。但是没有遇到任何错误。我在日志中检查URI，它总是给出null。我传递了播放列表ID和歌曲对象。提前谢谢。

代码：

 public static void AddSongToPlaylist(SongInfoModel songInfoModel, long pID, Context context )
{


    Uri pUri = MediaStore.Audio.Playlists.Members.getContentUri("external", pID);

    ContentResolver resolver = context.getContentResolver();
    ContentValues values = new ContentValues();

    values.put(MediaStore.Audio.Playlists.Members.AUDIO_ID, songInfoModel.getSongID());
    values.put(MediaStore.Audio.Playlists.Members.TITLE, songInfoModel.getSongName());
    values.put(MediaStore.Audio.Playlists.Members.ARTIST, songInfoModel.getArtistName());
    values.put(MediaStore.Audio.Playlists.Members.DURATION, songInfoModel.getDuration());
    resolver.insert(pUri,values);
    resolver.notifyChange(Uri.parse("content://media"), null);
    Log.i("URI:",resolver.insert(pUri, values)+"");


}

传递pID和歌曲对象：

 Playlistadapter = new ListPlayListAdapter(finalDialogPlaylist, getContext(), new ListPlayListAdapter.ItemClickListener() {
                        @Override
                        public void onClickListener(PlaylistsModel playlistsModel, int position) {

                          Playlists.AddSongToPlaylist(song,playlistsModel.getPlaylistID(),getContext());

                        }
                    });

您使用的是错误的参数。

所需要的只是如下：

         Uri newuri = MediaStore.Audio.Playlists.Members.getContentUri(
            "external", playlist_id);

        ContentResolver resolver = context.getContentResolver();
        ContentValues values = new ContentValues();
        values.put(MediaStore.Audio.Playlists.Members.PLAY_ORDER, pos);
        values.put(MediaStore.Audio.Playlists.Members.AUDIO_ID, audio_id);
        values.put(MediaStore.Audio.Playlists.Members.PLAYLIST_ID,
                playlist_id);
