Android Q Beta 2在音乐通知中添加了可寻址进度条，那么我们如何在Android Q操作系统中使用编程与Spotify和SoundCloud实现呢？

您需要向媒体会话添加元数据，如持续时间和播放状态：

    MediaMetadataCompat.Builder builder = new MediaMetadataCompat.Builder();
    builder.putString(MediaMetadataCompat.METADATA_KEY_ARTIST, currentEpisode.getPodcast().getArtistName());
    builder.putString(MediaMetadataCompat.METADATA_KEY_ALBUM, currentEpisode.getPodcast().getCollectionName());
    builder.putString(MediaMetadataCompat.METADATA_KEY_TITLE, currentEpisode.getTitle());
    builder.putString(MediaMetadataCompat.METADATA_KEY_ALBUM_ART_URI, currentEpisode.getImageUrl());
    builder.putString(MediaMetadataCompat.METADATA_KEY_MEDIA_ID, currentEpisode.id);
    builder.putLong(MediaMetadataCompat.METADATA_KEY_DURATION, player.getDuration());
    mediaSessionCompat.setMetadata(builder.build());

    PlaybackStateCompat playbackStateCompat = new PlaybackStateCompat.Builder()
            .setActions(
                    PlaybackStateCompat.ACTION_PLAY | PlaybackStateCompat.ACTION_PLAY_PAUSE |
                            PlaybackStateCompat.ACTION_FAST_FORWARD | PlaybackStateCompat.ACTION_REWIND |
                            PlaybackStateCompat.ACTION_PLAY_FROM_MEDIA_ID | PlaybackStateCompat.ACTION_PAUSE |
                            PlaybackStateCompat.ACTION_SKIP_TO_NEXT | PlaybackStateCompat.ACTION_SKIP_TO_PREVIOUS | PlaybackStateCompat.ACTION_SEEK_TO)
            .setState(state, position, speedRate)
            .build();

    mediaSessionCompat.setPlaybackState(playbackStateCompat);

PlaybackStateCompat.ACTION_SEEK_TO 可以让您具备进度调整的能力。
