现在玩纸牌 [英] Now Playing Card

问题描述

我需要有关在建议"行中显示正在玩牌"的帮助.我在Android开发人员网站上阅读了有关该帖子的内容，但这并没有太大帮助.

I need help about displaying the Now Playing Card in the Recommendations row. I read the post about it in the Android developers site, but that did not help me much.

我有一项可以毫无问题地传输MP3数据的服务.我添加了以下代码，但现在没有纸牌...

I have a service that streams the MP3 data without problems. I added the following code, but there's no Now Playing Card...

@Override
public void onCreate() {
    Log.i(TAG, "onCreate called");

    mSession = new MediaSession(this, "MusicService");
    mSession.setCallback(new MediaSessionCallback());
    mSession.setFlags(MediaSession.FLAG_HANDLES_MEDIA_BUTTONS |
            MediaSession.FLAG_HANDLES_TRANSPORT_CONTROLS);

    mSession.setActive(true);
}


private class MediaSessionCallback extends MediaSession.Callback {
}

添加了元数据代码:

@Override
public void onCreate() {
    Log.i(TAG, "onCreate called");

    mSession = new MediaSession(this, "MusicService");
    mSession.setCallback(new MediaSessionCallback());
    mSession.setFlags(MediaSession.FLAG_HANDLES_MEDIA_BUTTONS |
            MediaSession.FLAG_HANDLES_TRANSPORT_CONTROLS);


    final MediaMetadata.Builder metadataBuilder = new MediaMetadata.Builder();

    String title = "Burak";

    metadataBuilder.putString(MediaMetadata.METADATA_KEY_DISPLAY_TITLE, title);
    metadataBuilder.putString(MediaMetadata.METADATA_KEY_DISPLAY_SUBTITLE,
            "Burak müzik");
    metadataBuilder.putString(MediaMetadata.METADATA_KEY_DISPLAY_ICON_URI,
            "http://commondatastorage.googleapis.com/android-tv/Sample%20videos/Zeitgeist/Zeitgeist%202010_%20Year%20in%20Review/card.jpg");

    // And at minimum the title and artist for legacy support
    metadataBuilder.putString(MediaMetadata.METADATA_KEY_TITLE, title);
    metadataBuilder.putString(MediaMetadata.METADATA_KEY_ARTIST, "BKD Mobile");

    mSession.setMetadata(metadataBuilder.build());

    mSession.setActive(true);


}

推荐答案

我说您需要通过

I would say you need to specify the metadata for the current playing MP3 file via the Metadata.Builder class:

MediaMetadata.Builder metadataBuilder = new MediaMetadata.Builder();
metadataBuilder.putString(MediaMetadata.METADATA_KEY_DISPLAY_TITLE,
        "Title");
metadataBuilder.putString(MediaMetadata.METADATA_KEY_DISPLAY_SUBTITLE,
        "Subtitle");
metadataBuilder.putString(MediaMetadata.METADATA_KEY_DISPLAY_ICON_URI,
        "Artwork");
mSession.setMetadata(metadataBuilder.build());
