在锁定屏幕像谷歌媒体控制播放音乐的机器人？ [英] Media Control on Lock Screen like Google Play Music in android?

问题描述

我通过锁屏小工具文档走后，我实现它，但是这不是自动放置在主锁定窗口。我寻找解决方案，它提供媒体的控制主要锁定屏幕窗口（果冻豆及以上），如谷歌播放音乐的应用。

I had gone through Lock-screen Widget documentation, i implemented it but this is not what automatically place on main Lock Window. I searching for solution which provide Media Control over Main Lock-screen window (in Jelly Bean and above) like Google Play Music Application.

有看对谷歌播放音乐锁这显然是不锁屏插件。

Have Look on Google Play Music Lock which obviously is not Lock Screen widget.

你检查RemoteControlClient？它用于Android的音乐遥控器，即使在应用程序处于锁定状态。（你有附加同样喜欢的图像）

下面的方法，只要打电话，而你接收器播放命令采取行动，暂停，下一首，乐曲曲目previous。

Just call below method while you receiver command action for Play,Pause,Next and previous of the Song track.

  private void lockScreenControls() {

    // Use the media button APIs (if available) to register ourselves for media button
    // events

    MediaButtonHelper.registerMediaButtonEventReceiverCompat(mAudioManager, mMediaButtonReceiverComponent);
    // Use the remote control APIs (if available) to set the playback state
    if (mRemoteControlClientCompat == null) {
        Intent intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
        intent.setComponent(mMediaButtonReceiverComponent);
        mRemoteControlClientCompat = new RemoteControlClientCompat(PendingIntent.getBroadcast(this /*context*/,0 /*requestCode, ignored*/, intent /*intent*/, 0 /*flags*/));
        RemoteControlHelper.registerRemoteControlClient(mAudioManager,mRemoteControlClientCompat);
    }
    mRemoteControlClientCompat.setPlaybackState(RemoteControlClient.PLAYSTATE_PLAYING);
    mRemoteControlClientCompat.setTransportControlFlags(
            RemoteControlClient.FLAG_KEY_MEDIA_PAUSE |
            RemoteControlClient.FLAG_KEY_MEDIA_PREVIOUS |
            RemoteControlClient.FLAG_KEY_MEDIA_NEXT |
            RemoteControlClient.FLAG_KEY_MEDIA_STOP);

  //update remote controls
    mRemoteControlClientCompat.editMetadata(true)
            .putString(MediaMetadataRetriever.METADATA_KEY_ARTIST, "NombreArtista")
            .putString(MediaMetadataRetriever.METADATA_KEY_ALBUM, "Titulo Album")
            .putString(MediaMetadataRetriever.METADATA_KEY_TITLE, nombreCancion)
            //.putLong(MediaMetadataRetriever.METADATA_KEY_DURATION,playingItem.getDuration())
                    // TODO: fetch real item artwork
            .putBitmap(RemoteControlClientCompat.MetadataEditorCompat.METADATA_KEY_ARTWORK, getAlbumArt())
            .apply();
    }
}
