大佬教程收集整理的这篇文章主要介绍了android – MediaStyle通知没有响应RemoteControl事件.，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我们正在将正在进行的播放通知迁移到Lollipop中引入的MediaStyle通知. RemoteControlClient似乎已被弃用,MediaStyle通知不处理媒体按钮事件(例如通过耳机远程暂停/播放).

有没有人得到这项工作？ MediaSessionCallBACk中没有任何事件被调用.

以下是媒体会话的初始化方式

@H_404_6@mSession = new MediaSessionCompat(this,TAG); mSession.setCallBACk(new MediaSessionCallBACk()); mSession.setFlags(MediaSessionCompat.FLAG_HANDLES_MEDIA_BUTTONS | MediaSessionCompat.FLAG_HANDLES_TRANSPORT_CONTROLS); mSession.setPlayBACkToLocal(Au@L_654_5@manager.STREAM_MUSIC); mSession.setActive(true);

以下是设置元数据的方式

@H_404_6@mediaMetadataCompat.builder MetadataBuilder = new MediaMetadataCompat.builder(); MetadataBuilder .putLong(MediaMetadata.MetaDATA_KEY_DURATION,clip.getDuration()) .putString(MediaMetadata.MetaDATA_KEY_MEDIA_ID,clip.getClipId()) .putString(MediaMetadata.MetaDATA_KEY_titlE,clip.gettitle()) .putString(MediaMetadata.MetaDATA_KEY_ARTIST,clip.getsourc ename()) .putString(MediaMetadata.MetaDATA_KEY_ALBUM_ART_URI,clip.getImageUrl()) .putLong(MediaMetadata.MetaDATA_KEY_DURATION,clip.getDuration()); mSession.setMetadata(MetadataBuilder.build());

最后,通知代码：

@H_404_6@mediaSession mediaSession = (MediaSession) session.getMediaSession(); Notification.builder builder = new Notification.builder(C) .setDefaults(0) .setsmallIcon(R.drawable.ic_notif) .setVisibility(NotificationCompat.VISIBILITY_PUBLIC) .setContenttitle(clip.gettitle()) .setContentText(clip.getsourc ename()) .setProgress((int)duration,(int)progress,falsE) .setWhen(0) .setContenTintent(pendingIntent); if (playing) { builder.addAction(R.drawable.ic_media_pause,c.getString(R.String.media_pausE),getPendingIntentForKeyCode(app.getApplicationContext(),KeyEvent.KEYCODE_MEDIA_PAUSE)); } else { builder.addAction(R.drawable.ic_media_play,c.getString(R.String.media_play),KeyEvent.KEYCODE_MEDIA_PLAY)); } builder.addAction(R.drawable.ic_media_next,c.getString(R.String.media_next),KeyEvent.KEYCODE_MEDIA_NEXT)); builder.setStyle(new Notification.MediaStyle() .setMediaSession(mediaSession.getSessionToken()) .setShowActionsInCompactView(new int[] {1,2}) ) ); notification = builder.build(); @H_944_16@

解决方法

使用您支持的操作在MediaSession中设置播放状态：

PlayBACkState state = new PlayBACkState.builder()
        .setActions(
                PlayBACkState.ACTION_PLAY | PlayBACkState.ACTION_PLAY_PAUSE |
                PlayBACkState.ACTION_PLAY_FROM_MEDIA_ID | PlayBACkState.ACTION_PAUSE |
                PlayBACkState.ACTION_SKIP_TO_NEXT | PlayBACkState.ACTION_SKIP_TO_PREVIoUS)
        .setState(PlayBACkState.STATE_PLAYING,position,speed,SystemClock.elapsedRealtime())
        .build();
mSession.setPlayBACkState(statE);
