Question

我有一个媒体播放器服务，带有用于播放流的自定义解码器。我尝试了在网络上找到的所有内容，用于在屏幕上注册媒体控制按钮，但它们没有显示出来。

该服务的工作原理如下：

在onCreate()我做了以下事情：

audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
Intent buttonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);
ComponentName component = new ComponentName(this, MediaControlReceiver.class);

buttonIntent.setComponent(component);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, buttonIntent, 0);
myRemoteControlClient = new RemoteControlClient(pendingIntent);

audioManager.registerRemoteControlClient(myRemoteControlClient);

int flags = RemoteControlClient.FLAG_KEY_MEDIA_PREVIOUS
        | RemoteControlClient.FLAG_KEY_MEDIA_NEXT
        | RemoteControlClient.FLAG_KEY_MEDIA_PLAY
        | RemoteControlClient.FLAG_KEY_MEDIA_PAUSE
        | RemoteControlClient.FLAG_KEY_MEDIA_PLAY_PAUSE
        | RemoteControlClient.FLAG_KEY_MEDIA_STOP;
myRemoteControlClient.setTransportControlFlags(flags);

当服务收到播放消息时，我启动歌曲，并为锁屏按钮调用以下代码：

int result = audioManager.requestAudioFocus(focusChangeListener,
        AudioManager.STREAM_MUSIC,
        AudioManager.AUDIOFOCUS_GAIN);

if (result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED) {
    Log.d("RemoteControl", "Status: PLAY"  + result);
    myRemoteControlClient.setPlaybackState(RemoteControlClient.PLAYSTATE_PLAYING);
    setRemoteControlMetadata(null, "test", "test", 1);
}

我也注册了焦点更改侦听器，但没有用。你能帮我把我的应用程序连接到widget按钮吗？

RemoteControlClient在服务中，不显示小部件
