私はexoplayerを使ってURLを通してストリーミングビデオを再生しています。チュートリアルには再生とストップビデオの2つのボタンが含まれています。このコードで必要なすべての機能を備えた通常のメディアコントローラをどのように追加してメディアプレーヤーアプリとしてメディアコントローラを表示することができるのか分かりません。androidのExoPlayerにメディアコントローラを追加する
マイコード：

ExoPlayer.Listener,HlsSampleSource.EventListener, AudioManager.OnAudioFocusChangeListener {

private static final int MAIN_BUFFER_SEGMENTS = 254;
public static final int TYPE_VIDEO = 0;
private TrackRenderer videoRenderer;
private MediaCodecAudioTrackRenderer audioRenderer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mainactivity);
surface = (SurfaceView) findViewById(R.id.surface_view); // we import surface
player = ExoPlayer.Factory.newInstance(2);
playerControl = new PlayerControl(player); // we init player
video_url = "urlhere.m3u8" +
""; //video url
am = (AudioManager) this.getApplicationContext().getSystemService(Context.AUDIO_SERVICE); // for requesting audio
mainHandler = new Handler(); //handler required for hls
userAgent = Util.getUserAgent(this, "MainActivity"); //useragent required for hls
HlsPlaylistParser parser = new HlsPlaylistParser(); // init HlsPlaylistParser
playlistFetcher = new ManifestFetcher<>(video_url, new DefaultUriDataSource(this, userAgent),
parser); // url goes here, useragent and parser
playlistFetcher.singleLoad(mainHandler.getLooper(), this); //with 'this' we'll implement ManifestFetcher.ManifestCallback<HlsPlaylist>
//listener with it will come two functions
}
//inside onSingleManifest we'll code to play hls
