在Android ExoPlayer中，可以通过使用PlayerNotificationManager类来实现在屏幕锁定时继续播放的功能。下面是一个包含代码示例的解决方法：

1. 首先，确保你已经在项目的build.gradle文件中添加了ExoPlayer的依赖项：

implementation 'com.google.android.exoplayer:exoplayer-core:2.15.0'
implementation 'com.google.android.exoplayer:exoplayer-ui:2.15.0'

2. 创建一个名为PlayerService的服务类，并在AndroidManifest.xml中注册该服务：

3. 在PlayerService类中，初始化并配置ExoPlayer和PlayerNotificationManager：

public class PlayerService extends Service {

    private SimpleExoPlayer player;
    private PlayerNotificationManager notificationManager;

    @Override
    public void onCreate() {
        super.onCreate();
        
        // 初始化ExoPlayer
        player = new SimpleExoPlayer.Builder(this).build();

        // 创建一个MediaDescriptionAdapter，用于提供媒体描述信息
        PlayerNotificationManager.MediaDescriptionAdapter mediaDescriptionAdapter = new PlayerNotificationManager.MediaDescriptionAdapter() {
            @Override
            public String getCurrentContentTitle(Player player) {
                // 返回当前播放的内容标题
                return "Video Title";
            }

            @Nullable
            @Override
            public PendingIntent createCurrentContentIntent(Player player) {
                // 返回一个PendingIntent，当用户点击通知时触发
                return null;
            }

            @Nullable
            @Override
            public String getCurrentContentText(Player player) {
                // 返回当前播放的内容描述
                return "Video Description";
            }

            @Nullable
            @Override
            public Bitmap getCurrentLargeIcon(Player player, PlayerNotificationManager.BitmapCallback callback) {
                // 返回一个大图标Bitmap
                return null;
            }
        };

        // 创建一个PlayerNotificationManager，并设置相关参数
        notificationManager = PlayerNotificationManager.createWithNotificationChannel(
            this,
            "channel_id",
            R.string.channel_name,
            R.string.channel_description,
            R.drawable.ic_notification,
            mediaDescriptionAdapter
        );

        notificationManager.setPlayer(player);
        notificationManager.setUseNavigationActions(false);
        notificationManager.setUseStopAction(true);
        notificationManager.setFastForwardIncrementMs(0);
        notificationManager.setRewindIncrementMs(0);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 在这里处理播放逻辑
        return START_NOT_STICKY;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        
        // 释放ExoPlayer
        player.release();
        player = null;

        // 释放PlayerNotificationManager
        notificationManager.setPlayer(null);
        notificationManager = null;
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

4. 在需要播放视频的地方，启动PlayerService并开始播放：

Intent serviceIntent = new Intent(context, PlayerService.class);
startService(serviceIntent);

// 加载媒体资源并开始播放
Uri mediaUri = Uri.parse("https://example.com/video.mp4");
MediaSource mediaSource = new ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(mediaUri);
player.setMediaSource(mediaSource);
player.prepare();
player.setPlayWhenReady(true);

5. 最后，在PlayerService的onStartCommand方法中处理播放逻辑，以便在屏幕锁定时继续播放：

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent != null && intent.getAction() != null) {
        String action = intent.getAction();
        
        if (action.equals(AudioManager.ACTION_AUDIO_BECOMING_NOISY)) {
            // 处理耳机拔出的情况
            player.setPlayWhenReady(false);
        } else if (action.equals(Intent.ACTION_SCREEN_OFF)) {
            // 处理屏幕锁定的情况
            player.setPlayWhenReady(true);
        }
    }

    return START_NOT_STICKY;
}

现在，你已经完成了Android ExoPlayer的屏幕锁定继续播放功能的
