ExoPlayer将进度条定位在播放器视图的下方

// 初始化 ExoPlayer
SimpleExoPlayer player = new SimpleExoPlayer.Builder(context).build();
playerView.setPlayer(player);

// 准备媒体资源
MediaItem mediaItem = MediaItem.fromUri("https://www.example.com/video.mp4");
player.setMediaItem(mediaItem);
player.prepare();

// 创建进度条
SeekBar seekBar = findViewById(R.id.seek_bar);

// 更新进度条
player.addListener(new Player.EventListener() {
    @Override
    public void onPlaybackStateChanged(int playbackState) {
        if (playbackState == Player.STATE_READY) {
            updateSeekBar();
        }
    }
});

// 更新进度条的方法
private void updateSeekBar() {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if (player != null) {
                int currentPosition = (int) player.getCurrentPosition();
                int duration = (int) player.getDuration();
                seekBar.setMax(duration);
                seekBar.setProgress(currentPosition);
                seekBar.postDelayed(this, 1000); // 每秒更新一次
            }
        }
    });
}

// 处理进度条的拖动事件
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
        if (fromUser) {
            player.seekTo(progress);
        }
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {}

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {}
});
