Android Exoplayer SimpleExoPlayerView播放/暂停事件

有没有办法钩住SimpleExoPlayerView控件的播放/暂停单击事件？我正在尝试将chromecast连接到我的游戏活动，我需要能够响应游戏事件，以确定exoplayer是应该播放内容，还是应该将内容发送到chromecast

我认为onPlayerStateChanged可能会有帮助，但我看不到一个ExoPlayer.STATE\u播放状态

试试这个解决方案：

SimpleExoPlayerView simpleExoPlayerView = (SimpleExoPlayerView)findViewById(R.id.simpleExoView);
        simpleExoPlayerView.setControlDispatcher(new PlaybackControlView.ControlDispatcher() {
            @Override
            public boolean dispatchSetPlayWhenReady(ExoPlayer exoPlayer, boolean b) {

            // implement what you need

            return b;
        }

        @Override
        public boolean dispatchSeekTo(ExoPlayer exoPlayer, int i, long l) {
            return false;
        }
    });

在XML中

从理论上讲，这应该可以解决我的问题，但它并不漂亮。我希望在chromecast演示应用程序中实现类似于状态机的东西。除此之外，这只是部分有效。演示应用程序在启动过程中使用ExoPlayer.setPlayWhenReady，但这绕过了我们设置的SimpleExoPlayerView dispatchSetPlayWhenReady。dispatchSetPlayWhenReady被点击的唯一时间是在最初加载并点击播放按钮之后。我没有看到SimpleExoPlayerView.setPlayWhenReady会发送到底层的ExoPlayerOk，我必须通过SimpleExoPlayerView源代码进行挖掘，但我想我找到了解决方法。播放按钮似乎使用mSimpleExoPlayerView.dispatchMediaKeyEvent（新的KeyEvent（KeyEvent.ACTION\u DOWN，KeyEvent.KEYCODE\u MEDIA\u play））；它将委托给controlDispatcher.setPlayWhenReady
