Android Exoplayer SimpleExoPlayerView Play/Pause events

Question

有没有办法挂接到SimpleExoPlayerView控件的播放/暂停点击事件？我正在尝试将 chromecast 连接到我的游戏活动，我需要能够响应播放事件，以确定 exoplayer 是应该播放内容还是应该将其发送到 chromecast。

我认为 onPlayerStateChanged 可能会对此有所帮助，但我看不到ExoPlayer.STATE_PLAYING状态。

在爪哇

videoviewholder.playerview.findViewById(R.id.exo_play).setOnClickListener(view->{
ToastUtils.showShort("play");
videoviewholder.videoItemBinding.ivExoPlayPause.setVisibility(View.INVISIBLE);
videoviewholder.videoItemBinding.playerview.getPlayer().setPlayWhenReady(true);

});
videoviewholder.playerview.findViewById(R.id.exo_pause).setOnClickListener(view->{
ToastUtils.showShort("pause");
videoviewholder.videoItemBinding.ivExoPlayPause.setVisibility(View.VISIBLE);
videoviewholder.videoItemBinding.playerview.getPlayer().setPlayWhenReady(false);

});

videoviewholder.playerview.setControllerAutoShow(true);
videoviewholder.playerview.setControllerShowTimeoutMs(0);
videoviewholder.playerview.setControllerHideOnTouch(false);
videoviewholder.playerview.setPlayer(player);

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;
}
});
