我使用此代码播放全屏视频，但是在播放视频时出现问题，并且从主要活动移至全屏活动时，视频冻结了2-3秒，仅出现此问题仅适用于2.8.3之后的版本，但适用于2.8.0的版本视频很流畅

答案 0 :(得分：2)
只需尝试以下代码即可解决视频冻结问题：
@Override
public void play() {
player.setPlayWhenReady(true);
player.getPlaybackState();
}
@Override
public void pause() {
player.setPlayWhenReady(false);
player.getPlaybackState();
}
player.getPlaybackState();可以帮助您恢复到原来的状态。
