标签： java android android-videoview exoplayer exoplayer2.x

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

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。
