Question

在我的应用程序中，视频播放期间的UI取决于设备方向。当设备处于纵向模式时，视频会在嵌入RecyclerView.ViewHolder RecyclerView中的Fragment对象中播放，ViewPager位于Fragment内RecyclerView内DialogFragment。当设备更改为横向模式时，RecyclerView中的视频停止付费，弹出RecyclerView.ViewHolder，并且应该开始播放@Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); int orientation = newConfig.orientation; ... } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) { orientationControlViewModel.getOrientationLiveData().setValue(true); ... } }中的视频停止播放的位置。当屏幕旋转发生时，活动通过以下代码通知LiveData：

RecyclerView.ViewHolder

DialogFragment正在观察LiveData个对象。当OrientationLiveData的值设置为true时，视频暂停，网址和当前时间通过另一个holder.orientationControlViewModel.getOrientationLiveData().observe(holder, orientationChanged -> { //currently doesn't get called Log.i("orientation3", "viewholder observing orientation live data"); if (orientationChanged && holder.equals(getNowPlayingViewHolder())){ //todo there is a lag after rotation, show loading spinner holder.binding.videoLayout.postVideoView.getPlayer().setPlayWhenReady(false); VideoInfo videoInfo = new VideoInfo(joke.getMediaURL(), holder.binding.videoLayout.postVideoView.getPlayer().getCurrentPosition()); holder.orientationControlViewModel.getVideoLiveData().setValue(videoInfo); } ... });发送到DialogFragment，如下所示：

public void onResume() {
    super.onResume();
    DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
    // Produces DataSource instances through which media data is loaded.
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(getActivity(),
            Util.getUserAgent(getActivity(), "Hilarity"), bandwidthMeter);
    SimpleCache cache = new SimpleCache(getActivity().getCacheDir(), new LeastRecentlyUsedCacheEvictor(1024^2*100));
    CacheDataSourceFactory cacheDataSourceFactory = new CacheDataSourceFactory(cache, dataSourceFactory);
    // Produces Extractor instances for parsing the media data.
    ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
    if (simpleExoPlayerView.getPlayer() != null) {
        simpleExoPlayerView.getPlayer().prepare(new ExtractorMediaSource(Uri.parse(url),
                dataSourceFactory, extractorsFactory, null, null), false, true);
        simpleExoPlayerView.getPlayer().seekTo(position);
        Log.i("orientation4", "position = " + position + " in onResume");
        simpleExoPlayerView.getPlayer().setPlayWhenReady(true);
    }
}

记录显示DialogFragment已收到要开始的位置。在onResume中，调用了seekTo（代码如下所示），但视频从头开始。

http://localhost:3000/base/a
http://localhost:3000/base/b

我的问题是，如何让base中的视频从seekTo（）方法中用作参数的位置开始？如果您对可能比当前实现的架构更好的架构有建议，请随时留下输入。
