【问题描述】：
我正在为我的 RecyclerView 使用 FirestorePagingAdapter。
当片段关闭时，我尝试在 onStop、onPasue、onDestroy 方法中停止 exoplayer，但是 它不能正常工作，它只停止 Recycler 视图中的最后一个视频，但我不明白 这里的主要问题是什么。
@Override
public void onStop() {
super.onStop();
adapter.stopListening();
if (HomeVideoHolder.simpleExoPlayer != null) {
HomeVideoHolder.simpleExoPlayer.stop();
}
}
@Override
public void onDestroy() {
super.onDestroy();
adapter.stopListening();
if (HomeVideoHolder.simpleExoPlayer != null) {
HomeVideoHolder.simpleExoPlayer.stop();
}
}
@Override
public void onPause() {
super.onPause();
adapter.stopListening();
if (HomeVideoHolder.simpleExoPlayer != null) {
HomeVideoHolder.simpleExoPlayer.stop();
}
我在 HomeVideoHolder 中将 simpleExoplayer 声明为公共静态。
public static PlayerView videoViewpath;
public static SimpleExoPlayer simpleExoPlayer;
我还尝试停止、释放、setPlayWhenReady(false) 并寻求视频结尾 停止 exoplayer。
但是每种方法都给了我相同的结果。他们只停止 recyclerView 的最后一个视频。
请给我这个问题的解决方案......
我的适配器代码...
adapter=new FirestorePagingAdapter<HomeClass, HomeVideoHolder>(options) {
@Override
protected void onBindViewHolder(@NonNull HomeVideoHolder holder, int position, @NonNull HomeClass model) {
holder.setVideoView(getActivity(),model.getAd(),model.getpId(),model.getcUid(),model.getUid(),model.getPic(),model.getVideo(),model.getcT());
}
@NonNull
@Override
public HomeVideoHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
return new HomeVideoHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.home_video_item,parent,false));
}
@Override
protected void onLoadingStateChanged(@NonNull LoadingState state) {
switch (state) {
case LOADING_INITIAL:
// The initial load has
swipeRefreshLayout.setRefreshing(true);
break;
// ...
case LOADING_MORE:
// The adapter has started to load an additional page
vLoadMore.setVisibility(View.VISIBLE);
break;
// ...
case LOADED:
// The previous load (either initial or additional) completed
swipeRefreshLayout.setRefreshing(false);
vLoadMore.setVisibility(View.INVISIBLE);
break;
// ...
case FINISHED:
vLoadMore.setVisibility(View.INVISIBLE);
break;
case ERROR:
// The previous load (either initial or additional) failed. Call
adapter.retry();
swipeRefreshLayout.setRefreshing(true);
// the retry() method in order to retry the load operation.
break;
// ...
}
}
};
我的 viewHolder 代码....
public void setVideoView(Activity activity,String ad, String pId, String cUid, String uid, String pic, String video, String cT) {
final CircleImageView chanelProfile=view.findViewById(R.id.cPicH);
final TextView chanelName=view.findViewById(R.id.cNameH);
final TextView videoCaption=view.findViewById(R.id.vDesH);
final ImageView videoThreeDot=view.findViewById(R.id.threeDotHome);
Pkey=pId;
user=FirebaseAuth.getInstance().getCurrentUser().getUid();
videoCaption.setText(cT);
setPlayer(video);
}
private void setPlayer(String video) {
if (playCode.equals("true")) {
LoadControl loadControl = new DefaultLoadControl();
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelector trackSelector = new DefaultTrackSelector(
new AdaptiveTrackSelection.Factory(bandwidthMeter)

simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(
view.getContext(), trackSelector, loadControl

"Video"

ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
MediaSource mediaSource = new ExtractorMediaSource(Uri.parse(Video),
factory, extractorsFactory, null, null
);
videoViewpath.setPlayer(simpleExoPlayer);
videoViewpath.setKeepScreenOn(true);
simpleExoPlayer.prepare(mediaSource);
simpleExoPlayer.setPlayWhenReady(false);
simpleExoPlayer.addListener(new Player.DefaultEventListener() {
@Override

case Player.STATE_READY:
addViwes();
progressBar.setVisibility(View.INVISIBLE);
break;
default:
break;
}
}
@Override
public void onRepeatModeChanged(int repeatMode) {
super.onRepeatModeChanged(repeatMode);
}
@Override
public void onShuffleModeEnabledChanged(boolean shuffleModeEnabled) {

}
@Override
public void onPositionDiscontinuity(int reason) {
super.onPositionDiscontinuity(reason);
}
@Override
public void onPlaybackParametersChanged(PlaybackParameters playbackParameters) {
super.onPlaybackParametersChanged(playbackParameters);
}
@Override
public void onSeekProcessed() {
super.onSeekProcessed();
}
});
}else {
simpleExoPlayer.stop();
simpleExoPlayer.release();
simpleExoPlayer.clearVideoSurface();
videoViewpath.setPlayer(null);
}
}
