Question

我正在尝试在Viewholder中播放视频，但没有播放任何内容，也没有错误消息这是我的代码：

PostAdapter

public class PostAdapter extends RecyclerView.Adapter<PostAdapter.ViewHolder>  {


    public Context mContext;
    public List<Post> mPost;


    private FirebaseUser firebaseUser;

    public PostAdapter(Context mContext, List<Post> mPost) {
        this.mContext = mContext;
        this.mPost = mPost;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.post_item, viewGroup, false);
        return new PostAdapter.ViewHolder(view);
    }


    @Override
    public void onBindViewHolder(@NonNull ViewHolder viewHolder, int i) {
        firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
        VideoView post_video;
        post_video = viewHolder.itemView.findViewById(R.id.post_video);
        Post post = mPost.get(i);
        String videourl = post.getPostvideo().toString();
        post_video.setVideoPath(videourl);
        post_video.start();

        if (post.getDescription().equals("")){
            viewHolder.description.setVisibility(View.GONE);
        } else {
            viewHolder.description.setVisibility(View.VISIBLE);
            viewHolder.description.setText(post.getDescription());
        }

        publisherInfo(viewHolder.image_profile, viewHolder.username, viewHolder.publisher, post.getPublisher());

    }

    @Override
    public int getItemCount() {
        return mPost.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder{

        public VideoView post_video;
        public ImageView image_profile, like, comment, save;
        public TextView username, likes, publisher, description, comments;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);

            image_profile = itemView.findViewById(R.id.image_profile);
            post_video = itemView.findViewById(R.id.post_video);
            like = itemView.findViewById(R.id.like);
            comment = itemView.findViewById(R.id.comment);
            save = itemView.findViewById(R.id.save);
            likes = itemView.findViewById(R.id.likes);
            publisher = itemView.findViewById(R.id.publisher);
            description = itemView.findViewById(R.id.description);
            comments = itemView.findViewById(R.id.comments);
            username = itemView.findViewById(R.id.username);


        }
    }

    private void publisherInfo(ImageView image_profile, TextView username, TextView publisher, String userid) {
        DatabaseReference reference = FirebaseDatabase.getInstance().getReference("Users").child(userid);

        reference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                User user = dataSnapshot.getValue(User.class);
                Glide.with(mContext)
                        .load(user.getImageurl())
                        .into(image_profile);
                        username.setText(user.getUsername());
                        publisher.setText(user.getUsername());

            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });
    }
}

有人知道为什么它不播放吗？正确获取了网址（已通过Toast消息进行了测试）我试图用SimpleExoPlayerView来做到这一点，但这无论如何都无法正常工作。我并没有要求完整的代码解决方案。

谢谢！
