        mDatabase = FirebaseDatabase.getInstance().getReference().child("videos");

        mDatabase.keepSynced(true);

        mBlogList = (RecyclerView) view.findViewById(R.id.blog_list);
        mBlogList.setHasFixedSize(true);
        mBlogList.setLayoutManager(new LinearLayoutManager(getContext()));


        FloatingActionButton fab = (FloatingActionButton) view.findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override

        FirebaseRecyclerAdapter<Blog, BlogViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Blog, Latest.BlogViewHolder>(

                viewHolder.setTitle(model.getTitle());

    }

        public void setImage(Context ctx, String video){
            VideoView post_video = (VideoView) mView.findViewById(R.id.post_video);
            load(video).into(post_video);
        }
    }

    public void onResume(){
        super.onResume();

        // Set title bar
        ((MainContent) getActivity())
                .setActionBarTitle("Lol Videos");

    }

}

Blog.java

public class Blog {

    private String title;
    private String desc;
    private String video;

    public Blog(){

    }

    public Blog(String title, String desc, String video) {
        this.title = title;
        this.desc = desc;
        this.video = video;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    public String getVideo() {
        return video;
    }

    public void setVideo(String video) {
        this.video = video;
    }
}

帮助我们解决这个问题。我整天都在尝试，但它不起作用。但如果我用图像替换视频，我的工作完美
