檢索火力視頻中的Android

Question

嗨，大家好我已經succefully通過活動上傳的視頻到火力點，現在我想查看它們進入recyclerview但我不是得到它的權利

blog_row.xml

LatestVideos.java

public class Latest extends Fragment{ 

    private RecyclerView mBlogList; 
    private GridLayoutManager gridLayoutManager; 
    private DatabaseReference mDatabase; 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View view = inflater.inflate(R.layout.tab1, container, false); 

     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 
      public void onClick(View view) { 

       Intent intent = new Intent(getActivity(), UploadActivity.class); 
       startActivity(intent); 
      } 
     }); 


     return view; 
    } 

    @Override 
    public void onStart() { 
     super.onStart(); 


     FirebaseRecyclerAdapter<Blog, BlogViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Blog, Latest.BlogViewHolder>(
       Blog.class, 
       R.layout.blog_row, 
       Latest.BlogViewHolder.class, 
       mDatabase 

     ) { 
      @Override 
      protected void populateViewHolder(Latest.BlogViewHolder viewHolder, Blog model, int position) { 

       viewHolder.setTitle(model.getTitle()); 
       viewHolder.setDesc(model.getDesc()); 
       viewHolder.setImage(getActivity().getApplicationContext(),model.getImage()); 

      } 
     }; 

     mBlogList.setAdapter(firebaseRecyclerAdapter); 


    } 

    public static class BlogViewHolder extends RecyclerView.ViewHolder{ 

     View mView; 


     public BlogViewHolder(View itemView) { 
      super(itemView); 

      mView = itemView; 
     } 
     public void setTitle(String title){ 
      TextView post_title = (TextView) mView.findViewById(R.id.post_title); 
      post_title.setText(title); 
     } 

     public void setDesc(String desc){ 
      TextView post_desc = (TextView) mView.findViewById(R.id.post_desc); 
      post_desc.setText(desc); 
     } 

     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; 
    } 
} 

幫我們弄清楚這一點。我一整天都在嘗試，但它不起作用。但如果我更換圖像的視頻，我的作品完美

這是即時得到它錯了..

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

林不知道如何實現視頻URI這裏
