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; 
    } 
} 

帮我们弄清楚这一点。我一整天都在尝试，但它不起作用。但如果我更换图像的视频，我的作品完美

回答：

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