共享一些代码，没有做直到现在 – Abhishek

尝试做一个很好的问题。你做了什么，什么是错误日志，显示代码等。 https://stackoverflow.com/help/how-to-ask – Shudy

请先格式化代码，并添加一些关于你所做的事情的解释＆错误日志或你已经陷入困境的地方 –

声明你videoView

videoView=(VideoView)findViewById(R.id.videoView);

然后deckare的MediaController

 try { 
     // Start the MediaController 
     MediaController mediacontroller = new MediaController(
       YourAvtivityNAme.this); 
     mediacontroller.setAnchorView(videoView); 
     // Get the URL from String VideoURL 
     Uri video = Uri.parse(Video_url); 
     videoView.setMediaController(mediacontroller); 
     videoView.setVideoURI(video); 

    } catch (Exception e) { 

     Log.e("Error", e.getMessage()); 
     e.printStackTrace(); 



    }

准备的媒体播放器

videoView.requestFocus(); 
    videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
     // Close the progress bar and play the video 
     public void onPrepared(MediaPlayer mp) { 
      progressDialog.dismiss(); 
      videoView.start(); 
     } 
    });

插入您的视频网址=“”;

onCreate方法类型验证码：

try { 

      MediaController mediacontroller = new MediaController(
        VideoViewActivity.this); 
      mediacontroller.setAnchorView(videoview); 

      Uri video = Uri.parse(VideoURL); 
      videoview.setMediaController(mediacontroller); 
      videoview.setVideoURI(video); 

     } catch (Exception e) { 
      Log.e("Error", e.getMessage()); 
      e.printStackTrace(); 
     } 

     videoview.requestFocus(); 
     videoview.setOnPreparedListener(new OnPreparedListener() { 

      public void onPrepared(MediaPlayer mp) { 

       videoview.start(); 
      } 
     }); 

    }
