从图库和Intent VideoView打开视频到新活动

Question

我想制作视频播放器应用程序，从图库启动并播放视频到“新活动”。问题是，我已经在画廊浏览了视频。视频正在“主要活动”上播放，而不是在“新活动”上播放。请帮忙。

MainActivity：

public class MainActivity extends Activity { 

Button button1; 
VideoView videoView; 
private static final int SELECT_VIDEO = 1; 


public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    button1 = (Button) findViewById(R.id.button1); 
    videoView=(VideoView)findViewById(R.id.videoView); 
    button1.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 

      Intent intent = new Intent(); 
      intent.setType("video/*"); 
      intent.setAction(Intent.ACTION_GET_CONTENT); 
      startActivityForResult(Intent.createChooser(intent, "Select Video"), SELECT_VIDEO); 

     } 
    }); 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    if (resultCode != RESULT_OK) return; 

    if (requestCode == SELECT_VIDEO) { 
     Uri mVideoURI = data.getData(); 
     videoView.setVideoURI(mVideoURI); 

     MediaController mediaController = new MediaController(this); 
     mediaController.setAnchorView(videoView); 
     videoView.setMediaController(mediaController); 

     videoView.start(); 

     } 
    } 
} 

我应该放什么编码在我的 '新activity.java'？ ，我也想把4个视频放在同一个活动中。我该怎么办？

把意图放在NewActivity中不在MainActivity中
