誰も私を助けて...

あなたのmain.xmlファイルが何をしたか

Answer 1

 
You want to use Videoview 

<VideoView android:id="@+id/Videoview1" 
    android:layout_marginTop="100px" 
    android:layout_marginLeft="10px" 
    android:layout_width="20px" 
    android:layout_height="200px"/> 

and create object in your activity 
and play. 
videoview.start(); 
like this. 

Hope this will help you 

Answer 2

 
private VideoView mVView; 

mVView= (VideoView) findViewById(R.id.Videoview1); 

mVView.setVideoPath("sdcard/filename.mp4"); 
mVView.start();
