c'est mon capture d'écran:

si je clique sur les vignettes de la vidéo va jouer une autre page: que capture d'écran:

ceci est pour mon codage:

codage 2: `

public class ViewVideo extends Activity {

    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
     WindowManager.LayoutParams.FLAG_FULLSCREEN); 

     setContentView(R.layout.main1); 
    //setContentView(new Zoom(this)); 
    Video=(VideoView)findViewById(R.id.VideoView01); 
    System.gc(); 
    Intent i = getIntent(); 
    Bundle extras = i.getExtras(); 
    filename = extras.getString("videofilename"); 
    Video.setVideoPath(filename); 

    Video.setMediaController(new MediaController(this)); 
    Video.requestFocus(); 
    Video.start(); 
    } 

    } 

quelqu'un me aider ...

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();
