public class VideoPlayerActivity extends Activity implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener, VideoControllerView.MediaPlayerControl {

    SurfaceView videoSurface;
    MediaPlayer player;
    VideoControllerView controller;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_player);

        videoSurface = (SurfaceView) findViewById(R.id.videoSurface);
        SurfaceHolder videoHolder = videoSurface.getHolder();
        videoHolder.addCallback(this);

        player = new MediaPlayer();
        controller = new VideoControllerView(this);

        try {
            player.setAudioStreamType(AudioManager.STREAM_MUSIC);
            player.setDataSource(this, Uri.parse("http:/myipadree/sites/default/files/759226_639541239394676_1125470178_n.mp4"));
            player.setOnPreparedListener(this);
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (SecurityException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        controller.show();
        return false;
    }

    // Implement SurfaceHolder.Callback
    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        player.setDisplay(holder);
        player.prepareAsync();
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {

    }
    // End SurfaceHolder.Callback

    // Implement MediaPlayer.OnPreparedListener
    @Override
    public void onPrepared(MediaPlayer mp) {
        controller.setMediaPlayer(this);
        controller.setAnchorView((FrameLayout) findViewById(R.id.videoSurfaceContainer));
        player.start();
    }
    // End MediaPlayer.OnPreparedListener

    // Implement VideoMediaController.MediaPlayerControl
    @Override
    public boolean canPause() {
        return true;
    }

    @Override
    public boolean canSeekBackward() {
        return true;
    }

    @Override
    public boolean canSeekForward() {
        return true;
    }

    @Override
    public int getBufferPercentage() {
        return 0;
    }

    @Override
    public int getCurrentPosition() {
        return player.getCurrentPosition();
    }

    @Override
    public int getDuration() {
        return player.getDuration();
    }

    @Override
    public boolean isPlaying() {
        return player.isPlaying();
    }

    @Override
    public void pause() {
        player.pause();
    }

    @Override
    public void seekTo(int i) {
        player.seekTo(i);
    }

    @Override
    public void start() {
        player.start();
    }

    @Override
    public boolean isFullScreen() {
        return false;
    }

    @Override
    public void toggleFullScreen() {

    }
    // End VideoMediaController.MediaPlayer

it is working perfect but it opening full screen if i modify layout file width and height then how to implement full screen and button full screen button

This is demo custom media control, but full screen and small screen no code. http://www.brightec.co.uk/blog/custom-android-media-controller I'm create method setFullScreen. Code below working for me.

private boolean mFullScreen = true;

@Override
public boolean isFullScreen() {   
    if(mFullScreen){    
        Log.v("FullScreen", "--set icon full screen--");
        return false;
    }else{
        Log.v("FullScreen", "--set icon small full screen--");
        return true;
    }   
}
@Override
public void toggleFullScreen() {
    Log.v("FullScreen", "-----------------click toggleFullScreen-----------");
    setFullScreen(isFullScreen());

}
// End VideoMediaController.MediaPlayerControl

public void setFullScreen(boolean fullScreen){
    fullScreen = false;

    if (mFullScreen)

    {
        Log.v("FullScreen", "-----------Set full screen SCREEN_ORIENTATION_LANDSCAPE------------"); 
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
        DisplayMetrics displaymetrics = new DisplayMetrics();
          getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
          int height = displaymetrics.heightPixels;
          int width = displaymetrics.widthPixels;
          android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();
          params.width = width;
          params.height=height;
          params.setMargins(0, 0, 0, 0);
          //set icon is full screen
         mFullScreen = fullScreen;
    }
    else{
        Log.v("FullScreen", "-----------Set small screen SCREEN_ORIENTATION_PORTRAIT------------");             
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);      
        DisplayMetrics displaymetrics = new DisplayMetrics();
          getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
          final FrameLayout mFrame = (FrameLayout) findViewById(R.id.videoSurfaceContainer);
         // int height = displaymetrics.heightPixels;
          int height = mFrame.getHeight();//get height Frame Container video
          int width = displaymetrics.widthPixels;
          android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();
          params.width = width;
          params.height= height;
          params.setMargins(0, 0, 0, 0);
          //set icon is small screen
          mFullScreen = !fullScreen;
    }
}

or use onConfigurationChanged for Rotation screen.

*@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);

  // Checks the orientation of the screen
  if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
    Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
   // setContentView(R.layout.view_lang);
      DisplayMetrics displaymetrics = new DisplayMetrics();
      getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
      int height = displaymetrics.heightPixels;
      int width = displaymetrics.widthPixels;
      android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();
      params.width = width;
      params.height=height;// -80 for android controls
      params.setMargins(0, 0, 0, 0);
  } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
    Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
    //setContentView(R.layout.view);    
    DisplayMetrics displaymetrics = new DisplayMetrics();
      getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
      int height = displaymetrics.heightPixels;
      int width = displaymetrics.widthPixels;
      android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();
      params.width = width;
      params.height=height / 3;
      params.setMargins(0, 0, 0, 0);
  }
}

add code here in AndroidManifest.xml

 android:configChanges="orientation|keyboard|keyboardHidden|screenSize" 

Sorry English !
