I have been working on developing application for android TV. I am using Exoplayer to play the videos. I am having issues with the video ratio. I want to play the video in full screen. I have gone through the solutions in How can I scale video in ExoPlayer-V2 - Play Video In Full Screen but it will work only if we have a xml view for the exoplayer. Since we will not have a xml view for the leanback and we use "VideoSupportFragment". How cloud I change the video ratio in leanback? I tried 

exoVideoPlayerView.setResizeMode(AspectRatioFrameLayout.RESIZE_MODE_FILL);

exoPlayer.setVideoScalingMode(C.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING);

As we will not have the ExoplayerView in leanback I was not able to use "setResizeMode" method.

How can I resize the video in Leanback Exoplayer.

In VideoSupportFragment you can change the video size by changing the dimensions of its SurfaceView. You may using the following snippet to change the dimensions:

    SurfaceView surfaceView = super.getSurfaceView();
    ViewGroup.LayoutParams params = surfaceView.getLayoutParams();
    params.height = myHeight;  // set your desired dimens
    params.width = myWidth;
    surfaceView.setLayoutParams(params);
