Making the WaveView fill the remaining space after rotation is not working

[BasitTramboo]

I am trying to use the library in conjunction with the gyroscope values so that when I rotate the phone, I get the water flowing effect.

The only problem is, when the WaveView rotates, it doesn't expand it's height and width to fill the blank area that's generated in the sides. This happens even if I have given match_parent as the width.

Is there a way to get this working? Or am I getting something wrong?

I have put a stackoverflow question too, with images, here : https://stackoverflow.com/q/48369005/7947474
