title: Why my adView is half in screen area and helf out?
body: <p>I added adview to my app programatically and I want it to be added/removed (if user make a in-app purchase) bellow my recycler view. I intentionally put mu Recycler view and adview in a Linear layout (container), which I am referencing in code and adding/removing the adview. However, when I tried it, my adview is half visible in the screen and there is space on the right of it like this:

  <p>This is the code that adds the adview:</p>
