I'm currently facing the same problem.

I'm trying something like this, cause ViewParent has actually height set explicitly, so I use match_parent and set margins. It doesn't work all the time though, cause I simply use this view in a viewholder for RecyclerView... Also I've noticed that sometimes I see scaled up version with artifacts, sometimes full size, sometimes there are margins, and bigger margins... But it still might work for you, if you use it in a simpler scenario.

mImageViewFront.setImageDrawable(vectorDrawable);
final int paddingLR = mImageViewFront.getWidth() / 4;
final int paddingTB = mImageViewFront.getHeight() / 4;
LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
params.setMargins(paddingLR, paddingTB, paddingLR, paddingTB);
mImageViewFront.setLayoutParams(params);
