Get full image from pieces and make it an animated view with different behavior for each piece android

Let's say I have an animal face in pieces. I have an exterior, right ear, left ear, nose, mouse, eyes. Each of this part is independent component, so even when all of it gathered into one, animation of nose is different from ears and doesn't happen at the same time. So my question is how can I gather items together, so in future it will be a unit, but with separated behavior? Also I don't know how to place it, that ear is animating along the face, not overlaying and not with a hole between them. Any ideas? Thanks.
