So, here is what I think is going on... ImageView is basically a container for your actual image. The scaleType indicates how the image should be scaled to fit inside the ImageView. The alignParentBottom affects the container, not the image. That is why you are getting the results in your attached image.
If you set the scaleType to fitXY I would guess that you wouldn't see the blue anymore and all the images would be the same size. Note that this is not what you want to do, because that settings scales X and Y independently, which will cause your images to get stretched and look funny. You could try fitEnd, but I don't know if that will get you exactly what you want: http://developer.android.com/reference/android/graphics/Matrix.ScaleToFit.html#END Ultimately, you might have to come up with your own scale matrix...
