If you are setting a rounded png image, work around for this is to extend the floatingActionButton class then override the on onMeasure method and set the padding to 0, and scaleType To centerCrop

public class FloatingImageButton extends FloatingActionButton {


public FloatingImageButton(Context context) {
    super(context);
}

public FloatingImageButton(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    setPadding(0, 0, 0, 0);
    setScaleType(ScaleType.CENTER_CROP);


}
}
