Top negative margin value of Android in ScrollView

I tried to give a negative marginTop value for the child inside scrollview. But this did not meet expectations. He was hiding under a layout that is above the scroll. I want to achieve the design that I mentioned in the screenshot. In particular, a logo that floated 75% in the banner and 25% below the mark. Can anyone give your ideas for this.

I used the latest Android design support library.
