I have a big question, how can I do this animation (see below) on Android?

But the layout breaks, because the second Toolbar appears with a large text and stands above my Header at the time it is rolled, and even then when I I make the scrolling effect on the page, it looks like it was placed in a ScrollView and not with an effect and delay as it appears in the image above. NOTE: The scroll does not have the effect of "locking" the button as it is in a displayed image time, I have re-created the animation to show and I'm not that good, so scroll < strong> happens naturally , but with a delay in this piece that "hangs"
