Menu
I wanted to achieve this animation, which is the search edit box overlays the tab-layout, I must tell that I tried this code on the parent layout android:animateLayoutChanges="true" and set the tab-layout visibility to View.GONE but it just animates the tab moving up, not the search box overlays tab-layout.

I have made a quick dummy app that looks like yours, and tried to achieve what you have shown in your animation. See the effect below (you can make it more smooth and elegant) :
Its a bit tricky way of doing, the way I have done. I post my whole code here :
