Support android colapsing toolbar

[miladna7]

Hello dear.
thank u for Ur amazing library.
i want to add collapsing toolbar into my activity.
i use android support library for this goal.
every thing was ok, so i just add dragger as root and add to the two needed layout.
problem is, when i start activity, layout position is nut right. for example the main child posation is in the half of screen and when i touch the screen and do some scroll, layout go up and every thing is OK.
Should i use Android-ObservableScrollView?
i think it is nothing about Observing the scroll but i think it worth to mention.
