Thank you..

collapsing toolbar not hide all

I would like to be able to do this I know it is a CollapsingToolbarLayout but I do not know how to make some idea stop at a distance, thanks for the help
the result I want to get

A simple example of implementing a collapsing toolbar.

Replace the image inside the ImageView as per your requirement which will be visible when the toolbar is expanded.
Rest of the view can be implemented in the NestedScrollView as per your requirement.

Don't forget to give below property to your FloatingActionButton
app:layout_anchor="#id/appBar"
app:layout_anchorGravity="bottom|end"
Try something like this: almost similar to your requirements

CollapsingToolbarLayout design failure

I am creating an CollapsingToolbarLayout and it should look like this:
But it has this ugly blue "thing" under it:
And here is the XML (It's in a coordinatorlayout, but it gets cut away.):

What could be the error? I also tried a vertical image. Thank you!

I have a layout like you, can you try with this layout structure , I think adding android:layout_below="#+id/profileactivity_appbar" was fixed my problem
Also you have no scroll flags in your Toolbar
Another thing I see; make sure your transition transforms image correctly:

how to implement collapsing image view like Google IO 2015 App using Design Library

How to implement collapsing toolbar layout design like Google IO 2015 using Design Library
In Open Source Code of Google IO 2015, it is not implemented using Design Library (CoordinatorLayout, CollapsingToolbarLayout etc)
Note : In this the toolbar is at the bottom in upper section. I need the toolbar to be scrolling like this attached with the textview or any other view of upper section.

Finally i was able to implement it.

Place FAB Button Over The Map With Coordinator And NestedScroolView

I would put my FAB on the map
I tried this code but does not work.
My xml file is composed of:
Coordinatorlayout tha including AppBarLayout
that including CollapsingToolbarLayout
that including ImageView
After use a NestedScrollView With LinearLayout
that including A map (com.google.android.gms.maps.SupportMapFragment)
to follow a
FloatingActionButton.
The result is that the FAB is under the Map, and to move the NestedScrollView, i a "tapping" on the bottom.
I use API19 and Android Supporto Design Library, with Android Studio 1.5.
Sorry for the English.

You should put the FAB outside the NestedScrollView
