Based on this tutorial, https://github.com/saulmm/CoordinatorBehaviorExample,I am trying to create an application which have a circle image that scrolls up to the Right of Toolbar and when scrolling down goes to the middle of the expanded AppBarLayout.
How to make it move to right of Toolbar with above mentiond behaviour and animation.
AppBarTranslateScaleBehavior will help you achieve such a behavior.

I know how to use the CoordinatorLayout with CollapsingToolbarLayout to make it so that the toolbar and an imageview behaves as parallax but is there a way to make it so that an entire layout behaves as a parallax? or an imageview is the image that is pinned?
I'm trying to make it so that the toolbar in the background does not collapse completely the contents still scroll over the layout if that makes sense.
I am using collapsing toolbar. Is it somehow possible to achieve behavior, that will change multiple views in collapsing toolbar according to scrolling? For example I have three RelativeLayouts next to each other consisting of an ImageView (centered in parent) and text (below image) in collapsing toolbar. I want it for example to move image to left top, to move text to end of image and resize its height.
This wireframe shows a little what I would like to achieve:
Try use CollapsingToolbarLayout in the AppBarLayout.
Put big views to the CoollapingToolbarLayout. And Small views in the Toolbar.
You can try play with flag:
app:layout_scrollFlags="scroll|exitUntilCollapsed|snap"
If you want create rely cool animation for text in the text view.
You must implement all behavior in Java code.
I wanted to create a layout as shown in picture, with following contents as follows,
a)Toolbar
b)Collapsing toolbar
c)container with many edittext and button with nested scrollview
I am not able to create this layout with collapsing toolbar as how to place the image between 2 and 3 with both area having separate background.
Any help would be greatly appreciated.
The classic coordinator layout gives you the following [source]:
However, I don't want the top header views to scroll until they "become" a toolbar pinned at the top, with a shadow below. I want them all fixed (or pinned) but to show the shadow only the nested scroll view starts to scroll under the pinned ones. Something like the main app drawer on Marshmallow devices, where the "search bar" becomes pinned and the list of apps scroll under it.
Hope I made myself clear. Is there any easy way I could achieve that without listening for scroll events and handling this manually?
EDIT
Here is what I'm trying to achieve:
. Notice on the right image how there is now a shadow below the list of apps because the user scrolled the list.
Thank you!
This is exactly what you are looking for: HideOnScroll
Set actionBar elevation to 0 initially. Add a scroll listener to your scrolling element. When you detect it has scrolled (dy > 0) you set the actionBar elevation to 4dp(the default actionBar elevation) and back to 0dp at dy == 0.
In your scroll listener you can, at least for recyclerViews, use the canScrollVertically function to check if you're at the top or not.
I am working on a pdf reader application. When the user touches the screen, two toolbars will slide into view, overlaid on top of the pdf. There is one toolbar at the top of the screen and one at the bottom, that slide in from off-screen when touched. What is the best way to go about implementing this? I've been having trouble finding any code examples for something similar. Thanks for your help.
Put your PDF viewer inside a RelativeLayout setting match_parent for layout_width and layout_height. Then add your toolbar to that RelativeLayout setting the toolbar to layout_alignParentTop="true" will make sure the toolbar is on the top of the container. Then you can slide the toolbar in and out of the view using a TranslateAnimation between -1.0 and 0.0 for slide down, and 0.0 to -1.0 to slide out. You may have to set the visibility to GONE when the animation completes for sliding out of view.
I wrote a post some time ago about how to implement this kind of full screen with top and bottom bar. Maybe it's useful for you:
