How do we achieve animations like the full screen example at this link:
https://material.io/components/dialogs/#full-screen-dialog
What I mean is the toolbar animations (hamburger icon to close icon, menu items), and the content expanding from right bottom to full screen. I also wonder how toolbar stays at the same place whereas content expands.
Are these custom view based animations packed together or is it somehow available to be used?

I want to place a toolbar at the bottom similar to the below, sample post compose, screenshot highlighted in green.
But the toolbar should be pushed up when the keypad comes up while entering text as below sample screenshot.
I can design the button toolbar, but no idea how to make it always visible when using keypad. Request to provide sample code for achieving this.
There are two modes for how Android can display the screen with the keyboard up- resize or pan. In pan, the application is scrolled up such that the cursor is assured to be on the page. In resize, the app is resized to fill the space left after the keyboard isplays.
You want resize. But that's not sufficient. Your layout for the screen needs to be such that the toolbar is fixed to the bottom of the screen and that the stuff above it is flexible in size. The best way to do this is to use a RelativeLayout or ConstraintLayout for the root, and to put the toolbar to align to the parent on its bottom. Make that top bar with the post button do the same with the top. Then have the stuff between them be fill_parent and have it layout below the top bar and above the bottom bar.
The end result of all that is that the top and bottom bars will be put in a fixed position, and the center part will be laid out inbetween. Note that this could result in some elements not appearing on screen until the keyboard is dismissed, because they won't fit. Putting the contents in a ScrollView can mitigate that problem, so the user could scroll to it.
I wanted to know how to use Bottom Nav View and AppBarLayout as an overlay and animate them (hide/show together on touch) just like apps like Camscanner do when viewing image? I want this behavior so that the canvas beneath it can use fullscreen.
Update
Note: This screenshot is from Gallery Go app by Google, it also hides the ActionBar and BottomNavBar.
Update 2
I used the UiAutomatorViewer to check the app's UI and found that it actually uses a LinearLayout with ImageViews for the AppBar and TextViews for the Bottom Nav View.
I have an application in which i want to hide the android status bar and make my application fullscreen. I have a set of indicator icons shown at the top row in a horizontal linear layout with a downward arrow at the middle of the view. On dragging the arrow down, i want to resize the view and show some detailed information of the indicators. This overlay should be pulled down above whatever existing content is present in my application till 50% of the height with the bottom background content losing focus and getting blurred. Something similar to the Status bar and Quick Settings overlay of SystemUI aosp application. How can i achieve this??
Initially an image will be shown having upto 1/3 of screen height and full screen width. (android.support.v7.widget.)Toolbar will be gone.
I want to animate ImageView (when page is scrolled up) to be part of Toolbar and make the toolbar visible. While scrolling down reverse action should happen.
Edit:
Similar animation can be found here. There is a minor change though, the image of giraffe will move on the toolbar and appear between left arrow and text "item 4". The animation has to be like Shared view or Hero view but on the same activity.

How can this animation be done?
Everything is simpler with the new Android Design Library
Build The Design Library Adding This Link In Your Gradle File
compile "com.android.support:design:23.1.0"
You can achieve exactly this effect by following Below Code

I hope you can achieve the functionality using the CoordinatorLayout which was launched in the new Design Library.

I am using the newest AppCompat library and replaced the SupportActionBar with a Toolbar, as suggested by the Android developer's blog. I want to display a second Toolbar at the bottom of the screen, that shows an additional Menu from some xml menu resource, but nothing else.
I have two problems with that:
Although nothing but a Menu is displayed (using Toolbar.inflateMenu()), the Menu occupies only a small space on the right side of the toolbar.
The Overflow Action Menu expands to the bottom of the toolbar and is therefore not shown. It should expand to the top.
Here is a screenshot of the bottom Toolbar:
How can I solve those issues without being forced to create custom views for my Buttons?
