Arrange a BottomNavigationView, a FAB, and a FrameLayout in a CoordinatorLayout and make it work with Snackbar

I want to place a FrameLayout for hosting Fragments, a BottomNavigationView and a FAB inside a CoordinatorLayout. I would like to display a Snackbar over the BottomNavigationView and FAB to move up and down to accommodate the Snackbar. I have come up with the following layout but I am unable to get Snackbar and FAB behavior correctly.
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

</androidx.coordinatorlayout.widget.CoordinatorLayout>
If I set LayoutParams like in this post then that margin 72dp margin is also displayed throwing FAB way up in the layout. If I don't use the margin the FAB will be stacked over the BottomNavigationView. I can use addCallback to set FAB margins programattically. Then also it will jump and then align itself to the right position. Overall it is not a good experience UX wise.

You get a bad behavior because you're trying to achieve something which is not common or maybe, not implemented this way by using BottomNavigationView and FAB together. It's actually more common to use FAB & BottomAppBar at the bottom of a layout.
Then also it will jump and then align itself to the right position.
Overall it is not a good experience UX wise.
Although it's not a good experience for users from a UX view, however, here are the approaches I may suggest:
Best approach : Using another CoordinatorLayout inside LinearLayout (Supported the FAB animation):
Code:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:title="Test" />
</com.google.android.material.appbar.AppBarLayout>
<androidx.core.widget.NestedScrollView
android:id="#+id/content_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<FrameLayout
android:id="#+id/fragment_cont"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</androidx.core.widget.NestedScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:id="#+id/SnackBar"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:id="#+id/extended_fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="16dp"
android:text="Chat"
android:textColor="#color/white"
app:icon="#drawable/ic_baseline_send_24"
app:iconTint="#color/white" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:layout_insetEdge="bottom"
app:menu="#menu/escrow_menu" />
</LinearLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
And in Kotlin side:
extended_fab.setOnClickListener {
val snack: Snackbar = Snackbar.make(SnackBar, " Successfully ...!", Snackbar.LENGTH_SHORT)
snack.show()
}
2. BottomAppBar & FAB & setAnchorView() method without FAB animation
Anchored to FAB
Code:
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

<!-- your FrameLayout maybe -->
<Button

app:layout_anchor="#id/bar" />
<com.google.android.material.bottomappbar.BottomAppBar
android:id="#+id/bar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
android:backgroundTint="#color/colorPrimaryDark">

</androidx.constraintlayout.widget.ConstraintLayout>

How do I use parallax to scroll through my content?

I have some issues with parallax for android, where I currently have an image on top (with text content in the center) and a button on the top right.
Now as I scroll, I want the text and button to remain fixed on screen. As I scroll past the appbar (toolbar), the toolbar should be fixed to the top and the button should be on top right of it, fixed to it , while the rest of the content stays scrollable.
Here's my code (without parallax), any clue how i can achieve this ?

As you can see from the above layout. I want to add an image (and add the my_button on top right of that image) that is above the toolbar and scrolls off the screen as you scroll up while my button stays in its place until the toolbar gets on top ,after which the toolbar is affixed to the top as you scroll further up, unless you scroll down and the image is visible again and the button is no more fixed.
Please let me know if this is confusing,I will try to explain it better with diagrams if possible.
Any examples will be helpful! thanks!

Please refer below code, i have made something like you.

Use
app:layout_scrollFlags="exitUntilCollapsed|scroll"
in collapsing layout
app:layout_collapseMode="pin"
in Toolbar

How do I correctly implement toolbars inside fragments in viewpager?

I have a collapsing toolbar in my TimelineFragment which I recently added. And there is an already existing collapsing toolbar which previously worked fine in my ProfileFragment until when I added the similar toolbar to the TimelineFragment. Both of these fragments are contained in a view pager.
I have the ff layout for the ProfileFragment

For visuals on what my issue is
** This image is from the ProfileFragment
The extra space which I marked red has not existed before, when I still haven't added the AppBarLayout (containing the toolbar) on the TimelineFragment.
I have tried removing the whole AppBarLayout on the TimelineFragment, and it does fix the weird extra space on the ProfileFragment. Why is it that there is a relation between these fragments when they do not share anything besides being in the same ViewPager?
How do I remove the space that I marked red on the image? It might be related to the toolbar since it is same in color. The AppBarLayout uses a lighter color than the toolbar.

I have already fixed it. Apparently, the Activity that was holding all these fragments is using coordinator layout. So I removed that, and that space was gone. I believe that using a toolbar inside these fragments made the activity holding them create a toolbar on its own.

Coordinator Behavior ImageView

I'm having some trouble with my CoordinatorLayout. When I scroll up I want the imageview to disappear completely.
This is an example of view and after i scroll up

I've also attempted to implement a custom behavior after finding a few examples on, especially this GitHub app example byGitskarios since our layouts are similar but it does not fix my issue. I also read Here that it may not be getting called due to it not being a direct child. How do I keep my layout and fade/hide the imageview?

The easy method is to use app:contentScrim="#color/your_toolbar_color" on the CollapsingToolbarLayout. Technically this won't get rid of the image, it will just cover it with your toolbar's color again, but it will appear to fade out and in.

Soft keyboard pushing toolbar into top status bar

I have gone through at least ten similar SO questions and nothing seems to work.
I have a simple relative layout with a toolbar, text views, edit text, etc (see xml below).
When edit text is focused I need the soft keyboard to push my layout up but under the toolbar (i.e. toolbar is pinned) but instead the keyboard pushes the entire layout up, toolbar included?
I have tried adjustPan, adjustResize, scrollviews, etc with no success, any help with this would be appreciated.

I use this code on the onCreateView of my fragment, it works fine.
getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

Use CollapsingToolbarLayout
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
app:layout_collapseMode="pin"/>
</android.support.design.widget.CollapsingToolbarLayout>
and make sure you add app:layout_collapseMode="pin" flag to your Toolbar in your layout.xml.
