Is it possible to detect scroll in a view and scroll a bottomsheet accordingly?

My activity is something like
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#E7E7E7"
app:layout_constraintBottom_toTopOf="#+id/dummy"
app:layout_constraintTop_toTopOf="parent">
<include
android:id="#+id/bottomSheet"
layout="#layout/bottom_sheet_persistent" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<View
android:id="#+id/dummy"
android:background="#F44336"
android:layout_width="match_parent"
android:layout_height="80dp"
app:layout_constraintBottom_toBottomOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
And the bottom sheet is as bottom_sheet_persistent.xml
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/bottomSheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:behavior_hideable="false"
app:behavior_peekHeight="80dp"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
<View
android:layout_width="match_parent"
android:layout_height="400dp"
android:background="#2196F3"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
The screenshot is
As you can understand from the xml that, the red part is just a static view and blue is the bottomsheet. The bottomsheet also works as expected. What I wanted to achieve is, when the user start scrolls from the static view (Red View), I would like to scroll up the bottomsheet.
Thanks in advance.

Keyboard is pushing part of the layout with NestedScrollView and RcyclerView

I have a layout something like this
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/static_total_view"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#color/black"
android:gravity="bottom"
android:orientation="vertical"
android:visibility="visible"
app:layout_constraintBottom_toBottomOf="parent" />
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/static_total_view"
app:layout_constraintTop_toTopOf="parent">
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/slot_selector_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/spacing_8"
android:orientation="vertical"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
tools:itemCount="6" />
<EditText
android:id="#+id/input"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</androidx.core.widget.NestedScrollView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
However, the keyboard is pushing the bottom black view (second screenshot). If I remove RecyclerView then the keyboard works as expected and the black view is underneath (the first screenshot).
I tried the app:layout_behavior="#string/appbar_scrolling_view_behavior" .. its not working.
Any help or suggestion! Thanks in advance

You can solve this programmatically by setting the window soft input mode to SOFT_INPUT_ADJUST_PAN:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

Pin tablayout in Scrollview with appbarlayout

My android app want to have a page like Facebook page which pin the tablayout on top of the screen when scroll below the tablayout.
I have found a few answers on this topic.
pin TabLayout to top and below the toolbar Scrollview

However, they don't want my app situation because I want to keep my cardview and tablayout in the scrollview. My xml template is as below. Any insight or solution can share?

I believe you are using unnecessary layouts, try following code for guidance -
MainLayout File
<?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"
xmlns:tools="http://schemas.android.com/tools"
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">
<com.google.android.material.appbar.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentScrim="#color/colorPrimaryDark"
app:layout_scrollFlags="scroll|exitUntilCollapsed|snap">
<!-- you can put any content you want to hide after scroll in header-->
<!-- as example in putting this image view-->
<ImageView
android:layout_width="match_parent"
android:layout_height="200dp"
android:padding="20dp"
android:scaleType="fitCenter"
android:src="#drawable/default_img"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.25" />
<com.google.android.material.tabs.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_collapseMode="pin"
android:layout_gravity="bottom" />
</com.google.android.material.appbar.CollapsingToolbarLayout>
</com.google.android.material.appbar.AppBarLayout>
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<!-- put content of scroll view here -->
<include layout="scroll_content_layout" />
</androidx.core.widget.NestedScrollView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Above layout file will result in following result-
File scroll_content_layout.xml will have content you want as part of your scroll view.
ScrollContentFile
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<androidx.viewpager2.widget.ViewPager2
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<!-- some other layout as part of scroll view -->
</LinearLayout>
Edit
Content inside CollapsingToolbarLayout will collaps on scroll. Any View you want to KEEP on TOP on a scroll or any other customization you need to use layout_collapseMode flag.
CollapseMode Parallax: The content will scroll but a bit
slower than nested scroll view. You can control scroll speed with
layout_collapseParallaxMultiplier flag.
CollapseMode Pin: The content will stay in the same place while this place is still inside the collapsing toolbar.
Please check Collapse modes of CollapsingToolbarLayout
Happy coding -

Bottom Sheet Above Bottom Navigation

My goal is to place a "bottom sheet" on top of a BottomNavigationView like this:
But it stays the following way. Both views collapse:
This is the xml of my main activity:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/tierrota"

<!-- include main content -->
<include layout="#layout/bottomsheet" />
<!-- include bottom sheet -->
<include layout="#layout/bottom_navigation" />
</android.support.design.widget.CoordinatorLayout>
Code of bottom_navigation:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

</LinearLayout>
I am new with these two elements. Is there someone who knows any way to achieve what I'm looking for?
I want my "bottom sheet" to act as such and can expand. My ultimate goal is to add a RecyclerView inside the BottomSheet.

To use the BottomSheet, it should be a child of the CoordinatorLayout. Here I have used relative layout as a parent layout for bottom navigation to stay at the bottom and then CoordinatorLayout above bottom navigation.
Here's a article that will help you.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_above="#id/bottom_navigation_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/colorPrimary" />
</RelativeLayout>
<RelativeLayout
android:id="#+id/bottom_sheet_parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<LinearLayout
android:id="#+id/bottom_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<View
android:layout_width="20dp"
android:layout_height="4dp"
android:layout_gravity="center"
android:layout_marginTop="10dp"
android:background="#drawable/view_bottom_sheet_top" />
<TextView
android:id="#+id/near_by"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fontFamily="#font/normal"
android:gravity="center"
android:includeFontPadding="false"
android:padding="10dp"
android:text="Book Now"
android:textAllCaps="true"
android:textColor="?attr/colorPrimaryText"
android:textSize="12sp" />
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view_maps"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/bottom_view"
android:layoutAnimation="#anim/layout_animation">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.AppBarLayout
android:id="#+id/bottom_navigation_parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:fitsSystemWindows="true"
app:elevation="1dp">
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/colorContainerBackground"
/>
<!-- Start BottomNavigationView -->
<!-- End BottomNavigationView -->
</android.support.design.widget.AppBarLayout>
</RelativeLayout>
Don't forget to add this in your Activity/Fragment
private RelativeLayout bottomSheetParentLayout;
private BottomSheetBehavior mBottomSheetBehaviour;
mBottomSheetBehaviour = BottomSheetBehavior.from(bottomSheetParentLayout);
if (bottomNavigation != null) {
mBottomSheetBehaviour.setPeekHeight(bottomNavigation.getHeight() + 90);
}

Wrap the two elements inside a linear layout. Not sure how coordinator layout behaves but I think it will not allow you to "order" elements (similar to frame layout).

As far as I have understood your question, you want the RecyclerView to be shown in your bottom sheet. That is what makes the problem a lot easier. Let me tell you how.
You need to have a fixed height for your bottom navigation like this.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_alignParentBottom="true"
app:itemBackground="#color/colorClarito"
app:itemIconTint="#drawable/nav_item_color_state"
app:itemTextColor="#drawable/nav_item_color_state"
app:menu="#menu/bottom_navigation_main" />
</RelativeLayout>
Now in your bottom sheet, configure the RecyclerView with a clipToPadding attribute in it. Which will have some padding at the bottom of your RecyclerView. The idea is to have nothing in the covered area of the RecyclerView which is coming out with the bottom sheet.
Here's how you should declare your RecyclerView in your bottom sheet.
<android.support.v7.widget.RecyclerView
android:id="#+id/my_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:paddingBottom="80dp" />
Note that, I set the paddingBottom exactly to 80dp which is the height of the navigation view.
I hope this might help.

If you also have a CollapsingToolBar/Toolbar arrangement, this is the best solution for you:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:id="#+id/cord_main_content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:fitsSystemWindows="true"
app:layout_constraintBottom_toTopOf="#id/home_bottom_navigation_view"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/home_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/home_frag_toolbar"
style="#style/Widget.Toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:logo="#drawable/ic_infinet_logo_white"
app:navigationIcon="#drawable/ic_back_arrow" />
</com.google.android.material.appbar.AppBarLayout>
<FrameLayout
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/home_frag_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/bottom_sheet_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:clickable="true"
app:behavior_hideable="true"
app:behavior_peekHeight="#dimen/mini_player_height"
app:behavior_skipCollapsed="false"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
<FrameLayout
android:id="#+id/player_frag_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<fragment
android:id="#+id/player_mini_frag_container"
android:name="com.kokonetworks.kokonet.player.PlayMusicMiniFragment"
android:layout_width="match_parent"
android:layout_height="#dimen/mini_player_height" />
</FrameLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/home_bottom_navigation_view"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_alignParentBottom="true"
android:background="#color/colorPrimary"
app:itemBackground="#color/colorPrimary"
app:itemHorizontalTranslationEnabled="false"
app:itemIconTint="#drawable/nav_item_background"
app:itemTextColor="#drawable/nav_item_background"
app:labelVisibilityMode="auto"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:menu="#menu/home_bottom_navigation_menu" />
</androidx.constraintlayout.widget.ConstraintLayout>
It ensures that:
BottomSheet is a child of the CoordinatorLayout
BottomNavigation is still rested at the bottom
CollapsingToolbar/AppBarLayout arrangement is still in place as expected

To use the BottomSheet, it should be a child of the CoordinatorLayout, as iamnaran said.
So simply:
Put everything in RelativeLayout
Put BottomSheet in CoordinatorLayout
Set the BottomNavigation property "alignParentBottom" to true
Make new xml file in /res/value and put
<resources>
<dimen name="bottomNavigationHeight">50dp</dimen>
</resources>
Set the MarginBottom of the CoordinatorLayout (parent of BottomSheet) to
android:layout_marginBottom="#dimen/bottomNavigationHeight"
You can skip steps 4 and 5 by setting the MarginBottom of the CoordinatorLayout to:
android:layout_marginBottom="50dp"
But this may lead to confusion in near future
The whole code should look something like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

android:id="#+id/standardBottomSheet"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:elevation="9dp"
style="?attr/bottomSheetStyle"
app:layout_behavior = "com.google.android.material.bottomsheet.BottomSheetBehavior"
app:behavior_peekHeight="80dp">
</FrameLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bttm_nav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:menu="#menu/bottom_menu_nav"

</com.google.android.material.bottomnavigation.BottomNavigationView>
</RelativeLayout>

Snackbar makes RecyclerView within CoordinatorLayout slide up when it shows

I'm testing the use of Snackbar for the first time and I'm finding a behaviour which I don't understand. My Activity is composed of a Fragment, which is composed of a FrameLayout with a RecyclerView. I'm using Toolbar and Appbar.
When the Snackbar appears it moves the recyclerView up, I don't want it to behave like this, I want the Snackbar to show OVER the RecyclerView without moving it. I can however remove this from the Layout that contains the fragment:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
and then the Snackbar displays as I intend it to but of course my fragment overlaps with the Toolbar. I'm new to CoordinatorLayout so I fail to see how to get the behaviour I want. My full code is below.
My activity:

I'm using the Snack like thus, fL being the FrameLayout #+id/randomizerFragment.

Any help is welcome.
