Recycler view last item get truncated

It looks like my layouting is bad.
So I have a recycler view and the top app bar inside constraint layout (for positioning). And I have a swipe refresh as container. But when I run my app, the last item of recycler view is not show fully (get cut/truncated)
Here is my xml layout
<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"

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="100dp"

android:gravity="bottom"

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);

How to fix swiperefresh when one view is visible/invisible

I have recyclerview list.
If list is empty recyclerview goes to invisible or gone and another view appears to visible
If list is not empty recyclerview goes to visible.
It works fine, but when we have empty list another view appears I can't swipe to refresh in the right place (look at the screen).
I tried https://github.com/airbnb/epoxy/issues/74 but it hadn't help me.
my xml
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.example.deepdiveandroid.base.ui.view.FullScreenErrorStateView
android:id="#+id/vErrorStateNotification"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="gone" />
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:layout_width="match_parent"
android:id="#+id/vSwipeToRefreshNotification"
android:layout_height="match_parent">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rvNotificationItems"

app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
tools:listitem="#layout/layout_list_item_notification" />
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

Try to change your xml layout to this
<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"

Weird scrolling behavior and visibility of Persistent or Standard BottomSheet in a page having RecyclerView

As one can see in image, RecyclerView items are visible through Standard/Persistent BottomSheet and collapsing/expanding of BottomSheet is also not happening in Standard/Persistent BottomSheet. RecyclerView items are scrollable but when I do any kind of activity in Standard/Persistent BottomSheet, it directly scrolling the RecyclerView item behind this Standard/Persistent BottomSheet.
Note: Background color used in BottomSheet is solid. It's not transparent.
I'm wondering how to solve this issue?
Here's the code snippet ->
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

app:layout_constraintTop_toBottomOf="#id/summary" />
</androidx.constraintlayout.widget.ConstraintLayout>

As you can see in the image your bottom sheet is behind the recycler view. To change that you have to change the order of recyclerview and coordinatelayour in your activity_main.xml
You can try by changing the order like this
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
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/layout_container_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="app.standardbottomsheet.ui.MainActivity">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recycler_list"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:id="#+id/layout_container_1"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
tools:context="app.standardbottomsheet.ui.MainActivity">
<include
android:id="#+id/included_layout_standard_bottom_sheet"
layout="#layout/layout_standard_bottom_sheet" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
Since both recycler view and CoordinatorLayout are match_parent, There order decide which is above to another.

RecyclerView items overlap the rest of my layout

I try to create a RecyclerView which has to be in the bottom of my View and I want to be able to scroll the RecyclerView so I added a NestedScrollView.
But the problem is : when the RecyclerView has too many items, I'm not able to scroll and even worse because the items go the top of the screen and overlap with the rest of my layout.
<ConstraintLayout

xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="wrap_content">
<unrelated data>...</unrealated data>
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="12dp"
app:layout_constraintTop_toBottomOf="#+id/XXX"
tools:layout_editor_absoluteX="0dp">
<LinearLayout
android:id="#+id/linear_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">

app:layout_constraintStart_toStartOf="parent" />
</LinearLayout>
</androidx.core.widget.NestedScrollView>
</ConstraintLayout>
