Please help me as i am not able to find any solution.

The second NestedScrollView seems to be unnecessary, you can try something like the following codes:
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

BottomNavigationView doest not shown currectly

I'm adding a BottomNavigationView to My MainActivity
at first show nothing wrong but after click on other items, BottomNavigationView strangely moving up and down. In other projects, I had never this problem and I don't know why I am getting this:
p.s: In default fragment (which is first at right in screenshot) I have a content but in other fragments, I have no content.
Here is my MainActivity layout:
<?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"
tools:context="com.activity.MainActivity">
<FrameLayout
android:id="#+id/MainActivity_FrameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/MainActivity_BottomView" />
<android.support.design.widget.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="wrap_content"

app:elevation="2dp"
app:itemTextColor="#android:color/white"
app:itemIconTint="#android:color/white"

</RelativeLayout>
and here is the screenshot of how does shown
after clicking on another item
and when select default item again

I realized it's happen when use CoordinatorLayout , AppBarLayout and CollapsingToolbarLayout in fragment . After remove that lines app work without any problem .

Change your root layout to LinearLayout like below:

I don't know what is happening but if it is anything related to image resolution and size,please tell how can i fix it from android studio itself.
If any more details will require...i will edit my question.
Thank you

You have just placed your ImageView and Toolbar in wrong place
Move your image_food ImageView and Toolbar inside CollapsingToolbarLayout
Change your layout like below code

AppbarLayout and NestedScrollView Overlaps while opening the Activity

Nested ScrollView has fragments which have RecyclerView and AppbarLayout does not scroll when dragged.
I have even added app:layout_behavior="#string/appbar_scrolling_view_behavior" in my RecyclerView as suggested in some answer but that does not work.
