Content overlapping on BottomNavigationView

I'm using BottomNavigationView on my app.
Like

The problem I'm fetching the contents of the included layout is going under the BottomNavigationView.
Can't figure out what should I do.
I want the content of content_artist__details just above the BottomNavigationView.

Can you try using layout_marginBottom = "#dimen/app_bar_height"
And since you have only RecyclerView in the nested layout you could update your code to something like this,
<android.support.v7.widget.RecyclerView
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:visibility="visible"
android:id="#+id/songListArtistRec"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="wormhole.musicx.activity.Artist_Details"
tools:showIn="#layout/activity_artist__details"
android:layout_marginBottom="#dimen/app_bar_height"/>

How to make one of child view of nestedscrollview to sticky header?

<!-- Below tablayout I want to work as a sticky header -->

<!--android:background="#color/colorPrimary" />--> </LinearLayout>
</android.support.v4.widget.NestedScrollView>
The commented tablayout should work as a sticky header(meaning it should not scroll when it reaches to top while scrolling).How to achive this effect using the coordinate layout?OR In any other way.Can we use custom behavior or something?

You can use the following library to achieve this effect.
https://github.com/emilsjolander/StickyScrollViewItems
This is basically a custom scroll view and within this scroll view you can make any child view or layout as sticky by adding the tag:
android:tag="sticky"
Hope it helps!

All you have to do is move the TabLayout to the AppBarLayout.
Since the TabLayout doesn't have scroll flags defined, it will stick to the top of the layout when you scroll.
When you do this, the app bar height needs to be changed to wrap_content and the 400dp height needs to go to the CollapsingToolbarLayout.
I just took the AppBarLayout snippet from your entire XML to demonstrate:
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbarLayout"
android:layout_width="match_parent"
android:layout_height="400dp"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|enterAlwaysCollapsed">
<ImageView
android:id="#+id/poster"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/poster_of_movie"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#color/colorPrimary" />
</android.support.design.widget.AppBarLayout>

You have to put your Toolbar inside CollapsingToolbarLayout
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

CollapsingToolbarLayout design failure

I am creating an CollapsingToolbarLayout and it should look like this:
But it has this ugly blue "thing" under it:
And here is the XML (It's in a coordinatorlayout, but it gets cut away.):

What could be the error? I also tried a vertical image. Thank you!

I have a layout like you, can you try with this layout structure , I think adding android:layout_below="#+id/profileactivity_appbar" was fixed my problem
Also you have no scroll flags in your Toolbar
Another thing I see; make sure your transition transforms image correctly:

NestedScrollView scroll lags until CollapsingToolbarLayout view does not collapse

Hi I am experincing a kind of lag when NestedScrollView is scrolled and this scroll lag is observed until view does collapse once view is collapsed scroll is working fine.
Is there any solution not this.

It seems you need to use this library. I think it will solve your problem.

Your layout should be in this structure with perfect tags....tags are main for the parallax effect.
