RecyclerView Item doesn't fit when using CollapsingToolbarLayout

In RecyclerView in xml design
How do I fully display the last text?
When you see the image, you will notice that the last text (TextView)
Only a small part of it is visible and the rest of the text is hidden on the screen
Here is my list_item xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="72dp"
android:paddingTop="16dp"
android:paddingRight="16dp"
android:paddingBottom="16dp">
<TextView
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="#style/TextAppearance.AppCompat.Title" />
<TextView
android:id="#android:id/text2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="#style/TextAppearance.AppCompat.Body1" />
</LinearLayout>
Here is my activity_main xml
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

Part of Linear Layout hide under Action bar

I know this may be a stupid question, however as a newbie i cant get to work around it.
So i want to add actionBar with Back Navigation Button and part of LinearLayout is hidden. How could i solve the problem ??

<!--Add Product-->
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Add Product"
android:onClick="addProduct"/>
</LinearLayout>
Expectation
I manually set margin-top to lower Linearlayout and show the expected result.

You need to add the layout behaviour to your content
<include layout="#layout/content_main"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>

You can try this. Since you are using CoordinatorLayout you need to use layout_behaviour, layout_anchor and layout_anchorGravity to properly align the layout. Just add the following line in your include:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
So it will be like this:
<include layout="#layout/content_main"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>

TextView not positioning under ImagevVew in `CoordinatorLayout`

I am developing android news app. and in my list, I have implemented image and TextView however I cant put TextView below ImageView. I have Googled it did not found useful info.
Below my CoordinatorLayout example:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center">
<LinearLayout
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="wrap_content"/>
<ImageView
android:id="#+id/articleImage"
android:layout_width="400dp"
android:layout_height="185dp" />
<TextView
android:id="#id/articleAuthor"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/article_author"/>
</android.support.design.widget.CoordinatorLayout>

You have two issues with your XML.
There is an extra LinearLayout tag that is never closed, so this shouldn't even build. You shouldn't need this and should be able to delete it.
If you want the TextView below the ImageView you need to set constraints on the TextView so it does just that.
So at minimum, you need something like this:
<?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" // <- App namespace
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center">
<ImageView
android:id="#+id/articleImage"
android:layout_width="400dp"
android:layout_height="185dp" />
<TextView
android:id="#id/articleAuthor"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/article_author"
app:layout_constraintTop_toBottomOf="#+id/articleImage" /> // <- Constraint
</android.support.design.widget.CoordinatorLayout>
I strongly recommend reviewing the ConstraintLayout documentation:
https://developer.android.com/training/constraint-layout
https://developer.android.com/reference/android/support/constraint/ConstraintLayout
Hope that helps!

Toolbar menu not showing up

I have a requirement to show bottom navigation view, drawer menu in same layout.
Bottom navigation has three tabs each has its own content.The first bottom navigation tab contains a view pager with tablayout that has some conflict with the parent toolbar.
Problem
The child fragment toolbar hides the parent toolbar menu ☰ icon.
Here is the layout I am using.

ScreenShot : Child layout having tablayout
ScreenShot : Child layout not having tablayout
But the problem is toolbar menu icon for drawer is not showing up its hiding behind the child toolbar. So any idea what is problem in my layout.
Thanks

You are overriding the Parent Activity toolbar in your Bottom Navigation View- Fragment 1
Change your layout to remove the toolbar..
BottomNavFragment1.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="wrap_content"
android:orientation="vertical">
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
app:tabGravity="fill"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#3b5998"
android:minHeight="?attr/actionBarSize"
app:tabIndicatorColor="#c8130d"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
</LinearLayout>
EDIT
In your activity layout use layout_below attribute for your FrameLayout
ParentLayout.xml
<FrameLayout
android:id="#+id/container"
android:layout_below = "#+id/appBarLayout" //add this
android:layout_width="match_parent"
android:layout_height="match_parent" />
otherwise it will replace the whole layout including the toolbar in your parent.

Prevent FAB from going down when scrolling in RecyclerView in fragment

I'm new to android development and recently learning about fragments.
I have a recyclerview inside fragment, and I want it to be attached to the toolbar, I tried put app:layout_behavior="#string/appbar_scrolling_view_behavior"
inside the container layout but whenever the toolbar shows the FAB moves down below the navigation bar as you can see here.

Thanks.

I think you must specify your layout target,
in this way:
<android.support.design.widget.FloatingActionButton
...
android:layout_gravity="bottom|end|right"
app:layout_anchor="#id/notes"
app:layout_anchorGravity="bottom|right|end"
/>
