Two RecyclerView below CoordinatorLayout - java

I'm tring to insert two RecyclerView inside a RelativeLayout below my CoordinatorLayout.
This is my code.

app:layout_anchorGravity="bottom|right|end"/>
</android.support.design.widget.CoordinatorLayout>
When i execute the app the second RecyclerView, recycler_view2, not appears. Why? How can i solve it?

You can try
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/details"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/recycler_view"/>
</LinearLayout>
</ScrollView>
</android.support.v4.widget.NestedScrollView>

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"

<TextView
android:id="#android:id/text2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="#style/TextAppearance.AppCompat.Body1" />

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!
https://codelabs.developers.google.com/codelabs/constraint-layout/index.html#0
The layout maybe like this
<?xml version="1.0" encoding="utf-8"?>

Fragment going over ActionBar in ViewPager

I am using viewpager to show different fragments but in this one of fragment replaces the actionbar. Till now I have found that it is because of edittext which I am using for searching items. When I remove edittext from this it works fine.
The main activity layout is a CoordinatorLayout, containing the typical AppBarLayout and then a ViewPager and it is filling whole screen.
