Only a small part of it is visible and the rest of the text is hidden on the screen

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!

</RelativeLayout>
I am working with AndroidStudio 3.0 and I am creating a TabbedActivity with Fragments using Java.
For realizing the following design:
sketch
i sourrounded the ViewPager with a RelativeLayout in order to display a static content object (TextView) below the ViewPager. For this I am using the attribute
android:layout_below="#id/container"
Unfortunately, the TextView never gets shown.
By fuzzling around i realized, that when setting the
android:layout_height="100dp"
of the ViewPager to a fixed value it will be displayed.
As I am a beginner to Android I am unsure how to handle this issue. Is it not possible to use the layout_below attribute when working with ViewPagers? Or do i have to set a fixed value for them?
Is there another solution to achieve what i want - simply showing a static content below a 'TabControl'?

Thank You very much!
Change this part of your code:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" >
</android.support.v4.view.ViewPager>
<TextView
android:id="#+id/static_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="This is the Textiew that is not shown!"
android:layout_below="#id/container"
/>
</RelativeLayout>
I would replace this with a vertical LinearLayout. This allows you to give some space to the TextView and then give the rest of the space to the ViewPager, which a RelativeLayout won't allow.
<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="match_parent"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v4.view.ViewPager>
<TextView
android:id="#+id/static_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="This is the Textiew that is not shown!"/>
</LinearLayout>
Im trying to fix the toolbar when scrolling through the content. Currently the toolbar disappears whe you scroll. I have tried this solution but I didn't manage to make it work. So far I have no solution on how to do so. Any help will be appreciated. Here is my XML Layout and a picture of the concerned layout.
