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

SwipeRefreshLayout not working with empty List

My app contains a SwipeRefreshLayout with a listView inside of it. The list receives data from a server. So when the data is fetched and the list is populated correctly the swipe to refresh works, but when the data is not passed to the list and is empty the SwipeRefresh doesn’t work. Why can’t I swipe when the listView is empty?
That‘s my layout:

Your listview and the swipe refresh layout is within a nested scroll view which means the height of child of the nested scroll view becomes wrap content (Relative layout in your case) automatically (It also might be showing you a lint warning to replace the match parent height of your relative layout to wrap content).
therefore when there's no data in your list, the height of the whole layout group becomes 0 and the place where you need to swipe to refresh has a height of 0 and you cant swipe within a layout of height zero.
To solve this you can take a linear layout above your nested scroll view with the height of match parent and put your swipe refresh layout over it.
Let me know if you need the example code.
EDIT
Okay! so this is a workaround I found to solve the issue. You can try this and please let me know if this solves your problem.
The Idea is to wrap everything a swipe refresh layout.

ViewPager in RelativeLayout consumes full Height (Tabs)

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'?
Here is my complete XML code:

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>
