How do I make my recyclerview taking all wrap_content, when its available, but shrink down, if not?

I am sitting a long time to get my layout working. There should be an EditText on top. A RecyclerView after that. An ImageButton after that. At the bottom of the activity should be a Button. This looks fine. There is a Space between the ImageButton and Button which has height=0dp and weight=1. Rest has height=wrap_content.
When I open up the keyboard, the RecyclerView keeps being full-sized. This doesnt look fine. I want it to make space to let the Buttons fit on the screen. It should be like that
I tried to make the RecyclerView height=0dp too, but then the Space doesnt work as it should. Their height would depend on each other weight. When I remove the Space and try to get the Button to the bottom while Recyclerview has height=0dp, it would fill the entire free space, so the ImageButton would stick to the Button instead of to the end of the list.
If I would put the ImageButton as the last element of the RecyclerView, it wouldnt be always on the screen when the List is too long.
Layout-XML-only solution would be appreciated.
#edit: My layout breaks completely when I add more items. This should be fixed with the same approach.

RecyclerView does not show all items inside Fragment

The problem
In my Activity I initialize a Fragment, which contains a RecyclerView. But I've recognized that it is not displaying all items. That means instead of 14 it only shows 11 items. In addition the last visible item (number 12) is cutted off
My Implementation
The Activity contains an empty FrameLayout that acts as the Fragment container:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res./android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#e0e0e0">
<LinearLayout
android:id="#+id/layout_footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#drawable/layout_border_white"
android:paddingBottom="#dimen/footer_padding">
<include layout="#layout/footer"></include>
</LinearLayout>
<FrameLayout
android:id="#+id/fragment_start"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/layout_footer"/>
</RelativeLayout>
And here is the RecyclerView in the Fragment:
<android.support.constraint.ConstraintLayout
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:background="#e0e0e0"
android:orientation="vertical">
<LinearLayout
android:id="#+id/layout_header"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#android:color/white"
android:padding="#dimen/startpage_padding"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent">
<include layout="#layout/header"></include>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="#dimen/startpage_margin"
android:scrollbars="vertical"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#+id/layout_header"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent">
<ProgressBar
android:id="#+id/pb_loading_indicator"
android:layout_width="#dimen/startpage_progressbar"
android:layout_height="#dimen/startpage_progressbar"
android:visibility="invisible"/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent">
<TextView
android:id="#+id/tv_error_message_display"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:padding="#dimen/startpage_text_padding"
android:text="#string/error_message"
android:textSize="#dimen/startpage_text"
android:visibility="invisible"/>
</LinearLayout>
Solving Approaches
I've already tried it with match_parent in the RecyclerView and also added a paddingBottom to it. With paddingBottom="30dp" one more element is visible but that's not a good solution. Furthermore my Activity is using the AlertDialog-Theme which is setted in the Manifest. Removing it shows the same result.
Any help would be greatly appreciated.

I finally fixed it. The problem was the wrap_content in my RecyclerView inside ConstraintLayout. By using wrap_content for the height of the RecyclerView the parent cuts the bottom of it off. So you have to use 0dp for the height and a constraintBottom.
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_margin="#dimen/startpage_margin"
android:scrollbars="vertical"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="#+id/layout_header"/>

try to change your xml to following, as constraint layout wraps spaces when used in incorrect way:
<?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="match_parent"
android:orientation="vertical"
android:background="#e0e0e0">
<LinearLayout
android:id="#+id/layout_header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white">
<include layout="#layout/support_simple_spinner_dropdown_item"/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="#dimen/startpage_margin"
android:scrollbars="vertical"
android:layout_below="+id/layout_header"
/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent">
<ProgressBar
android:id="#+id/pb_loading_indicator"
android:layout_width="match_parent"
android:layout_height="10dp"
android:layout_centerInParent="true"
android:visibility="invisible"/>
<TextView
android:id="#+id/tv_error_message_display"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:text="Error"
android:textSize="20sp"
android:visibility="invisible"/>
</RelativeLayout>
</LinearLayout>

I used wrap_content for the height but the bottom of the recycleview still scrolled off bottom of the screen so that the last item was not visible. I resorted to using a finagled solution of adding a bottom padding on the recyclerview until the last item was visible

Android Textview Scrolling Issue

Firstly, I am new to android so if I have missed something basic I do apologise.
I have created a GridView to store some information. The GridView consists of a 3x6 grid. In each cell, there is an image and text directly under the image. As the GridView is so large I have implemented a scrollbar.
This is how the page should look normally and is when first loaded/selected :
Everything looks wonderful, however, when I scroll down to the bottom and then back up, the text seems to wrap up and then push the image out of place. I am not sure why this is?
This is how the page looks after I have scrolled down and they scroll back up :
For the GridView, I have an XML file with the GridView itself along with a TextView at the very top called content_rewards.xml. I have also create an XML file for each picture/text in the grid itself called relics_gridlayout.xml. I believe I am probably missing a property of the TextViews in either one of these files, however, I am not sure which one or which property. I don't think it has anything to do with the grid or adapter itself hence I will not include that code.
content_rewards.xml

This should solve your problem.
The scrolling view behavior will handle the scrolling irrespective of the size
Now add the Text view out of the Relative layout to view it always.
Or have a parent as Nested scrolling View and allow the nested scrolling enabled as false
setNestedScrollingEnabled(false)
A sample from my code that I already have used successfully to resolve such issue
Use your Grid view instead of Recycler View.
If you want the Item Text View to be always of 2 lines then set munLines="2" in the item Layout

</RelativeLayout>
</LinearLayout>

This is a problem that i faced as well , the only solution that i could come up with was hardcoding the height of the grid item.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="100dp"
android:padding="3dp">
A better option would be to use recycler view with a grid layout manager.

you can use LinearLayout and assign weights so that every item in your grid view occupy same space
Update the relics_gridlayout.xml with below code ( you may need to adjust gravity and layout weights)Try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/linearLayout_root_single_home_option"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/os_images"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher"
android:layout_weight="9" />
<TextView
android:id="#+id/os_texts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is Just Dummy Text"
android:textSize="18dp"
android:textStyle="bold"
android:layout_weight="1" />
</LinearLayout>

RecyclerView with table like layout and Sticky header -- Originally tried NestedScrollView with no success

I am building a daily schedule like for students. This schedule is in a fragment. I need a sticky header with seven day labels and then the items need to scroll underneath, all at once. In addition I need the entire view to scroll horizontally.
Currently I have a HorizontalScrollView, some nested LinearLayouts, and a NestedScrollView. There are 7 RecyclerViews that are children of the NestedScrollView, one for each day of the week. This is so that I can call setNestedScrollingEnabled(false) on each RecyclerView so they scroll together. Currently the result is that the NestedScrollView clips the RecyclerViews to 1 item and no scrolling is possible. If I remove the NestedScrollView The RecyclerViews all scroll individually which is not what I want.

</HorizontalScrollView>
The only thing of note in the fragment class is that I call setNestedScrolledEnabled(false) after populating and attaching all of the adapters.
Any insight is greatly appreciated!

The solution in this case is that I was thinking about the requirements too rigidly. I changed my layout to consists of a The header linear layout, a scrollview, and a horizontal recycler view, with each day being an item. In the adapter the item layout is simply a LinearLayout that I programmatically add the class views to(as there is a finite number of classes per day). Scrolling works in both directions. I will retitle the question so hopefully someone can find this working towards similar requirements.

Then programmatically add views to the LinearLayout. My views for each class were complex so I created a custom view based on the layout I needed for each class and then was able to just define a new instance in a for loop and add it to the LinearLayout.

How to center RecyclerView items horizontally with vertical GridLayoutManager

I have a vertical RecyclerView using a GridLayoutManager. I want each column to be centered, but the columns begin all the way on the left. In the following picture you can see what I'm talking about. I used the ugly color scheme to illustrate the columns and background. The green is the background for each item in the RecyclerView, the red is the background of the RecyclerView itself:
http://imgur.com/a/J3HtF
I'm setting it up with:
mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));
Here's the column_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="120dp"
android:layout_height="180dp"
android:orientation="vertical"
android:padding="4dp">
<ImageView
android:id="#+id/movie_column_photo"
android:layout_width="80dp"
android:layout_height="120dp"/>
<TextView
android:id="#+id/movie_column_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
Here's the recyclerview xml:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/company_details_recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</LinearLayout>

Try letting the column item fill the width of the column while centering everything inside:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="180dp"
android:orientation="vertical"
android:padding="4dp">
<ImageView
android:id="#+id/movie_column_photo"
android:layout_width="80dp"
android:layout_height="120dp"
android:layout_gravity="center_horizontal"/>
<TextView
android:id="#+id/movie_column_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"/>
</LinearLayout>

To restate #kris larson's answer;
If you are using ConstraintLayout, adding android:layout_gravity="center" or android:layout_gravity="center_horizontal" to the parent layout in item's XML would be enough (the first parent in hierarchy).
In your case, the codes would be something similar to this:
<android.support.constraint.ConstraintLayout
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_width="match_parent"
android:layout_height="180dp"
android:orientation="vertical"
android:padding="4dp"
android:layout_gravity="center">
<ImageView
android:id="#+id/movie_column_photo"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_width="80dp"
android:layout_height="120dp"/>
<TextView
android:id="#+id/movie_column_title"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.constraint.ConstraintLayout>

Simply set the width of the root layout for your column_item.xml to match_parent will center RecyclerView items horizontally.

Wrap your recyclerview inside the constraintlayout, something like this:
<androidx.constraintlayout.widget.ConstraintLayout
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" >
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/book_list"
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:spanCount="2" />
Hope it helps!!
