Make ViewPager Fill The Remaining Space In a ConstraintLayout

The above code doesn't show the PageViewer at all below cardView2 , however when I set android:layout_height="500dp it does show PageViewer, but it doesn't fill the whole screen.

Initial Thoughts
I copy pasted your Layout into Android Studio 4.x, replaced all #string references with "something", and all #drawables with an existing one (from #android:drawable/) so my layout would render.
From what I see, it looks correct:
I noticed some inconsistencies in your Layout.
CardView Number 1 (top)
Careful with Padding on a CardView (don't know your min/max API so, not sure if this applies to you).
Your CardView has no constrain for its BOTTOM, it's left to "whatever size you compute after wrapping" (Height = wrap, Bottom_To = null).
This ^ means that for the CardView to have a height, all its innerwidgets must compute their sizes, so the top card view knows how much size + margin + padding it needs. It doesn't depend on OTHER widgets (that are not children) because its constrains are all to the parent. (rather it only needs its parent).
CardView Number 2 (bottom)
This cardView wraps all its dimensions but has the same issue as the one above, it doesn't constraint its height (except to be pinned at the bottom of the previous one, CardView 1). Again, this is fine, so as long as nobody depends on this (which is not true). This one has to wait on more widgets to know its size, because it has to wait on the CardView1 to know how much space is left, and also needs to know how much its children need. It's not too hard because both (the ImageView and the Button) have fixed sizes (20 and 30 dp respectively) + margins/padding.
The children of a MaterialCardView cannot/should not/must not use constraints because a CardView is not a ConstraintLayout, rather a glorified FrameLayout, which can only hold ONE child (or if it has more, it will put them on on top of the other). So all those constraints (for the shareButton and seenImageView) are ignored.
The solution to the above, is to have an inner ConstraintLayout as the sole child of a CardView, and inside this inner CL, put all your children and their constraints. The inner ConstraintLayout should have its width/height as either wrap_content or match_parent so they use the constraints of the parent. Since htey have fixed sizes, this is not an issue. (and if they didn't it wouldn't be an issue, but would need another measure pass).
Regardless of this, this second CardView is able to calculate its height, because its children are reporting a size of 20+30 (overlapped) + 15 margin top (image) so.. all this combined is likely 45dp~ of height (since they overlap only the biggest numbers apply here).
All the constraints are ignored for these two children.
ViewPager (bottom)
Finally we reach the VPager. This viewPager is match_parent for its width (since you have constraints to the start/end, you should just use 0dp). And it has wrap_content for its height.
layout_height=wrap_content -> this is a problem here. Because the viewPager doesn't (at the time of layout pass/measure) yet know what its contents are going to be. So you probably want this to be 0dp and let the ViewPager use all available space after the above has been calculated.
The marginTop you have here, will not work as it is, because the CardView 1 and 2 have no bottom constrain, so this one would have to create yet another layout/measure pass after it's all said and done to be able to apply a margin (that's how it works).
Ok Enough Rant - what can you do?
I'd "fix" the layout by adding the correct constraints and -if needed- use a VerticalChain and biasing for all widgets.
I'd fix the middle (Cardview 2) contents by wrapping the textview and imageView in a ConstraintLayout.
I'd remove left/right and replace with start/end (unless you target API 16 or below).
I'd set the ViewPager to 0dp on both dimensions.
The children of your CardView2 refer to copyButton and favoriteButton but these don't exist in the Layout you pasted, so I assume you have more buttons there).

Android make one element take rest of space

I have an activity that has one element that is rooted to the top, and another element that should take the rest of the space available. The first element's content will change over time and require different amounts of space, and the second element needs to change size with it. This is a simplified version of what I have already:
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="#+id/textview_A"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toTopOf="parent"
/>
<TextView
android:id="#+id/textview_B"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#+id/textview_A"
app:layout_constraintBottom_toBottomOf="parent"
/>
</android.support.constraint.ConstraintLayout>
The way it is currently, the top element is correct, but the second element isn't. It will adjust its position to be halfway the bottom of the top element and the bottom of the parent element, but its height is the same as its content, not all available space. How can I achieve this?

Set layout weight = 1
android: layout="1"

Alternatively, try linearlayout like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:text="text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher" />
<Button
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="D" />
</LinearLayout>
notice this special snippet:
android:layout_width="0dp"
android:layout_weight="1"

Please search before posting a question like this.
Some of the previous answers on this
Set width to match constraints in ConstraintLayout
Restrict width in ConstraintLayout by another view
Change android:layout_height of #id/testview_B to 0dp. Something like
<TextView
android:id="#+id/textview_B"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toBottomOf="#id/textview_A"
app:layout_constraintBottom_toBottomOf="parent"
/>

Centering textview with right aligned button

I have an arbitrary length textview+icon (icon+text) that needs centering on the screen. On the same row, there is a button aligned to the right side of the screen. (X)
| icon+text | X |
Using a LinearLayout I can center it with the view, but the button on the right shifts it left.
With a relative layout, I can achieve what I want but if the text is too long the button overlaps the text.
What's the right way to do this? I haven't used constraintLayout before, would that solve it?

I suggest you to use a constraint layout,
Example:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".YourActivity">
<TextView
android:id="#+id/my_text_view"
android:text="My Long Text That must not overlap the button"
android:layout_width="0dp"
android:gravity="center"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginEnd="8dp"
app:layout_constraintHorizontal_chainStyle="spread_inside"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toStartOf="#+id/my_btn"
app:layout_constraintTop_toTopOf="#+id/my_btn"
app:layout_constraintBottom_toBottomOf="#+id/my_btn"/>
<Button
android:id="#+id/my_btn"
android:layout_marginTop="16dp"
android:text="My Nice Button "
android:layout_marginEnd="8dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toEndOf="#id/my_text_view"
app:layout_constraintEnd_toEndOf="parent"/>
</android.support.constraint.ConstraintLayout>
Example Output:

You can set it like this,
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.2"
android:drawableLeft="#mipmap/ic_launcher"
android:text="Click" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.8"
android:gravity="center"
android:text="TextView" />
</LinearLayout>

just use a Relative Layout.
Center your Textview
and put toRightOf=txtViewsName on the button.
//UPDATED Forcing Widths in DP to ensure text is always centered and never overlaps button.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#mipmap/ic_launcher"
android:maxWidth="230dp"
android:layout_centerHorizontal="true"
android:ellipsize="end"
android:text="My text to show test abcdefghyijkldkf here" />
<Button
android:layout_width="80dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Button" />
</RelativeLayout>
You will need to adjust the button width and textview maxwidth to match your design, and confirm on preview all resolutions, but dp should cover you pretty well in this case.
NOTE*
This simply answers your issue, but does not do any funny behavior, i.e. if text grows too much ignore center command and start moving to the left, this does not do that. If that is your desire, please update your question.
//Centering Text in left view and using weight to ensure text area takes proper percentage of the space (based on your comments, not the layout you are looking for, but I'll leave it in case it helps someone else).
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="10">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="7"
android:drawableLeft="#mipmap/ic_launcher"
android:gravity="center"
android:text="My text to show here" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:text="Button" />
</LinearLayout>

for best practice i think ConstraintLayout is the best solution for designing and yes of course it helps you for what are you looking for.
for more info check this Build a Responsive UI with ConstraintLayout and this
ConstraintLayout.

Since your ImageButton on right has a fixed width (let's say 40dp for the purpose of this example) you can achieve the desired result by adding a margin of the same width at the end of your TextView to ensure that they're not overlapping. To keep the TextView centered on the screen you have to add the same margin at the start as well:
<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="wrap_content">
<TextView
android:id="#+id/textview"
android:text="TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="40dp"
android:layout_marginEnd="40dp"
app:layout_constrainedWidth="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageButton
android:id="#+id/button"
android:layout_width="40dp"
android:layout_height="40dp"
app:layout_constrainedWidth="true"
app:layout_constraintHorizontal_bias="1.0"
app:layout_constraintVertical_bias="0.0"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#id/textview"
app:layout_constraintTop_toTopOf="parent"/>
</android.support.constraint.ConstraintLayout>
If you want to center the text within the TextView use android:gravity="center":
If the ImageButton's width was wrap_content then this approach wouldn't work, because there is no way to constraint the end of the TextView both to the end of the parent (so it's centered on the screen) and to the start of the ImageButton (so they don't overlap if the text gets long) at the same time.

In the end I ended up using RelativeLayout per Sam's suggestion with maxWidth and margin set on the TextView.

moving items inside constraint layout cardview

This is my layout I am using for a activity.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:text="#string/user_name"
android:textAppearance="#style/TextAppearance.AppCompat.Large"
android:textSize="36sp" />
</android.support.v7.widget.CardView>
....
</android.support.constraint.ConstraintLayout>
The output looks like:
The problem is I can't move the items inside the cardview either programatically or using drag in design view of android studio.
Like, for say, I want to have
Imageview iv1_abtme(the facebook icon) below the tv_abtme
textview4 horizentally aligned to iv1_abtme
etc.
Can anyone kindly help me on what is going wrong here(why I cant simply drag items)

CardView is based on a FrameLayout and the documentation there clearly says:
Generally, FrameLayout should be used to hold a single child view, because it can be difficult to organize child views in a way that's scalable to different screen sizes without the children overlapping each other. You can, however, add multiple children to a FrameLayout and control their position within the FrameLayout by assigning gravity to each child, using the android:layout_gravity attribute.
So, to solve your problem, your CardView needs to have a single child that is a view group for your views, such as LinearLayout, RelativeLayout, or ConstraintLayout.

Positioning in ConstraintLayout causes HorizontalScrollView to cut off content

</android.support.constraint.ConstraintLayout>
I positioned the TextView wrapped by ScrollHorizontalView to be the right of the ImageView using app:layout_constraintLeft_toRightOf="#id/object_type_icon_image_view". But it caused also unexcepted behaviour. Text stored in TextView can be scrolled but it's cut off by few letters. When i delete this line app:layout_constraintLeft_toRightOf="#id/object_type_icon_image_view", text it's fully shown while scrolling. Is there any way to fix that issue?
Screens:
android:text="123456789123456789123456789123456789123456789123456789"
Before scroll when positioned to the right of ImageView
After scroll when positioned to the right of ImageView - it's cut off
Before scroll without positioning
After scroll without positioning - it's ok

Short answer:
Change the width of your HorizontalScrollView to 0dp and constrain its right-hand edge to the parent:
android:layout_width="0dp"
app:layout_constraintRight_toRightOf="parent"
Explanation:
Right now, your HorizontalScrollView is using wrap_content for its width. This makes it attempt to be as long as the text, but the parent (the ConstraintLayout) won't allow its children to have a width larger than itself. So your HorizontalScrollView winds up being the same width as the ConstraintLayout.
However, you've positioned the HorizontalScrollView such that it has been moved slightly to the right. This means that there's part of the view that is invisible; the ConstraintLayout is clipping the HorizontalScrollView.
To fix this, you need to make sure that the HorizontalScrollView is as wide as the space between the right edge of the image and the right edge of the parent. You already have a left constraint on the HorizontalScrollView, so you need to add a right constraint. Once both sides are constrained, you can use a width of 0dp to mean "match constraints"; now the HorizontalScrollView will size itself to the available space.
