I'm having a ViewPager and a RecyclerView in layout file. I want to make the entire layout Scrollable. That is i want the ViewPager to be scrolled up. Hence, i added <ScrollView> as the root layout.
Issue:
The problem i'm facing is that the RecyclerView in scrolling as expected, but the ViewPager area is fixed.
The Below Image depicts the issue mentioned above:
The xml code of my layout file is as shown below:

What have i tried?
As mentioned in this answer Android ScrollView not Scrolling
, i have tried setting the ScrollView orientation to vertical and fillViewPort property to true, but the problem still persists.
I have also tried using NestedScrollView as the root, but that too didn't work.
If someone can suggest me how to go about with this, it will be really helpful to anyone facing such issue.

I have an activity LoginActivity and a fragment SignupSocialFragment.
The fragment is loaded inside of the FrameLayout inside the activity.
The problem is, that the LinearLayout (social_login_footer) in fragment which is constrained to the bottom of its parent is cut of when the fragment is displayed in the activity.
When I add padding/margin to the social_login_footerI can shift it into view but this does not work reliable.
Can anyone help with why the bottom part is cut of?
Shouldnt the ConstraintLayout match the height of its parent FrameLayout.

After wasting some hours of my precious lifetime I have finally found it.
The problem is caused by the ImageViews android:adjustViewBounds="true" attribute.
After removing it everything works as expected.
Try adding android:fitsSystemWindows="true" to fragment_login_social.xml first child view
I have an app that displays long strings of text with the press of some buttons, the problem comes when I display a lot of text and the ScrollView just stops scrolling for some reason.
Here is the xml of my app:

I have seen some people use this same method that I'm using here and it works for them just fine.
Your layout has a few things that look wrong and could explain
undefined behaviour.
change the ScrollView height and width to 0dp which means to respect the constraints set on the view
<ScrollView
android:layout_width="0dp"
android:layout_height="0dp"
...
Remove the constraints from the child of the ScrollView as ContraintLayout only applies rules to direct children.
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginEnd="14dp"
android:layout_marginStart="16dp"
android:layout_marginTop="128dp"
android:text=""

My xml is composed by one constraint layout. Inside this there are 2 buttons and 1 nested scroll view. Inside the ScrollView there are various elements including recycle view. I would like that the recycle view not scroll but scroll only the nested scroll view. I have disabled the scroll of recycle view in this mode
(recyclerView.setNestedScrollingEnabled(false);)
but the problem is that the nested scroll view not scrolling. Can you help me?
I attach the code below.

As i answered in comments
For Someone other facing same problem. This might help.
For some reasons ScrollView doesn't scroll when having ConstraintLayout inside it.
For Workaround we can use LinearLayout or RelativeLayoutinstead of ConstraintLayout inside ScrollView. OR
As OP does put the ConstraintLayout inside Linear or Relative Layout does the trick.
According to Ali Ahmed's answer, a ScrollView doesn't scroll if you have a ConstraintLayout inside it. Well that's not true. I have been using ConstraintLayout inside ScrollView and everything works perfectly fine. Well the problem with the code that you posted is that you are using 0dpas the layout_height of your RecyclerView. 0dp means match_parent. You should be using wrap_content as your layout_height. So that the RecyclerView expands its height according to the elements in it. Doing so will make your code work fine.
I have a fragment containing a layout

But in the layout editor it is showing
How can I remove the spacing above?
The problem is with your Activity where you had inflated the Fragment. Actually, i tried it on My system and I'm Getting Proper result.
Check Your Activity's Layout where the FrameLayout is Used.
2nd Possbility
Check your May be Your Theme is Changing this . Check all the possibilities
Try the following code Replacing the ConstraintLayout after the Spinner
<android.support.constraint.ConstraintLayout
android:id="#+id/linearLayout2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#drawable/android_date_bgd"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
What happened to me was smiliar, a space on top that did not show in the editor.
The problem was not in the main layout file I was focusing on, I was displaying some fragments thru a viewpager and the margins on the editor for the pager were 0 so the editor preview did not showed a space on top. However the fragments that were being created/shown had of course a different layout file and in that layout there was a huge space on top because I erroneously thought centering the layout vertically was a good idea for some reason (mainly because I code at night before bed and sometimes im too tired lol). Since the layout height for the viewpager did not match the dimensions of the fragment I had some weird behaviors trying to position the elements of the main layout file.
I was facing a similar problem. By looking at the code snippet in the question I saw the similarity that we both have android:fitsSystemWindows set to True. By removing this android:fitsSystemWindows attribute, my space at the top was removed.
I'm my search the closest question was that: Scrollview inside constraint layout does not scroll to the bottom of the parent constraint
But there is no solution =|.
What I'm trying to do:
I have a constraint layout with 3 "parts": top bar, middle content and bottom button.
I want to put a scrollview only for the middle content. So if you scroll down and up you continuous to see the top bar and the bottom button
But this scroll view is not working, I think is something related with "match_parent" in the scrollview, but I can't put this option because as the scrollview is inside a Constraint Layout the size should be relative and if I put match parent it don't fill all spaces.
I'm using already:
fillViewport="true",
layout_constraintBottom_toBottomOf="parent"
Follow the code, scroll view name: "scrollview2"

Well, I just found the solution with a friend, first I think about delete this, but since other people maybe have the same problem here is the solution:
I just remove all guidelines and build again, connecting the elements without using so many guidelines.
Was a little bit of lucky, because I did this to fix when change the orientation.
You need to create a chain with the following constraints
in the top bar:
app:layout_constraintBottom_toTopOf="#+id/scrollView2"
app:layout_constraintTop_toTopOf="parent"
in the middle content:
app:layout_constraintBottom_toTopOf="#+id/needs_search_save_btn"
app:layout_constraintTop_toBottomOf="#+id/actionbar"
in the bottom button:
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="#+id/scrollView2"
