Thanks for any suggestions.

It might be late to answer the question but anyway, the problem might be with the line following constraint on viewpager :-
app:layout_constraintBottom_toTopOf="#id/imageLike"
Remove the line.
Exactly can not explain why this happens but you should try it.

below screenshot which I want to achieve

Wrap the views with another Viewgroup (say ConstraintLayout again) and set app:layout_constraintStart_toStartOf="parent" and app:layout_constraintEnd_toEndOf="parent" as constraints to this viewgroup. Said view will then be centered horizontally.

I messed up the ImageButtons a little, please fix the drawables and the color.
Edit 2: for some reason, another closing tag won't show in the code section here. make sure to add another ConstraintLayout closing tag right at the end.

Edit 3: Here's a clean take to it.This one should do what you want. Though you have to tweak the margins the way you want them! Again the closing tag ... I don't know why it won't appear here!

If you want to move your views that are on the left side of the screen to the right part of the screen simply change your constraints like this:
Replace your constraints, your views will get constraint to your guideline from the left and to the right side on the screen as the right constraint.
Do it like this:

android:contentDescription="TODO"
android:src="#drawable/ic_share"
app:layout_constraintBottom_toBottomOf="#+id/articleTime"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/articleFavorite"

And it will look like this:

Constraint Layout is causing views to overlap

I'm trying to create a view in Android using ConstraintLayout but I'm having a lot of issues with views overlapping or being pushed off of the screen. I think a lot of it might be because I'm so used to iOS constraints and I'm thinking in terms of them. Here is my code:
<?xml version="1.0" encoding="utf-8"?>

app:layout_constraintGuide_percent="0.875"/>

app:layout_constraintRight_toRightOf="parent"
app:src="#drawable/start"
app:text="#string/get_started"/>
</android.support.constraint.ConstraintLayout>
The first image is what I'd like to see, and the second is what I'm getting.

Try changing
<Button style="#style/RoundedButton"
android:id="#+id/resetButton"
android:text="#string/reset"
app:layout_constraintBottom_toTopOf="#id/startButton"
app:layout_constraintLeft_toLeftOf="#id/previousButton"
app:layout_constraintRight_toRightOf="#id/previousButton"
app:layout_constraintTop_toBottomOf="#id/previousButton"/>
To
<Button style="#style/RoundedButton"
android:id="#+id/resetButton"
android:text="#string/reset"
app:layout_constraintBottom_toTopOf="#id/startButton"
app:layout_constraintLeft_toLeftOf="#id/previousButton"
app:layout_constraintRight_toRightOf="#id/previousButton"
app:layout_constraintTop_toBottomOf="#id/newButton"/>

Use below layout:

Horizontally center TextView inside ImageView and there is another view next to Imageview

Hi I want to build UI as below
I want to center imageview above textview at the same time there is another view next to imagview dash line I am not able to do this.
Currently I am using RelativeLayout. Any idea how this can be done?
Following is XML
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true">
<ImageView
android:id="#+id/ivnumberfill"
android:layout_width="16dp"
android:layout_height="16dp"
app:srcCompat="#drawable/ic_otp_fill" />
<ImageView
android:id="#+id/ivfirstdiv"
android:layout_width="76dp"
android:layout_height="2dp"
android:layout_alignBottom="#id/ivnumberfill"
android:layout_alignTop="#+id/ivnumberfill"
android:layout_toRightOf="#id/ivnumberfill"
android:src="#drawable/stroke_divider" />
<ImageView
android:id="#+id/ivotp"
android:layout_width="16dp"
android:layout_height="16dp"
android:layout_toRightOf="#+id/ivfirstdiv"
app:srcCompat="#drawable/otp_process_circle" />
<ImageView
android:id="#+id/ivseconddiv"
android:layout_width="76dp"
android:layout_height="2dp"
android:layout_alignBottom="#id/ivotp"
android:layout_alignTop="#+id/ivotp"
android:layout_centerVertical="true"
android:layout_toRightOf="#id/ivotp"
android:background="#drawable/stroke_divider" />
<ImageView
android:id="#+id/ivprofile"
android:layout_width="16dp"
android:layout_height="16dp"
android:layout_toRightOf="#+id/ivseconddiv"
app:srcCompat="#drawable/otp_process_circle" />
<TextView
android:id="#+id/tvnumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/ivnumberfill"
android:alig="#id/ivnumberfill"
android:text="Mobile Number"
android:textColor="?colorAccent"
android:textSize="11sp" />
</RelativeLayout>

I would recommend using ConstraintLayout, you should really learn it and use it instead of Relative Layout, it's more flexible and less computation consuming. Here is my layout, is it also more flexible - you can just move guideline and everything moves with it.

Well, you can use Constraint layout for this just simple drag and drop and it will give you your desired layout.

How to apply divider or view in Constraint layout

I want to apply a divider at some places in Constraint layout but when I do it by simple view, the whole layout get shifted to the top and everything gets merged. I want to use only constraints layout for the whole design.
<TextView
android:id="#+id/textView16"
android:layout_width="0dp"
android:layout_height="18dp"
android:text="TextView"
app:layout_constraintLeft_toRightOf="#+id/imageView11"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintHorizontal_bias="1.0"
android:layout_marginTop="13dp"
app:layout_constraintTop_toBottomOf="#+id/textView14"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_marginBottom="8dp"
app:layout_constraintVertical_bias="0.0"
android:layout_marginStart="8dp"
android:layout_marginEnd="8dp" />
<TextView
android:id="#+id/textView20"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="parent"

android:layout_marginLeft="8dp"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintVertical_bias="0.0"
android:layout_marginRight="8dp"
android:layout_marginStart="8dp"
android:layout_marginEnd="8dp" />
<View

android:layout_height="2dp"
android:background="#android:color/background_dark"
tools:layout_editor_absoluteY="98dp"
android:id="#+id/view"
tools:layout_editor_absoluteX="0dp" />
<TextView
android:id="#+id/textView21"
android:layout_width="wrap_content"
android:layout_height="17dp"
android:layout_marginBottom="8dp"
android:layout_marginRight="8dp"
android:text="Nivedita Parmar"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHorizontal_bias="0.025"

app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#+id/view"
app:layout_constraintVertical_bias="0.035"

Please give some idea regarding this.
Thanks in advance..

Check out Guideline. I've found it to be useful when working with Constraint Views.
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.constraintlayout.widget.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/guideline"
app:layout_constraintGuide_begin="100dp"
android:orientation="vertical"/>
<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button"
app:layout_constraintLeft_toLeftOf="#+id/guideline"
android:layout_marginTop="16dp"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
