I'm currently playing with the ConstraintLayout, what an awesome tools!
But... there is obviously a but...
This layout correspond to a childrenView layout inside an expandableListView.
The problem happen when i have long text, like this one.
We can see the chipcloup going over the text while the constraint indicate that it shouldn't be.

In that case the DiscreteScrollView has a GONE visibility, but even when it's visible, the chipcloud also goes in front of the DiscreteScrollView.

I'm using constraintlayout and I have an activity that is a user profile. and it includes a picture of user. when I code xml layout. I can see the picture in preview window inside android studio the image is a png image. I have tried changing the image to one of the android studio avatar. still doesn't work. however, when I run the app the picture is not displaying. does anyone know why this happen?

From: https://developer.android.com/studio/write/tool-attributes
Android Studio supports a variety of XML attributes in the tools
namespace that enable design-time features (such as which layout to
show in a fragment) or compile-time behaviors (such as which shrinking
mode to apply to your XML resources). When you build your app, the
build tools remove these attributes so there is no effect on your APK
size or runtime behavior.
So the attribute:
tools:src="#drawable/prifile_pic"
is valid only for design-time.
It is not compiled in the APK and you will not see the image when you run the app.
Change it to:
app:srcCompat="#drawable/prifile_pic"
Do any of your ImageViews display the intended images? Your profile pic ImageView is using tools:src while others are using app:srcCompat
I just noticed a potential typo too -
tools:src="#drawable/prifile_pic" <<--- supposed to be profile_pic?
Are you getting any exception in your android studio log-cat, like image not found? As Stitches wrote in above comment --> typo error for prifile_pic, please check you drawable name is same in your xml layout and image name in drawable folder.
I want the ImageView positioned to the far right
look at the picture the first row have a white color ImageView how to make it stick to the right. Using the Android layout inspector the ImageView show to have empty space on both right and left side. Is there some Gravity left something I can use?

When using ConstraintLayout I find it better to preview in blueprint mode. If you do so you'll be able to see the circle indicating the constraints in each element:
TO use it just click and drag the arrow to the view you want this element to me constrained to. In you case you'll use the top and right constraints guides to position the image view to the top right in the screen.
Moreover, to have a parfectly squared image view you should set the width and height to be the sabe, if you have wrap content in one and 0dp in other it won't be perfectly squared but rather rectangular because one of the dimensions is allowed to grow freely.
I'm doing a simple list activity with the following components: an EditText, a RecyclerView, a ProgressBar and a Textview. Everything works really well, except for the RecyclerView which overlaps the EditText and goes "beyond" the screen bottom so the last item is partially cut out (see the screenshots).
What an I doing wrong?

You are using android:layout_height="wrap_content" for RecyclerView
but it's looks like you need to limit height. Try it with android:layout_height="0dp". In this case it is equals to app:layout_constraintTop_toBottomOf="#+id/search_text" and app:layout_constraintBottom_toBottomOf="parent"
I had the exact same problem, and adding
app:layout_constrainedHeight="true"
to the RecyclerView solved it.
try following, you have to set topConstraint of recyclerview to edittext
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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" >
<EditText
android:id="#+id/search_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:hint="search by tag..."
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ProgressBar
android:id="#+id/gallery_progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/search_text" />
<android.support.v7.widget.RecyclerView
android:id="#+id/gallery_list"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/search_text" />
<TextView
android:id="#+id/gallery_error"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/search_text"
tools:text="error" />
</android.support.constraint.ConstraintLayout>
Output :
For some reason adding proper constraints and setting height as 0dp did not work for me(Even though it should work for most of the cases)
So I added a frame layout as the parent of the recycler view and set the height and width of recycler view as match_parent added the constraints to the frame layout.
This stopped the overlapping issue
In RecyclerView add this:
app:layout_constraintStart_toEndOf="#+id/search_text"
You pass the same id to each view, modify your code with this.

Happy coding!!
Just use
app:layout_constraintVertical_bias="0.0"
in recyclerView tag.
hope this helps.
Change your XML file to below code.

Try this and let me know if this worked for you.
I face this problem when I am building a music player app I solve my problem to give the height of recyclerview 0dp IDK how it's work but my problem was solved
I am using a RecyclerView and this is the code for activity_main:
<?xml version="1.0" encoding="utf-8"?>

Basically, there is the Title at the top, the link, and the pubDate. Then there is the image, and then the description. Besides the image (ImageView), all the others are TextViews.
The problem is that when I load an image from an RSS feed to the ImageView, and the thumbnail is gone, the ImageView overlaps with the description TextView. I have searched everywhere but I can't seem to find any solution. I understand that the bitmap changes its size and not the ImageView, and most likely that's what's causing the overlap, but I can't find a way to fix it.
Thank you so much in advance.
Screenshot:

Remove the following line from description:
app:layout_constraintBottom_toBottomOf="parent"
This will effectively move the description view below the image. I have just tested it out and it is working.
I hope this helps.
This is the first screenshot, where everything is working fine with a placeholder background.
This is the second screenshot, where the two ImageButtons don't display anymore.

You can try YourImageButton.bringToFront() to the image butons after changing the ImageView source.
