ConstraintLayout 2 TextView first one ellipsize

UPDATE

I achieved this behavior with following things:

txtFullName

android:layout_width="0dp"
app:layout_constraintWidth_default="wrap"

btnFollow and btnUnfollow

android:layout_width="0dp"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintWidth_default="wrap"
app:layout_constraintWidth_min="wrap"

ORIGINAL QUESTION

I have an XML layout which is parent layout is ConstraintLayout and inside

       -- txtFullName -- (btnFollow | btnUnfollow ) --       
Avatar ----------------------------------------------- btnPrimaryAction
       -- txtTitle -----------------------------------

I want this:

Long txtFullname okay

But I got this with my xml

Long txtFullName not okay

When txtFullName is long, it is overlapping btnFollow or btnUnfollow and these buttons are not showing on screen. I want txtFullName to be ellipsize when it is long. I tried to use ConstraintLayout's Flow but it didn't work well too.

My layout constraints can be shown below.

</androidx.constraintlayout.widget.ConstraintLayout>

How can I achieve this UI?

You need a couple of attributes:

  • In txtFullName to have match constraints width, so that its width can't exceed the barrier, and allow it to add the ellipsize just before the barrier.

    android:layout_width="0dp"

  • In btnFollow & btnUnfollow use layout_constraintWidth_min with wrap value so that they can make sure that they always take the preference of wrapping their contents even when the width matches the constraints with 0dp

    app:layout_constraintWidth_min="wrap"

As suggested in the other answer either you can either set layout_width to 0dp in your txtFullName or you can add the following flag too in your txtFullName

app:layout_constrainedWidth="true"

As follows

<TextView
        android:id="@+id/txtFullName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginEnd="2dp"
        android:ellipsize="end"
        android:maxLines="1"
        app:layout_constrainedWidth="true"
        android:textColor="?attr/textColorMarineBlue"
        app:layout_constraintEnd_toStartOf="@id/textButtonBarrierStart"
        app:layout_constraintStart_toEndOf="@id/imgAvatar"
        app:layout_constraintTop_toTopOf="parent"
        tools:text="Long Full Name is overlapping btnFollow" />

You are on the right track. Use

layout_width="0dp"

instead of layout_width="wrap_content" for the TextView with id txtFullName as well.
