How to make view "wrap_content but not larger than" with ConstraintLayout?

Question

I'm having 3 view in a row: title, version and imageview (working as button):

1. title should be wrap_content but respecting the following rules
2. version should be wrap_content, to right of the title and to left of imageview
3. imageview has fixed size and is at right top corner of the parent

The problem is if title is too large, the version is moved to right and rule "version is to the left of imageview" is not respected:

So i need to limit title width and make version visible and not moved to the right.

Here is XML:

<?xml version="1.0" encoding="utf-8"?>

</android.support.constraint.ConstraintLayout>

PS 1. layout_width="0dp" + app:layout_constraintWidth_default="wrap" seems to be exactly what i need ("wrap_content but not breaking the constraints") but it does not work (still larger than required):

<TextView
        android:id="@+id/LibraryWithVersionItem.title"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:ellipsize="middle"
        android:textColor="@color/mySecondaryDarkColor"
        android:textSize="@dimen/fontSize18"
        android:textStyle="bold"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintWidth_default="wrap"
        tools:text="ExampleLibrary 01234567890123456789012345"

PS 2. Setting min constraint width for the version (app:layout_constraintWidth_min="60dp") does not help too - it's invisible as it's moved too right.

Answer 1

Title and version should be in the chain and app:layout_constraintWidth_default="wrap" used:

</android.support.constraint.ConstraintLayout>

I've tried to align version to title baseline but if the title is 2 or more lines it's aligned to the first line and it's not desired. So i had to align version to title bottom and hardcode title -3 bottom padding.

However, it looks as desired in Android Studio:

but on hardware device it looks different:

When analyzing in Layout Inspector i can see title width is calculated wrong:

Probably it's side effect of using it in RecyclerView but anyway...

Answer 2

You want to set android:layout_width="0dp".

Using wrap_content, the view will grow infinitely with the content. By using 0dp and setting its constraints, the view will have the maximum size as default, and the content will grow inside it reaches the limit.

---

Using android:layout_width="wrap_content"

---

Using android:layout_width="0dp"

---

From here-on, do your magic. You can set the TextView's android:maxLines="1" and android:ellipsize="end", adding three dots when reaching the maximum size.
