Max width in Constraint Layout

Question

I am working on a chat app. I want the message (text view) to always start 20px from the left of the screen. When the message is short, the text view's width is wrap content. But when the message is long, the text view will reach 50px to the right of the screen. How to achieve it.

short text

long text

Answer 1

Use app:layout_constrainedWidth="true" with app:layout_constraintHorizontal_bias="0"

The following works for me:

<TextView
        android:text="sampleskdjfalksfasdkfjakllksdajfkljaskfdlasdjfklajdfklajkf"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginTop="50dp"
        android:layout_marginStart="20dp"
        app:layout_constrainedWidth="true"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0"
        android:layout_marginEnd="50dp"
        app:layout_constraintStart_toStartOf="parent"
        android:background="#666"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
