xmlns:app="http://schemas.android.com/apk/res-auto"

app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintWidth_percent="0.5"
app:layout_constraintHeight_percent="0.5"

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintWidth_percent="0.5"
        app:layout_constraintHeight_percent="0.5"
        app:srcCompat="@drawable/your_image" />

</androidx.constraintlayout.widget.ConstraintLayout>
