When setting absolute values for android:layout_width and android:layout_height ImageView will be displayed with these dimensions.

If you want ImageView to fit the dimensions of the layout it should use match_parent and possibly android:adjustViewBounds="true" .

<ImageView
    android:id="@+id/imageView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:adjustViewBounds="true"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:srcCompat="@mipmap/ic_diag" />

If you want the image to fit the ImageView size you may need to use one of the android: scaleType . The type to use will depend on the size and shape of the image and the final result you want to obtain (with or without deformation, cropped image or not).
