How can I make the image (the actual image itself, not just ImageView) always have the same height as LinearLayout?

        <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_height="match_parent"
            android:layout_width="match_parent">

            <ImageView
                android:id="@ id/image"
                android:layout_width="match_parent"
                android:layout_height="100dp"
                android:src="@drawable/myimage"/>

            <LinearLayout
                android:id="@ id/textview_layout"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:orientation="vertical">

                <TextView
                    android:id="@ id/tv2"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"/>

                <TextView
                    android:id="@ id/tv2"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content" />

            </LinearLayout>

        </androidx.constraintlayout.widget.ConstraintLayout>
