如何使影像（實際影像本身，而不僅僅是ImageView）始終具有與 相同的高度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>
