如何设置FrameLayout高度以匹配子组件之一

FrameLayout frameLayout = findViewById(R.id.frameLayout);
View childView = findViewById(R.id.childView);

int childHeight = childView.getHeight();
FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) frameLayout.getLayoutParams();
layoutParams.height = childHeight;
frameLayout.setLayoutParams(layoutParams);

<FrameLayout
    android:id="@+id/frameLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
        android:id="@+id/childView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

<FrameLayout
    android:id="@+id/frameLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
        android:id="@+id/childView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <View
        android:id="@+id/childView2"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

</FrameLayout>
