如何将布局插入到另一个frameLayout中？

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

    <!-- Parent FrameLayout content here -->

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

        <!-- Child FrameLayout content here -->

    </FrameLayout>
</FrameLayout>

FrameLayout parentFrameLayout = findViewById(R.id.parentFrameLayout);
FrameLayout childFrameLayout = findViewById(R.id.childFrameLayout);

View layoutToInsert = LayoutInflater.from(this).inflate(R.layout.layout_to_insert, null);
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);

childFrameLayout.addView(layoutToInsert, layoutParams);
