如何正确使用ViewStub的Kotlin Android扩展？

Question

扩展是否具有调用膨胀视图的魔力？据我所知,我应该打破代码和呼叫的和谐findViewById

目的是layout_ongoingView在某个时候使布局膨胀,并根据场景再次隐藏和显示

<ViewStub
    android:id="@+id/viewStubOngoing"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inflatedId="@+id/ongoingView"
    android:layout="@layout/layout_ongoingView" />

和代码

override fun hideOngoingPanel() {
    if (viewStubOngoing !is ViewStub) {
        findViewById(R.id.ongoingView).visibility = View.GONE
    }
}

override fun showOngoingPanel() {
    if (viewStubOngoing !is ViewStub) {
        findViewById(R.id.ongoingView).visibility = View.VISIBLE
    } else {
        viewStubOngoing.inflate()
    }
}
