Another Kotlin Extension solution

If your activity's view is declared in xml (ex activity_root.xml), open the xml and assign an id to the root view:

android:id="@+id/root_activity"

Now in your class, import the view using:

import kotlinx.android.synthetic.main.activity_root.root_activity

You can now use root_activity as the view.
