How to add and remove layout behavior programmatically to LinearLayout

问题

You can add the app:layout_behavior="@string/appbar_scrolling_view_behavior" behavior to a LinearLayout in the XML declaration but I haven't found a way to do the same in code. With a CoordinatorLayout you can call CoordinatorLayout.LayoutParams.setBehavior() but this method isn't available on LinearLayout.LayoutParams. Is there a way to do something similar for LinearLayout?

回答1:

You're misunderstanding LayoutParams concept a bit.

LayoutParams object is related to the enclosing ViewGroup, not to the modified ViewGroup itself.
