Exclude Certain Elements From Being Animated In Android Layout Transitions

I have a question regarding the android layout transition framework. In particular i want to achieve an effect that a certain part of an layout slides down or up depending on the v

Solution 1:

I know it's late but hope it can help someone. Since android:animateLayoutChanges is the property of the direct parent, you can wrap your View/Layout in a FrameLayout (or some other ViewGroup) and set android:animateLayoutChanges="false" on the new parent.

Solution 2:

To avoid unwanted animations you can remove the animate layout changes by code when needed, something like this:

//removing the animate layout changes to prevent the default animation for the newly added items
parentLayout.setLayoutTransition(null);

/* do some logic to add the new views *///add the animate layout changes back so the over changes will be still animated
new Handler().post(() -> {parentLayout.setLayoutTransition(new LayoutTransition());});
