Setting android:animateLayoutChanges programmatically

Question

I am creating linearLayouts programmatically and would like them to fade in and out when the visibility is set to visible/gone.

I can set

android:animateLayoutChanges="true"  

in the xml-file, but since I am creating the views programmatically, I need to set it programmatically. How can I do that?

Answer 1

Use this code:

container.setLayoutTransition(new LayoutTransition()); 

or

LayoutTransition lt = new LayoutTransition(); lt.disableTransitionType(LayoutTransition.DISAPPEARING); container.setLayoutTransition(lt); 

Answer 2

To disable the fade-out effect try this:

LinearLayout layout = (LinearLayout) findViewById(R.id.test_layout); layout.setLayoutTransition(null);
