Error in the xml editor

#1

Hi,

I use the screen editor to built my app activity screens. And this has worked perfectly (appartement pickers) but it mainlevée worked. After few time I was wanting to add something extra, but unfortunately it does not work. I tried on both of the xml i have, but both are showing the same message:
Can not view the layout. Attempt to invoke interface method ’java.util.collection java.util.Map.Values() On a null object reference

But this happening in the aide editor, when i click on the small top right icon looking like small screen or picture, not at exécution. It works perfectly while executing.
Issue i have now is that i cannot update screens.

You mean the UI designer is not working…
Copied your code and it didn’t work, but I don’t know if you provided me the full xml content, cause I had to sorround it with a main linear layout and added the following tag xmlns:android=“http://schemas.android.com/apk/res/android”
Now it works, bit if after this doesn’t work for you it means it’s a bug in AIDE.

Here the code, give it a try
