"ScrollView can host only one direct child" only in Landscape mode

Question

I'm trying to use ScrollView and it works fine in Portrait mode but doesn't in Landscape mode. When I start the app, everything's fine but when I turn my phone on the side I have the "ScrollView can host only one direct child" Exception.

Here is my XML code :

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
