In particular, the hierarchy of XML nodes, for example. DrawerLayout-> RelativeLayout-> AutoComplete ImageButton is not working properly. The list of offers contains invalid items. For instance. android:src not displayed inside ImageButton while it should be.
Invalid offers: 
On the other hand, if the hierarchy is RelativeLayout-> RelativeLayout-> ImageButton, then everything is fine.
Valid offers: 
I already tried:
- reopening the xml file - no effect
- re-design - no effect
- restart eclipse - no effect
