Please please please do not use Display to do your layout. This tells you the raw size of the display; it is not directly associated with the UI.
The correct way to do this kind of stuff, always, is to do the layout during the layout pass. Please don't skimp on this. It is VERY IMPORTANT that you participate in the framework in the right way here, using the size information available in the view hierarchy as part of layout, to make sure you do the right thing!!! Otherwise you can expect to run in to problems in the future as you encounter devices with new and interesting kinds of screens. We do a lot of work in the framework to help applications deal with this, but if you go behind its back with Display and otherwise don't participate as a good citizen, it can't help and you will have troubles. Also, if you just want to find out whether you are running on a portrait or landscape orientation, please just use getResources().getConfiguration() and look at the orientation there. Again, Display is a low-level facility and not what you want. DO NOT USE IT. Thanks.
