title: where is designer view (the 'structure' tab) of the preference activity in android studio?
body: <p>in <strong>eclipse ADT plugin</strong> when i create a <strong>preference activity</strong> it provides two modes <strong>design view</strong> and the <strong>xml file</strong> of the preference activity. The design view had the tab name <strong>"structure"</strong> that provides the easy adding of values to attributes through certain input boxes. But in <strong>android studio</strong> i can create an android XML file to create an activity but i cannot find the designer view of the activity, the "structure" tab?</p>
