android无法静态显示ui效果。
Missing styles. Is the correct theme chosen for this layout?
Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.Failed to find style 'textViewStyle' in current theme
採用的解决方法例如以下：
把layout预览界面右上角有个Theme的选择项，默觉得notitle，把它改成设定为android曾经默认的Theme.black.
