android xml 布局错误（黑掉了）Missing styles. Is the correct theme chosen for this layout?

发现在调整页面的时候 ，老是报以下错误，导致无法静态显示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

 

解决方法如下：

layout预览界面（Graphic Layout）,右上角有个Theme的选择项，默认为notitle，根据喜好随意设定值，我们这里设定为android以前默认的Theme.black.

或可选：Theme.Light.NotitleBar
