Android Studio布局编辑器未显示任何建议 [英] Android Studio layout editor does not show any suggestions
问题描述
我创建了新的XML文件temp.xml，当我尝试在其中添加文本视图时，没有显示任何建议.当我单击TextView时，TextView被添加而没有正文.然后，我从其他文件中复制粘贴了一些代码，并尝试将大小，颜色等提供给TextView编辑器，但没有给出任何建议(请查看下面的图像链接)，我不知道我的布局编辑器或Android Studio是否存在任何问题. (我已经尝试过使Invalidate cache/Restart解决方案无效，)
如果你们过去曾经遇到过这个问题，请帮助我.先感谢您.
