有人对此有解决办法吗?谢谢.

Anybody have a fix for this? Thank you.

推荐答案

1. 首先将android studio更新为最新版本(测试版)1.3测试版. [使用菜单选项'来自Android Studio的'检查更新']

1. First update android studio to latest version (beta) 1.3 beta version. [Using menu option 'Check for updates' from android studio]

使用Android M预览呈现预览.

Render your preview using Android M preview.

如果找不到beta更新，请更改android studio设置( 更新 )，然后更新该补丁并使用M预览进行渲染

If you are not able to find the beta update change android studio settings(Updates), then update that patch and render with M preview
