I just updated my Android Studio to latest 3.0 and then the Layout Preview is not working anymore. I have tried open up different projects and they all have the same render issues. As I checked, I don't see any compile errors or gradle issues. So far, I tried

The following attached screenshot shows that some classes cannot be initiated but I dont get why and how to fix them. Thank you very much. Any hints could help.

更新:Android Studio 3.0中的渲染错误似乎有重复的案例布局编辑器 但我的问题略有不同.上述链接问题的解决方案是通过澄清 Base.Theme.AppCompat.Light.DarkActionBar 下的父主题来将主题修改为更具体的主题.但是，我什至没有 ActionBar，所以我正在寻找 Theme.AppCompat.NoActionBar 的解决方案.

Updates: It seems there is a duplicate case at Render error in Android Studio 3.0 Layout Editor but mine problem is slightly different. The solution for above linked issue is to modify the theme to a more specific one by clarifying parent theme under Base.Theme.AppCompat.Light.DarkActionBar. However, I don't even have an ActionBar so I am looking for a solution for Theme.AppCompat.NoActionBar.

在更新到 3.0 之前，一切正常.我想知道我是否需要更改部署SDK/版本.

Before updating to 3.0, everything is fine. I wonder if I need to change deployment SDK/Version.

推荐答案

好的，我试图探索所有可能的解决方案，但没有成功.我终于通过更改部署 SDK/版本来解决这个问题.我全部更改为 26，它解决了我的问题.随着我测试的版本越来越低，似乎只有 26 版才能工作.

OK, I tried to explore every possible solution but no work. I finally figured it out by changing the deployment SDK/Version. I changed all to 26 and it fixed my problems. As I tested version lower and higher, it seems only ver 26 can work.

android {
 compileSdkVersion 26
 buildToolsVersion '26.0.2'
...
 defaultConfig {
  targetSdkVersion 26
...
 }
}
...
dependencies {
  compile 'com.android.support:appcompat-v7:26.0.0'
  compile 'com.android.support:design:26.0.0'
  compile 'com.android.support:support-v13:26.0.0'
  compile 'com.android.support:support-v4:26.0.0'
  compile 'com.android.support:palette-v7:26.0.0'
...
}

因此，如果 Android Studio 3.0 中的渲染错误的解决方案布局编辑器 不适合您.你可以试试 26.让我知道.

So if the solution at Render error in Android Studio 3.0 Layout Editor does not work for you. You can try 26. Let me know.
