问题描述

我是Appdevelopment的新手，正在尝试在Windows 10 x64的Android Studio 1.4.1(最新)中更改我的应用程序的主题，但是我总是会遇到例外，这是我的工作:(是的，我现在在那儿已经有很多问题了，但我找不到答案)

  1. 开始项目(名称:TEST)
  2. 用于手机和平板电脑(最低SDK:API 15 Android 4.0.3 IceCreamSandwich)
  3. 选择空白活动(名称:MainActivity)
  4. 转到activity_main.xml->设计视图
  5. 选择Nexus 4； API 23； Holo Light/Holo Dark/Material Light/Material Dark ； (API和电话没关系=>尝试了很多)
  6. 例外:

渲染问题

无法实例化以下类:

  • android.support.design.widget.CoordinatorLayout
  • android.support.design.widget.AppBarLayout

提示:[...]

解决方案

尝试为项目(Lollipop或棉花糖)选择更高的最低SDK

如果您确实需要更高的最低要求，请尝试创建一个活动为空或完全没有活动的项目，然后从那里开始.

I'm new to Appdevelopment and trying to change the Theme of my app in Android Studio 1.4.1 (latest) on Windows 10 x64, but I always get exceptions, here is what I do: (yes, I now there are already many questions, but I couldn't find an answer)

  1. Start Project (name: TEST)
  2. For Phone and Tablet (min. SDK: API 15 Android 4.0.3 IceCreamSandwich)
  3. Choose Blank Activity (name: MainActivity)
  4. Go to activity_main.xml -> design view
  5. Choose Nexus 4; API 23; Holo Light / Holo Dark / Material Light / Material Dark; (API and Phone doesn't matter => tried a lot)
  6. EXCEPTION:

Rendering Problems

The following classes could not be instantiated:

  • android.support.design.widget.CoordinatorLayout
  • android.support.design.widget.AppBarLayout

解决方案

Try choosing higher minimum SDK for the project (Lollipop or Marshmallow)

If you really need older minimum, try creating the project with an empty activity or no activity at all and start from there.
