更改主题时呈现问题
Rendering Problems while changing the theme
我是 Appdevelopment 的新手,我试图在 Android Studio 1.4.1(最新)Windows 10 x64 上更改我的应用程序的主题,但我总是遇到异常,这里是我做什么:(是的,我现在已经有很多问题,但我找不到答案)
- 开始项目(名称:TEST)
- 对于 Phone 和平板电脑(最小 SDK:API 15 Android 4.0.3 IceCreamSandwich)
- 选择空白Activity(名称:主要Activity)
- 转到 activity_main.xml -> 设计视图
- 选择 Nexus 4; API23; Holo Light / Holo Dark / Material Light / Material Dark; (API 和 Phone 没关系 => 尝试了很多)
- 异常:
渲染问题
无法实例化以下 类:
- android.support.design.widget.CoordinatorLayout
- android.support.design.widget.AppBarLayout

怎么了??我使用预制的东西但它不起作用? -_- 不酷。
请帮忙! -Minding
尝试为项目选择更高的最低 SDK(Lollipop 或 Marshmallow)
如果您确实需要较旧的最小值,请尝试创建一个空 activity 或根本没有 activity 的项目,然后从那里开始。
尝试更换
android:theme="@style/AppTheme.AppBarOverlay"
与
android:theme="@style/Theme.AppCompat.Light"
里面CoordinatorLayout
