你看 是不是 jar包 引用重复了 就是导入了相同的jar包 重复了 还有一个可能是xml文件中资源引用错误 反正 那个错误 0和1 就是这2种情况 具体那种 我记不得了

我也 遇到这个问题了，困惑了好久。 The android:elevation attribute is pretty new. It defines the lift of the view on which its applied. It's used in Material Design in the newest Android Versions. 意思是android:elevation这个参数是较新版本上才出现的。旧版本不支持？ 修改biuld.gradle 文件。 android { compileSdkVersion 25 buildToolsVersion '25.0.0'
