导入 graphview 时 gradle 中的库版本错误

Question

我有 android studio 3.3.2，我的目标是导入 GraphView 库，但事实证明它给了我一个错误，所有库必须具有相同的版本规范，我提出错误图片

错误工具提示信息

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 27.1.1. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:support-media-compat:27.1.1 less... (Ctrl+F1) Inspection info:There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion).

Answer 1

而不是这个

 compileSdkVersion 28 

 targetSdkVersion 28

 implementation 'com.android.support:appcompat-v7:28.0.0'

 implementation 'com.android.support:design:28.0.0'

使用

 compileSdkVersion 27

 targetSdkVersion 27

 implementation 'com.android.support:appcompat-v7:27.1.1'

 implementation 'com.android.support:design:27.1.1'

GraphView库支持库版本为27。所以你可以降级你的库版本。如果您不想降级，则将 GraphView 作为模块导入，并在 build.gradle 文件中更改为 compileSdkVersion 28 和 targetSdkVersion 28
