推荐答案

这是由于使用了 alpha 版本 SDK 28

我们需要更改应用文件中build.gradle"中的android { ... }
compileSdkVersion 28 到 compileSdkVersion 27
targetSdkVersion 28 到 targetSdkVersion 27

We need to change the android { ... } in "build.gradle" in app file
compileSdkVersion 28 to compileSdkVersion 27
targetSdkVersion 28 to targetSdkVersion 27

此外，尝试更改实现，例如
实现'com.android.support:appcompat-v7:28.0.0-alpha3'到
实现'com.android.support:appcompat-v7:27.1.1'

Also, try to change implementations like
implementation 'com.android.support:appcompat-v7:28.0.0-alpha3' to
implementation 'com.android.support:appcompat-v7:27.1.1'

希望这有效！

对于 Android Studio v3.1.*，我们还需要更改:
实现 'com.android.support:design:28.0.0-alpha3' 到
实现'com.android.support:design:27.1.1'

For Android Studio v3.1.*, in addition we need change:
implementation 'com.android.support:design:28.0.0-alpha3' to
implementation 'com.android.support:design:27.1.1'
