无法解决：支持片段   打开文件

您需要添加支持库 com.android.support:support-fragment:28.0.0

尝试从中安装。您可以尝试通过以下路径安装它：

Android Studio，进入菜单文件>项目结构（Ctrl + Alt + Shift + S） 选择应用，然后选择依赖项，然后搜索 com.android.support:support-fragment:28.0.0

如果这不起作用，请尝试以下方法：

allprojects {
repositories {
    maven {
        url "https://maven.google.com"
       }
     }
   }

让我知道这是否可行。
