如何在Android中使用@ super注释修复超类没有公共方法
如何在Android中使用@ super注释修复超类没有公共方法
提问于 2016-06-07 06:21:10
我希望在我的Activity中显示3Activity，并在任何fragments中从json加载数据！我希望将每个json数据显示在一个片段中，但在我的应用程序中显示所有片段中的所有数据！(例如:，我希望将文章数据显示为文章片段，音乐数据显示为音乐片段等等)。
但是，在运行应用程序时，请向我显示以下错误：

如果您正在为您的构建使用proguard。确保这些行在android中的proguard配置文件中。(也适用于颤振项目)
-keepattributes *Annotation*
-keepclassmembers class ** {
@org.greenrobot.eventbus.Subscribe <methods>;
}
-keep enum org.greenrobot.eventbus.ThreadMode { *; }Stack Overflow用户

我也得到了同样的错误，在深入研究了一段时间后，我发现问题是由于错误的进口造成的。
我使用了进口com.google.common.eventbus.Subscribe；
而不是进口org.greenrobot.eventbus.Subscribe；
希望这对外面的人有帮助。
