当我在启动画面之后点击其中一个按钮时，加载将永远持续进行，并且无法在屏幕上显示数据。我已经使用各种库进行构建，并没有错误，因为应用程序启动，但这里是加载屏幕的屏幕截图，它没有给出显示加载数据的期望输出。 
我logcat的是：真正的 “结果”：Android应用程序启动但无法加载数据并且加载过程会一直持续

您可以发表相关的日志和代码吗？从你的问题来看，你做了什么来实现这种行为并不清楚。 –
使用Log.i（key，value）来检查您是否确实从服务器获得任何回应。在您从Async调用中获取API响应的地方使用它。 如果你仍然得到你的价值，那么检查你的adpaters是否获得了实际价值，无论你是否调用它们，以及随后的viewHolder。 –
你正在努力从响应解析值“成功”，但你得到这个作为响应{“错误”：真，“结果”：“类别未找到”}，因此错误 –
