我的应用程序使用此config.java来构建抽屉菜单，它实际上是静态菜单，但我进行了一些自定义并使其从json获取数据，但是在数据显示后它没有显示在抽屉上但是当我触摸时数据出现在抽屉上的一个项目我觉得它自己刷新了如何在数据采取时自动刷新？

Answer 1

请注意，您从AsyncHttpClient获取抽屉数据。它将在稍后执行并调用onSuccess（）。所以function configuration（）只返回TümVideolar，Facebook，Twitter，Favoriler，Oynatma Listeleri。

为此，请在onSuccess（）结束时调用菜单适配器的notifyDataSetChanged（）。

JSON的抽屉菜单不显示项目
