Android 如何解决在firebase上存储数据后的问题？
我的问题类似于这个问题，但我的案例是关于Java上的firebase实时数据库。我添加了一项功能，将收藏夹添加到Firebase数据库中，但问题只是更换了工具栏上的“收藏夹”按钮。详细活动页面如下图所示 当我单击list recyclerview上的项目时，detail活动必须知道数据是否存储在节点favorite上。当我单击detailActivity工具栏上的favorite按钮时，数据已成功存储，但当我再次打开存储在favorit上的项目时，favorite按钮的颜色未更改，尽管它已存储在favorite节点上 这是我为“详细信息”活动尝试的代码 DetailEducationActivity.javaAndroid 如何解决在firebase上存储数据后的问题？,android,firebase,firebase-realtime-database,Android,Firebase,Firebase Realtime Database,我的问题类似于这个问题，但我的案例是关于Java上的firebase实时数据库。我添加了一项功能，将收藏夹添加到Firebase数据库中，但问题只是更换了工具栏上的“收藏夹”按钮。详细活动页面如下图所示 当我单击list recyclerview上的项目时，detail活动必须知道数据是否存储在节点favorite上。当我单击detailActivity工具栏上的favorite按钮时，数据已成功存储，但当我再次打开存储在favorit上的项目时，favorite按钮的颜色未更改，尽管它已存储
