我的问题是我的ListView没有在GUI上显示任何东西， 我添加了一个占位符来测试，它确实显示占位符文本，但除了我不能添加到列表中。JavaFX：ListView不显示在GUI中
我的目标是拥有所有客户帐户的列表，我已包含帐户类，我想在ListView中显示所有帐户ID。
由于某些原因，它不会工作，我试图只是输入随机数据只是为了看看是否这是问题，但仍然不是运气。
我在我的Main.class文件中有一个名为allAccounts的静态Set。
任何帮助将不胜感激，我搜索了近和远，因为我是新的这场斗争，理解为什么这是行不通的。

你先生真棒！我删除了初始化'list = new ListView <>（）;'现在全部按预期工作！我不知道它已经在fxml文件中初始化好了。我可以假设为TableView相同？ – J2FX
如果你通过'@ FXML'初始化某些东西，你不应该再次通过'new'初始化它，所以是的，你可以假定TableView是相同的。 – jewelsea
@jewelsea谢谢:)，因为当我删除注释它停止工作。 – J2FX
