以下代码有效，但是当我从“男性”更改为“女性”时，反之亦然，cbSpouse会加载新的项目。正确的数据被加载。但是问题是，如果我单击cbSpouse中的向下箭头，则需要等待几分钟，然后才能看到下拉菜单。没有数据库交互，所有必需的数据已经位于“可观察”列表中。
ObservableList<String> GenderOptions = FXCollections.observableArrayList("Male", "Female");
cbGender.getItems().clear();
cbGender.setItems(GenderOptions);
cbGender.setVisibleRowCount(GenderOptions.size());
cbGender.getSelectionModel().selectFirst();
cbGender.valueProperty().addListener(new ChangeListener<String>() {
@Override
public void changed(ObservableValue ov, String t, String t1) {
System.out.println("Change Listener for cbGender - oldValue "+t+" new value"+t1);
if ((t1.equals("Male")) || (t.equals(null))) {
cbSpouse.setItems(myMainApp.getFemaleSpouses());
if (thisPerson.getPhoto() == null) {
thePicture.setImage(defaultMale);
}
} else {
cbSpouse.setItems(myMainApp.getMaleSpouses());
if (thisPerson.getPhoto() == null) {
thePicture.setImage(defaultFemale);
}
}
cbSpouse.getSelectionModel().selectFirst();
}
});
//
myMainApp.getMaleSpouses（）中大约有300项实际上返回了Observable列表。
有人可以帮我吗？
谢谢。

答案 0 :(得分：-1)
这是较小的版本，效果很好。只需不断更改性别并单击“配偶”，就会出现新列表。

在此示例中，数据是经过硬编码的，并且在Main.java中，但是在其他版本中，数据是从 静态私有javafx.collections.ObservableList父亲= javafx.collections.FXCollections.observableArrayList（）; 静态私有javafx.collections.ObservableList Mothers = javafx.collections.FXCollections.observableArrayList（）;
在更改cbGender valueProperty之前，更早地从数据库加载ObservableList。
谢谢
