解决方法
用列表视图说这样：
ListView<String> listView =new ListView<String>();
从ListView中获取选定的元素：
listView.getSelectionModel().getSelectedItem();
跟踪(聆听)列表视图选择中的更改：
listView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<String>() {
@Override
public void changed(ObservableValue<? extends String> observable,String oldValue,String newValue) {
System.out.println("ListView selection changed from oldValue = "
+ oldValue + " to newValue = " + newValue);
}
});
