我＆＃39;使用SceneBuilder创建一个Java FX项目，当我试图处理onHiding和onHidden for fx日期选择器时，我遇到了争论类型不匹配（最后的异常消息）。
我已经在这里查看了答案：JavaFx Event argument type mismatch。
第一个解决方案对我不起作用，因为我需要在隐藏过程中和之后执行操作。我尝试了第二种解决方案，并且根据我的怀疑，它也没有起作用。
以下是FXML控制器：
import com.jfoenix.controls.JFXButton;
import com.jfoenix.controls.JFXCheckBox;
import com.jfoenix.controls.JFXDatePicker;
import com.jfoenix.controls.JFXRadioButton;
import com.jfoenix.controls.JFXTextField;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.ToggleGroup;
public class EditActionWindowController {
private Task task = null;

我的理解是onHiding处理程序和日期选择器的onHidden处理程序抛出了参数不匹配异常。非常感谢帮助。
答案 0 :(得分：0)
onHidden和onHiding属性为EventHandler<Event>，而不是EventHandler<ActionEvent>。因此，传递给处理程序方法的参数是Event的实例。当FXMLLoader检查您指定的方法时，它会看到参数类型为ActionEvent，因此会抛出异常。
只需将onHidden和onHiding处理程序方法的参数类型更改为Event：
@FXML
void currentDatePickerOnHidden(Event event) {
}
@FXML
void currentDatePickerOnHiding(Event event) {
}
@FXML
void eventualDatePickerOnHidden(Event event) {
}
@FXML
void eventualDatePickerOnHiding(Event event) {
}
