如何解决事件onEditCommit上的类型不匹配错误？
我在Fxml中使用了onEditCommit事件来在用户编辑后检索数据。
FXML代码 – ：
实现onEditCommit事件 – ：
public void editCommit_0(CellEditEvent event) { System.out.println("Value edited: On edit new value is "+event.getNewValue()); }
错误 – ：

请帮我解决这个错误，我应该在onEditCommit事件实现中放置什么类型。 我已打印柱单元值工厂
value_0.getCellValueFactory()
得到了

您的事件处理程序类型对我来说很好。 我的猜测是其他地方出现的类型不匹配。
样品
下面的示例演示了在使用FXML时设置提交事件处理程序。 对于冗长的道歉，这就是FXML的方式。
示例中的编辑提交处理程序是：
@FXML void commitValue(TableColumn.CellEditEvent event) { System.out.println("Commit: " + event.getNewValue()); }
其中Singluar只是TableView中用于样本的记录类的名称。
提交/ CommitController.java
import javafx.beans.property.SimpleStringProperty; import javafx.beans.property.StringProperty; import javafx.fxml.FXML; import javafx.scene.control.TableColumn; import javafx.scene.control.TableView; import javafx.scene.control.cell.PropertyValueFactory; import javafx.scene.control.cell.TextFieldTableCell; public class CommitController { @FXML private TableView table; @FXML private TableColumn value; @FXML void commitValue(TableColumn.CellEditEvent event) { System.out.println("Commit: " + event.getNewValue()); } public void initialize() { value.setCellFactory(TextFieldTableCell.forTableColumn()); value.setCellValueFactory(new PropertyValueFactory<>("value")); value.setEditable(true); table.getItems().setAll( new Singular("enie"), new Singular("meenie"), new Singular("minie"), new Singular("moe"), new Singular("just commit!") ); table.setEditable(true); } public static class Singular { private StringProperty value = new SimpleStringProperty(); public Singular(String value) { this.value.setValue(value); } public StringProperty valueProperty() { return value; } } }
提交/ CommitmentApp.java
import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.scene.Parent; import javafx.scene.Scene; import javafx.stage.Stage; import java.io.IOException; public class CommitmentApp extends Application { @Override public void start(Stage stage) throws IOException { stage.setScene(new Scene(createContent())); stage.show(); } private Parent createContent() throws IOException { FXMLLoader loader = new FXMLLoader(); return loader.load( getClass().getResourceAsStream("commit.fxml") ); } public static void main(String[] args) { launch(args); } }
commit.fxml
我做了这些改变。 在EditingCell.java中
public class EditingCell extends TableCell {
在EditController.jva中只添加了TableColumn
public void columnEdit(TableColumn.CellEditEvent event)
