JavaFX初始屏幕按鈕onClick錯誤

我正在用JavaFX製作一個桌面應用程序，並且我製作了一個只顯示5秒的啓動畫面，5秒鐘後它顯示一個帶有按鈕的新舞臺，當我點擊按鈕時發送一個錯誤：JavaFX初始屏幕按鈕onClick錯誤

下面是JavaFX類

RootForm.java（閃屏）

package Forms; 

    import java.io.IOException; 
    import java.util.logging.Level; 
    import java.util.logging.Logger; 
    import javafx.animation.PauseTransition;

    import javafx.scene.paint.Color; 
    import javafx.stage.Stage; 
    import javafx.stage.StageStyle; 
    import javafx.util.Duration; 


    public class RootForm extends Application { 


@Override 
public void start(Stage stage) throws Exception { 
    Parent root = FXMLLoader.load(getClass().getResource("RootForm.fxml")); 

    Scene scene = new Scene(root); 
    stage.setScene(scene); 
    stage.initStyle(StageStyle.TRANSPARENT); 
    stage.show(); 
    scene.setFill(Color.TRANSPARENT); 
    stage.getIcons().add(new Image("/Images/8-512.png")); 

    PauseTransition delay = new PauseTransition(Duration.seconds(5)); 
    delay.setOnFinished(event -> { 
     try { 
      Stage mainStage = new Stage(); 
      Parent parent = FXMLLoader.load(getClass().getResource("Error.fxml")); 
      mainStage.setScene(new Scene(parent)); 
      mainStage.show(); 
      mainStage.getIcons().add(new Image("/Images/8-512.png")); 
      stage.hide(); 
     } catch (IOException ex) { 
      Logger.getLogger(RootForm.class.getName()).log(Level.SEVERE, null, ex); 
     } 
    }); 
    delay.play(); 
} 

/** 
* @param args the command line arguments 
*/ 
public static void main(String[] args) { 
    launch(args); 
}

}

RootForm.fxml（閃屏FXML）

 <?xml version="1.0" encoding="UTF-8"?> 

    <?import java.lang.*?> 
    <?import java.net.*?> 
    <?import java.util.*?>

Error.fxml（第二階段與按鈕）

<?xml version="1.0" encoding="UTF-8"?> 

<?import java.lang.*?>

    </children> 
    <stylesheets> 
    <URL value="@style.css" /> 
    </stylesheets> 
</AnchorPane>

ErrorController.java（第二階段應出現的）

package Forms; 

import java.net.URL; 
import java.util.ResourceBundle; 
import javafx.event.ActionEvent; 
import javafx.fxml.FXML; 
import javafx.fxml.Initializable; 
import javafx.scene.control.Button; 

/** 
* FXML Controller class 
* 
* @author User 
*/ 
public class ErrorController implements Initializable { 

    @FXML 
    private Button btnMain; 

    public void btnMainActEvent(ActionEvent event) throws Exception{ 

     System.out.println("U Shtyp!"); 

    } 
    /** 
    * Initializes the controller class. 
    */ 
    @Override 
    public void initialize(URL url, ResourceBundle rb) { 
     // TODO 
    }  

}

下面是截圖： Splash Screen

Second Screen with The Button

當我單擊第二個屏幕上的按鈕後，我得到該錯誤。任何人都可以幫我處理這個問題嗎？

是否確定按鈕點擊處理程序中的ActionEvent？嘗試使用javafx.scene.input.MouseEvent（你不能將MouseEvent投射到ActionEvent） – mrak

問題出在您在fxml中使用的onMouseClicked。它發送一個MouseEvent而不是ActionEvent。

您需要在fxml中使用onAction才能設置要在按鈕的fire (click) event上執行的操作。

<Button fx:id="btnMain" onAction="#btnMainActEvent" layoutX="107.0" layoutY="65.0" mnemonicParsing="false" prefHeight="112.0" prefWidth="101.0" text="Button" textFill="RED" />
