我覺得主要是紅色部分那裏需要解決
-------------------------------
以下為主程式:
package JavaFXAppTest;
import javafx.fxml.FXML;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class MyFXML extends Application {
@Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("sms.fxml")); //載入fxml檔，所有UI介面設定都在 //fxml檔裡
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
------------------------
SMSevent class :
package JavaFXAppTest;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.*;
import javafx.scene.layout.*;
public class SMSevent extends AnchorPane{
@FXML
TextField user,pass,phone;
TextArea content;
Button send,clear;
Label result;
public void sendMessage(ActionEvent event) {
SMS SMStest = new SMS();
SMStest.setmessage(user.getText(),pass.getText(),phone.getText(),content.getText());
System.out.println(SMStest.go());
}
public void clearAll(ActionEvent event) {
user.setText(null);
pass.setText(null);
phone.setText(null);
content.setText(null);
}
}

[解决办法]
应该是没有参数引起的
看下
改为
public static void main(String[] args) {
launch(new String[]{"a","b"});
}
