实现效果

背景

对于日常刷课每十分钟点击“继续学习”的行为，或者说是单机游戏里某项重复的行为想使其实现“自动化”。我们可以通过JavaFx里的Robot类来实现。

难点

窗口穿透
鼠标行为的记录

搭建程序

需要掌握的知识

窗口测试

@Override
public void start(Stage stage) throws Exception {
    Scene scene = new Scene(new Pane (), 320, 240);
    stage.setTitle("按键精灵!");
    stage.setScene(scene);
    stage.show();
}

获取鼠标位置

Robot robot = new Robot ();
//获得鼠标位置
Point2D mp = robot.getMousePosition ();
System.out.println (mp);

模拟鼠标单击

左

MouseButton.PRIMARY

右

MouseButton.SECONDARY

滚轮子

MouseButton.MIDDLE

模拟鼠标移动

//鼠标移动
robot.mouseMove (new Point2D (800,800));

鼠标行为监听

//监听鼠标单击
pane.setOnMouseClicked (e->{          
     System.out.println (e.getButton ());
     System.out.println (e.getSceneX ());
     System.out.println (e.getSceneY ());
});
//监听鼠标键入
pane.setOnMousePressed (e->{});
//监听鼠标释放
pane.setOnMouseReleased (e->{});
//监听鼠标在摁着某个键时的拖动
pane.setOnMouseDragged (e->{});

完整源码及详细解释

public class QMApp extends Application {
    @Override
    public void start(Stage stage) throws Exception {
        /**
         * 内部类，将每次鼠标的行为以及坐标记录下来
         */
        class MyMouseEvent{
            //鼠标行为
            MouseButton mb;
            //类型
            EventType et;
            //坐标
            Point2D point2D;
            public MyMouseEvent(MouseButton mb, EventType et, Point2D point2D) {
                this.mb = mb;
                this.et=et;
                this.point2D = point2D;
            }
        }
        //创建面板
        VBox pane = new VBox ();
        //对齐方式
        pane.setAlignment (Pos.TOP_LEFT);
        //robot关键对象
        Robot robot = new Robot ();
        //记录鼠标行为
        LinkedList<MyMouseEvent> list = new LinkedList<> ();
        //开始
        Button beginb = new Button ("开始");
        beginb.setTextFill (Color.RED);
        //结束
        Button endb = new Button ("结束");
        endb.setTextFill (Color.RED);
        pane.getChildren ().addAll (beginb,endb);
        //点击“开始”按钮时，鼠标行为储存进列表
        beginb.setOnMouseClicked (m->{
            pane.setOnMouseDragged (e->{
                list.add (new MyMouseEvent (e.getButton (),e.getEventType (),new Point2D (e.getSceneX (),e.getSceneY ())));
            });
            pane.setOnMousePressed (e->{
                list.add (new MyMouseEvent (e.getButton (),e.getEventType (),new Point2D (e.getSceneX (),e.getSceneY ())));
            });
            pane.setOnMouseReleased (e->{
                list.add (new MyMouseEvent (e.getButton (),e.getEventType (),new Point2D (e.getSceneX (),e.getSceneY ())));
            });
        });
        //点击“结束”按钮时，鼠标行为储存进列表
        endb.setOnMouseClicked (e->{
            pane.getChildren ().remove (beginb);
            for (int i = 0; i < list.size (); i++) {

                //每次鼠标模拟都将窗口透明，实现穿透
                stage.setOpacity (0);
                if (list.get (i).et== MOUSE_DRAGGED){
                    robot.mousePress (list.get (i).mb);
                }else {
                    robot.mouseMove (list.get (i).point2D);
                    robot.mouseClick (list.get (i).mb);
                }
                try {
                    //为了效果明显，进行延迟
                    Thread.sleep (50);
                } catch (InterruptedException ex) {
                    ex.printStackTrace ();
                }
            }
        });
        //面板不参与计算边界。鼠标点击事件发生后，会计算应该是哪个组件位于鼠标所在点的位置，而该面板因为不参与边界计算，所以也不会捕获到鼠标事件
        pane.setPickOnBounds(false);
        //窗口在前，不能拖到，都没有
        stage.initStyle (StageStyle.UNDECORATED);
        //窗口最大化
        stage.setMaximized (true);
        //窗口透明度，为了使得开始按钮不会消失同时可以看见其他窗口，半透明
        stage.setOpacity (0.3);
        Scene scene = new Scene(pane);
        stage.setTitle("按键精灵");
        stage.setScene(scene);
        stage.show();
    }
