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 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();
}
public static void main(String[] args) {
launch (args);
}
