Java控制鼠標和鍵盤的方法

1、Java 控制鼠標和鍵盤的方法ava SDK 1.3 以后實現(xiàn)了Robot 類。此類用于為測試自動化、自運行演示程序和其他需要控制鼠標和鍵盤的應用程序生成本機系統(tǒng)輸入事件。Robot 的主要目的是便于Java 平臺實現(xiàn)自動測試。使用該類生成輸入事件與將事件發(fā)送到AWT事件隊列或AWT組件的區(qū)別在于：事件是在平臺的本機輸入隊列中生成的。例如， Robot.mouseMove 將實際移動鼠標光標，而不是只生成鼠標移動事件。Robot 中主要的鼠標和鍵盤控制方法有：void keyPress(int keycode) 按下給定的鍵。 ? void keyRelease(int keycode) 釋放

2、給定的鍵。void mouseMove(int x, int y) 將鼠標指針移動到給定屏幕坐標。 ? void mousePress(int buttons) 按下一個或多個鼠標按鈕。 ? void mouseRelease(int buttons) 釋放一個或多個鼠標按鈕。 ?void mouseWheel(int wheelAmt)在配有滾輪的鼠標上旋轉滾輪。下面就讓我們來實戰(zhàn)鼠標控制，實現(xiàn)一個簡單的鼠標控制程序MouseController 。程序功能很簡單：隨機移動鼠標并點擊左鍵。代碼如下：import java.awt.AWTException; import java.awt.D

3、imension; import java.awt.Robot; import java.awt.Toolkit;import java.awt.event.InputEvent; import java.util.Random; /* */* author sxc 石新春 * Create date 2007-11-6 */ public class MouseController implements Runnable privateDimension dim; private Random rand; private Robot robot; private volatile boole

4、an stop = false; public MouseController() dim = Toolkit.getDefaultToolkit().getScreenSize(); rand =new Random();try robot = new Robot(); catch (AWTException ex)ex.printStackTrace();public void run() while(!stop) int x = rand.nextInt(dim.width);int y =rand.nextInt(dim.height);robot.mouseMove(x, y);ro

5、bot.mousePress(InputEvent.BUTTON1_MASK);try Thread.sleep(2000); catch (InterruptedException ex)ex.printStackTrace(); public synchronized void stop() stop = true;public static void main(String args) MouseController mc = new MouseController();ThreadmcThread = new Thread(mc);System.out.println("Mo

6、use Controller start");mcThread.start();try Thread.sleep(60000); catch (InterruptedException ex)ex.printStackTrace();mc.stop();System.out.println("Mouse Controller stoped"); 當然鍵盤映射也類似，無非是使用void keyPress(int keycode) ?，F(xiàn) 在實現(xiàn)了控制鼠標和鍵盤，接下了我們要獲取操作后的效果（屏幕截圖） 。好在 Robot 類也提供了一個方法：BufferedImage

7、createScreenCapture(Rectangle screenRect)；可以直接將全屏幕或某個屏幕區(qū)域的像素拷貝到一個BufferedImage 對象中。好，下面實戰(zhàn)使用robot 截屏，實現(xiàn) Capture 程序，每隔5 秒截屏一次。rand = new Random();try robot = new Robot(); catch (AWTException ex)ex.printStackTrace();public void run() while(!stop) int x = rand.nextInt(dim.width);int y =rand.nextInt(dim.

8、height);robot.mouseMove(x, y);robot.mousePress(InputEvent.BUTTON1_MASK);try Thread.sleep(2000); catch (InterruptedException ex)ex.printStackTrace(); public synchronized void stop() stop = true;public static void main(String args) MouseController mc = new MouseController();mcThread = new Thread(mc);S

9、ystem.out.println("Mouse Controller start");mcThread.start();try Thread.sleep(60000); catch (InterruptedException ex)ex.printStackTrace();mc.stop();System.out.println("Mouse Controller stoped");當然鍵盤映射也類似，無非是使用void keyPress(intThreadkeycode)?，F(xiàn) 在實現(xiàn)了控制鼠標和鍵盤，接下了我們要獲取操作后的效果（屏幕截圖） 。好在

10、Robot 類也提供了一個方法： BufferedImagecreateScreenCapture(Rectangle screenRect)；可以直接將全屏幕或某個屏幕區(qū)域的像素拷貝到一個好，下面實戰(zhàn)使用robot 截屏，實現(xiàn)BufferedImage 對象中。Capture 程序，每隔5 秒截屏一次。代碼如下：import java.awt.AWTException; import java.awt.Canvas; import java.awt.Dimension; import java.awt.EventQueue; import java.awt.Graphics; import

11、java.awt.Rectangle; import java.awt.Robot; import java.awt.Toolkit;import java.awt.image.BufferedImage; importjavax.swing.GroupLayout; import javax.swing.JFrame;import javax.swing.WindowConstants;import javax.swing.GroupLayout.Alignment; /* */* author sxc 石新春 *Create date 2007-11-6 */ public class C

12、apture extends JFrame implements Runnable private Canvas screenCanvas;private volatile boolean stop;private Robot robot;private Dimension dim;public Capture()initComponents();try robot = new Robot(); catch (AWTException ex)ex.printStackTrace();dim = Toolkit.getDefaultToolkit().getScreenSize(); priva

13、te void initComponents() screenCanvas = new java.awt.Canvas();setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);stop = true;setResizable(false);GroupLayout layout = new GroupLayout(getContentPane();getContentPane().setLayout(layout);layout.setHorizontalGroup(layout.createParallelGroup(Alignmen

14、t.LEADING).addCompon ent(screenCanvas,GroupLayout.PREFERRED_SIZE, 519,GroupLayout.PREFERRED_SIZE) ); layout.setVerticalGroup(layout.createParallelGroup(Alignment. LEADING).addComponent(screenCanvas,GroupLayout.PREFERRED_SIZE, 434,GroupLayout.PREFERRED_SIZE) ); pack(); public static void main(String

15、args) final Capturecapture = new Capture();EventQueue.invokeLater(newRunnable() public void run() capture.setVisible(true););cutThread.start(); public void run() stop = false;while(!stop) BufferedImage bImage = robot.createScreenCapture(newRectangle(dim.width, dim.height);Graphics g = this.screenCan

16、vas.getGraphics();g.drawImage(bImage, 0, 0, this);try Thread.sleep(5000); catch (InterruptedException ex)ex.printStackTrace();private synchronized void stop() stop = true;例子二：import java.awt.AWTException; import java.awt.Robot; import java.awt.event.KeyEvent; import java.io.IOException;public class RobotExp public static void main(String args) try tryRuntime.get
