我正在開發某種時間跟蹤器,我需要計算在特定時間段內使用了多少次鼠標或鍵盤。我不是指點擊界面,而是點擊和關鍵事件的共同點。我怎麼攔截它?javafx 8 - 按下的點擊次數和按鍵次數

謝謝,但我不知道它會適用於桌面的任何角落。例如,我最小化了我的應用,它仍然會記錄點擊次數。我猜這不行,但我會嘗試,謝謝 – avalon

我終於找到了一個解決方案:

首先,我們需要創建一個監聽類

import org.jnativehook.mouse.NativeMouseEvent; 
import org.jnativehook.mouse.NativeMouseInputListener; 

public class NativeMouseListener implements NativeMouseInputListener { 
    public void nativeMouseClicked(NativeMouseEvent e) { 
     System.out.println("Mosue Clicked: " + e.getClickCount()); 
    } 

    public void nativeMousePressed(NativeMouseEvent e) { 
     //System.out.println("Mosue Pressed: " + e.getButton()); 
    } 

    public void nativeMouseReleased(NativeMouseEvent e) { 
     //System.out.println("Mosue Released: " + e.getButton()); 
    } 

    public void nativeMouseMoved(NativeMouseEvent e) { 
     //System.out.println("Mosue Moved: " + e.getX() + ", " + e.getY()); 
    } 

    public void nativeMouseDragged(NativeMouseEvent e) { 
     //System.out.println("Mosue Dragged: " + e.getX() + ", " + e.getY()); 
    } 
} 

然後,做在你的代碼如下:

try { 
    GlobalScreen.registerNativeHook(); 
} 
catch (NativeHookException ex) { 
    System.err.println("There was a problem registering the native hook."); 
    System.err.println(ex.getMessage()); 
    System.exit(1); 
} 

GlobalScreen.addNativeMouseListener(new NativeMouseListener()); 

您可以從jnative罐子有:

但我不確定它是否適用於Mac。稍後再試。希望有幫助
