用Java截屏（机器人，代码可以工作，但不能与外部全屏应用程序一起使用）

用Java截屏（机器人，代码可以工作，但不能与外部全屏应用程序一起使用）

这个问题已知吗？

是。通常，这是由于将渲染降低到图形卡本身的级别所引起的（很大程度上是在 *** 作系统方面造成的）。

..以及如何解决这个问题？

AFAIU无法修复。甚至本机截图应用程序。将无法获得此类渲染的屏幕截图。

为了解决此问题，可以模拟一些“打印屏幕”键吗？

import java.awt.Robot;import java.awt.Toolkit;import java.awt.datatransfer.Clipboard;import java.awt.datatransfer.DataFlavor;import java.awt.event.KeyEvent;public class ScreenshotUsingPrintScreen {    public static void main(String[] args) throws Exception {        int i = KeyEvent.VK_PRINTSCREEN;        Clipboard cb = Toolkit.getDefaultToolkit().getSystemClipboard();        DataFlavor[] flavors = cb.getAvailableDataFlavors();        System.out.println("Before: ");        for (DataFlavor flavor : flavors) { System.out.println(flavor);        }        // get the screenshot        Robot robot = new Robot();        robot.keyPress(KeyEvent.VK_PRINTSCREEN);        robot.delay(40);        robot.keyRelease(KeyEvent.VK_PRINTSCREEN);        robot.delay(40);        cb = Toolkit.getDefaultToolkit().getSystemClipboard();        flavors = cb.getAvailableDataFlavors();        System.out.println("After: ");        for (DataFlavor flavor : flavors) { System.out.println(flavor);        }    }}
