如何使用Java打开和关闭虚拟键盘

我尝试了这里的所有答案：

在Java程序中打开Windows虚拟键盘 https://stackoverflow.com/questions/4948420/open-the-windows-virtual-keyboard-in-a-java-program

我执行了Runtime.getRuntime().exec("cmd /c osk");我无法按照建议关闭它，我需要在一些过程后关闭它。

I tried:

import java.io.IOException;

public class ShowVirtualKeyboard{

    public static void main(String argv[]) throws IOException {
    String sysroot = System.getenv("SystemRoot");
    Process proc = Runtime.getRuntime().exec(sysroot + "/system32/osk.exe");
}
}

我得到了错误

Cannot run program "C://Windows/system32/osk.exe": CreateProcess error=740, The requested operation requires elevation

我认为有点晚了，但我设法像您一样使用 cmd 和 JNA（Java Native Access）库打开和关闭虚拟键盘（TabTip.exe）：

要打开键盘：

// Java

String command = "cmd /c \"C:\\Program Files\\Common Files\\Microsoft Shared\\ink\\TabTip.exe\"";
Process = Runtime.getRuntime().exec(command);
process.waitFor();
process.destroy();

// Kotlin

val command = "cmd /c \"C:\\Program Files\\Common Files\\Microsoft Shared\\ink\\TabTip.exe\""
val process = Runtime.getRuntime().exec(command)
process.waitFor()
process.destroy()

关闭它：

//Java

String KEYBOARD_CLASS_NAME = "IPTIP_Main_Window";
int WM_SYS_COMMAND = 0x0112;
WinDef.WPARAM SC_CLOSE = WinDef.WPARAM(0xF060);
WinDef.HWND handle = User32.INSTANCE.FindWindow(KEYBOARD_CLASS_NAME, "");
if (handle != null) {
    User32.INSTANCE.SendMessage(handle, WM_SYS_COMMAND, SC_CLOSE, WinDef.LPARAM(0));
}

//Kotlin

val KEYBOARD_CLASS_NAME = "IPTIP_Main_Window"
val WM_SYS_COMMAND = 0x0112
val SC_CLOSE = WinDef.WPARAM(0xF060)
val handle = User32.INSTANCE.FindWindow(KEYBOARD_CLASS_NAME, "")
if (handle != null) {
    User32.INSTANCE.SendMessage(handle, WM_SYS_COMMAND, SC_CLOSE, WinDef.LPARAM(0))
}

关闭进程或从 cmd 杀死它对我来说不起作用，所以我必须以本机方式执行此操作。我希望这也适合你。
