话不都说，直接上代码，复制粘贴到你的项目中

1、VirtualKeyboard.cs

[code]using UnityEngine;
using System;
using System.Collections;
using System.Diagnostics;
using System.Runtime.InteropServices;

public class VirtualKeyboard
{
[DllImport("user32")]
static extern IntPtr FindWindow(String sClassName, String sAppName);
[DllImport("user32")]
static extern bool PostMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);
private static Process _onScreenKeyboardProcess = null;
/// <summary>
/// Show the touch keyboard (tabtip.exe).
/// </summary>
public void ShowTouchKeyboard()
{
ExternalCall("C:\\Program Files\\Common Files\\Microsoft Shared\\ink\\tabtip.exe", null, false);
//ExternalCall("TABTIP", null, false);
}
/// <summary>
/// Hide the touch keyboard (tabtip.exe).
/// </summary>
public void HideTouchKeyboard()
{
uint WM_SYSCOMMAND = 274;
int SC_CLOSE = 61536;
IntPtr ptr = FindWindow("IPTip_Main_Window", null);
PostMessage(ptr, WM_SYSCOMMAND, SC_CLOSE, 0);
}
/// <summary>
/// Show the on screen keyboard (osk.exe).
/// </summary>
public void ShowOnScreenKeyboard()
{
//ExternalCall("C:\\Windows\\system32\\osk.exe", null, false);
if (_onScreenKeyboardProcess == null || _onScreenKeyboardProcess.HasExited)
_onScreenKeyboardProcess = ExternalCall("OSK", null, false);
}
/// <summary>
/// Hide the on screen keyboard (osk.exe).
/// </summary>
public void HideOnScreenKeyboard()
{
if (_onScreenKeyboardProcess != null && !_onScreenKeyboardProcess.HasExited)
_onScreenKeyboardProcess.Kill();
}
/// <summary>
/// Set size and location of the OSK.exe keyboard, via registry changes. Messy, but only known method.
/// </summary>
/// <param name='rect'>
/// Rect.
/// </param>
public void RepositionOnScreenKeyboard(Rect rect)
{
ExternalCall("REG", @"ADD HKCU\Software\Microsoft\Osk /v WindowLeft /t REG_DWORD /d " + (int)rect.x + " /f", true);
ExternalCall("REG", @"ADD HKCU\Software\Microsoft\Osk /v WindowTop /t REG_DWORD /d " + (int)rect.y + " /f", true);
ExternalCall("REG", @"ADD HKCU\Software\Microsoft\Osk /v WindowWidth /t REG_DWORD /d " + (int)rect.width + " /f", true);
ExternalCall("REG", @"ADD HKCU\Software\Microsoft\Osk /v WindowHeight /t REG_DWORD /d " + (int)rect.height + " /f", true);
}
private static Process ExternalCall(string filename, string arguments, bool hideWindow)
{
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = filename;
startInfo.Arguments = arguments;
// if just command, we don't want to see the console displayed
if (hideWindow)
{
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;
}
Process process = new Process();
process.StartInfo = startInfo;
process.Start();
return process;
}
}

2、OpenVirtualKeyboard.cs

[code]public class OpenVirtualKeyboard
{
static VirtualKeyboard vk = new VirtualKeyboard();

//打开键盘
public static void OpenKeyBoard()
{
vk.ShowTouchKeyboard();
}

//关闭键盘
public static void CloseKeyBoard()
{
vk.HideTouchKeyboard();
}

}

3、完成功能：使用InputFiled，点击焦点时弹出，失去焦点时关闭

     你需要将下面脚本挂到InputField上

   InputFiledSelect .cs

[code]using UnityEngine;
using UnityEngine.EventSystems;

public class InputFiledSelect :  MonoBehaviour,ISelectHandler,IDeselectHandler
{
public void OnDeselect(BaseEventData eventData)
{
OpenVirtualKeyboard.CloseKeyBoard();
}

public void OnSelect(BaseEventData eventData)
{
OpenVirtualKeyboard.OpenKeyBoard();
}
}
