C#中Scrcpy的剪贴板同步技巧有哪些

在C#中使用Scrcpy（一款用于在PC端控制安卓设备的工具）实现剪贴板同步需要以下步骤：

1. 使用Scrcpy库连接到安卓设备。
2. 在PC端监听剪贴板变化。
3. 将PC端剪贴板内容传输到安卓设备。
4. 在安卓设备上接收PC端的剪贴板内容并更新设备上的剪贴板内容。

以下是实现剪贴板同步的C#代码示例：

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Threading;

public class ClipboardSync
{
    [DllImport("user32.dll", SetLastError = true)]
    static extern IntPtr SetClipboardData(uint uFormat, IntPtr data);

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool OpenClipboard(IntPtr hWndNewOwner);

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool CloseClipboard();

    [DllImport("user32.dll")]
    static extern IntPtr GetClipboardData(uint uFormat);

    [DllImport("user32.dll")]
    static extern uint RegisterClipboardFormat(string lpszFormat);

    [DllImport("user32.dll", EntryPoint = "SendMessage", SetLastError = true)]
    static extern IntPtr SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);

    private const int WM_CLIPBOARDUPDATE = 0x031D;
    private const uint CF_UNICODETEXT = 13;

    private static string clipboardData;

    public static void Main()
    {
        IntPtr hwnd = Process.GetCurrentProcess().MainWindowHandle;
        AddClipboardFormatListener(hwnd);

        while (true)
        {
            Thread.Sleep(1000);
            // Check if clipboard data has changed
            string currentClipboardData = GetClipboardData();
            if (currentClipboardData != clipboardData)
            {
                clipboardData = currentClipboardData;
                // Sync clipboard data to Android device using Scrcpy
                SyncClipboardToAndroid(clipboardData);
            }
        }
    }

    private static string GetClipboardData()
    {
        if (!OpenClipboard(IntPtr.Zero))
        {
            return null;
        }

        IntPtr clipboardDataPtr = GetClipboardData(CF_UNICODETEXT);
        if (clipboardDataPtr == IntPtr.Zero)
        {
            CloseClipboard();
            return null;
        }

        string clipboardData = Marshal.PtrToStringUni(clipboardDataPtr);
        CloseClipboard();
        return clipboardData;
    }

    private static void SyncClipboardToAndroid(string data)
    {
        // Implement syncing clipboard data to Android device using Scrcpy
        // Example: ADB shell command to set clipboard data on Android device
        string adbCommand = $"adb shell input text \"{data}\"";
        Process.Start(new ProcessStartInfo
        {
            FileName = "cmd",
            Arguments = $"/c {adbCommand}",
            CreateNoWindow = true,
            UseShellExecute = false
        });
    }

    private static void AddClipboardFormatListener(IntPtr hwnd)
    {
        ChangeWindowMessageFilter(WM_CLIPBOARDUPDATE, 1);
        SendMessage(hwnd, WM_CLIPBOARDUPDATE, IntPtr.Zero, IntPtr.Zero);
    }

    [DllImport("user32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool ChangeWindowMessageFilter(uint message, uint dwFlag);
}

这段代码演示了如何在C#中监听PC端剪贴板的变化并将其同步到Android设备上。需要注意的是，要将剪贴板内容同步到Android设备，可以使用类似于ADB命令等方式。
