我想知道如何基于 X、Y 鼠标坐标在 android 上执行拖动?考虑两个简单的例子,Team Viewer/QuickSupport 分别在远程智能手机上绘制“密码模式”和 Windows Paint 的 Pen。

我所能做的就是模拟触摸(with dispatchGesture()and also AccessibilityNodeInfo.ACTION_CLICK)。

我找到了这些相关链接,但不知道它们是否有用:

下面是我的工作代码,用于将鼠标坐标(PictureBox控制内部)发送到远程电话并模拟触摸。

Windows 窗体应用程序:

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
    foreach (ListViewItem item in lvConnections.SelectedItems)
    {
        // Remote screen resolution
        string[] tokens = item.SubItems[5].Text.Split('x'); // Ex: 1080x1920

        int xClick = (e.X * int.Parse(tokens[0].ToString())) / (pictureBox1.Size.Width);
        int yClick = (e.Y * int.Parse(tokens[1].ToString())) / (pictureBox1.Size.Height);

        Client client = (Client)item.Tag;

        if (e.Button == MouseButtons.Left)
            client.sock.Send(Encoding.UTF8.GetBytes("TOUCH" + xClick + "<|>" + yClick + Environment.NewLine));
    }
}

编辑:

我最后一次尝试是使用鼠标坐标(C# Windows 窗体应用程序)和自定义 android 例程(参考上面链接的“滑动屏幕”代码)的“滑动屏幕”,分别:

private Point mdownPoint = new Point();

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
    foreach (ListViewItem item in lvConnections.SelectedItems)
    {
        // Remote screen resolution
        string[] tokens = item.SubItems[5].Text.Split('x'); // Ex: 1080x1920

        Client client = (Client)item.Tag;

        if (e.Button == MouseButtons.Left)
        {
            xClick = (e.X * int.Parse(tokens[0].ToString())) / (pictureBox1.Size.Width); 
            yClick = (e.Y * int.Parse(tokens[1].ToString())) / (pictureBox1.Size.Height);

            // Saving start position:

            mdownPoint.X = xClick; 
            mdownPoint.Y = yClick; 

            client.sock.Send(Encoding.UTF8.GetBytes("TOUCH" + xClick + "<|>" + yClick + Environment.NewLine));
        }
    }
}

private void PictureBox1_MouseMove(object sender, MouseEventArgs e)
{
    foreach (ListViewItem item in lvConnections.SelectedItems)
    {
        // Remote screen resolution
        string[] tokens = item.SubItems[5].Text.Split('x'); // Ex: 1080x1920

        Client client = (Client)item.Tag;

        if (e.Button == MouseButtons.Left)
        {
            xClick = (e.X * int.Parse(tokens[0].ToString())) / (pictureBox1.Size.Width);
            yClick = (e.Y * int.Parse(tokens[1].ToString())) / (pictureBox1.Size.Height);

            client.sock.Send(Encoding.UTF8.GetBytes("MOUSESWIPESCREEN" + mdownPoint.X + "<|>" + mdownPoint.Y + "<|>" + xClick + "<|>" + yClick + Environment.NewLine));
        }
    }
}

安卓无障碍服务

public void Swipe(int x1, int y1, int x2, int y2, int time) {

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
    System.out.println(" ======= Swipe =======");

    GestureDescription.Builder gestureBuilder = new GestureDescription.Builder();
    Path path = new Path();
    path.moveTo(x1, y1);
    path.lineTo(x2, y2);

    gestureBuilder.addStroke(new GestureDescription.StrokeDescription(path, 100, time));
    dispatchGesture(gestureBuilder.build(), new GestureResultCallback() {
        @Override
        public void onCompleted(GestureDescription gestureDescription) {
            System.out.println("SWIPE Gesture Completed :D");
            super.onCompleted(gestureDescription);
        }
    }, null);
}

}

这会产生以下结果(但仍然不能像 TeamViewer 那样绘制“模式密码”)。但就像下面评论中所说的那样,我认为通过类似的方法,这可能可以使用持续手势来实现。欢迎在这个方向提出任何建议。

编辑2:

当然,解决方案是像以前的Edit中所说的那样继续手势

下面是我在这里找到的假定固定代码=>

安卓无障碍服务:

// Simulates an L-shaped drag path: 200 pixels right, then 200 pixels down.
Path path = new Path();
path.moveTo(200,200);
path.lineTo(400,200);

final GestureDescription.StrokeDescription sd = new GestureDescription.StrokeDescription(path, 0, 500, true);

// The starting point of the second path must match
// the ending point of the first path.
Path path2 = new Path();
path2.moveTo(400,200);
path2.lineTo(400,400);

final GestureDescription.StrokeDescription sd2 = sd.continueStroke(path2, 0, 500, false); // 0.5 second

HongBaoService.mService.dispatchGesture(new GestureDescription.Builder().addStroke(sd).build(), new AccessibilityService.GestureResultCallback(){

@Override
public void onCompleted(GestureDescription gestureDescription){
super.onCompleted(gestureDescription);
HongBaoService.mService.dispatchGesture(new GestureDescription.Builder().addStroke(sd2).build(),null,null);
}

@Override
public void onCancelled(GestureDescription gestureDescription){
super.onCancelled(gestureDescription);
}
},null);

然后,我的疑问是:如何正确发送上述代码的鼠标坐标,以及可以向任何方向拖动的方式?有什么想法?


编辑3:

我发现了两个用于执行拖动的例程,但它们使用的是UiAutomation + injectInputEvent()。AFAIK,事件注入仅适用于此处此处所述的系统应用程序,我不想要它。

这是找到的例程:

然后为了实现我的目标,我认为第二个例程更适合使用(遵循逻辑,不包括事件注入)与编辑 2pictureBox1_MouseDown上显示的代码并分别发送和pictureBox1_MouseMove(C# Windows 窗体应用程序)的所有点以Point[]动态填充和pictureBox1_MouseUp发送cmd 执行例程并使用这个数组填充。如果您对第一个例程有想法,请告诉我:D。

如果在阅读此编辑后您有可能的解决方案,请在答案中告诉我,同时我将尝试测试这个想法。

对不起,兄弟,但下面的代码就像我的英语一样糟糕:

public void mouseDraw(Point[] segments, int time) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {

        Path path = new Path();
        path.moveTo(segments[0].x, segments[0].y);

        for (int i = 1; i < segments.length; i++) {

            path.lineTo(segments[i].x, segments[i].y);

            GestureDescription.StrokeDescription sd = new GestureDescription.StrokeDescription(path, 0, time);

            dispatchGesture(new GestureDescription.Builder().addStroke(sd).build(), new AccessibilityService.GestureResultCallback() {

                @Override
                public void onCompleted(GestureDescription gestureDescription) {
                    super.onCompleted(gestureDescription);
                }

                @Override
                public void onCancelled(GestureDescription gestureDescription) {
                    super.onCancelled(gestureDescription);
                }
            }, null);
        }
    }
}

这里程序调用 dispatchGesturesegments.length-1时间,但只有最后一个手势会完成,因为每个手势都被 next 取消。来自官方文档:当前正在进行的任何手势,无论是来自用户、此服务还是其他服务,都将被取消。

正确的:

public void mouseDraw(Point[] segments, int time) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        Path path = new Path();
        path.moveTo(segments[0].x, segments[0].y);
        for (int i = 1; i < segments.length; i++) {
            path.lineTo(segments[i].x, segments[i].y);
        }
        GestureDescription.StrokeDescription sd = new GestureDescription.StrokeDescription(path, 0, time);
        dispatchGesture(new GestureDescription.Builder().addStroke(sd).build(), new AccessibilityService.GestureResultCallback() {
            @Override
            public void onCompleted(GestureDescription gestureDescription) {
                super.onCompleted(gestureDescription);
            }
            @Override
            public void onCancelled(GestureDescription gestureDescription) {
                super.onCancelled(gestureDescription);
            }
        }, null);
    }
}

这里我们Path先构建,然后使用dispatchGesture一次。

如果您需要等待每个分派的手势,然后使用Semaphore,例如,像这样(Kotlin):

    val sem = Semaphore(0, true)
    for (i in 1 until segments.size) {
        path.lineTo(segments.get(i).x.toFloat(), segments.get(i).y.toFloat())
        val sd = GestureDescription.StrokeDescription(path, 0, 1500)
        dispatchGesture(
                GestureDescription.Builder().addStroke(sd).build(),
                object : GestureResultCallback() {
                    override fun onCancelled(gestureDescription: GestureDescription?) {
                        super.onCancelled(gestureDescription)
                        sem.release()
                    }
                    override fun onCompleted(gestureDescription: GestureDescription?) {
                        super.onCompleted(gestureDescription)
                        sem.release()
                    }
                },
                null
        )
        sem.acquire()
    }

您是否尝试过使用AutoIt脚本?

您可以在特定窗口/屏幕中保存坐标。您可以在绘制图案时按住鼠标单击。

如果你想要的话,我也有一些示例代码/脚本给你!


编辑:

根据本教程,您可以在 C# 上使用 Auto-IT。

按着这些次序:

  1. 安装 Auto-IT
  2. 在参考管理器 (AutoItX3.dll) 中添加 Auto-IT 作为参考
  3. 然后导入您添加的库:Using AutoItX3Lib;
  4. 制作名为“auto”的新 AutoItX3 对象:AutoItX3 auto = new AutoItX3();
  5. 您现在可以执行 Auto It 命令。

这是执行鼠标单击的完整示例:

Using AutoItX3Lib;
AutoItX3 auto = new AutoItX3();
auto.MouseClick("left", 78, 1133, 1, 35)


使用AutoIt Window Info Tool可以检查要使用的坐标。

请注意鼠标坐标模式之间存在差异:

例如:auto.AutoItSetOption("MouseCoordMode", 1)将使用绝对屏幕坐标。在此处查看源代码。


对于按住鼠标单击,您可以检查MouseDown 功能
