How perform a drag (based in X,Y mouse coordinates) on Android using AccessibilityService? [Still Without Solution]

问题

I want know how to perform a drag on android based in X, Y mouse coordinates? consider as two simple examples, the Team Viewer/QuickSupport drawing the "password pattern" on remote smartphone and the Pen of Windows Paint respectively.

All that i'm able of make is simulate touch (with dispatchGesture() and also AccessibilityNodeInfo.ACTION_CLICK).

I found these relevants links, but not know if they can be useful:

Perform swipe on screen using AccessibilityService
Example 1
Continued gestures

Below is my working code that is used to send mouse coordinates (inside of PictureBox control) to remote phone and simulate touch.

Windows Forms Application:

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));
    }
}

Edit:

My last attempt was a "swipe screen" using mouse coordinates (C# Windows Forms Application) and a custom android routine (with reference to code of "swipe screen" linked above), respectively:

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));
        }
    }
}

android AccessibilityService:

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);
}

}

that produces the following result (but still not is able to draw "pattern password" like TeamViewer for example). But like said on comment below, I think that with a similar approach this can be achieved using Continued gestures probably. Any suggestions in this direction will be welcome.

Edit 2:

Definitely, the solution is continued gestures like said on previous Edit.

Simulating joystick movement using AccessibilityService
Why the continueStroke function is not work

And below is a supposed fixed code that i found here =>

android AccessibilityService:

// 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);

Then, my doubt is: how send correctly mouse coordinates for code above, of the way that can perform drag to any direction? Some idea?

Edit 3:

I found two routines that are used to perform drag, but they are using UiAutomation + injectInputEvent(). AFAIK, injection of event works only in a system app like said here and here and i not want it.

This are routines found:

public boolean swipe(int downX, int downY, int upX, int upY, int steps, boolean drag)
public boolean swipe(Point[] segments, int segmentSteps)

Then to achieve my goal, i think that 2rd routine is more appropriated to use (following the logic, excluding event injection) with code showed on Edit 2 and send all points in pictureBox1_MouseDown and pictureBox1_MouseUp (C# Windows Forms Application) respectively to fill Point[] dynamically and on pictureBox1_MouseUp send cmd to execute the routine and use this array filled. If you have a idea to 1st routine, let me know :D.

If after read this Edit you have a possible solution, show me in a answer please, while i will try and test this idea.

回答1:

Have you tried to use AutoIt scripting?

You can save coordinates within specific windows/screens. You can hold mouseclick pressed while drawing the pattern.

I also have some example code / scripts for you if you want them!

EDIT:

According to this tutorial you can use Auto-IT on C#.

Follow these steps:

Install Auto-IT
Add Auto-IT as reference in reference manager (AutoItX3.dll)
Then import library that you added with: Using AutoItX3Lib;
Make new AutoItX3 object called 'auto': AutoItX3 auto = new AutoItX3();
You can now execute Auto It commands.

This is the complete example for executing a mouseclick:

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

With the AutoIt Window Info Tool you can check the coordinates you want to use.

Please note there are differences between mouse coordinates modes:

for example: auto.AutoItSetOption("MouseCoordMode", 1) will use absolute screen coordinates. See source here.

For holding the mouseclick down, you can check MouseDown Function
