Xamarin.UITest: How To Retrieve Coordinates of Device Display

Question

I am writing a UITest in C# using Xamarin.UITest.

How can I retrieve the coordinates of the device's screen dynamically in the UITest?

Answer 1

In Xamarin.UITest, when you call app.Query(), the first query result will return the device display. You can then grab the XY coordinates using the Rect property.

Below is a sample REPL output showing the result of app.Query().First(), and sample code assigning the XY coordinates to variables in your UITest.

Sample Output from REPL

Sample Code

var windowQuery = app.Query().First();

var topLeftXCoordinate = windowQuery.Rect.X;
var topLeftYCoordinate = windowQuery.Rect.Y;

var topRightXCoordinate = windowQuery.Rect.X + windowQuery.Rect.Width;
var topRightYCoordinate = windowQuery.Rect.Y;

var bottomLeftXCoordinate = windowQuery.Rect.X;
var bottomLeftYCoordinate = windowQuery.Rect.Y + windowQuery.Rect.Height;

var bottomRightXCoordinate = windowQuery.Rect.X + windowQuery.Rect.Width;
var bottomRightYCoordinate = windowQuery.Rect.Y + windowQuery.Rect.Height;

var centerXCoordinate = windowQuery.Rect.CenterX;
var centerYCoordinate = windowQuery.Rect.CenterY;
