How can I get the element ID for performing swipe actions on an element

[Rajas]

Hi,
Iam currently testing an Android App using appium with python. A certain screen of the app contains a list of items and swiping each item gives a pop-up menu. Iam locating each item using "driver.find_element_tag_name('TextView')" but the gestures.md in docs folder says that element ID is needed to be passed:

* `POST session:/sessionId/touch/swipe` - perform a swipe/drag on the screen or an element
    * URL Parameter: sessionId of session to route to
    * JSON parameters:
        * `touchCount` (optional, default `1`): how many fingers to flick with
        * `startX` (optional, default `0.5`): x coordinate where swipe begins (in pixels or relative units)
        * `startY` (optional, default `0.5`): y coordinate where swipe begins (in pixels or relative units)
        * `endX` (required): x coordinate where swipe ends (in pixels or relative units)
        * `endY` (required): y coordinate where swipe ends (in pixels or relative units)
        * `duration` (optional, default `0.8`): time (in seconds) to spend performing the swipe/drag
        * `element` (optional): ID of element to scope this command to

How shall I get the element ID  of the TextView element

driver.find_element_tag_name('TextView').getID()

Given element el in python, id is el.id

I need some clarification about the "element" scope. My understanding from the documentation is that the swipe will only take place within the graphical dimensions of the specified element. What if I need to swipe beyond the boundaries of this element?

For example, say I have a graphical button that I need to slide upward 50 pixels to reveal a hidden menu. Do I need to know the absolute coordinates of the element to make it work? If so, how do I get the coordinates of a given element?

It's possible to calculate the relative position of an element. If you
use pixel values then that doesn't work when the screen changes.
Here's an example in Ruby.

Thanks for the tips. I used WebElement.getLocation() to grab the coordinates of the element, then swipe based on that.

I tend to think of swiping in terms of swiping a given element in a specified direction rather than specific coordinates on the screen, so I came up with this helper method in case it's useful for anyone else:

    /**

     * Swipes an element a specified offset distance

     * X/Y Coordinates: distance in number of pixels, values < 1 specify relative screen offset distance 

     * (example: .75 swipes 75 percent of the width of screen)

     * @param elementDef - By object defining the element

     * @param touchCount - amount of fingers in touch

     * @param xDistance - positive:right, negative:left 

     * @param yDistance - positive:up, negative:down, 

     * @param duration - amount of seconds to swipe for

     */

    public void swipeElement(WebElement element, double touchCount, double xDistance, double yDistance, double duration) {

   

    // get location of element

    Point coords = element.getLocation();

    double startX = coords.x;

    double startY = coords.y;

   

    // get window size

    Dimension size = driver.manage().window().getSize();

   

    //calculate end distance

    double endX;

    double endY;

   

    //if the distance is a decimal value < 1, it's a relative screen distance

    if (Math.abs(xDistance) < 1) {

    endX = startX + (size.width * Math.abs(xDistance));

    }

    else {

    endX = startX + xDistance;

    }

    if (Math.abs(yDistance) < 1) {

    endY = startY - (size.width * Math.abs(yDistance));

    }

    else {

    endY = startY - yDistance;

    }

   

    Point endCoords = new Point((int)endX, (int)endY);

   

    util.log("Swiping from: " + coords + " To: " + endCoords);

   

    //set up arguments to mobile: swipe

   HashMap<String, Double> flickObject = new HashMap<String, Double>();

   flickObject.put("touchCount", touchCount);

   flickObject.put("startX", startX);

   flickObject.put("startY", startY);

   flickObject.put("endX", endX);

   flickObject.put("endY", endY);

   flickObject.put("duration", duration);

   driver.executeScript("mobile: swipe", flickObject);

    }
