How to scroll to specific element inLatest version of Appium using Java?

问题

My element is not visible on screen but when i use .isDisplayed() method i get true my code is as below

Point xy = send_mail.getCoordinates().onScreen();
        int a=xy.getX();
        int b =xy.getY();
        System.out.println("a" + xy.getX() + "b" + xy.getY());
        TouchAction touchAction = new TouchAction(driver);
        touchAction.moveTo(a, b);

send_mail is xpath of element to be found. This is tracelog help! I cannot use while loop to iterate until element is not displayed as it it considered visible y appium.

Try this :

Following is the method to get coordinates of perticular element:

public int[] getCoordinates(String xpath, AndroidDriver<AndroidElement> driver) throws Exception {
         //Locate element for which you wants to retrieve x y coordinates.
        //int arr[] ;
         int arr[] = new int[10];
         //Get the middle co-ordinates of the element and store in  the array.
         WebElement element = driver.findElementByXPath(xpath);
         int leftX = element.getLocation().getX();
         int rightX = leftX + element.getSize().getWidth();
         int middleX = (rightX + leftX) / 2;
         int upperY = element.getLocation().getY();
         int lowerY = upperY + element.getSize().getHeight();
         int middleY = (upperY + lowerY) / 2;
         System.out.println("x co-ordinat: "+middleX+"\n y co-ordinat: "+middleY+"\n left x axis: "+leftX+"\n right x: "+rightX);
         arr[0]= middleX;
         arr[1]= middleY;
         arr[2]= rightX;
         arr[3]= leftX;
         return arr;
         }

Then Use:

            int[] co_ordinates = takeaway.getCoordinates(Xpath of from Element  , driver);
            System.out.println(" x cordinate: " + co_ordinates[0] + "\n y cordinat: " + co_ordinates[1]);
            int[] dinates = takeaway.getCoordinates(Xpath of To Element, driver);
            TouchAction touch = new TouchAction(driver);
            touch.longPress(co_ordinates[0], co_ordinates[1]).moveTo(dinates[0], dinates[1]).release().perform();
