How to reach the end of a scroll bar in appium?

问题

I'm trying to automate scrolling of a horizontal bar,where the elements of the bar are dynamic and are getting fetched from an API.

Is there a way to automate it in appium?

回答1:

If you have any element or text in the bottom of page then you can use UiAutomator2.

add in desired capability 'UiAutomator2' if you are using appium.

capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, "UiAutomator2");

Now use below functions if you have element's id

 public void scrollByID(String Id, int index) {

        try {

             driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().resourceId(\""+Id+"\").instance("+index+"));")); 

        } catch (Exception e) {
           e.printStackTrace();
        }
    }

Use this if you have element's text.

public void scrollByText(String menuText) {

        try {

             driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().textMatches(\"" + menuText + "\").instance(0));")); 
        } catch (Exception e) {
           e.printStackTrace();
        }
    }

If you don't know any element in botton then you have to use screen size

public void scrollToBottom() {

      int  x = driver.manage().window().getSize().width / 2;
      int start_y = (int) (driver.manage().window().getSize().height * 0.2);
      int end_y = (int) (driver.manage().window().getSize().height * 0.8);
        TouchAction dragNDrop = new TouchAction(driver)
                        .press(PointOption.point(x,start_y)).waitAction(WaitOptions.waitOptions(Duration.ofMillis(500)))
                        .moveTo(PointOption.point(x, end_y))
                        .release();
        dragNDrop.perform();
    }
