Scroll Gesture

By using android uiautomator method we can perform the scroll operation. It uses UiScrollable and UiSelector object of android class to perform scroll operation.

Syntax : 

driver.find_element(AppiumBy.ANDROID_UIAUTOMATOR,'new UiScrollable(new UiSelector()).scrollIntoView(text("Locator_Value"))')

Example: In the below example we are launching the app on an Android device and clicking on the button using a text locator and then scroll and click on the button.

  • Launch the App on an Android device.
  • Click on the button using text locator
  • Scroll and click on the button
  • Wait for 2 seconds
  • Close the App

from appium import webdriver
from selenium.common.exceptions import ElementNotVisibleException, ElementNotSelectableException, NoSuchElementException
from selenium.webdriver.support.wait import WebDriverWait
from appium.webdriver.common.appiumby import AppiumBy
import time

# Step 1 : Create "Desired Capabilities"
desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['automationName'] = 'UiAutomator2'
desired_caps['platformVersion'] = '10'
desired_caps['deviceName'] = 'Pixel3XL'
desired_caps['app'] = ('/Skill2Lead/Appium_Demo_App/Android/Android_Appium_Demo.apk')
desired_caps['appPackage'] = 'com.skill2lead.appiumdemo'
desired_caps['appActivity'] = 'com.skill2lead.appiumdemo.MainActivity'

# Step 2 : Create "Driver object"
driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub", desired_caps)

# Step 3 : Create "WebDriver object"
wait = WebDriverWait(driver, 25, poll_frequency=1,
                     ignored_exceptions=[ElementNotVisibleException, ElementNotSelectableException,
                                         NoSuchElementException])

# Step 4 : Scroll and click on "Scroll View" button
ele = wait.until(lambda x: x.find_element(AppiumBy.ANDROID_UIAUTOMATOR,'text("ScrollView")'))
ele.click()

# Step 5 : Scroll and click on "Button15" button
btn = driver.find_element(AppiumBy.ANDROID_UIAUTOMATOR,'new UiScrollable(new UiSelector()).scrollIntoView(text("BUTTON15"))')
btn.click()

time.sleep(2)
driver.quit()

Now let us see by using explicit wait click on the button.

btn.click()

time.sleep(2)

driver.quit()
