How to scroll the list view and read out all the list items in Android using Java

[Shiva Ghanate]

List<WebElement> mylist = driver.findElements(By.id("com.androidexample.listview:id/list"));

//How to scroll after this in Java.

 

I can't find anything like driver.scroll() method.

 

Also the list has more than 8 elements, so how do I get the list of all the elements in the whole list.

 

Once I get the length of the list I am aiming to run a for loop and check every item for the content in them.

Hi Shiva,

You can use following code. https://github.com/appium/appium/blob/master/docs/en/gestures.md

JavascriptExecutor js = (JavascriptExecutor) driver;
HashMap<String, String> scrollObject = new HashMap<String, String>();
scrollObject.put("direction", "down");
scrollObject.put("element", ((RemoteWebElement) element).getId());
js.executeScript("mobile: scroll", scrollObject);

I am new to Java coding.

I saw this code, but was not able to implement it for my list view,

 

JavascriptExecutor js = (JavascriptExecutor) driver;
HashMap<String, String> scrollObject = new HashMap<String, String>();
scrollObject.put("direction", "down");
scrollObject.put("element", ((RemoteWebElement) element).getId());

 

//when i try to give my mylist as the element, it doesnt work for me. 

js.executeScript("mobile: scroll", scrollObject);

 

Can you help me with that.??

It would be helpful if you can explain me how does the code snippet works.

Hi,

 

I have modified the code a little, but still not able to scroll.

 

WebElement mylist= driver.findElement(By.id("com.androidexample.listview:id/list"));
    

// Code for scrolling the lt

     JavascriptExecutor js = (JavascriptExecutor) driver;
     HashMap<String, String> scrollObject = new HashMap<String, String>();
     scrollObject.put("direction", "down");

     scrollObject.put("element", mylist.getText());

     js.executeScript("mobile: scroll", scrollObject);

 

Error what I get : org.openqa.selenium.WebDriverException: ERROR running Appium command: string is not a function

Hi I used this code, which works for scrolling the list, but then it throws an error.

WebElement mylist= driver.findElement(By.id("com.androidexample.listview:id/list"));

// Code for scrolling the list

JavascriptExecutor js = (JavascriptExecutor) driver;

HashMap<String, String> scrollObject = new HashMap<String, String>();

scrollObject.put("direction", "down");

scrollObject.put("element", ((RemoteWebElement) mylist).getId());

js.executeScript("mobile: scrollTo", scrollObject);

System.out.println("Scrolling worked");

Scrolls the screen and then it throws error:

This is an old thread, but hopefully this helps someone :) 

I ran into this same error, you just need to add in one more element to your HashMap, that is the text you want to scroll to.  This is my code that worked. 

MobileElement element = (MobileElement) DeviceWrapper.getAppiumDriver().findElementByClassName(locator);
JavascriptExecutor js = (JavascriptExecutor) DeviceWrapper.getAppiumDriver();

HashMap<String, String> scrollObject = new HashMap<String, String>();
scrollObject.put("direction", "down");
scrollObject.put("element", ((RemoteWebElement) element).getId());

scrollObject.put("text", text);
js.executeScript("mobile: scrollTo", scrollObject);

And here is the code from the Controller.js file that it's actually calling.  

exports.mobileScrollTo = function (req, res) {
  logCustomDeprecationWarning('mobile method', 'scrollTo',
      "scrollTo will be removed in a future version of appium");
  req.body = _.defaults(req.body, {
    element: null
  , text: null
  , direction: "vertical"
  });

  var element = req.body.element
    , text = req.body.text
    , direction = req.body.direction;
  req.device.scrollTo(element, text, direction, getResponseHandler(req, res));
};
