Hi All,

1. I am unable to use the scroll to text function. When executed the function merely scrolls down about 100 pixels and stops. It does not scroll to the specified text.

2. I am therefore using the Swipe function to scroll down and using the following coordinates:

StartX: 1000  
StartY: 0  
EndX: 100  
EndY: 100

Using the inverse of this does not work to scroll up e.g.

StartX: 1000  
StartY: 100  
EndX: 100  
EndY: 0

Can you help me use the scroll to text function or explain what I am doing wrong with the swipe function.

Kid regards,

Patrick

I found that Mobile.scrollToText(‘My Label’) didn’t work well on Android when the drop down list was longer than one screen. It would scroll a bit, then stop, never finding my required item.

To get around this, I had to extend Katalon by creating a Custom Keyword to handle scrolling - this relies on the AppiumDriver library (thanks to [Nhi Dinh](http://forum.katalon.com/profile/1694/Nhi%20Dinh) for the sample code):

Create a new keyword file:

```auto
package com.my.keywords.android

import com.kms.katalon.core.mobile.keyword.internal.MobileDriverFactory
import io.appium.java_client.AppiumDriver

class swiping {	
	AppiumDriver driver;	
	
	swiping() {		
		this.driver = MobileDriverFactory.getDriver()	
	}	
	
	private scrollEntireList() { // very specific to android and the type of element that makes up your dropdowns		
		ArrayList listElement = driver.findElementsByClassName("android.widget.TextView")		
		TouchAction touchAction = new TouchAction(driver)		
		def bottomElement = listElement[listElement.size() - 1]		
		def topElement = listElement[0] // Press and scroll from the last element in the list all the way to the top		
		touchAction.press(bottomElement).moveTo(topElement).release().perform();	
	}	

@Keyword	
def boolean scrollListToElementWithText(String elementText) 
{		
	boolean isElementFound = false;		
	while (isElementFound == false) { // very specific to android and the type of element that makes up your dropdowns					
	
		ArrayList listElement = driver.findElementsByClassName("android.widget.TextView")			
		for (int i = 0; i<listElement.size(); i++) {				
			String textItem = listElement[i].getText()				
			if (textItem == elementText) {					
				isElementFound = true;					
				return true;				
				}			
		}			
		
		scrollEntireList()		
	}	
}}

```

Then in your test, you can use the Custom Keyword like:

```auto
CustomKeywords.'com.my.keywords.android.swiping.scrollListToElementWithText'('My Label')

```

Hi Joko,

It’s likely then that the element classes in your list aren’t of type `android.widget.CheckedTextView` as in the example code above. The index error is indicating that there are no elements found in the `listElement` array, so something on the screen doesn’t match the code.

They could possibly be `android.widget.TextView`. Can you try changing the code you pulled from above to use `android.widget.TextView` instead (make sure you change both places in the code from above)?

Alternatively, I used the code sample above as a basis for an open source library that helps with several complicated tasks in Katalon Studio tests. For example, here is a section that should make scrolling easier:

> **[GitHub - detroit-labs/katalon-mobile-util: Library of utilities to make...](https://github.com/detroit-labs/katalon-mobile-util#scrolling)**
>
> Library of utilities to make mobile UI testing in Katalon Studio easier - GitHub - detroit-labs/katalon-mobile-util: Library of utilities to make mobile UI testing in Katalon Studio easier

If you’re interested in using this library, here’s some Katalon documentation on using third party libraries:

[https://docs.katalon.com/katalon-studio/tutorials/import\_java\_library.html](https://docs.katalon.com/katalon-studio/tutorials/import_java_library.html)

You can get the library jar file at:

[https://github.com/detroit-labs/katalon-mobile-util/releases/download/1.9.0/katalon-mobile-util-1.9.0.jar](https://github.com/detroit-labs/katalon-mobile-util/releases/download/1.9.0/katalon-mobile-util-1.9.0.jar)

Hope this helps,

Chris

Hi Yudi,

From the error, it looks like the library couldn’t find a `TextView` element with the `text` ‘Album’. This could be for a couple of reasons:

1. The elements you’re trying to scroll through haven’t appeared on the screen yet
2. The element types you’re trying to scroll don’t contain the class `TextView`
3. There are other elements on the screen, like buttons, that are also detected as `TextView`, but they aren’t part of the scrolling list. If they’re static elements, like buttons, then the scroll action doesn’t work on them and the scrolling has no effect.

In any of these cases, some more info would be helpful for troubleshooting:

- Can you provide a screenshot of the screen you’re trying to test with the scrolling? A picture of what the Katalon Mobile Spy shows would be helpful, so that I can see how the elements are detected.
- Secondly, the `katalon-mobile-util` library has some built-in logging that can give a litle more info about how it’s working.

To do that, at the top of your test, import some of the `Logging` classes:

```auto
import com.detroitlabs.katalonmobileutil.logging.Logger
import com.detroitlabs.katalonmobileutil.logging.Logger.LogLevel

Logger.initialize('/tmp/mytest.log', LogLevel.DEBUG)

```

Now, if you open the file `/tmp/mytest.log`, you’ll see a running log of what `katalon-mobile-util` is doing, including the elements that it sees on the screen when doing scrolling. NOTE: You can change the log location to somewhere else that’s more convenient for you just by changing the first argument to `Logger.initialize`.

If you can provide the log and images from above, I think it will give me a better idea of why the scrolling isn’t working.

Thanks,

Chris

Here are my scripts:

CustomKeywords.‘utils.Swiping.scrollListToElementWithText’(‘Album’)

I got an error as follows:

How can I get the log path for ‘/tmp/katalon.log’ ?

Hi Yudi,

Sorry, I assumed you were on a Mac. If you’re on Windows, you should be able to set the path for the log to something like: `Logger.initialize('c:\mytest.log', LogLevel.DEBUG)`. Let me know if that works any better.

Hi Yudi,

Thanks for providing the log file and screenshots - they are very helpful. I think the issue is that the `Scroll.scrollListToElementWithText` function is made to scroll a list of similar elements, like a bunch of elements in a drop-down list. In your case, it looks like you want to scroll the entire screen until you find a certain element.

The `katalon-mobile-util` library doesn’t have anything for that (yet), but there should be ways to do it using the regular Katalon functions:

Documentation on the `Mobile.swipe` function:  
[https://docs.katalon.com/katalon-studio/docs/mobile-swipe.html#description](https://docs.katalon.com/katalon-studio/docs/mobile-swipe.html#description)

Hi @spulipati01,

I have an open source library to help with common, but complicated, things like scrolling. You can check out the documentation on scrolling in particular, here:

> **[detroit-labs/katalon-mobile-util](https://github.com/detroit-labs/katalon-mobile-util#scrolling)**
>
> Library of utilities to make mobile UI testing in Katalon Studio easier - detroit-labs/katalon-mobile-util

For instructions on how to install it, see here: [https://github.com/detroit-labs/katalon-mobile-util#installation](https://github.com/detroit-labs/katalon-mobile-util#installation)

If you’re still having problems, can you please share a screenshot of the screen you’re trying to scroll and the properties (taken from Mobile Spy) of the object you’re trying to scroll to.

Thanks,

Chris
