scrollTo will be fixed in the Java bindings soon. There’s an open issue.

I’m too waiting for this fix, also is there any addition is going to come for scrollTo a element [by id/xpath] for the dynamic content [since no permanent text is available] !

Well i agree with @p00j4 scroll to an element by say (findElementByAccessibilityId)/xpath would be the best way.

I think that is fix with new java client. Kindly upate your pom.xml and add java client dependencied.

<dependency>
<groupId>io.appium</groupId>
<artifactId>java-client</artifactId>
<version>2.0.0</version>
</dependency>

Hello, I didn’t want to create a new thread since this seems very similar to the issue im having.

I am trying to scroll on Android physical device using this method ( in Ruby ):

execute_script “mobile: scrollTo”, :element => find_element(:name, “ELEMENT NAME”).ref

I’ve also tried scrolling using just coordinates AND swiping - still nothing.

Wanted to see if anyone could give me any advice on how to do this better? Or if anyone else is having any issues with scrolling on Android?

I have modified below method for java and it works

public WebElement scrollTo(String text) {
    String uiScrollables = "new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().textContains(\""+text+"\").instance(0))";
    return driver.findElementByAndroidUIAutomator(uiScrollables);
  }
