I am trying to scroll down to the bottom of the screen to a UI block using UiSelector class but it’s not working as expected. Basically, when I run the code it does not scroll all the way to the bottom rather it the first pulls (sort pull to refresh) and then starts scrolling but stops in the middle of the screen and then it goes back and forth and at some point it fails with an exception NoSuchElementException(attached a screen recording).
myDriver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable("
+ "new UiSelector().description(\"scrollview_train_tab\")).scrollIntoView("
+ "new UiSelector().textMatches(\"Games\"));"));
Here, myDriver is an instance of AndroidDriver.
I have tried with the followings methods in UiSelector class: text(), textContains(),description(), textMatches() but no luck. All of these are resulting in the same behaviour.
Please check this screen recording
Appium Client/Version: Java/7.3.0
Can anybody help? Thanks in advance.
@Aleksei hoping you can help me out.
try to increase number of swipes first (setMaxSearchSwipes). also visit guide which should help in many cases -> http://appium.io/docs/en/writing-running-appium/tutorial/swipe-tutorial/
Thank you for the replay. Really appreciate this.setMaxSearchSwipes but no luck. Besides, I also tried all the solution from http://appium.io/docs/en/writing-running-appium/tutorial/swipe-tutorial/
Code snippet used:driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().description(\"content-desc\")).setMaxSearchSwipes(10)" + ".scrollIntoView(new UiSelector().text(\"text_to_match\"))"));
Could there be an issue with the layout? Below is the inspected layout of the screen.
pls attach result of:System.out.println(driver.getPageSource())
Here is the page source:pageSource.log (19.5 KB)
try:
// 1
driver.findElement(MobileBy.AndroidUIAutomator(
"new UiScrollable(new UiSelector().scrollable(true).instance(0))" +
".scrollIntoView(new UiSelector()" +
".textMatches(\"" + elementText + "\").instance(0))"));
// 2
driver.findElement(MobileBy.AndroidUIAutomator(
"new UiScrollable(new UiSelector().scrollable(true).description(\"content-desc\"))" +
".scrollIntoView(new UiSelector()" +
".textMatches(\"" + elementText + "\").instance(0))"));
// 3
driver.findElement(MobileBy.AndroidUIAutomator(
"new UiScrollable(new UiSelector().scrollable(true).instance(0))" +
".setSwipeDeadZonePercentage(50).scrollIntoView(new UiSelector()" +
".textMatches(\"" + elementText + "\").instance(0))"));
// 4 final solution when nothing helps -> switch to:
// scrollForward (moves exactly one view)
try {
driver.findElement(MobileBy.AndroidUIAutomator(
"new UiScrollable(new UiSelector().scrollable(true)).scrollForward()"));
} catch (InvalidSelectorException e) {
// ignore
}
// and quickly check text needed appeared
// repeat scrollForward + text check in loop with some limit e.g. 10 tries.
Thank you. I really appreciate your help. The first 3 didn’t help. 4th solution didn’t work as well. However, I made a little adjustment then it worked.driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector().description(\""+parentScrollViewId+"\")).scrollForward()"));
Scroll up:driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector().description(\""+parentScrollViewId+"\")).scrollBackward()"));
Your adjustment is correct. I just copied code like basic idea. Good. Try same adjustment with 1 2 and 3
@Aleksei I tried but none of them work.
boolean elementFound = false;
while(elementFound==false) {
try {
if(mobEl.isDisplayed()==true) {
break;
}
}catch(Exception e) {
elementFound=false;
}
waitForEvent(2);
driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector().description(\"scrollview_learn_tab\")).scrollForward()"));
}
Here is the error log

Any idea what could be the reason?

You should ignore scrollForward errors like in example i wrote with try-catch.
Plus after scroll you should search for element again! But you checking that some old found element displaying.

Thank you so much. That was so silly about them.
public void scrollUntilElementFound(AppiumDriver<?> driver, MobileElement elementScrollTo,String parentScrollViewId) {//Scrolls until element is found
boolean elementFound = false;
while(elementFound==false) {
try {
if(elementScrollTo.isDisplayed()==true) {
break;
}
}catch(Exception e) {
elementFound=false;
}
try {
driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector().description(\""+parentScrollViewId+"\")).scrollForward()"));
}catch(Exception e) {
//Ignore error
}
}
}
@Aleksei
I found that If I only use the scrolling code snippet for example, the below line then the scrolling is fast enough (1.5 seconds between two scrolls). So I assume it’s the text search part that is causing the delay.
driver.findElement(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector().description(\""+parentScrollViewId+"\")).scrollForward()"));

Log each action. What cause it.
