Calendar DatePicker: Keeps scrolling up and down

vsharma · Nov '18

Hello Friends,

I am new B to appium so need guidance of this case,using Java Programming language
Java Client - 6.1,Appium Server - 1.8
Trying to scroll on a calendar to select a particular year
After reading forums tried below but not working

WebElement element = driver.findElement(MobileBy.AndroidUIAutomator(
“new UiScrollable(new UiSelector().resourceId(“android:id/date_picker_year_picker”)).getChildByText(”

“new UiSelector().className(“android.widget.TextView”), “1981”)”));

The scrolling happens it scrolls up then down then up and gives error but expected is not selected.

e[36minfoe[39m: [debug] [BOOTSTRAP] [debug] Returning result: {“status”:9,“value”:“Could not parse UiSelector argument: problem using reflection to call this method”}
org.openqa.selenium.UnsupportedCommandException: The requested resource could not be found, or a request was received using an HTTP method that is not supported by the mapped resource.

the problem is that 1981 is not visible while automation tries to find it. as result you have such result.

try compare your value and scroll yourself e.g.:

// just flingForward
driver.findElement(MobileBy.AndroidUIAutomator(
   "new UiScrollable(new UiSelector().resourceIdMatches(\".*id/date_picker_year_picker\")).flingForward()"));
// or flingBackward
driver.findElement(MobileBy.AndroidUIAutomator(
   "new UiScrollable(new UiSelector().resourceIdMatches(\".*id/date_picker_year_picker\")).flingBackward()"));

now check again current value and decide scroll again or we can now tap needed element.

Thank You Aleksei for inputs.However it gives the below in logs, the fling happens on device though

I have few more queries but once this resolves I shall raise.

Thanks

My solution for calendar selection: Open the date picker, tap on year, then I get the index of elements from the list, I check if the expected text is present, if not I swipe from the last item in the list till the first one. and so on till the element is found and tapped.
Define elements per your case

  public void selectDate() {
	register.birthDate.click();
	general.datePickerYear.click();
	u.swipeInListTillExpectedTextAndTap(general.yearList, "1991", 20);
	general.datePickerNextButton.click();
	general.datePickerDay.click();
	general.datePickerOK.click();
}

public void swipeInListTillExpectedTextAndTap(List<MobileElement> list, String expectedText, int time) {
	int i = 1;
	while (!driver.getPageSource().contains(expectedText)) {
		swipeInListFromLastToFirst(list);
		i++;
		if (i == time)
			break;
	}
	tap(driver.findElementByAndroidUIAutomator("new UiSelector().textContains(\"" + expectedText + "\")"));
}

public void swipeInListFromLastToFirst(List<MobileElement> listID) {
	int items = listID.size();
	org.openqa.selenium.Point centerOfFirstElement = listID.get(0).getCenter();
	org.openqa.selenium.Point centerOfLastElement = listID.get(items - 1).getCenter();
	new TouchAction<>(driver).longPress(point(centerOfLastElement.x, centerOfLastElement.y))
			.moveTo(point(centerOfFirstElement.x, centerOfFirstElement.y)).release().perform();
}

Let me know if helps.

@Zuzeac. My mistake. Replace ‘date_picker_year_picker’ with locatorID of listView. Upper element on your screenshot.

Hi @Aleksei,
Didn’t know that we can user flingForward and backward. Good to know, thanks. Where can i find documentation for all UiSelector’s method? would like to research.
Nevertheless, I’m getting same error as @vsharma: Could not parse UiSelector argument: methods must return UiScrollable or UiObject instances.
The driver will scroll a bit then throw error.
I tried with different resource id’s, I don’t get it why.

Hi @Zuzeac I am lost… please advise for the below
1)The logs shows out of bound for display, I noticed that when I printed the list size it is 1 is that causing this? The text for the list falls under different class…
List e1=driver.findElements(By.xpath("//*[@class=‘android.widget.ListView’]"));
Below is printed in log
System.out.println(centerOfFirstElement); > (360, 661)
System.out.println(centerOfLastElement); > (360, 661)
When Year is lauched in clicks on centre

Hi @Aleksei you mentioned in comment above replace ‘with locatorID of listView’ I had used the locator id of the list…is anything else you were refering too?

Zuzeac · Nov '18

@vsharma The list is
android:id/text1
List e1=driver.findElements(By.id("android:id/text1"));

vsharma · Nov '18

My Bad…
You caught it right @Zuzeac…Thanks “Guru” was trying this for last 1 week as practice.

Thanks @Aleksei for ur support as usual.
