strange behavior of indexing of list of LinearLayout element in Appium test writen with JAVA

Question

I am testing a local Android mobile application with Appium, tests are writen in Java.

In the following code I am trying to search for a certain item in a menu list in the app and click. The menu has altogether 4 items, but the listSize is read as 35, and the reading varies from execution to execution. Also, if I do a click on for example menuList.get(0).click(), in the execution it is the second item got the click instead of the first item.

Print out result listed below.

Appium version 1.4.13.1, JDK version 1.8.0_66. Not sure any other information could be relevant, please ask if you wonder.

List<WebElement> menuList = driver.findElementsByClassName("android.widget.LinearLayout");
    int listSize = menuList.size();
    int index = 0;
    Boolean menuFound = false;
    while(!menuFound && index < listSize)
    {
        String label = menuList.get(index).findElement(By.id("no.ruter.reise.qa:id/label")).getText();
        System.out.printf("%d of %d, %s\n", index, listSize, label);
        if (label.equals(menuItem)){
            menuList.get(index).click();
            System.out.printf("\t%s %s\n", menuItem, "click");
            menuFound = true;
        }
        index++;
    }

Print out result:

Answer 1

You are using "android.widget.LinearLayout" class which is common and your application has 35 layout which class name "android.widget.LinearLayout".

These layout may be in nested format. You need to create locator for menus, if your all menu locator has id "no.ruter.reise.qa:id/label" you can use below code:

List<WebElement> menuList = driver.findElementsByClassName("no.ruter.reise.qa:id/label");
int listSize = menuList.size();
int index = 0;
Boolean menuFound = false;
for(WebElement menu : menuList)
{
    String label = menu.getText();
    System.out.printf("%d of, %s\n", index,label);
    if (label.equals(menuItem)){
        menu.click();
        System.out.printf("\t%s %s\n", menuItem, "click");
        menuFound = true;
    }
    index++;
}
