Get specific ArrayList item
JavaArraylistJava Problem Overview
public static ArrayList mainList = someList;
How can I get a specific item from this ArrayList? mainList[3]?
Java Solutions
Solution 1 - Java
As many have already told you:
mainList.get(3);
Be sure to check the ArrayList Javadoc.
Also, be careful with the arrays indices: in Java, the first element is at index 0. So if you are trying to get the third element, your solution would be mainList.get(2);
Solution 2 - Java
Time to familiarize yourself with the ArrayList API and more:
ArrayList at Java 6 API Documentation
For your immediate question:
mainList.get(3);
Solution 3 - Java
mainList.get(list_index)
Solution 4 - Java
mainList.get(3);
For future reference, you should refer to the Java API for these types of questions:

Solution 5 - Java
We print the value using mainList.get(index) where index starts with '0'. For Example: mainList.get(2) prints the 3rd element in the list.

Solution 7 - Java
Try:
ArrayListname.get(index);
Where index is the position in the index and ArrayListname is the name of the Arraylist as in your case is mainList.
Solution 8 - Java
I have been using the ArrayListAdapter to dynamically put in the entries into the respective fields ; This can be useful , for future queries
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();
And then , you can fetch any arraylist item as below :
arrayListName(info.position);
