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.

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);

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);

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.

mainList.get(3);

For future reference, you should refer to the Java API for these types of questions:
