[java] Get specific ArrayList item

public static ArrayList mainList = someList;

How can I get a specific item from this ArrayList? mainList[3]?

mainList.get(list_index)

Time to familiarize yourself with the ArrayList API and more:

ArrayList at Java 6 API Documentation

For your immediate question:

mainList.get(3);

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.

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.

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);

You can simply get your answer from ArrayList API doc.

Please always refer API documentation .. it helps

Your call will looklike following :

mainList.get(3);

Here is simple tutorial for understanding ArrayList with Basics :) :
