you can use setter/getter method for it.

public class MySetGet
{
    private ArrayList aList = null;

    public void setList ( ArrayList aList )
    {
            this.aList = a.List;
    }

    public ArrayList getList () 
    {
        return aList;
    }
}

Now you can set its value from any Activity/Class and get its value from any Activity/Class.

The most simply and possible way to do the desired::

1.Create a simple public class say Data.. Now create a public static your Array list object.

Now access any where..

Data.listObj

2.Create the List object as public static in one activity and use in another via,

SecondActivity.listObj.clear();
