Answer 1

you can do it in two ways,

1. Create a setter/getter class
2. Make a public static method that returns ArrayList

First Method:

class name : myDataObject.java

private ArrayList myArrayList;

// setting the ArrayList Value 
public void setArrayList ( ArrayList myArrayList )
{
     this.myArrayList = myArrayList;
}

// getting the ArrayList value 
public ArrayList getArrayList() 
{
     return myArrayList;
}

Second Method:

In ArrayList file, ( suppose class name is class A.java )

private static ArrayList myArrayList = null; 

... 
// assign arraylist 

public static ArrayList getArrayList()
{
      return myArrayList;
}

in the calling activity/class you can call it using following code,

private ArrayList newArrayList = null;

newArrayList = A.getArrayList();
