ArrayList object not passing to String[]

[Tom Mordon]

When I add items from ArrayList<Item> -> to String[], an object gets passed but when I run the app in the emulator it shows the object as an address of sorts in the ListView. In the debugger it shows the cell to be null. Been stuck on this part as to why its not showing the null value that was passed from the array list to the string[]. This stems from the addItem(String sItem) method. Below is a link to image of the error.

Figured it out, needed to use .phrase; instead of toString()
