Android : How can I display incoming and outgoing call recordings in one listview with different symbols in android

I am developing a application, in which incoming and outgoing calls will be recorded. I want to display incoming and outgoing call recordings in one list view and in that list view I want to show different images for incoming and outgoing because I want the user to know which is incoming and which is outgoing. So, how can I do that. Please any one can help me.
