Help: Printing a custom EditText into listview - Android Q&A, Help & Troubleshooting

I do not really know how to finish this code?
All i want is to print whatever is entered within the editText to be listed in listview.
I am creating a dice game app, and within the xml part I have 1 edittext (in which you can type the name of the player), 1 button for adding another player. Basically every time some1 types in a name I want it to show up in the list once the button "add" is pressed. Likewise as more players are added the list should expand. Im using a lot of youtube examples, however simply do not know how to finish the code exactly.
Any help would be much appreciated
