Implement your custom adapter parametrized with GetReminder. Take a look here for example. Than you can do something like this:

ArrayList<GetReminder> list = (ArrayList<GetReminder>) getIntent().getSerializableExtra("reminderList");
ListView listView = findViewById(R.id.listview);
MyCustomAdapter adapter = new MyCustomAdapter(this, 0);
adapter.addAll(list)

or just pass your list as a third parameter in MyCustomAdapter constructor.

i am going to get messages from list like...list.get(i).getMessage(); and they are 'n' number of messages to be displayed in list,whether your code will work out?

Please, check getView method in example was given by me. Each call of this method represent 1 row in your list. Here you have to write your realisation how to show information from your list in your ListView.

You can do

setListAdapter(new ArrayAdapter<GetReminder>(getApplicationContext(), R.layout.reminderlayout,(GetReminder[]) list.toArray()));

considering this code is in onCreate() method of your class that extends ListActivity

In that case iterate over your list get all messages store in in an array and pass that to the Adapters constructor.
