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

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? – jenil Mar 22 '15 at 08:44
In that case iterate over your list get all messages store in in an array and pass that to the Adapters constructor. – Aniket Thakur Mar 22 '15 at 08:46
u mean store in string[] – jenil Mar 22 '15 at 08:53
Yes if that's what `getMessage()` returns. – Aniket Thakur Mar 22 '15 at 09:05
it wil return me a string – jenil Mar 22 '15 at 09:09

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.

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. – Divers Mar 22 '15 at 08:46
ok ,i went through it,i even found the complete example at the end,but in that how to implement onClick event – jenil Mar 22 '15 at 10:04
You found? I gave you a link for complete example. 'listView.setOnItemClickListener' in order to assighn on item click listener. – Divers Mar 22 '15 at 11:13
i am following has you said http://stackoverflow.com/questions/8166497/custom-adapter-for-list-view last post from Louis,stil working on – jenil Mar 22 '15 at 14:43
RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list' ....,getting this exception – jenil Mar 22 '15 at 15:25
There is one more copy-past from some source without understanding (or even efforts) what are you doing. Can't help in this case. – Divers Mar 22 '15 at 15:42
yes i tried this code in a sample app on my side to understand,but after applying to my prj it caused issue...,i am a newbie to this android so i took over. – jenil Mar 22 '15 at 16:22
All this our discussion is not related to this question. If you have further question - ask it in separate one. This one is answered (at least I think so) – Divers Mar 22 '15 at 16:54
