1How to merge all sms came from a sender into one in a ListView, like in the default messaging app?
2public class MessageList extends ListActivity {
3
4    protected void onCreate(Bundle savedInstanceState) {
5
6        super.onCreate(savedInstanceState);
7        setContentView(R.layout.main);
8
9        inboxcursor = getContentResolver().query(Uri.parse("content://sms/inbox"),new String [] {"person","address","body","date","_id","read", "status", "type", "reply_path_present", "subject","thread_id"} , null, null,"date DESC");
10        smsadapter = new MessageListAdapter(this,inboxcursor);  
11        getListView().setAdapter(smsadapter);
12}
13
14public class MessageListAdapter extends CursorAdapter {
15
16        Context mcontext;
17        LayoutInflater inflater;
18
19        public MessageListAdapter(Context context, Cursor cursor) {
20            super(context, cursor, true);
21
22            inflater = LayoutInflater.from(context);
23            mcontext = context;
24
25        }
26
27        @Override
28        public void bindView(View view, Context context, Cursor cursor) {
29
30             String number = cursor.getString(cursor.getColumnIndex("address"));
31             TextView numbertext = (TextView) view.findViewById(R.id.number);
32             numbertext.setText(number);
33
34             String message = cursor.getString(cursor.getColumnIndex("body"));
35             TextView messagetext = (TextView) view.findViewById(R.id.message);
36             messagetext.setText(message);
37
38        }
39
40        @Override
41        public View newView(Context context, Cursor cursor, ViewGroup parent) {
42
43            View view = inflater.inflate(R.layout.listitems, null);
44
45            return view;
46            }
47
48        }

50cursor = getContentResolver().query(<sms table, assuming all are incoming. if not, you need to filter it on your where clause>, new String[] {sender column name}, null, null, null};
51
52while(cursor.moveToNext()) {
53  String sender = cursor.getString(cursor.getColumnName(<sender column name>));
54  // check if the sender string exists in your arraylist. if not, create a new entry and set count to 1. else, get the position of the existing number and increment count by one.
55};
