---   --------- -----------   ----- -----
1     Pen        10-10-2012      10    10
2     abc        10-10-2012      30    45
3     xyz        11-10-2012      15    55
4     ggg        11-10-2012      20    75
5     aaa        12-10-2012      10    85
6     nnn        13-10-2012      10    95

But along with i want to only same date records in one row and related Camt
will be added for same date Camt and output will be appears like :

DATE             AMOUNT
------------     ------
10-10-2012          40
11-10-2012          35
12-10-2012          10
13-10-2012          10

I have coded for regarding requirement using cursor and SimpleCursorAdapter but still i can't get appropriate result.

this output will be get in simple Sql query like :
SELECT CAST(Date AS DATE),SUM(Camt) AS AMOUNT from tb_expense GROUP BY CAST(Date AS DATE);

C#

Cursor c = db.query("tb_expense", new String[] {"Date", "SUM(Camt) AS Amount" }, null, null, "Date", null, null, null);
adapter = new SimpleCursorAdapter(this, R.layout.myrow1, c, new String[]{"Date","Camt"},new int[]{R.id.textView3,R.id.textView5} );
startManagingCursor(c);
lstExpense.setAdapter(adapter);

this problem solved by myself :

C#

Cursor c = db.query("tb_expense", new String[] 
       {DbHelper.C_Expno,"Group_Concat(ExpName) AS 
       ExpName","Date","SUM(Camt) AS Camt"}, null, null, "Date", null, null);

adapter = new SimpleCursorAdapter(this, R.layout.myrow1, c, new String[]
       {DbHelper.C_Expno,"ExpName","Date","Camt"},new  
       int[]{R.id.lblexpno,R.id.lblexpnm,R.id.lbldt,R.id.lblcamt} );

startManagingCursor(c);
lstExpense.setAdapter(adapter);
