this problem solved by myself :
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);
