Answer 1

you can use a rawQuery if you want like this:

Cursor c=db.rawQuery("select Max(ExpNo) from table", null);
txtExpno.setText(c.getString(c.getColumnIndex("ExpNo")));

or you can use the standard android query also like this:

Cursor c=db.query("tb_expense",exno,"MAX(ExpNo)",null,null,null,null);
txtExpno.setText(c.getString(c.getColumnIndex("ExpNo")));
