Increement issue in android -


i want increase value of "unit" in question

public void fetchunit() { carddatabase carddb =new carddatabase(getapplicationcontext()); carddb.open(); cursor c=carddb.selectall(); // c.movetofirst(); c.movetofirst(); int count = c.getcount(); log.e("card", c.getstring(0)); inflaterecord(c.getstring(0),c.getstring(1)); c.movetonext(); unit=c.getstring(0); c.close(); carddb.close(); } int count; public void getunit() { carddatabase carddb =new carddatabase(getapplicationcontext()); carddb.open(); cursor c=carddb.getrecord(unit); // c.movetofirst(); // c.movetofirst(); count = c.getcount(); log.e("card", c.getstring(0)); inflaterecord(c.getstring(0),c.getstring(1)); c.movetonext(); c.close(); carddb.close(); }

when call getunit() there no incremeant in "unit"....so give same value when call getunit()

public void bottom2top(view v) { // todo auto-generated method stub switch(v.getid()){ case r.id.img3: getunit(); break; } }

pleas suggest me do...thank all

when close cursor using c.close() lose information position of cursor.

you should either:

  • retreive specific record using primary key

or

  • retrieve records , return them arraylist

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
