android - Java ArrayList .add() overwrites previous values -


i've checked out other people facing same issue, & of them instantiating objects want add outside loop. i'm doing inside while loop, i'm guessing that's not issue.

public arraylist<shmaptile> tiles = new arraylist<shmaptile>(); . . . private void parsexml(xmlpullparser parser) throws xmlpullparserexception, ioexception {     int eventtype = parser.geteventtype();     int = 0;      while ( eventtype != xmlpullparser.end_document )     {         string name = null;          switch ( eventtype )         {             case xmlpullparser.start_tag:             {                 name = parser.getname();                  if ( name.equalsignorecase("tile") )                 {                     shmaptile tile = new shmaptile();                     tile.gid = i;                      tiles.add(tile);                     system.out.println("gid: " + tiles.get(0).gid);                     i++;                 }                  break;             }              case xmlpullparser.end_tag:             {                 name = parser.getname();                  if ( name.equalsignorecase("data") )                 {                     this.runonuithread(new runnable() {                         public void run() {                             drawcurrentmapregion();                         }                     });                 }                  break;             }         }          eventtype = parser.next();     } }

for debugging, attached counter each new object. when print out counter of first element in list, it's different. tried cloning. didn't work either.

as said in comments, field gid of class shmaptile static.

that means same value shared between all instances of class. if update one, updated in istances of class. remove static modifier , work

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
