java - AsyncTask keeps on giving output and updating my list -


this asynctask code , using populate custom listview . think wrong code .this piece of code keeps on running , don't know how many times. @ end giving me right results after many updates on textview (designation). not degrading performance of application showing multiple updates on textview before reaching result.

i getting data in desig[0] variable , have on code .

data coming azure don't worry if not azure guy . me on java part.

one more thing whole code inside getview() method.

    final string[] desig = new string[1];                  try {                     mclient = new mobileserviceclient(                             "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",                             "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",                             getcontext());                      muser = mclient.gettable(user.class);                      new asynctask<void, void, boolean>() {                         @override                         protected boolean doinbackground(void... params) {                             try {                                 final mobileservicelist<user> result =                                         muser.where().field("name").eq(currentitem.getfrom()).select("designation").execute().get();                                     int counter=                                         muser.where().select("designation").execute().get().gettotalcount();                                 log.v("counteeeerr", string.valueof(counter));                                 (user item : result) {                                     // log.i(tag, "read object id " + item.id);                                     desig[0] = item.getdesignation();                                     log.v("finally designation is", desig[0]);                                   }                                 return true;                              } catch (exception exception) {                                 exception.printstacktrace();                                 return false;                             }                         }                          @override                         protected void onpostexecute(boolean avoid) {                             super.onpostexecute(avoid);                            // gb.setdesignation(desig[0]);                          if(avoid) {                             designation.settext(desig[0]);                         }                          }                 }.execute();

expected result:-

these 4 lines , expecting :-

finally designation is﹕ project head, mojokarma

finally designation is﹕ project head, mojokarma

finally designation is﹕ cfo , hp

finally designation is﹕ cfo , hp

i getting:-

you can see , getting same results again , again .let me know if want else .

  1. never put code inside getview() of adapter.

  2. you should data fetching in fragment/activity , pass data array in adapter

  3. this scenario correct, getview() called multiple time during it's life cycle, not in our control.
