android - Reading private field in OnCreateDialog -

i'm writing application shows 2 buttons in alert dialog, 1 select objects, other show details.

i evaluate if map new items selected has values but, clearing map, condition returns false.

here code of oncreatedialog() , asynctask call dialog:

// map containing objects selected map<string, identifyresult> itemsselected = new hashmap<string, identifyresult>();  // map containing new objects selected map<string, identifyresult> longclicktemp = new hashmap<string, identifyresult>();  protected class identifyfeatures extends         asynctask<identifyparameters, void, identifyresult[]> {      identifytask identifier;     progressdialog progress;      @override     protected identifyresult[] doinbackground(identifyparameters... params) {         identifyresult[] result = null;          if (params != null && params.length > 0) {             identifyparameters usedparams = params[0];             try {                 result = identifier.execute(usedparams);             } catch (exception e) {                 e.printstacktrace();             }         }         return result;     }      @override     protected void onpreexecute() {         identifier = new identifytask(layer2.geturl());         progress=progressdialog.show(aep41activity.this, "chargement", "récupération de la sélection");         super.onpreexecute();     }      @override     protected void onpostexecute(identifyresult[] result) {         if (result != null && result.length > 0) {              toast t = toast.maketext(aep41activity.this, result.length                     + " objects trouves", toast.length_short);             t.show();              aep41activity.this.longclicktemp.clear();             // highlight features selected              (int = 0; < result.length; i++) {                 // verify if object selected                 if (itemsselected.containskey(result[i].getattributes()                         .get("objectid"))) {                     log.d("object exists", "id: "                             + result[i].getattributes().get("objectid"));                     continue;                 }                 log.d("object found",                         "object type: " + result[i].getlayername()                                 + " id: "                                 + result[i].getattributes().get("objectid"));                  aep41activity.this.longclicktemp.put(                         (string) result[i].getattributes().get("objectid"),                         result[i]);             }             progress.dismiss();             aep41activity.this.showdialog(context_menu_select);         } else {             progress.dismiss();             toast t = toast.maketext(aep41activity.this,                     "aucun objet trouve", toast.length_short);             t.show();         }     } }  @override protected dialog oncreatedialog(int id) {     alertdialog.builder builter = new alertdialog.builder(             aep41activity.this);      switch (id) {     case context_menu_select:         builter.settitle("selectionner option");         if(!longclicktemp.isempty()){             builter.setpositivebutton("selectionner", new dialoginterface.onclicklistener() {                  @override                 public void onclick(dialoginterface dialog, int which) {                     itemsselected.putall(longclicktemp);                     updateselectedmenu();                 }             });         }         builter.setneutralbutton("details", new dialoginterface.onclicklistener() {              @override             public void onclick(dialoginterface dialog, int which) {                 bundle b = new bundle();                 b.putstringarraylist("selectedids", utilities.getstringarray(itemsselected.keyset()));                 b.putserializable("tabvalues", utilities                         .getidentifyresultarray(longclicktemp));                 intent = new intent(aep41activity.this,                         fielddetails.class);                 i.putextras(b);                 startactivity(i);             }         });         break; 

it problem of cached dialog.

i didn't know dialog cached in android.

to solve problem, added:

removedialog(context_menu_select);

before aep41activity.this.showdialog(context_menu_select);
