i have annoying problem don't know how solve. problem straightforward:

i have fragmenta pushes fragmentb (a listview) on button click. in fragmentb can push fragmenta onitemclick. see, depth infinite.

the problem when pushed fragmentb second time, , go (2 times) first instance of fragmentb have items first , second instance in listview. if make 10 instances, have items of 10 instances in first instance.

can explain problem , please provide me solution?

edit (code snippet):

followersfragment frag = new followersfragment(); bundle bundle = new bundle(); bundle.putstring(constants.user_id, userid); frag.setarguments(bundle); ((mainactivity) getactivity()).pushfragment(frag);  public void pushfragment(trigdfragment fragment) {     pushfragment(fragment, new animationobject()); }  public void pushfragment(trigdfragment fragment, animationobject animate) {     switchcontent(fragment, animate, false); }  public void switchcontent(trigdfragment fragment, animationobject anim,         boolean clearbackstack) {     actionbarhelper mactionbarhelper = actionbarhelper.getinstance();     supportinvalidateoptionsmenu();     fragmentmanager mgr = getsupportfragmentmanager();      if (clearbackstack) {         mactionbarhelper.setdisplayhomeasdrawerenabled(true);         mgr.popbackstack(null, fragmentmanager.pop_back_stack_inclusive);     } else {         mactionbarhelper.setdisplayhomeasupenabled(true);     }      fragment.setupactionbar(getresources());      fragmenttransaction ft = mgr.begintransaction();      boolean doinganimation = false;     if (util.hasicecreamsandwich()) {         doinganimation = anim != null;          if (doinganimation) {             ft.setcustomanimations(anim.enterresource, anim.exitresource,                     anim.popenterresource, anim.popexitresource);         }     }     ft.replace(r.id.content_frame, fragment, "current");      if (!clearbackstack) {         ft.addtobackstack(null);     }      ft.commitallowingstateloss();      if (util.hasicecreamsandwich()) {         if (doinganimation) {             // can't done because transaction may             // not             // yet committed. commits are posted main             // thread's message loop.             mhandler.post(new runnable() {                 @suppresslint("newapi")                 @override                 public void run() {                     invalidateoptionsmenu();                 }             });         }     } }

instead of creating new instance of fragments can use replace function of fragmenttransaction

transaction.replace(r.id.fragment_container, newfragment);
