these 2 fragment allocated in main fragmentactivity , hide/show when it's necessary :

private void setfragment(fragment fragment) {     fragmenttransaction trans = getsupportfragmentmanager().begintransaction();     // if active fragment instance of accueilfragment hide 1       if(activefragment instanceof accueilfragment)     {         system.out.println("accueil fragment hide");         trans.hide(maccueilfragment);     }     // if active fragment instance of cataloguesfragment hide 1      if(activefragment instanceof cataloguesfragment)     {         system.out.println("ctalogue fragment hide");         trans.hide(mcataloguesfragment);     }     // if active fragment instance of magasinsfragment hide 1      if(activefragment instanceof magasinsfragment)     {         system.out.println("magasins fragment hide");         trans.hide(mmagasinsfragment);     }     // if active fragment instance of newsfragment hide 1      if(activefragment instanceof newsfragment)     {         system.out.println("news fragment hide");         trans.hide(mnewsfragment);     }     mlistfragments.add(fragment);     // set new active fragment     activefragment = fragment;     // show     trans.show(fragment);     // , commit transaction       trans.commit(); }
