java - sharedpreferences stringset value: How to remove in Android Studio.? -


i have unchecked checkbox(per item) remove . using sharedpreferences hashset concept. want pass arraylist value 1 page page. what mistake 1 me.

my code is:

adapterpage.java  public static final string my_prefs_name = "";   @override     public void onclick(view view) {              boolean ischecked = mainholder.chekenitem.ischecked();              // arr=getresources().getstringarray(  mainholder.txtenimgid.gettext().tostring());             //  boolean ischecked = mainholder.chekenitem.ischecked();             int i;             string itemid1 = mainholder.txtenimgid.gettext().tostring();         sharedpreferences prefs=view.getcontext().getsharedpreferences(my_prefs_name,context.mode_private);         sharedpreferences.editor edit=prefs.edit();         set<string> set = new hashset<string>();         try {             if (ischecked) {                   addmembers.add(itemid1);                  (j = 0; j < addmembers.size(); j++) {                     set.addall(addmembers);                    edit.putstringset("yourkey", set);                    edit.commit();                    toast.maketext(view.getcontext(), "clicked on checkbox addmembers[pos] : " + addmembers.get(j) + " item id " + itemid1                            , toast.length_long).show();                 }                      //   editor.putstring("key_name",itemid );                     // editor.apply();                //  }              } else {                 for(int k=0;k<=addmembers.size();k++){                     if(addmembers.get(k).equals(itemid1)){                       //  set.remove(addmembers);                         addmembers.remove(k);                         edit.remove(addmembers.get(k));                         edit.commit();                          break;                     }                   }

you making mistake here ...

 (j = 0; j < addmembers.size(); j++) { //set.addall(addmembers);this add every time whole data of list set     set.add(addmembers.get(j));                    edit.putstringset("yourkey", set);                    edit.commit();                    toast.maketext(view.getcontext(), "clicked on checkbox addmembers[pos] : " + addmembers.get(j) + " item id " + itemid1                            , toast.length_long).show();                 }

and here while removing change this... edit.remove("yourkey");
