android - How to setup Listview to strikethrough item after click? -

i have list of strings setup on listview in on create:

//set adapter lvadapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, chosenarray); //add listview lw.setadapter(lvadapter); 

my question:

i want setup list once item clicked, gets strike through. however, new android , haven't done before.

what i've tried unsuccessfully:

based on answer tried method, cross off items not visible in list well.

lw.setonitemclicklistener(new adapterview.onitemclicklistener() {   @override   public void onitemclick(adapterview<?> parent, view view, int position, long id) {       //cross off      textview text = (textview) view;      text.setpaintflags(text.getpaintflags() | paint.strike_thru_text_flag);        }    }); 

i've read there maybe way extend arrayadapter, have never done before. ideas?

update: since we're running issues, here's whole code. it's within oncreate:

public  arrayadapter<string> lvadapter; public arraylist<string> arrplayers = new arraylist<string>();   @override protected void oncreate(bundle savedinstancestate) {  super.oncreate(savedinstancestate);  setcontentview(r.layout.activity_pool_sheet);   //setup list view  listview lw = (listview) findviewbyid(r.id.lvbouts);   //adapter use on listview  string[] chosenarray = {""};   //convert  if (extras != null) {   arrplayers = extras.getstringarraylist("arrplayers");  }    //based on array input size main activity  //select pre defined string arrays  switch (arrplayers.size()) {    case 6:       chosenarray = poolofsix;       break;    case 7:        chosenarray = poolofseven;        break;    case 8:         chosenarray = poolofeight;         break;    case 9:         chosenarray = poolofnine;         break;    case 10:         chosenarray = pooloften;         break;         //no need default since multiple choice     }    //set adapter  lvadapter = new arrayadapter<string>this,android.r.layout.simple_list_item_1,                chosenarray);  lw.setadapter(lvadapter);   //list view onclick listener  lw.setonitemclicklistener(new adapterview.onitemclicklistener() {     @override     public void onitemclick(adapterview<?> parent, view view, int position, long id) {     //cross off     textview text = (textview) view;     text.setpaintflags(text.getpaintflags() | paint.strike_thru_text_flag);      }); } 

here's behavior has:

update:

you want use custom adapter then. instantiate list view this:

adapter = new customadapter(yourarrayhere);     listview.setadapter(adapter); 

then create custom adapter so:

private class customadapter extends baseadapter {      private string[] strings;     private arraylist<string> selectedstrings;      public customadapter(string[] strings) {         this.strings = strings;         selectedstrings = new arraylist<>();     }      @override     public int getcount() {         return strings.length;     }      @override     public string getitem(int i) {         return strings[i];     }      @override     public long getitemid(int i) {         return 0;     }      @override     public view getview(int i, view view, viewgroup viewgroup) {         viewholder holder;         if (view == null) {             holder = new viewholder();             view = layoutinflater.from(viewgroup.getcontext()).inflate(android.r.layout.simple_list_item_1, viewgroup, false);             holder.text = (textview) view;             view.settag(holder);         } else {             holder = (viewholder) view.gettag();         }         holder.text.settext(getitem(i));         if (selectedstrings.contains(getitem(i))) {             holder.text.setpaintflags(holder.text.getpaintflags() | paint.strike_thru_text_flag);         } else {             holder.text.setpaintflags(0);         }         return view;     }      private class viewholder {         textview text;     }      public arraylist<string> getselectedstrings() {         return selectedstrings;     } } 

then new click like:

@override         public void onitemclick(adapterview<?> adapterview, view view, int i, long l) {             adapter.getselectedstrings().add(list[i]);             adapter.notifydatasetchanged();         } 

now selectedstrings array list contains of strings have selected.

try this:

@override         public void onitemclick(adapterview<?> adapterview, view view, int i, long l) {             textview text = (textview) view;             text.setpaintflags(text.getpaintflags() | paint.strike_thru_text_flag);         } 

the first line getting row's view (which text view, due using simple list item 1). if using custom view, layout images , text view, need add:

textview text = (textview)view.findviewbyid(r.id.my_text_view);
