search - Searching a custom listview using an ArrayAdapter in Android -

i have custom listview has 2 textviews , 1 imageview in it. uses custom arrayadapter it's adapter, , wanted add search function it. i've looked through every single tutorial find, no luck. 1 tutorial able search through regular listview (not using custom adapter), not work me because need show both textviews , imageview. need filter 1 of textviews though, don't see how trouble be.

anyway, here mainactivity:

public class itemid extends activity {      // list view     private listview lv;      // listview adapter     arrayadapter<string> adapter;      // search edittext     edittext inputsearch;       // arraylist listview     arraylist<hashmap<string, string>> productlist;      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.testo);          context ctx = getapplication();         resources res = ctx.getresources();          string[] options = res.getstringarray(r.array.item_names);          lv = (listview) findviewbyid(r.id.list_view);         inputsearch = (edittext) findviewbyid(r.id.inputsearch);          // adding items listview         adapter = new arrayadapter<string>(this, r.layout.list_item_test, r.id.product_name, options);         lv.setadapter(adapter);          /**          * enabling search filter          * */         inputsearch.addtextchangedlistener(new textwatcher() {              @override             public void ontextchanged(charsequence cs, int arg1, int arg2, int arg3) {                 // when user changed text                 itemid.this.adapter.getfilter().filter(cs);                }              @override             public void beforetextchanged(charsequence arg0, int arg1, int arg2,                     int arg3) {                 // todo auto-generated method stub              }              @override             public void aftertextchanged(editable arg0) {                 // todo auto-generated method stub                                       }         });     }     } 

and here custom adapter:

public class itemidadapter extends arrayadapter<string> implements filterable {      public layoutinflater minflater;      public string[] mstrings;     public string[] mids;     public typedarray micons;        public int mviewresourceid;      public itemidadapter(context ctx, int viewresourceid,             string[] strings, string[] ids, typedarray icons) {         super(ctx, viewresourceid, strings);          minflater = (layoutinflater)ctx.getsystemservice(                 context.layout_inflater_service);          mstrings = strings;         mids = ids;         micons = icons;                mviewresourceid = viewresourceid;     }      @override     public int getcount() {         return mstrings.length;     }      @override     public string getitem(int position) {         return mstrings[position];     }      @override     public long getitemid(int position) {         return position;     }        @override     public view getview(int position, view convertview, viewgroup parent) {         convertview = minflater.inflate(mviewresourceid, null);          imageview iv = (imageview)convertview.findviewbyid(r.id.option_icon);         iv.setimagedrawable(micons.getdrawable(position));          textview tv = (textview)convertview.findviewbyid(r.id.option_text);         tv.settext(mstrings[position]);          textview tv1 = (textview)convertview.findviewbyid(r.id.itemids);         tv1.settext(mids[position]);          return convertview;     }   } 

hopefully can me, has been tedious challenge because i'm new android development, , i'm out of options. help!

in oncreate():

 inputsearch = (edittext)findviewbyid(r.id.inputsearch);          inputsearch.addtextchangedlistener(new textwatcher() {               @override              public void ontextchanged(charsequence cs, int arg1, int arg2, int arg3) {                  // when user changed text                  youradaptername.getfilter().filter(cs);                 }               @override              public void beforetextchanged(charsequence arg0, int arg1, int arg2,                      int arg3) {                  // todo auto-generated method stub               }              @override             public void aftertextchanged(editable s) {                 // todo auto-generated method stub              }          }); 

and in layout:

<edittext android:id="@+id/inputsearch"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:hint="search.."         android:inputtype="textvisiblepassword"/>
