Trying to duplicate code in Demo for CWAC Touchlist and getting errors for Android -

i have been developing on 10 years in languages other java. new android world, i'm trying dive right in. trying make draggable list , found wonderful repos https://github.com/commonsguy/cwac-touchlist dragging , dropping of list items. however, getting error when trying @override drop method droplistener interface. states that: "the method drop(int, int) of type new touchlistview.droplistener(){} must override superclass method"

i tried implement way demo utilizes touchlist application, , copied code in action, , i'm getting same error.

my code:

package bu.homework.shoppinglist;  import android.app.listactivity; import android.content.intent; import android.database.cursor; import android.os.bundle; import android.view.contextmenu; import android.view.contextmenu.contextmenuinfo; import android.view.menu; import android.view.menuitem; import android.view.view; import android.widget.adapterview.adaptercontextmenuinfo; import android.widget.listview; import android.widget.simplecursoradapter;  import com.commonsware.cwac.tlv.touchlistview;  public class itemlistactivity extends listactivity {     private static final int activity_create=0;     private static final int activity_edit=1;      private static final int insert_id = menu.first;     private static final int delete_id = menu.first + 1;      private itemsmodel mdbhelper;      /** called when activity first created. */     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.item_list);         mdbhelper = new itemsmodel(this);         mdbhelper.open();         filllist();         touchlistview itemlistview = (touchlistview) getlistview();         itemlistview.setdroplistener(ondrop);         system.out.print("on drop");         // itemlistview.setremovelistener(onremove);         // registerforcontextmenu(itemlistview);     }     private touchlistview.droplistener ondrop = new touchlistview.droplistener() {         @override         public void drop(int from, int to) {             system.out.print(from);             system.out.print(to);         }     };      private touchlistview.removelistener onremove = new touchlistview.removelistener() {         public void remove(int which) {          }     };      @override     public boolean oncreateoptionsmenu(menu menu) {         boolean result = super.oncreateoptionsmenu(menu);         menu.add(0, insert_id, 0, r.string.menu_insert);         return result;     }      @override     public boolean onmenuitemselected(int featureid, menuitem item) {         switch(item.getitemid()) {             case insert_id:                 createitem();                 return true;         }          return super.onmenuitemselected(featureid, item);     }      @override     public boolean onoptionsitemselected(menuitem item) {         switch (item.getitemid()) {         case insert_id:             createitem();             return true;         }         return super.onoptionsitemselected(item);     }      @override     public void oncreatecontextmenu(contextmenu menu, view v,             contextmenuinfo menuinfo) {         super.oncreatecontextmenu(menu, v, menuinfo);         menu.add(0, delete_id, 0, r.string.menu_delete);     }      @override     public boolean oncontextitemselected(menuitem item) {         switch(item.getitemid()) {             case delete_id:                 adaptercontextmenuinfo info = (adaptercontextmenuinfo) item.getmenuinfo();                 mdbhelper.deleteitem(info.id);                 filllist();                 return true;         }         return super.oncontextitemselected(item);     }      @override     protected void onlistitemclick(listview l, view v, int position, long id) {         super.onlistitemclick(l, v, position, id);         intent = new intent(this, itemeditactivity.class);         i.putextra(itemsmodel.key_rowid, id);         startactivityforresult(i, activity_edit);     }      @override     protected void onactivityresult(int requestcode, int resultcode, intent intent) {         super.onactivityresult(requestcode, resultcode, intent);         filllist();     }      private void createitem() {         intent = new intent(this, itemeditactivity.class);         startactivityforresult(i, activity_create);     }      private void filllist() {         // of notes database , create item list         cursor itemcursor = mdbhelper.fetchallitems();         startmanagingcursor(itemcursor);          // create array specify fields want display in list (only name)         string[] = new string[] { itemsmodel.key_name };          // , array of fields want bind fields (in case item_row)         int[] = new int[] { r.id.item_row };          // create array adapter , set display using our row         simplecursoradapter notes =             new simplecursoradapter(this, r.layout.item_row, itemcursor, from, to);         setlistadapter(notes);     }  } 

the code isn't near complete, goal combine functionality of android tutorial notepad touchlist.

my question is, doing wrong. there better way drag , drop lists.

thanks, chris swenor

you may building using java 1.5. in java 1.5, cannot use @override interface method definitions. adopted java 1.6.

however reason drop listener isn't getting triggered.

nothing leaps out @ me going wrong, other i'm not huge fan of system.out.print(). might try using breakpoints or log.w() or instead see if issue in logging.
