从列表视图中获取选定的对象

Question

I will find a way to get a selected item in my list view and then to cast in my object type, but i get an error i think is to big to see whats is wrong. Can you help me ?

My code :

mListMenu = (ListView) findViewById(R.id.listView_tracks);
        mListMenu.setAdapter(new TracksListAdapter(this, TrackManager.getAllTrackFromTel(new DataBaseHelper(this))));
        mListMenu.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapter, View arg1,
                    int position, long arg3) {
                    Track selectedItem = (Track) adapter.getAdapter().getItem(position);
                    Intent intent = new Intent();
                     Bundle bundle = new Bundle();
                     bundle.putLong("trackselected",selectedItem.getTrackid());
                    intent.putExtras(bundle);                   
                   //Envoi du resultat à l'origine
                    setResult(RESULT_OK, intent);
                    finish();


            }

        });

I get this error :

谢谢FD_，当我说太大而看不到问题时，这是我的方法（getItem）返回了错误的项目（复制粘贴太快）。
