Wie kann ich ursprüngliche Aktivitäten öffnen, indem ich nach dem Filtern der Listenansicht auf ein Listenansichtselement klicke?

Question

Mein Code funktioniert gut, wenn es um das Anklicken von Elementen geht. Aber das Problem tritt auf, wenn ich versuche, nach dem Filtern von Listview Aktivitäten zu öffnen. Es öffnet immer die Aktivität 1.

Hier ist mein Quellcode.

navigate.java

public class navigate extends Activity { 

    // Declare Variables 
    ListView list; 
    ListViewAdapter adapter; 
    EditText editsearch; 
    String[] rank; 
    String[] names; 

    int[] flag; 
    ArrayList<Object> arraylist = new ArrayList<Object>(); 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.listview_main); 

     // Generate sample data 
     rank = new String[] { "1", "2", "3", "4", "5","6","7","8","9","10","11"}; 

     names = new String[] { "Animal Bite", "Asthma Attack", "Choking","CPR","Black eye", 
       "Drowning", "Fracture","Heart Attack","Insect Bite","Poisoning","Spinal Injury",}; 


     flag = new int[] { R.drawable.animal, 
       R.drawable.asthma, R.drawable.choke, R.drawable.cpricon, 
       R.drawable.blckeye,R.drawable.drown,R.drawable.fracture,R.drawable.hrtattck,R.drawable.insect,R.drawable.poison,R.drawable.spinal }; 

     // Locate the ListView in listview_main.xml 
     list = (ListView) findViewById(R.id.listview); 

     for (int i = 0; i < rank.length; i++) 
     { 
      Object wp = new Object(rank[i], names[i], flag[i]); 
      // Binds all strings into an array 
      arraylist.add(wp); 
     } 

     // Pass results to ListViewAdapter Class 
     adapter = new ListViewAdapter(this, arraylist); 

     // Binds the Adapter to the ListView 
     list.setAdapter(adapter); 

     // Locate the EditText in listview_main.xml 
     editsearch = (EditText) findViewById(R.id.search); 

     // Capture Text in EditText 
     editsearch.addTextChangedListener(new TextWatcher() { 

      @Override 
      public void afterTextChanged(Editable arg0) { 
       // TODO Auto-generated method stub 
       String text = editsearch.getText().toString().toLowerCase(Locale.getDefault()); 
       adapter.filter(text); 
      } 

      @Override 
      public void beforeTextChanged(CharSequence arg0, int arg1, 
        int arg2, int arg3) { 
       // TODO Auto-generated method stub 
      } 

      @Override 
      public void onTextChanged(CharSequence arg0, int arg1, int arg2, 
        int arg3) { 
       // TODO Auto-generated method stub 
      } 
     }); 
     list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(final AdapterView<?> listView, View view, 
            final int position, long id) { 
       switch ((int) adapter.getItemId(position)) { 
        case 0: 
         Intent newActivity = new Intent(navigate.this, animalbite.class); 
         startActivity(newActivity); 
         break; 
        case 1:Intent newActivity1 = new Intent(navigate.this, asthmaattack.class); 
         startActivity(newActivity1); 
         break; 
        case 2:Intent newActivity2 = new Intent(navigate.this, animalbite.class); 
         startActivity(newActivity2); 
         break;} 

      } 
     }); 
    }

     holder.name.setText(objectList.get(position).getCountry()); 
     ; 
     // Set the results into ImageView

       .getFlag());

Wie kann ich verschiedene Aktivitäten öffnen, während auf Listenansicht Artikel klicken, nachdem ich sie filtern.

Dies ist der Beispielcode, den ich verwendet habe. Obwohl es nicht die Funktionalität bietet, um originale Aktivitäten durch Absicht zu öffnen, nur einige gefälschte Aktivitäten, also versuche ich das zu ändern. http://www.androidbegin.com/tutorial/android-search-filter-listview-images-and-texts-tutorial/

Ich denke, Ihr Adapter Problem hat, das unter Beispielcode meiner Anwendung von Filterable verlängert und funktionieren

public class AdapterContacts extends BaseAdapter implements Filterable { 

    private LayoutInflater inflater; 
    private Context context; 
    private List<ContactLists> categoryArrayList; 
    private final ArrayList<ContactLists> originalList = new ArrayList<ContactLists>(); 
    private NameFilter filter; 

    public AdapterContacts(ArrayList<ContactLists> array) { 
     categoryArrayList = array; 
    } 

    public AdapterContacts(Context context, List<ContactLists> array) { 
     this.context = context; 
     inflater = LayoutInflater.from(this.context); 
     categoryArrayList = array; 
     originalList.addAll(array); 
    } 

    @Override 
    public int getCount() { 
     return categoryArrayList.size(); 
    } 

    @Override 
    public ContactLists getItem(int position) { 
     return categoryArrayList.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return 0; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ViewHolder mViewHolder; 

     if (convertView == null) { 
      convertView = inflater.inflate(R.layout.layout_contacts_list_item, null); 
      mViewHolder = new ViewHolder(convertView); 
      convertView.setTag(mViewHolder); 
     } else { 
      mViewHolder = (ViewHolder) convertView.getTag(); 
     } 

     ContactLists item = getItem(position); 
     mViewHolder.fillItems(this, item, position); 

     return convertView;
