從列表視圖中的edittext中搜索項顯示錯誤的結果

Question

我有一個listview與自定義的行填充adapter.when我點擊任何行，它打開一個新的活動，我想要的。一切工作正常，但當我將搜索過濾器功能添加到此列表中，並且我在edittext中搜索listitem並獲取了正確的過濾器，但是當我單擊過濾器項目時，它不打開與其關聯的活動。它打開與其他listitems相關的其他活動，但不是我點擊one.it是非常奇怪的我。我不粘貼完整的代碼在這裏只附加所需的代碼。

這裏是我的代碼，我啓用了搜索功能在listview上編輯文本。

edtSearch.addTextChangedListener(new TextWatcher() { 

      public void onTextChanged(CharSequence s, int start, int before, 
        int count) { 
       adapter.getFilter().filter(s); 
       adapter.notifyDataSetChanged(); 

      } 

      public void beforeTextChanged(CharSequence s, int start, int count, 
        int after) { 

      } 

      public void afterTextChanged(Editable s) { 
      } 
     }); 
    } 

如果有關於相同的任何查詢，請給我評論，任何幫助將不勝感激。

這裏是我的完整代碼：

請參閱下面的代碼： -

@Override 
       public void onTextChanged(CharSequence s, int start, int before, int count) { 
        // TODO Auto-generated method stub 

        ArrayList<String> STOREID_SUB = new ArrayList<String>(); 
        ArrayList<String> STORE_NAME_SUB = new ArrayList<String>(); 
        ArrayList<String> PHOTO_SUB = new ArrayList<String>(); 
        ArrayList<String> PLACE_STATUS_SUB = new ArrayList<String>(); 
        final ArrayList<String> STORE_DESC_SUB = new ArrayList<String>(); 

        textlength = searchText.getText().length(); 

        for (int i = 0; i < STORE_NAME.size(); i++) 
        { 
         if (textlength <= STORE_NAME.get(i).length()) 
         { 
          if (searchText.getText().toString(). 
            equalsIgnoreCase((String) STORE_NAME.get(i).subSequence(0, textlength))) 
          { 
           STORE_NAME_SUB.add(STORE_NAME.get(i)); 
           STOREID_SUB.add(STOREID.get(i)); 
           PHOTO_SUB.add(PHOTO.get(i)); 
           STORE_DESC_SUB.add(STORE_DESC.get(i)); 
           PLACE_STATUS_SUB.add(PLACE_STATUS.get(i)); 


          } 
         } 
        } 

        adapter=new StoreSearchListAdapter(context, R.drawable.ic_launcher, R.drawable.ic_launcher, STORE_NAME_SUB, PHOTO_SUB,STORE_DESC_SUB,PLACE_STATUS_SUB); 
        singlePlaceChooserList.setAdapter(adapter); 



     } 

我在這裏創造onTextCahnged方法中一個新的數組列表，然後利用這些值來設置我的適配器。

您onItemClick更改爲：

@Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
      long arg3) { 
     // TODO Auto-generated method 

     if (((String)adapter.getItem(position)).equals("Admin Cost")) { 
      Intent int0 = new Intent(getApplicationContext(), Admincost.class); 
      startActivity(int0); 
     } 
      ......................... 

    } 

當您過濾列表，項目將重新排列和thier位置變化，使導航到下一個活動基於這一立場，而不是位置的值。
