Listview edittext值滾動

我有一個列表視圖，每行都有一些edittext。在第一次加載時，我已將值分配給每個edittext並且是可編輯的。我可以編輯該edittext中的值。我的問題是，改變了那些行的位置後，即：滾動後，我得到的是edittexts中的初始值，而不是編輯值。過去6個小時我正在爲此工作。任何人都請幫助我。Listview edittext值滾動

這裏是我的適配器類

爲什麼ü採取單個陣列的每一個項目？ – Richa

，因爲您設置了來自array的編輯文本值。所以，當您更改edit-ext值時，您可以更新數組。 – Yugesh

您需要更新您的數組中s.toString()值。

Data_Openingstock.set(position, s.toString());

setNameTextChangeListener(Holder holder, int position); 

private void setNameTextChangeListener(final ViewHolder holder, final int position) { 
    holder.edittext_openingstock_baradmin.addTextChangedListener(new TextWatcher() { 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, int count) { 

    //do null check first before converting to string 

if(s.length() > 0) 
{ 
System.out.println("s.toString() "+s.toString()); 
Data_Openingstock.set(position, s.toString()); 
} 

     } 

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

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

您需要使用Viewholder類，每一次初始化的EditText而在列表視圖的getview充氣列表項的佈局。

if (convertView == null) { 

      holder = new ViewHolder(); 

      LayoutInflater vi = (LayoutInflater)  
      getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      convertView = vi.inflate(R.layout.element_in_game, null); 

      holder.scoreToUpdate = (EditText) convertView 
        .findViewById(R.id.elementUpdateScore); 


      convertView.setTag(holder); 

     } else { 

      holder = (ViewHolder) convertView.getTag(); 

     } 
     initScoresToUpdateEditTexts(holder.scoreToUpdate, hint); 
     holder.scoreToUpdate.setText(scoresToUpdate[tmp_position]); 
     holder.scoreToUpdate.addTextChangedListener(new TextWatcher() { 

       @Override 
       public void onTextChanged(CharSequence s, int start, 
         int before, int count) { 
        scoresToUpdate[tmp_position] = s.toString(); 
       } 

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

       } 

       @Override 
       public void afterTextChanged(Editable s) { 

       } 
      }); 

     return convertView; 
    }

我通過執行以下代碼解決了這個問題。放按照適配器類的getview方法代碼

viewHolder.invAmt.setTag(position);//set tag 

holder.edittext_openingstock_baradmin.addTextChangedListener(new TextWatcher() { 
    @Override 
    public void beforeTextChanged(CharSequence s, int start, int count, int after)   { 

    } 

@Override 
    public void onTextChanged(CharSequence s, int start, int before, int count) { 
     int pos = (Integer) holder.edittext_openingstock_baradmin.getTag(); 
     scoresToUpdate[pos] = s.toString(); 
    } 

    @Override 
    public void afterTextChanged(Editable s) { 

    } 
}); 
} else { 
     viewHolder = (ViewHolder) rowView.getTag(); 
}

嘗試it.100％的工作代碼
