Question

Я использую ArrayAdapter Когда я удаляю первый элемент из Listview.Its delete perfect.But Когда я удаляю второй элемент из списка. Его не совсем удалить. как я могу это сделать?

адаптер кодирования

import android.widget.ArrayAdapter; 
@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    // final CartBean beans = getItem(position); 

    View view = convertView; 
    final ViewHolder viewHolder; 

    if (convertView == null) { 
     LayoutInflater inflater = (LayoutInflater) getContext() 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     view = inflater.inflate(R.layout.list_cart_row, parent, false); 

     viewHolder = new ViewHolder(); 

     viewHolder.row_price = (TextView) view.findViewById(R.id.row_price); 
     viewHolder.et_quantity = (EditText) view.findViewById(R.id.cart_quantity); 
     viewHolder.row_item_name = (TextView) view.findViewById(R.id.row_item_name); 
     viewHolder.deleteButton = (ImageView) view.findViewById(R.id.iv_delete); 
     // viewHolder.rastaurantoffer = (ImageView) view.findViewById(R.id.rastaurantname2); 


     view.setTag(viewHolder); 
    } else { 
     viewHolder = (ViewHolder) convertView.getTag(); 
    } 

    if (viewHolder.textWatcher != null) 
     viewHolder.et_quantity.removeTextChangedListener(viewHolder.textWatcher); 
    final CartBean bean = getItem(position); 
    viewHolder.textWatcher = new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { 

     } 

     @Override 
     public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) { 

      if (charSequence.length()>0) { 
       viewHolder.row_price.setText(String.valueOf(df.format(Double.parseDouble(bean.getTotal_price()) * Integer.parseInt(charSequence.toString())))); 
       AppConstants.cartBeanArrayList.get(position).setQuantity(Integer.parseInt(charSequence.toString())); 

      } 
     } 

     @Override 
     public void afterTextChanged(Editable editable) { 
      Double totalPrice=0.0; 
      for (int i=0;i<AppConstants.cartBeanArrayList.size();i++) 
      { 
       totalPrice=totalPrice+(Double.parseDouble(AppConstants.cartBeanArrayList.get(i).getTotal_price()) * AppConstants.cartBeanArrayList.get(i).getQuantity()); 
       Log.i("total_price12356",""+total_price); 
      } 
      ActivityCart.tv_sub_total.setText("£. "+String.valueOf(df.format(totalPrice))); 
     } 
    }; 
     viewHolder.row_price.setText("£."+String.valueOf(df.format(Double.parseDouble(cartBeans.get(position).getTotal_price()) * cartBeans.get(position).getQuantity()))); 
     viewHolder.et_quantity.setText(String.valueOf(cartBeans.get(position).getQuantity())); 
     viewHolder.row_item_name.setText(cartBeans.get(position).getItem_name()); 
     viewHolder.et_quantity.addTextChangedListener(viewHolder.textWatcher); 
     if(isDeleteRequired){ 
     viewHolder.deleteButton.setVisibility(View.VISIBLE); 
     viewHolder.et_quantity.setInputType(InputType.TYPE_CLASS_NUMBER); 
     viewHolder.et_quantity.setFocusableInTouchMode(true); 
     viewHolder.et_quantity.setCursorVisible(true); 
     viewHolder.deleteButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 

       AppConstants.cartBeanArrayList.remove(position); 
       notifyDataSetChanged(); 

       for (int i = 0; i < AppConstants.cartBeanArrayList.size(); i++) { 
        // String price = AppConstants.cartBeanArrayList.get(i).getTotal_price().substring(3, AppConstants.cartBeanArrayList.get(i).getTotal_price().length()); 
        // Log.i("total_price123",""+price); 
        total_price = total_price + ActivityCart.getTotal(i); 
        Log.i("total_price123",""+total_price); 
        Log.i("total_price1237",""+AppConstants.cartBeanArrayList.size()); 
       //  AppConstants.cartBeanArrayList.clear(); 

       } 

       Log.i("total_price1234",""+total_price); 
       ActivityCart.tv_sub_total.setText("£. "+String.valueOf(total_price)); 
       if (AppConstants.cartBeanArrayList.size()==0) 
       { 
        ActivityCart.tv_sub_total.setText("£.0.00"); 
       } 
       // AppConstants.addressBeanArrayList.setText(String.valueOf(total_price)); 
      } 
     }); 

    }else{ 
     viewHolder.deleteButton.setVisibility(View.GONE); 
    } 

    return view; 
} 

class ViewHolder { 

    TextView row_item_name; 
    TextView row_price; 
    EditText et_quantity; 
    ImageView deleteButton; 
    public TextWatcher textWatcher; 

} 

public void setIsDeleteRequired(boolean isDeleteRequire){ 
    isDeleteRequired = isDeleteRequire; 
} 
} 

И getTotal() Метод кодирования является:

public static Double getTotal(int i) { 
    total =(Double.parseDouble(AppConstants.cartBeanArrayList.get(i).getTotal_price()) * AppConstants.cartBeanArrayList.get(i).getQuantity()); 
    Log.i("totalsunder", "" +total); 
    return total; 
} 

Answer 1

Да, я получил ответ сам.

Вот мой код

 viewHolder.deleteButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 

       AppConstants.cartBeanArrayList.remove(position); 


       for (int i = 0; i < AppConstants.cartBeanArrayList.size(); i++) { 


        total_price = total_price + ActivityCart.getTotal(i); 



       } 


       ActivityCart.tv_sub_total.setText("£. "+String.valueOf(total_price)); 
total_price =0.0; 
      notifyDataSetChanged(); 

      } 
     }); 

Answer 2

delete.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       // TODO Auto-generated method stub 

//removing from database 
       int i =impl_cart.deleteRow(data_cart.get(position).get_id()); 
//removing from adapter 
       data_cart.remove(position); 
       notifyDataSetChanged(); 


      } 
     });
