核心代码1

viewHolder.etPlanCount.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) {
                }
     
                @Override
                public void afterTextChanged(Editable s) {
                    // 根据EditText的标签，更新数据源中的数据
                    int pos = (int) viewHolder.etPlanCount.getTag();
                    int count = s.toString().equals("") ? 0 : Integer.parseInt(s.toString());
                    mPlanScanProductInfoList.get(pos).setPlanCount(count);
     
                    onInputTextListener.afterChangedText(mPlanScanProductInfoList.get(pos).getProductNo(), count + "");
                }
            });

**注意事项: 编辑框设置tag要在holder为null的 判断里添加(好像不是,再试试)**

**实际操作:**

                holder = new ViewHolder(convertView);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }
                holder.adpItemGasolineNum.setTag(position);
            holder.adpItemNameTank.setText((position + 1) + "号油罐");
            holder.adpItemRg.check(StringUtils.equals(oiltanks.get(position).getOli_type(), "柴油") ? R.id.adp_item_rb_diesel : R.id.adp_item_rb_gasoline);
            oiltanks.get(position).setOli_type(holder.mainRbDiesel.isChecked() ? "柴油" : "汽油");
            holder.adpItemGasolineNum.setText(StringUtil.valueOf(oiltanks.get(position).getGuanCapacity()));
            holder.adpItemGasolineNum.addTextChangedListener(new MyTextWatcher(holder) {
                @Override
                public void afterTextChanged(Editable s, ViewHolder holder) {
                    int position=(Integer) holder.adpItemGasolineNum.getTag();
                    oiltanks.get(position).setGuanCapacity(s.toString().trim());
                }
            });
            return convertView;
