[移动开发]解决lietview列表item的edittext显示混乱问题

?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)

public class OutNoBillProductAdapter extends BaseAdapter {

    }
 
    @Override

        return mPlanScanProductInfoList != null ? mPlanScanProductInfoList.size() : 0;
    }
 
    @Override
    public Object getItem(int position) {
        return mPlanScanProductInfoList != null ? mPlanScanProductInfoList.get(position) : null;
    }
 
    @Override
    public long getItemId(int position) {
        return 0;
    }
 
    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder viewHolder;
        if (convertView != null) {
            viewHolder = (ViewHolder) convertView.getTag();
        } else {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.fragment_out_not_bill_item, null);
            viewHolder = new ViewHolder(convertView);
            convertView.setTag(viewHolder);
        }

        viewHolder.tvProductName.setText(mPlanScanProductInfoList.get(position).getProductName());
 
        // 在滑动的过程中，给每一个EditText设置其唯一的标签，动态的将item与position进行绑定，以便于监听的EditText文本内容改变，当内容改变时可以根据该标签去更新数据源中相应位置中数据。
        viewHolder.etPlanCount.setTag(position);
        viewHolder.etPlanCount.clearFocus();
 
        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

                mPlanScanProductInfoList.get(pos).setPlanCount(count);
 
                onInputTextListener.afterChangedText(mPlanScanProductInfoList.get(pos).getProductNo(), count + "");
            }
        });
 
        viewHolder.etPlanCount.setText(mPlanScanProductInfoList.get(position).getPlanCount() + "");

    final class ViewHolder {

    }
	
	 private abstract class MyTextWatcher implements TextWatcher{
        private ViewHolder mHolder;
        
        public MyTextWatcher(ViewHolder holder) {
            this.mHolder=holder;
        }
        
        @Override
        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                int arg3) {
        }
        @Override
        public void onTextChanged(CharSequence arg0, int arg1, int arg2,

            afterTextChanged(s, mHolder);

    }
}

实际操作:

ViewHolder holder = null;
        if (convertView == null) {
            convertView = UIUtils.inflate(R.layout.adp_item_tank);
            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;
