Question

我知道这个问题之前已被多次询问并且跟随它们而且我在很大程度上达到了标记，只剩下一个问题。我能够通过添加 textwatcher 来解决重复问题并使用 hashmap 来存储值，但剩下的问题是当我滚动回原始编辑文本时，原始编辑文本的值也消失了。我的意思是，如果我先输入EditText然后向下滚动，那么该值不会在任何地方重复，但我输入的EditText值也会消失。这是我的代码。

 @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        if (convertView == null) {
            holder = new ViewHolder();
            convertView = layoutInflater.inflate(R.layout.list_planmanobra_row, parent, false);
            holder.periodo_zafra = (TextView) convertView.findViewById(R.id.periodo_zafra);
            holder.CODIGO_FINCA = (TextView) convertView.findViewById(R.id.CODIGO_FINCA);
            //holder.NOMBRE_FINCA = (TextView) convertView.findViewById(R.id.NOMBRE_FINCA);
            holder.MES = (TextView) convertView.findViewById(R.id.MES);
            holder.CLAVE = (TextView) convertView.findViewById(R.id.CLAVE);
            holder.NOMBRE_CLAVE = (TextView) convertView.findViewById(R.id.NOMBRE_CLAVE);
            holder.CODIGO_ESTANDAR = (TextView) convertView.findViewById(R.id.CODIGO_ESTANDAR);
            holder.NOMBRE_ESTANDAR_MO = (TextView) convertView.findViewById(R.id.NOMBRE_ESTANDAR_MO);
            holder.CANTIDAD_ESTANDAR = (TextView) convertView.findViewById(R.id.CANTIDAD_ESTANDAR);
            holder.VALOR_UNITARIO = (TextView) convertView.findViewById(R.id.VALOR_UNITARIO);
            holder.VALOR_TOTAL = (TextView) convertView.findViewById(R.id.VALOR_TOTAL);
            holder.EJECUTA = (TextView) convertView.findViewById(R.id.EJECUTA);
            holder.btn_submit= (Button) convertView.findViewById(R.id.btn_submit);
            holder.btn_submit.setText("Enviar");
            holder.Cantidad= (EditText) convertView.findViewById(R.id.et_cantidad);
            holder.Cantidad_empleados= (EditText) convertView.findViewById(R.id.Cantidad_empleados);
            holder.checkbox= (CheckBox) convertView.findViewById(R.id.checkbox);

            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.periodo_zafra.setText(planmanobraBeanArrayList.get(position).getPERIODO_ZAFRA());
        holder.CODIGO_FINCA.setText(planmanobraBeanArrayList.get(position).getCODIGO_FINCA());
       // holder.NOMBRE_FINCA.setText(planiBeanArrayList.get(position).getNOMBRE_FINCA());
        holder.MES.setText(planmanobraBeanArrayList.get(position).getMES());
        holder.CLAVE.setText(planmanobraBeanArrayList.get(position).getCLAVE());
        holder.NOMBRE_CLAVE.setText(planmanobraBeanArrayList.get(position).getNOMBRE_CLAVE());
        holder.CODIGO_ESTANDAR.setText(planmanobraBeanArrayList.get(position).getCODIGO_ESTANDAR());
        holder.NOMBRE_ESTANDAR_MO.setText(planmanobraBeanArrayList.get(position).getNOMBRE_ESTANDAR_MO());
        holder.CANTIDAD_ESTANDAR.setText(planmanobraBeanArrayList.get(position).getCANTIDAD_ESTANDAR());
        holder.VALOR_UNITARIO.setText(planmanobraBeanArrayList.get(position).getVALOR_UNITARIO());
        holder.VALOR_TOTAL.setText(planmanobraBeanArrayList.get(position).getVALOR_TOTAL());
        holder.EJECUTA.setText(planmanobraBeanArrayList.get(position).getEJECUTA());
        holder.Cantidad.setText(editTextList.get(position));
        holder.Cantidad.addTextChangedListener(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) {
                editTextList.put(position,charSequence.toString());
            }

            @Override
            public void afterTextChanged(Editable editable) {

            }
        });
        holder.btn_submit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


            }
        });
        return convertView;
    }

Cantidad 是编辑文字

最后，我使用Focus Change Listener并在现有的arraylist中添加了一个参数。使用另一个列表或Hashmap对我没有用。正如 Yazan 所建议的那样，我将它添加到我的arraylist中并且现在正在工作。这是我现在的代码

 holder.Cantidad.setText(planmanobraBeanArrayList.get(position).getEditext());
        final ViewHolder finalHolder = holder;
        holder.Cantidad.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View view, boolean hasFocus) {
                if (!hasFocus)
                {
                    if (!finalHolder.Cantidad.getText().toString().equals(""))
                    {
                        planmanobraBeanArrayList.get(position).setEditext(finalHolder.Cantidad.getText().toString());
                    }else {
                        planmanobraBeanArrayList.get(position).setEditext("");
                    }
                }

            }
        });

感谢大家的帮助

listview中的EditText会重复
