Question

我在每行都有一个带有EditText的Listview。我需要获得焦点行的ID。在我的代码中，holder.valor.getId（）;总是返回相同的ID。我不明白为什么！

在其他活动中，我想要扩展edittext并从操作栏按钮更改键盘类型。

这是我的代码：

public View getView(final int position, View convertView, ViewGroup parent) {
    final ViewHolder holder;
    final String marca;
    final String producto;
    try {
        if (convertView == null) {
            holder = new ViewHolder();
            LayoutInflater vi = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = vi.inflate(R.layout.row_lista_form, null);

            holder.item = (TextView) convertView.findViewById(R.id.item);
            holder.valor = (EditText) convertView.findViewById(R.id.valor);
            holder.valor.setInputType(InputType.TYPE_CLASS_PHONE);
            holder.imgCam = (ImageView) convertView.findViewById(R.id.cambutton);

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

        marca = getlForm().get(position).getMarca();
        producto = getlForm().get(position).getProducto();
        final int proyectoproducto = getlForm().get(position).getProyectoProductoId();
        String valor = getlForm().get(position).getCantidad();
        if (valor == null || valor.equals("null"))
            valor = "";
        holder.item.setText(marca + "\n" + producto);
        holder.valor.setText(valor);

        // Listener : If focus lost, we insert value in db
        holder.valor.setOnFocusChangeListener(new OnFocusChangeListener() {

            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus) {
                    // update row
                    Formulario f = getlForm().get(position);
                    EditText et = (EditText) v;
                    f.setCantidad(et.getText().toString());
                    f.setSync(0);
                    FormHandler fh = new FormHandler(ctx);
                    boolean existForm = fh.existForm(f);
                    if (!existForm)
                        fh.addForm(f);
                    else
                        fh.updateForm(f);

                }else{
                    // We have the focus, we send the id in the prefs,
                    // to send it the change keyboard function
                    int editTextId = holder.valor.getId();
                    prefs.edit().putInt("metricaEtId", editTextId).commit();
                }

            }
        });

    } catch (Exception e) {
        e.printStackTrace();
    }
    return convertView;
}

使用

v.getId();

在

onFocusChange(View v,....

View.getId（）始终在listview中使用holder模式返回相同的id
