Question

基本上我需要的是更新你点击按钮的listview项的值。

@Override
public View getView(int position, View convertView, final ViewGroup parent) {
    ViewHolder holder = null;
    RowItem rowItem = getItem(position);
    LayoutInflater mInflater = (LayoutInflater) context
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.lista_validacion_multiple, null);
        holder = new ViewHolder();
        /*holder.row1 = (TableRow)convertView.findViewById(R.id.tableRow2);
        holder.row2 = (TableRow)convertView.findViewById(R.id.tableRow3);*/
        holder.txtNombre = (TextView)convertView.findViewById(R.id.txtNombre);
        holder.txtAsiento = (TextView)convertView.findViewById(R.id.txtAsiento);
        holder.txtTicket = (TextView)convertView.findViewById(R.id.txtTicket);
        holder.txtNumero = (TextView)convertView.findViewById(R.id.txtNumero);
        holder.btn = (Button)convertView.findViewById(R.id.button1);
        //holder.imageView = (ImageView)convertView.findViewById(R.id.icon1);
        convertView.setTag(holder);
    } else
        holder = (ViewHolder) convertView.getTag();

    holder.txtNombre.setText("Nombre :"+rowItem.getNombre());
    holder.txtTicket.setText("Ticket :"+rowItem.getTicket());
    if (!rowItem.getAsiento().equals("") && !rowItem.getAsiento().equals("null") && rowItem.getAsiento() != null) {
        holder.txtAsiento.setText("Asiento :"+rowItem.getAsiento());
    }
    if (!rowItem.getNumero().equals("") && !rowItem.getNumero().equals("null") && rowItem.getNumero() != null) {
        holder.txtNumero.setText("Número :"+rowItem.getNumero());
    }
    if(rowItem.getValidado()==1){
        holder.btn.setBackgroundResource(R.drawable.icon_big_alert);
        holder.btn.setText("");
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams((int)LayoutParams.WRAP_CONTENT, (int)LayoutParams.WRAP_CONTENT);
        params.width = 50;
        params.height = 50;
        params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        holder.btn.setLayoutParams(params);
    }else{
        holder.btn.setTag(position);
        holder.btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                int position=(Integer)v.getTag();
                RowItem item_click = getItem(position);
                Connection cn = new Connection();
                SessionManager manager = new SessionManager();
                if(cn.isNetworkAvailable(parent.getContext())){

                }else{
                    BaseDeDatos nueva = new BaseDeDatos();
                }
            }
        });

    }
    return convertView;
}

我考虑过调用holder.btn，但这不起作用，因为它不在同一个上下文中，有一些方法可以编辑这个项目吗？

Answer 1

试试这个

 int position= Integer.parseInt(v.getTag());

希望这项工作

单击按钮后更新列表视图中的项目
