android - Android-自定义Adapter <Class>不获取对象

我创建了一个自定义适配器，以将Itens发送到我的适配器类。

我的项目：

  public ItemAcompanhe(String dataPar, String cabecalhoPar, String descricaoPar, int imagePar){
    this.data = dataPar;
    this.cabecalho = cabecalhoPar;
    this.descricao = descricaoPar;
    this.image = imagePar;
}

我的适配器

 public AdapterAcompanheSantana(Context context, int resource, ArrayList<ItemAcompanhe> objects/*, String[] objects2*/) {
    //super(context, resource, objects);
    super(context, resource, objects);
}

我在iten上设置的适配器：

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v=((Activity)getContext()).getLayoutInflater().inflate(R.layout.item_list_acompanhe,null);

    ItemAcompanhe holder = null;
    holder = new ItemAcompanhe(jsonItemAcompanhe);

    // ImageView     item_acompanhe_btn_topo
    ImageView img = (ImageView) v.findViewById(R.id.item_acompanhe_btn_topo);
    img.setBackgroundResource(image[position]);

    // TextView      item_acompanhe_txt_cabecalho   CABECALHO DESCRICAO
    TextView textViewTituloAgendaFragItem = (TextView) v.findViewById(R.id.item_acompanhe_txt_cabecalho);
    textViewTituloAgendaFragItem.setText(listaDeCabecalhos[position]);

    // TextView      item_acompanhe_txt_data
    TextView textViewDatasAgendaFragItem = (TextView) v.findViewById(R.id.item_acompanhe_txt_data);
    textViewDatasAgendaFragItem.setText(listaDeDatas[position]);

    // TextView      item_acompanhe_txt_conteudo
    TextView textViewDescricaoAgendaFragItem = (TextView) v.findViewById(R.id.item_acompanhe_txt_conteudo);
    textViewDescricaoAgendaFragItem.setText(listaDeDescricao[position]);

    Typeface font = Typeface.createFromAsset(getContext().getAssets(), "fonts/OpenSans-Regular.ttf");
    textViewDescricaoAgendaFragItem.setTypeface(font);



    return v;
}

我无法从设置为Adapter中参数的列表中获得任何项目。
有人知道我该如何解决吗？

最佳答案

这个

ItemAcompanhe holder = null;
holder = new ItemAcompanhe(jsonItemAcompanhe);

应该替换为

ItemAcompanhe holder = getItem(position);

它将从数据集中获取一个项目（在您的情况下，由超类处理）。我建议您避免每次调用getView时都要为新的convertView充气，但前提是convertView为null

 if (convertView == null) {
    convertView = ((Activity)getContext()).getLayoutInflater().inflate(R.layout.item_list_acompanhe,null);
 }

并返回convertView
