android - Text values has order changes when scroll the listview in android

Question

When I click to edit my EditText in my list-view, the order of items change. I think the problem is on adapter, but I don't know how to fix it.

Ex.: The last item goes to second position.

Adapter:

public class adapterAvaliacao extends BaseAdapter {

private LayoutInflater mInflater;
private List<Nota> itens;
DecimalFormat formatoNota = new DecimalFormat("#0.00");

public adapterAvaliacao(Context context, List<Nota> itens) {
    this.itens = itens;
    mInflater = LayoutInflater.from(context);
}

@Override
public int getCount() {
    return itens.size();
}

@Override
public Nota getItem(int position) {
    return itens.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@SuppressLint({ "ViewHolder", "InflateParams" }) @Override
public View getView(int position, View convertView, ViewGroup parent) {

    if (convertView == null) {
        Nota item = itens.get(position);

        convertView = mInflater.inflate(R.layout.avaliacao_adapter, null);
        ((TextView) convertView.findViewById(R.id.lbl_nomeAtividade)).setText(item.getTitulo());
        if (item.isLancada()) {
            ((EditText) convertView.findViewById(R.id.txt_notaPostada)).setText(String.valueOf(formatoNota.format(item.getNota() * 10 / item.getPeso())).replace(",", "."));
        }
    } else {
        convertView.setTag(convertView.getTag());
        }
    return convertView;
}

是的，这是 listView 的正常行为，因此可以根据需要将值存储在 arraylist 或模型中，以便在滚动时进行设置。

由于列表视图项目的回收，您必须这样做。

你的 setText 代码行应该写在 else 部分之后：

if (convertView == null) {
//your stuffs like find edit text

    }
    else {
            convertView.setTag(convertView.getTag());
         }
    editText.setText("hello world");
