带有 Radiobutton 的自定义 Listview，选择了几个 .. Android

Question

我有一个自定义列表视图，如下图所示。但是要选择第一个单选按钮，也会选择滚动结束后的单选按钮，根据 eh read 那是通过使用android回收视图。我尝试了几种解决方案，但都没有成功..如果有人也一样，想看看我是否可以提供帮助..这是我的 Apadapter 的代码，你看看..干杯...！！

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

    View rowView = convertView;

    if (rowView == null) {

        LayoutInflater inflater = context.getLayoutInflater();
        rowView = inflater.inflate(R.layout.list_single, null, true);
        ViewHolder viewHolder = new ViewHolder();

        viewHolder.pregunta = (TextView) rowView.findViewById(R.id.texto_pregunta);
        viewHolder.rdo1 = (RadioButton) rowView.findViewById(R.id.radio0);

        rowView.setTag(viewHolder);
    }

    ViewHolder holder = (ViewHolder) rowView.getTag();
    holder.pregunta.setText((position + 1) + ".- " + desc.get(position));
    holder.rdo1.setText(minimo.get(position));
    return rowView;
}

public static class ViewHolder {
    public TextView pregunta;
    public RadioButton rdo1;
    public RadioButton rdo2;
    public RadioButton rdo3;
}

感谢回复的人。阅读我收到的回复，我找到了解决方案。

如果他们和我有同样的问题，我会让我的适配器继续使用它...

public class CustomList extends ArrayAdapter<String> {

private final Activity context;
private final ArrayList<String> minimo;
private final ArrayList<String> maximo;

private ArrayList<Boolean> status = new ArrayList<Boolean>();

public CustomList(Activity context, ArrayList<String> min, ArrayList<String> max) {
    super(context, R.layout.list_single, min);
    this.context = context;
    this.minimo = min;
    this.maximo = max;

    //initialize all with false
    for (int i = 0; i < minimo.size(); i++) {
        status.add(false);
    }
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

    View rowView = convertView;

    LayoutInflater inflater = context.getLayoutInflater();
    rowView = inflater.inflate(R.layout.list_single, null, true);
    ViewHolder viewHolder = new ViewHolder();

    viewHolder.pregunta = (TextView) rowView.findViewById(R.id.texto_pregunta);
    viewHolder.rdo1 = (RadioButton) rowView.findViewById(R.id.radio0);
    rowView.setTag(viewHolder);

    ViewHolder holder = (ViewHolder) rowView.getTag();
    holder.pregunta.setText("Some Text Answer");
    holder.rdo1.setText(minimo.get(position));
    holder.rdo1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

            //change status when clicked
            status.set(position, isChecked);

            //verified status all radiobuttons
            for (int i = 0; i < status.size(); i++) {
                Log.v("Log", "" + status.get(i));
            }
        }
    });
    holder.rdo1.setChecked(status.get(position));
    return rowView;
}

public static class ViewHolder {
    public TextView pregunta;
    public RadioButton rdo1;
    public RadioButton rdo2;
    public RadioButton rdo3;
}

}

您可以将检查的值存储在模型中。我看到你使用列表来存储一些数据，所以你也可以创建一个选中的列表，然后在getView方法中使用它：

private ArrayList<Boolean> checked;

holder.rdo1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            checked.set(position, isChecked);
        }
});
holder.rdo1.setChecked(checked.get(position));
