Question

我有一个自定义列表视图适配器，其中包含一个textview和一个单选按钮，我用它来填充我的listview。现在一切正常，但我面临的问题是，当我点击任何listview行时，我无法选择radiobutton。我尝试了不同的代码，如

How to set radiobutton unchecked in adapter class

Android ListView with RadioButton/CheckBox in singleChoice mode and a custom row layout conditions on radiobuttons in custom listview 在互联网上，但他们没有帮助我。任何人都可以帮我解决这个问题吗？

这是我的适配器类：

public class Adapterclass extends BaseAdapter
{

private Context mContext;
private List<String> items;
public String selectedUrl = "";
private RadioButton mSelectedRB;
private int selected = -1;
private String title = "";

public Adapterclass(Context c, List<String> items)
{
    this.mContext = c;
    this.items = items;
}

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

@Override
public Object getItem(int position)
{
    return this.items.get(position);
}

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

@Override
public int getViewTypeCount() {
    //Count=Size of ArrayList.
    return this.items.size();
}

@Override
public int getItemViewType(int position) {

    return position;
}


@Override
public View getView(final int position, View child, ViewGroup parent)
{
    TextView Title;
    final RadioButton btnradio;
    boolean[] mStarStates = new boolean[0];

    LayoutInflater layoutInflater;
    if (child == null) {
        layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        child = layoutInflater.inflate(R.layout.list_cell, null);
    }

    Title = (TextView) child.findViewById(R.id.sound_title);
    btnradio = (RadioButton) child.findViewById(R.id.radioSelectButton);
    title = this.items.get(position);
    Title.setText(title);
    btnradio.setTag(title);

    btnradio.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view)
        {
            if(position != selected && mSelectedRB != null){
                mSelectedRB.setChecked(false);
            }

            selected = position;
            mSelectedRB = (RadioButton)view;
            selectedUrl = (String)view.getTag();
            //notifyDataSetInvalidated();
        }
    });

    if(selected != position){
        btnradio.setChecked(false);
    }else{
        btnradio.setChecked(true);
        if(btnradio != null && btnradio != mSelectedRB){
            mSelectedRB = btnradio;
        }
    }
    return child;
}
 }

我是否需要将radioGroup用于一个radiobutton。或者解决我想要做的事情。任何帮助将不胜感激：）
