ListFragment可以与ListView一起使用吗？

编辑：附件是自定义适配器的代码：

public class ListAdapterFeed  extends ArrayAdapter<String>
{
    Context mContext;

    public ListAdapterFeed(Context context, List<String> feedList){
        super(context, R.layout.fragment_news_feed, feedList);

        mContext = context;
    }

    @Override
    public View getView(int position, View contentView , ViewGroup parent)
    {
        View row = contentView;
        if (row == null){
            row = ((Activity)mContext).getLayoutInflater().inflate(R.layout.fragment_news_feed, null);
        }
        //  update your inner views value here
        return row;
    }
}

我现在在运行时得到的异常：

  

java.lang.ClassCastException：android.view.ContextThemeWrapper不能   被强制转换为android.app.Activity

我尝试使用ListFragment和ListView ... 但是我收到运行时错误告诉我：

我不想使用TextView，因为我想添加一个监听器，我想在整个过程中向视图中添加项目。

有什么想法吗？

1 个答案:

答案 0 :(得分：0)

 setListAdapter(new ArrayAdapter(getActivity(), R.layout.fragment_news_feed, rssFeed));

当崩溃日志显示ArrayAdapter期望列表项至少有一个TextView来更新rssFeed中的值。

您需要创建一个简单的自定义适配器，然后像这样覆盖getView（）

@Override
public View getView(int position, View contentView , ViewGroup parent)
{
    View row = contentView;
    if (row == null){
        row = mContext.getLayoutInflater().inflate(R.layout.fragment_news_feed, null);
    }
    //  update your inner views value here
    return row;
}

现在，您可以将自定义Adapter设置为ListFragment 

setAdapter(new CustomAdapter(context));
