ListView控件setOnItemClickListener在ListFragment不工作

问题描述

我正在开发一个使用动作条的标签，以显示通过ListFragment选项列表的应用程序。该列表（和ListFragment）显示没有问题，但ListView的setOnItemClickListener似乎并不工作，在列表中的项目被点击时没有任何反应。这里的code为ListFragment类：

I am developing an app that uses ActionBar tabs to display a list of options through ListFragment. The list (and ListFragment) display without a problem, but the ListView's setOnItemClickListener doesn't seems to work, as nothing happens when an item in the list is clicked. Here's the code for the ListFragment class:

package XXX.XXX;

public class AboutFrag extends SherlockListFragment
{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                    Bundle savedInstanceState)
    {
            View view = inflater.inflate(R.layout.aboutfrag, container, false);

            ListView lv = (ListView) view.findViewById(android.R.id.list);

            String[] items = new String[] {"About 1", "About 2", "About 3"};

            lv.setAdapter(new ArrayAdapter<String>(getActivity(), R.layout.list_item, items));

            lv.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {

                    switch (position)
                    {
                        case 0:
                          Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com"));
                          startActivityForResult(browserIntent, 0);
                          break;

                        case 1:
                          Intent browserIntent2 = new Intent(Intent.ACTION_VIEW, Uri.parse("http://wikipedia.org"));
                            startActivityForResult(browserIntent2, 0);
                            break;

                        case 2:
                          Intent browserIntent3 = new Intent(Intent.ACTION_VIEW, Uri.parse("http:/android.com");
                            startActivityForResult(browserIntent3, 0);
                            break;
                    }
                }
              });

            return view;
    }
}

我猜想这是行不通的，因为类返回视图对象，所以FragmentActivity不能运行监听code，所以没有人知道如何使这项工作？顺便说一句，我使用ActionBarSherlock。在此先感谢！

I'm assuming it does not work because the class returns the view object, so the FragmentActivity can't run the listener code, so does anyone know how to make this work? By the way, I am using ActionBarSherlock. Thanks in advance!!!

推荐答案

您还可以覆盖从SherlockListFragment继承onListItemClick方法。

You can also override a onListItemClick method that is inherited from the SherlockListFragment.

如下：

@Override
public void onListItemClick(ListView l, View v, int position, long id)
{
      super.onListItemClick(l, v, position, id);

   switch (position)
                    {
                        case 0:
                          Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com"));
                          startActivityForResult(browserIntent, 0);
                          break;

                        case 1:
                          Intent browserIntent2 = new Intent(Intent.ACTION_VIEW, Uri.parse("http://wikipedia.org"));
                            startActivityForResult(browserIntent2, 0);
                            break;

                        case 2:
                          Intent browserIntent3 = new Intent(Intent.ACTION_VIEW, Uri.parse("http:/android.com");
                            startActivityForResult(browserIntent3, 0);
                            break;
                    }

}
