也就是说，我们点击跳转到对应Activity的Fragment中，并且希望它能够返回参数，那么我们肯定是使用Fragment.startActivityForResult ;

在Fragment中存在startActivityForResult（）以及onActivityResult（）方法，但是呢，没有setResult（）方法，用于设置返回的intent，这样我们就需要通过调用getActivity().setResult(ListTitleFragment.REQUEST_DETAIL, intent);。

详细代码：

ListTitleFragment

public class ListTitleFragment extends ListFragment
{

?public static final int REQUEST_DETAIL = 0x110;
?private List mTitles = Arrays.asList("Hello", "World", "Android");
?private int mCurrentPos ;
?private ArrayAdapter mAdapter ;

?
?@Override
?public void onActivityCreated(Bundle savedInstanceState)
?{
? super.onActivityCreated(savedInstanceState);
? setListAdapter(mAdapter = new ArrayAdapter(getActivity(), android.R.layout.simple_list_item_1, mTitles));
?}
?
?@Override
?public void onListItemClick(ListView l, View v, int position, long id)
?{
? mCurrentPos = position ;
? Intent intent = new Intent(getActivity(),ContentActivity.class);
? intent.putExtra(ContentFragment.ARGUMENT, mTitles.get(position));
? startActivityForResult(intent, REQUEST_DETAIL);
?}

?
?@Override
?public void onActivityResult(int requestCode, int resultCode, Intent data)
?{
? Log.e("TAG", "onActivityResult");
? super.onActivityResult(requestCode, resultCode, data);
? if(requestCode == REQUEST_DETAIL)
? {
? ?mTitles.set(mCurrentPos, mTitles.get(mCurrentPos)+" -- "+data.getStringExtra(ContentFragment.RESPONSE));
? ?mAdapter.notifyDataSetChanged();
? }
?}
}

ContentFragment

public class ContentFragment extends Fragment
{

?private String mArgument;
?public static final String ARGUMENT = "argument";
?public static final String RESPONSE = "response";

?@Override
?public void onCreate(Bundle savedInstanceState)
?{
? super.onCreate(savedInstanceState);
? Bundle bundle = getArguments();
? if (bundle != null)
? {
? ?mArgument = bundle.getString(ARGUMENT);
? ?Intent intent = new Intent();
? ?intent.putExtra(RESPONSE, "good");
? ?getActivity().setResult(ListTitleFragment.REQUEST_DETAIL, intent);
? }

?}

?public static ContentFragment newInstance(String argument)
?{
? Bundle bundle = new Bundle();
? bundle.putString(ARGUMENT, argument);
? ContentFragment contentFragment = new ContentFragment();
? contentFragment.setArguments(bundle);
? return contentFragment;
?}

?@Override
?public View onCreateView(LayoutInflater inflater, ViewGroup container,
? ?Bundle savedInstanceState)
?{
? Random random = new Random();
? TextView tv = new TextView(getActivity());
? tv.setText(mArgument);
? tv.setGravity(Gravity.CENTER);
? tv.setBackgroundColor(Color.argb(random.nextInt(100),
? ? random.nextInt(255), random.nextInt(255), random.nextInt(255)));
? return tv;
?}
}

贴出了两个Fragment的代码，可以看到我们在ListTitleFragment.onListItemClick，使用startActivityForResult（）跳转到目标Activity，在目标Activity的Fragment（ContentFragment）中获取参数，然后调用getActivity().setResult(ListTitleFragment.REQUEST_DETAIL, intent);进行设置返回的数据；最后在ListTitleFragment.onActivityResult（）拿到返回的数据进行回显；
为大家以后在遇到类似问题时，提供了解决方案；也说明了一个问题：fragment能够从Activity中接收返回结果，但是其自设无法产生返回结果，只有Activity拥有返回结果。

接下来我要贴一下，这两个Fragment的宿主Activity:

ListTitleActivity

public class ListTitleActivity extends FragmentActivity
{

?private ListTitleFragment mListFragment;
