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;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_single_fragment);
FragmentManager fm = getSupportFragmentManager();
mListFragment = (ListTitleFragment) fm.findFragmentById(R.id.id_fragment_container);
if(mListFragment == null )
{
mListFragment = new ListTitleFragment();
fm.beginTransaction().add(R.id.id_fragment_container,mListFragment).commit();
}
}
}
