onActivityResult 解耦 不需要一层一层的写

public abstract class AbsShareMessageTemplates implements IShareMessageTemplates {
    public final static String SHARE_EMPTY_FRAGMENT_TAG = "share_empty_fragment";

    public AbsShareMessageTemplates(Activity activity){
        if (activity instanceof FragmentActivity) {

            emptyFragment.setIShareMessageTemplates(this);
            FragmentTransaction fragmentTransaction = fm.beginTransaction();
            fragmentTransaction.add(emptyFragment, SHARE_EMPTY_FRAGMENT_TAG).commitAllowingStateLoss();
        }
    }

    public static class LifeCycleFragment extends Fragment{
        private IShareMessageTemplates iShareMessageTemplates;

        public void setIShareMessageTemplates(IShareMessageTemplates iShareMessageTemplates) {

        }

            }
        }
    }
}
