我想从一个片段转到另一个片段。 首先,我传递了一些数据,然后我刷新了我的适配器,至少我是一个新的片段。
我的代码:
public class TestFragment extends Fragment {
private String horoscope_sign;
private Bundle bundle;
private FragmentItemHoroscopePage itemHoroscope;
private FragmentManager manager;
private FragmentTransaction transaction;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.test_fragment, container, false);
horoscope_sign = getArguments().getString("horoscope_sign");
bundle = new Bundle();
itemHoroscope = new FragmentItemHoroscopePage();
manager = getFragmentManager();
// Resetting adapter
if(FragmentItemHoroscopePage.getAdapter() != null) {
FragmentItemHoroscopePage.getAdapter().notifyDataSetChanged();
}
// Going to another fragment
transaction = manager.beginTransaction();
bundle.putString("horoscope_sign", horoscope_sign);
itemHoroscope.setArguments(bundle);
transaction.replace(R.id.mainContainer, itemHoroscope, "ItemHoroscope");
transaction.addToBackStack("ItemHoroscope");
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
transaction.commit();
return view;
}
}
我在检查适配器时遇到错误,我不知道为什么。有趣的是,如果我将整个代码推入OnButtonClick它正在工作。我该如何解决这个问题?

答案 0 :(得分:1)
我不知道什么是问题,但是我把try和catch子句放在一边,现在正在运行:
try {
if(FragmentItemHoroscopePage.getAdapter() != null) {
System.out.println("REFRESH");
FragmentItemHoroscopePage.getAdapter().notifyDataSetChanged();
}
} catch (Exception e) {
e.printStackTrace();
}
