在这里你得到了片段的onCreate方法来加载所有内容:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
bundle = this.getArguments();
debts = bundle.getParcelableArrayList("list");
adapter = new CardAdapter(getActivity(), android.R.color.holo_blue_dark);
for (int i=0; i<debts.size();++i) {
Debt d = debts.get(i);
Card card = new Card(d.getSecondUser(),d.getSubject());
adapter.add(card);
}
}
这里是onActivityCreated方法,我为列表设置了适配器:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
CardListView list = (CardListView) getView().findViewById(R.id.newCard);
list.setCardTheme(CardTheme.Light);
list.setAdapter(adapter);
}
如果我使用已经加载的卡的ArrayList,它可以工作,但不是这样。 我几乎尝试了一切......非常感谢你。
更新:即使我尝试了你给我的解决方案,它仍在发生,我的代码现在:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
bundle = this.getArguments();
debts = bundle.getParcelableArrayList("list");
adapter = new CardAdapter(getActivity(), android.R.color.holo_blue_dark);
for (int i=0; i<debts.size();++i) {
Debt d = debts.get(i);
Card card = new Card(d.getSecondUser(),d.getSubject());
adapter.add(card);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_debts, container,
false);
CardListView list = (CardListView) rootView.findViewById(R.id.newCard);
list.setCardTheme(CardTheme.Light);
list.setAdapter(adapter);
return rootView;
}
答案 0 :(得分:0)
您应该在onCreateView()方法中初始化cardListView。在onActivityCreated()方法之前调用onCreateView()。 onCreateView()应该是片段视图初始化时的点。
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//use your layout file instead of R.layout.fragment_main
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
CardListView list = rootView.findViewById(R.id.newCard);
list.setCardTheme(CardTheme.Light);
list.setAdapter(adapter);
}
