我正在尝试使用getString作为我的vIEwpager选项卡标题,所以我可以支持多语言,但每次我使用getString我得到错误片段没有附加到日志中的活动和应用程序强制关闭！

这是我的片段代码

public class RecipesFragment extends Fragment {VIEwPager pager;VIEwPagerAdapter adapter;SlIDingTabLayout tabs;CharSequence[] Titles = {(getResources().getString(R.string.invcraftingcardTitle)), (getResources().getString(R.string.wbcraftingcardTitle)), (getResources().getString(R.string.ovencraftingcardTitle)), (getResources().getString(R.string.paintTitle))};int Numboftabs = 4;@OverrIDepublic VIEw onCreateVIEw(LayoutInflater inflater, @Nullable VIEwGroup container, @Nullable Bundle savedInstanceState) {    VIEw v = inflater.inflate(R.layout.recipes_fragment, container, false);    return v;}@OverrIDepublic voID onActivityCreated(@Nullable Bundle savedInstanceState) {    super.onActivityCreated(savedInstanceState);    // Creating The VIEwPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.    adapter = new VIEwPagerAdapter(getActivity().getSupportFragmentManager(), Titles, Numboftabs);    // Assigning VIEwPager VIEw and setting the adapter    pager = (VIEwPager) getVIEw().findVIEwByID(R.ID.pager);    pager.setAdapter(adapter);    // Assiging the SlIDing Tab Layout VIEw    tabs = (SlIDingTabLayout) getVIEw().findVIEwByID(R.ID.tabs);    tabs.setdistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available wIDth    // Setting Custom color for the Scroll bar indicator of the Tab VIEw    tabs.setCustomTabcolorizer(new SlIDingTabLayout.Tabcolorizer() {        @OverrIDe        public int getIndicatorcolor(int position) {            return getResources().getcolor(R.color.tabsScrollcolor);        }    });    // Setting the VIEwPager For the SlIDingTabsLayout    tabs.setVIEwPager(pager);}

}

解决方法:

这是因为在调用onAttach之后可以使用变量Titles作为getResources

尝试在onAttach方法中初始化它,如下所示：

@OverrIDepublic voID onAttach(Activity activity) {    super.onAttach(activity);    Titles = {(getResources().getString(R.string.invcraftingcardTitle)), (getResources().getString(R.string.wbcraftingcardTitle)), (getResources().getString(R.string.ovencraftingcardTitle)), (getResources().getString(R.string.paintTitle))};}
