Question

在Developer Console中，我可以看到来自不同设备的多个崩溃报告。

堆栈跟踪：

  at android.support.v4.app.Fragment.performCreateView(Fragment.java:2192)

我的代码：

// AbsTabFragment
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(mLayoutId, container, false); // line 46
        View prevTab = view.findViewById(R.id.prev_tab);
        View nextTab = view.findViewById(R.id.next_tab);

        OnPrevNextClickListener clickListener = new OnPrevNextClickListener();

        if (prevTab != null) {
            prevTab.setOnClickListener(clickListener);
        }

        if (nextTab != null) {
            nextTab.setOnClickListener(clickListener);
        }

        return view;
    }

    protected void setData(int layoutId, OnTabNaviListener listener) {
        mLayoutId = layoutId;
        mTabNaviCallback = listener;
    }

和MapTabFragment：

public class MapTabFragment extends AbsTabFragment implements OnMapReadyCallback {
    public MapTabFragment() {
        // Required empty public constructor
    }

    public static MapTabFragment getInstance(OnTabNaviListener listener, OnMapFragmentListener callback) {
        MapTabFragment fragment = new MapTabFragment();
        fragment.setData(R.layout.fragment_map_tab, listener);
        fragment.mCallback = callback;
        return fragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        Log.v(TAG, "onCreateView: ");
        View view = super.onCreateView(inflater, container, savedInstanceState); // line 122

        mDistance = (DataCard) view.findViewById(R.id.distance);
        mAverageSpeed = (DataCard) view.findViewById(R.id.average_speed);
        mActivityTime = (DataCard) view.findViewById(R.id.activity_time);
        mTotalTime = (DataCard) view.findViewById(R.id.total_time);
        mAntenna = (Antenna) view.findViewById(R.id.antenna);

        mDistance.setTitleNote(R.string.km);
        mAverageSpeed.setTitleNote(R.string.kmch);

        SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map_fragment);
        mapFragment.getMapAsync(this);
        return view;
    }

创建片段：

mMapTabFragment = MapTabFragment.getInstance(this, this);
// .. fragments used in ViewPager with CustomAdapter class:

    private class CustomAdapter extends FragmentPagerAdapter {
        CustomAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            TABS tab = TABS.values()[position];

            if (tab == TABS.MAP) {
                return mMapTabFragment;
            } else if (tab == TABS.COMPASS) {
                return mCompassTabFragment;
            } else if (tab == TABS.INFO) {
                return mInfoTabFragment;
            }

            return null;
        }

        @Override
        public int getCount() {
            return TABS.values().length;
        }

        @Override
        public CharSequence getPageTitle(int position) {
            TABS tab = TABS.values()[position];
            return getString(tab.getTitle());
        }
    }

我尝试重现问题，但没有成功。哪里错了？如果需要更多代码 - 我已准备好提供它。

这是因为当mLayoutId被调用时，字段0返回onCreateView，因为片段不会持久化它。您应该将mLayoutId放在Bundle中并将其作为参数传递给片段：

public static MapTabFragment getInstance(OnTabNaviListener listener, OnMapFragmentListener callback) {
    MapTabFragment fragment = new MapTabFragment();
    Bundle args = new Bundle();
    args.putInt("mLayoutId", R.layout.fragment_map_tab);
    fragment.setArguments(args);
    ...
    return fragment;
}

来自AbsTabFragment：

@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(getArguments().getInt("mLayoutId"), container, false);
    ...
}

android.content.res.Resources $ NotFoundException用于不同的设备或用户
