Question

当我在片段中对GoogleMaps进行充气时，我会得到error。错误行是MapsFragment：

View rootView = inflater.inflate(R.layout.map_fragment,container, false);

MainActivity：

public class MainActivity extends Activity {
    public static Context appContext;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // ActionBar gets initiated
        ActionBar actionbar = getActionBar();
        // Tell the ActionBar we want to use Tabs.
        actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        // initiating both tabs and set text to it.
        ActionBar.Tab aroundTab = actionbar.newTab().setText(getString(R.string.title_around));
        ActionBar.Tab mapTab = actionbar.newTab().setText(getString(R.string.title_map));
        ActionBar.Tab favoriteTab = actionbar.newTab().setText(getString(R.string.title_favorite));
        ActionBar.Tab achiveTab = actionbar.newTab().setText(getString(R.string.title_achievement));

        // create the two fragments we want to use for display content
         Fragment map = new MapsFragment();
         Fragment around = new AroundFragment();
         Fragment favorite = new FavoriteFragment();
         Fragment achive = new AchievementFragment();

        // Fragment StationsFragment = new BFragment();

        // set the Tab listener. Now we can listen for clicks.
         aroundTab.setTabListener(new MyTabsListener(map));
         mapTab.setTabListener(new MyTabsListener(around));
         favoriteTab.setTabListener(new MyTabsListener(favorite));
         achiveTab.setTabListener(new MyTabsListener(achive));

        // add the two tabs to the actionbar
        actionbar.addTab(aroundTab);
        actionbar.addTab(mapTab);
        actionbar.addTab(favoriteTab);
        actionbar.addTab(achiveTab);
    }
}

MapsFragment：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.map_fragment,container, false);
    map = ((MapFragment)getActivity().getFragmentManager().findFragmentById(R.id.map)).getMap();
    map.setMyLocationEnabled(true);
    map.setMapType(GoogleMap.MAP_TYPE_NORMAL);

    mMapFragment = MapFragment.newInstance();
    FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
    fragmentTransaction.add(R.id.map,mMapFragment);
    fragmentTransaction.commit();
    return rootView;
}

Answer 1

在android:name类的布局文件中指定MapsFragment属性：

<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.jertt.yummymap.MapsFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
