Question

我想要显示的地图有一个奇怪的问题。有时崩溃，下一个错误：“二进制XML文件行＃8：二进制XML文件行＃8：错误膨胀类片段”有时它显示带有Google徽标的灰色背景（如谷歌地图的背景）。我已经搜索并尝试了很多来解决问题，但没有成功。这是代码：

public class MapFragment extends Fragment implements OnMapReadyCallback{

    private GoogleMap mMap;

    public MapFragment() {
        // Required empty public constructor
    }

    public static MapFragment newInstance() {
        MapFragment fragment = new MapFragment();
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view=inflater.inflate(R.layout.fragment_map, container, false);

        SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

        return view;
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        this.mMap = googleMap;
    }

    // TODO: Rename method, update argument and hook method into UI event
    public void onButtonPressed(Uri uri) {

    }

    public interface OnMapFragmentInteractionListener {
        // TODO: Update argument type and name
        void onMapFragmentInteraction(Uri uri);
    }

    public void updateMap(String latitude, String longitude){
        mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(Double.parseDouble(latitude),Double.parseDouble(longitude)),15));
    }
}

和xml文件：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.andrei.myapp.MapFragment">

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/map"
        class="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

当您使用SupportMapFragment Fragment时，com.google.android.gms.maps.MapView使用SupportMapFragment代替<com.google.android.gms.maps.MapView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/map" />

MapFragment

您的public class MapFragment extends Fragment { MapView mapView; GoogleMap mMap; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_map, container, false); mapView = (MapView) view.findViewById(R.id.map); mapView.onCreate(savedInstanceState); mMap = mapView.getMap(); mMap.getUiSettings().setMyLocationButtonEnabled(false); mMap.setMyLocationEnabled(true); try { MapsInitializer.initialize(this.getActivity()); } catch (GooglePlayServicesNotAvailableException e) { e.printStackTrace(); } CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(13.1, -37.9), 10); mMap.animateCamera(cameraUpdate); return view; } @Override public void onResume() { mapView.onResume(); super.onResume(); } @Override public void onPause() { super.onPause(); mapView.onPause(); } @Override public void onDestroy() { super.onDestroy(); mapView.onDestroy(); } }课程如下：

set list
set lischars=space:.

希望这会有所帮助〜
