Question

我正在使用Google地图开发Android应用。我的地图片段工作得很好，但在我为我的应用设置了一个设计后，我的地图碎片中出现了这个错误：

和MapFragment.xml：

xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"

和MapFragment.java：

public class FragmentMaps extends Fragment implements OnMarkerClickListener {
private GoogleMap googleMap;
MapView mMapView;
ArrayList<LatLng> markerPoints;
private Polyline line;

public FragmentMaps() {

}



@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_maps,container, false);
    markerPoints = new ArrayList<LatLng>();
    markerPoints.add(new LatLng(35.8400065, 10.5990825));
    markerPoints.add(new LatLng(35.8400030, 10.5990825));


    mMapView= (MapView) rootView.findViewById(R.id.map);
    mMapView.onCreate(savedInstanceState);
    mMapView.onResume();

    try {
        MapsInitializer.initialize(getActivity().getApplicationContext());
        googleMap.setMyLocationEnabled(true);
    } catch (Exception e) {
        e.printStackTrace();
    }
    googleMap = mMapView.getMap();
    // latitude and longitude

    googleMap.setMyLocationEnabled(true);

    googleMap.setOnMarkerClickListener(this);

    /**googleMap.setOnMapClickListener(new OnMapClickListener() {

        @Override
        public void onMapClick(LatLng point) {
            // Already two locations
            if(markerPoints.size()>1){
                markerPoints.clear();
                googleMap.clear();
            }

            // Adding new item to the ArrayList
            markerPoints.add(point);

            // Creating MarkerOptions
            MarkerOptions options = new MarkerOptions();

            // Setting the position of the marker
            options.position(point);

            /**
     * For the start location, the color of marker is GREEN and
     * for the end location, the color of marker is RED.

            if(markerPoints.size()==1){
                options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN));
            }else if(markerPoints.size()==2){
                options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));
            }

            // Add new marker to the Google Map Android API V2
            googleMap.addMarker(options);

            // Checks, whether start and end locations are captured
            if(markerPoints.size() >= 2){
                LatLng origin = markerPoints.get(0);
                LatLng dest = markerPoints.get(1);

                // Getting URL to the Google Directions API
                String url = getDirectionsUrl(origin, dest);

                DownloadTask downloadTask = new DownloadTask();

                // Start downloading json data from Google Directions API
                downloadTask.execute(url);

            }
        }
    }
            );

     **/




    double latitude = 35.8400065;

    double longitude = 10.5990825;

    // create marker
    MarkerOptions marker = new MarkerOptions().position(
            new LatLng(latitude, longitude)).title("JetSet Café");



    // Changing marker icon
    marker.icon(BitmapDescriptorFactory
            .defaultMarker(BitmapDescriptorFactory.HUE_ROSE));

    // adding marker
    googleMap.addMarker(marker);

    marker = new MarkerOptions().position(
            new LatLng(35.835829, 10.5957462)).title("ToscanaVilla Café");

    marker.icon(BitmapDescriptorFactory
            .defaultMarker(BitmapDescriptorFactory.HUE_GREEN));
    googleMap.addMarker(marker);
    CameraPosition cameraPosition = new CameraPosition.Builder()
    .target(new LatLng(latitude,longitude)).zoom(12).build();

    googleMap.animateCamera(CameraUpdateFactory
            .newCameraPosition(cameraPosition));
    return rootView;
}

正如我之前所说的，我为我的应用程序设置了一切都很好，但在那之后，我无法获得mu地图片段的工作。

Answer 1

请使用以下布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
              android:orientation="vertical">

    <fragment
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:id="@+id/map"
         android:name="com.google.android.gms.maps.MapFragment"/>
</LinearLayout>

Answer 2

我只是添加了这个布局，它运行良好：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<com.google.android.gms.maps.MapView android:id="@+id/mapview"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" />

Google Map在二进制XML文件中膨胀异常
