代号一的谷歌地图

Question

我正在使用代号 one 开发一个包含谷歌地图的应用程序，我希望当我打开应用程序时它会获取我当前的位置我该怎么做，这是我拥有的代码。

    static Location lastKnownLocation;
@Override
protected void beforeMap(Form f) {
    MapContainer mapContainer = new MapContainer(new GoogleMapsProvider("AIzaSyCyy_vOWn3DvR3Y8pzAWUmKTzBaDa81Tfc"));
    lastKnownLocation = LocationManager.getLocationManager().getLastKnownLocation();
    Style s = new Style();
    s.setBgTransparency(0);
    s.setFgColor(0);
    mapContainer.addMarker(FontImage.createMaterial(FontImage.MATERIAL_MY_LOCATION, s).toEncodedImage(), new Coord(lastKnownLocation.getLatitude(), lastKnownLocation.getLongitude()), "", "", evt -> {
        ToastBar.showErrorMessage(lastKnownLocation.toString());
    });
    mapContainer.addTapListener(evt -> {
        Coord coord = mapContainer.getCoordAtPosition(evt.getX(), evt.getY());
        mapContainer.addMarker(FontImage.createMaterial(FontImage.MATERIAL_LOCATION_ON, s).toEncodedImage(), coord, "", "", null);
    });

    f.add(BorderLayout.CENTER, mapContainer);
     FloatingActionButton fab = FloatingActionButton.createFAB(FontImage.MATERIAL_ADD);
    fab.addActionListener(e -> {
        ParseObject object = ParseObject.create("Geo");
        object.put("current", new ParseGeoPoint(lastKnownLocation.getLatitude(), lastKnownLocation.getLongitude()));
        if (ParseUser.getCurrent() != null)
            object.put("user", ParseUser.getCurrent());
        try {
            object.save();
            ToastBar.showErrorMessage("Geo Sent");
        } catch (ParseException ex) {
            ex.printStackTrace();
            ToastBar.showErrorMessage(ex.getMessage());
        }
    });
    fab.bindFabToContainer(f.getContentPane());
}

}

请注意，在设备上将使用并突出显示您的当前位置，因为设备运行本机地图，而模拟器运行模拟。

话虽如此，您可以从 LocationManager 类中获取您的位置。

例如：

Location position = LocationManager.getLocationManager().getCurrentLocationSync();
