我正在使用代码名称来开发一个应用程序,它具有谷歌地图,我想要当我打开应用程序它获得我当前的位置我怎么能做到这一点,这里是我的代码。google map in codename one
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());
}
}
谢谢夏嘉曦它的工作,现在我该怎样改善这种相同的代码,让标记显示我的位置移动每当我移动以及如何自动放大我的位置。 –
您可以添加/删除标记,我建议使用位置侦听器而不是此同步方法。您也可以使用API来控制相机的位置 –
