给定经纬度，获取位置名称

Question

我正在开发一个应用程序，其中我在我的 android 设备中获取纬度、经度并将它们发布到网络服务器。

在网络应用程序中，我借助谷歌地图显示位置详细信息。

在这里，我收集了大量 lat long 值，我将其循环到我的 jsp 中并使用信息窗口创建多个标记。

现在的问题是我需要在谷歌地图的信息窗口中显示特定纬度和经度的位置名称。

谁能帮助我使用 google maps 脚本，或者我如何从我的 android 手机本身的 lat long 值中获取位置名称，以便我可以将其发布到我的网络服务器。

Answer 1

这里给了我一个，只需在这个函数中传递纬度和经度，然后你就得到了与这个纬度和经度相关的所有信息。

public void getAddress(double lat, double lng) {
    Geocoder geocoder = new Geocoder(HomeActivity.mContext, Locale.getDefault());
    try {
        List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
        Address obj = addresses.get(0);
        String add = obj.getAddressLine(0);
        add = add + "\n" + obj.getCountryName();
        add = add + "\n" + obj.getCountryCode();
        add = add + "\n" + obj.getAdminArea();
        add = add + "\n" + obj.getPostalCode();
        add = add + "\n" + obj.getSubAdminArea();
        add = add + "\n" + obj.getLocality();
        add = add + "\n" + obj.getSubThoroughfare();

        Log.v("IGA", "Address" + add);
        // Toast.makeText(this, "Address=>" + add,
        // Toast.LENGTH_SHORT).show();

        // TennisAppActivity.showDialog(add);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
    }
}

Answer 2

Geocoder myLocation = new Geocoder(yourContext, Locale.getDefault());
List<Address> myList = myLocation.getFromLocation(Double.parseDouble(latitude),Double.parseDouble(longitude), 1);
Address address = (Address) myList.get(0);
String addressStr = "";
addressStr += address.getAddressLine(0) + ", ";
addressStr += address.getAddressLine(1) + ", ";
addressStr += address.getAddressLine(2);

StringBuilder _homeAddress = null;
        try{
            _homeAddress = new StringBuilder();
            Address address = null;
            List<Address> addresses = _coder.getFromLocation(_lat,_lon,1);
            for(int index=0; index<addresses.size(); ++index)
            {
                address = addresses.get(index);
                _homeAddress.append("Name: " + address.getLocality() + "\n");
                _homeAddress.append("Sub-Admin Ares: " + address.getSubAdminArea() + "\n");
                _homeAddress.append("Admin Area: " + address.getAdminArea() + "\n");
                _homeAddress.append("Country: " + address.getCountryName() + "\n");
                _homeAddress.append("Country Code: " + address.getCountryCode() + "\n");
                _homeAddress.append("Latitude: " + address.getLatitude() + "\n");
                _homeAddress.append("Longitude: " + address.getLongitude() + "\n\n");
            }
        }
        catch(Exception e){
            
        }

使用android.location.geocoder.getFromLocation(double latitude, double longitude, int maxResults)

它会给你一个地址列表。

   private String getAddress() {
        GPSTracker   gps = new GPSTracker(ProductList.this);
        Geocoder geocoder = new Geocoder(ProductList.this, Locale.getDefault());
