Android Google Maps将标记位置保存到MySQL数据库

我对安卓和一般编程都很陌生。我正在开发一个Android应用程序，允许用户在Google地图上放置一个标记，一旦放置了标记，其位置（纬度和经度）将上传到存储在服务器上的外部MySQL数据库

为了让我的谷歌地图在Android上正常工作，我遵循了以下系列教程：

现在我想能够上传纬度和经度到我的数据库，我不知道怎么做

这是我现在拥有的代码：

public class Main extends MapActivity implements LocationListener{
/** Called when the activity is first created. */

//set variables
MapView map; //set map to mapview
long start; //create a starting point when the user presses down on the map
long stop; //create a stop point when the user stops pressing down on the map
MapController controller; //create a map controller that animates where the user is going through the map activity
int x, y; //x and y position on the overlay when the user touches the screen
GeoPoint touchedPoint; //create a geopoint as touchedPoint
Drawable d; //create drawable item
List<Overlay> overlayList; //setup list of overlays
LocationManager lm; //setup location manager
String towers; //setup string called towers
int lat; //create lattitude for the phone's current position
int longi; //create longitude for the phone's current position
private ArrayList<ToDoItem> todoItems;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    map = (MapView)findViewById(R.id.mvMain);//set map to mapview in the main.xml
    map.setBuiltInZoomControls(true);//zoom function


    Touchy t = new Touchy();//new instance of touchy class
    overlayList = map.getOverlays();//list of overlays
    overlayList.add(t);//add touchy instance (t) to a list of overlays
    controller = map.getController();//setup controller
    GeoPoint point = new GeoPoint(51643234, 7848593);//setup geopoint
    controller.animateTo(point);//animate controller to that location
    controller.setZoom(6);//set zoom level

    //create drawable item and its location
    d = getResources().getDrawable(R.drawable.yellow);

    //Placing marker at location
    //retrieve location manager for controlling the location updates 
    lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    Criteria crit = new Criteria();//setup criteria


    towers = lm.getBestProvider(crit, false);//return the provider that best fits the given criteria
    Location location = lm.getLastKnownLocation(towers);//access location through location manager and get the last known location called towers

    if (location != null){
        lat = (int) (location.getLatitude() *1E6);//get latitude
        longi = (int) (location.getLongitude() *1E6);//get longitude
        //add overlay to the list
        GeoPoint ourLocation = new GeoPoint(lat, longi);//setup geopoint as ourLocation with lat and long
        OverlayItem overlayItem = new OverlayItem(ourLocation, "Hello", "2nd String");//pass in outLocation to OverlayItem
        CustomMarker custom = new CustomMarker(d, Main.this);
        custom.insertPinpoint(overlayItem);
        overlayList.add(custom);
    }else{
        Toast.makeText(Main.this, "Couldn't find provider", Toast.LENGTH_SHORT).show();
    }

}

@Override
protected void onPause(){
    super.onPause();
    //when pause is pressed remove location updates
    lm.removeUpdates(this);
}

@Override
protected void onResume(){
    super.onResume();
    //when the resume is pressed request location updates
    lm.requestLocationUpdates(towers, 500, 1, this);
}

@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}


//overlay class that handles all touch events
class Touchy extends Overlay{
    public boolean onTouchEvent(MotionEvent e, MapView m){ //onTouchEvent method which includes a motion even and a map view
    if(e.getAction() == MotionEvent.ACTION_DOWN){ //when the user presses down on the overlay
        start = e.getEventTime();//start point when the event happens 
        x = (int) e.getX();//x and y coordinates based on where the user touched the overlay
        y = (int) e.getY();
        touchedPoint = map.getProjection().fromPixels(x, y);//sets a geopoint based on where the user has touched on the screen. Relates the map activity to the user's actual touch on the overlay

    }
    if (e.getAction() == MotionEvent.ACTION_UP){ //when the user stops pressing down on the overlay
        stop = e.getEventTime();//stop point when the event happens
    }
    if (stop - start > 1500){ //if the user presses on the overlay for more than 1.5 seconds
        AlertDialog alert = new AlertDialog.Builder(Main.this).create();//setup alert dialog for the Main class
        alert.setTitle("Pick an Option");//set the title for the alert
        alert.setMessage("Please pick an option");//set the message for the alert


        //BUTTON 1
        //set a button for the alert. Refer to a dialogue interface for this OnClickListener
        alert.setButton("Place a Marker", new DialogInterface.OnClickListener() {

            //when the button is clicked
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub

                OverlayItem overlayItem = new OverlayItem(touchedPoint, "Hello", "2nd String");//setup overlay item and refer to touchedPoint which is geopoint
                CustomMarker custom = new CustomMarker(d, Main.this);//setup a custom marker with a "d" in the Main class
                custom.insertPinpoint(overlayItem);//add an overlayItem to the pinpoint array list
                overlayList.add(custom);//add custom overlay to the overlay list
                map.invalidate();//make MapView draw itself
                SaveRemote();
            }
        });

我非常感谢您的帮助，因为我不知道如何将标记的位置发送到SaveRemote方法，而SaveRemote方法又会将这些数据发送到php文件

谢谢你

嘿，我可能有点晚了，但是你可以使用setonmarkerdragstener解决这个问题，比如：

          map.setOnMarkerDragListener(new GoogleMap.OnMarkerDragListener() {
                @Override
                public void onMarkerDragStart(Marker marker) {
                    //Toast.makeText(TerminosYC.this.getActivity(), "Arrastra el marcador, hasta el lugar deseado",
                    //        Toast.LENGTH_SHORT).show();
                    LatLng position = marker.getPosition();
                    map.animateCamera(CameraUpdateFactory.newLatLngZoom(
                            new LatLng(position.latitude, position.longitude), 15));
                }

                @Override
                public void onMarkerDrag(Marker marker) {
                      //       System.out.println("Arrastrando...");
                    LatLng position = marker.getPosition();
                    map.animateCamera(CameraUpdateFactory.newLatLngZoom(
                            new LatLng(position.latitude, position.longitude), 15));
                }

                @Override
                public void onMarkerDragEnd(Marker marker) {
                    LatLng position = marker.getPosition();
                    latitudeeeee = position.latitude;
                    longitudeeee = position.longitude;
                    //Toast.makeText(
                    //        TerminosYC.this.getActivity(),
                    //        "Lat " + position.latitude + " "
                    //                + "Long " + position.longitude,
                    //        Toast.LENGTH_LONG).show();


                    //map.animateCamera(CameraUpdateFactory.newLatLngZoom(
                    //        new LatLng(position.latitude, position.longitude), 15));

                }
            });

        }

这是一篇很老的帖子——你是已经“自助”了，还是仍然停留在那里？基本上，方法是从您的地质点提取坐标，然后使用REST/Json提交它们。我非常感谢您，因为您在5年后就回答了这个问题。欢迎您，您的努力是值得的。那很酷。
