问题描述

我试图找到一种方法，针尖标记的地方，我的纬度，经度上的谷歌地图。

I'm trying to find a way to place a pinpoint marker to my lat, long on Google Maps.

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import android.os.Bundle;

public class Nav10 extends MapActivity {
    MapController mControl;
    GeoPoint GeoP;
    MapView navView10;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.nav10);

        navView10 = (MapView) findViewById(R.id.navView10);
        navView10.displayZoomControls(true);
        navView10.setBuiltInZoomControls(true);
        navView10.setSatellite(true);

        double lat = 40.325874;
        double longi = -76.002211;

        GeoP = new GeoPoint((int) ( lat *1E6), (int) (longi * 1E6));

        mControl = navView10.getController();
        mControl.animateTo(GeoP);
        mControl.setZoom(20);
    }

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

}

我将如何插入这个code针尖标记？

推荐答案

您可以使用的 MyLocationOverlay 。你只需将它添加到您MapView类：

You can use MyLocationOverlay. You just need to add it to your mapView:

mapView.getOverlays().add(new MyLocationOverlay(context,mapView) );
