Android 高德地图根据经纬度定位到指定位置，并使用icon标记

//移动到指定经纬度 private void initAMap() { AMap mAMap = mMapView.getMap(); CameraPosition cameraPosition = new CameraPosition(new LatLng(latitude, longitude), 15, 0, 30); CameraUpdate cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition); mAMap.moveCamera(cameraUpdate); drawMarkers(); } //画定位标记图 public void drawMarkers() { MarkerOptions markerOptions = new MarkerOptions() .position(new LatLng(latitude, longitude)) .icon(BitmapDescriptorFactory.fromResource(R.drawable.daohang_location)) .draggable(true); Marker marker = mAMap.addMarker(markerOptions); marker.showInfoWindow(); }

已知地址获取经纬度方法：

private void getLatlon(String cityName){ GeocodeSearch geocodeSearch=new GeocodeSearch(this); geocodeSearch.setOnGeocodeSearchListener(new GeocodeSearch.OnGeocodeSearchListener() { @Override public void onRegeocodeSearched(RegeocodeResult regeocodeResult, int i) { } @Override public void onGeocodeSearched(GeocodeResult geocodeResult, int i) { if (i==1000){ if (geocodeResult!=null && geocodeResult.getGeocodeAddressList()!=null && geocodeResult.getGeocodeAddressList().size()>0){ GeocodeAddress geocodeAddress = geocodeResult.getGeocodeAddressList().get(0); double latitude = geocodeAddress.getLatLonPoint().getLatitude();//纬度 double longititude = geocodeAddress.getLatLonPoint().getLongitude();//经度 String adcode= geocodeAddress.getAdcode();//区域编码 Log.e("lgq地理编码", geocodeAddress.getAdcode()+""); Log.e("lgq纬度latitude",latitude+""); Log.e("lgq经度longititude",longititude+""); Log.i("lgq","dddwww===="+longititude); }else { Toast.makeText(MainActivity.this,"地名出错",Toast.LENGTH_SHORT).show(); // ToastUtils.show(context,"地址名出错"); } } } }); GeocodeQuery geocodeQuery=new GeocodeQuery(cityName.trim(),"29"); geocodeSearch.getFromLocationNameAsyn(geocodeQuery); }
