问题描述
我如何添加气球像谷歌地图（如这里显示一个）为OpenStreetMap的？这是我的OpenStreetMap $ C $低于C：

}
@覆盖
公共布尔onSnapToItem（INT为arg0，诠释ARG1，ARG2点，IMapView ARG3）{

}
@覆盖
保护OverlayItem createItem中（INT为arg0）{
// TODO自动生成方法存根
返回overlayItemList.get（为arg0）;
}
@覆盖
公众诠释大小（）{
// TODO自动生成方法存根
返回overlayItemList.size（）;
}
}
解决方案
我是同一个问题，现在我找到了一个方法：
-
下载 osmbonuspack 在这里：的https：/ /$c$c.google.com/p/osmbonuspack/
-
按照此code：
的ArrayList＆LT; ExtendedOverlayItem＆GT; overlayItemArray =新的ArrayList＆LT; ExtendedOverlayItem＆GT;（）; ExtendedOverlayItem项目=新ExtendedOverlayItem（标题，描述，新的GeoPoint（双纬度，经度双），这一点）; //创建一个层气球 ItemizedOverlayWithBubble＆LT; ExtendedOverlayItem＆GT; poiMarkers =新ItemizedOverlayWithBubble＆LT; ExtendedOverlayItem＆GT;（这一点，overlayItemArray，图形页面，新的CustomMapInfoWindow（图形页面））; //添加图层 。调用MapView.getOverlays（）加（poiMarkers）; -
创建了一个名为 CustomMapInfoWindow
进口org.osmdroid.bonuspack.overlays.DefaultInfoWindow; 进口org.osmdroid.bonuspack.overlays.ExtendedOverlayItem; 进口org.osmdroid.views.MapView; 公共类CustomMapInfoWindow扩展DefaultInfoWindow { 公共CustomMapInfoWindow（图形页面图形页面）{ 超（R.layout.bonuspack_bubble，图形页面）; } @覆盖 公共无效的OnOpen（ExtendedOverlayItem项目）{ super.onOpen（项目）; } } -
到<一个href="https://$c$c.google.com/p/osmbonuspack/source/browse/#svn%2Ftrunk%2FOSMBonusPackDemo%2Fres%2Flayout"相对=nofollow> OSMBONUSPACKDEMO REPOSITORY 并获得 bonuspack_bubble.xml 和可绘制到绘制-MDPI 的文件夹。
How do I add balloons like those on Google Maps (such as the one shown here) into OpenStreetMap? This is my OpenStreetMap code below:
import org.osmdroid.DefaultResourceProxyImpl;
import org.osmdroid.ResourceProxy;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapView;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;
import android.os.Bundle;
import android.app.Activity;
import android.graphics.drawable.Drawable;
public class MainActivity extends Activity {
MyItemizedOverlay myItemizedOverlay = null;
private MapController myMapController;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
myMapController = mapView.getController();
myMapController.setZoom(16);
Drawable marker=getResources().getDrawable(android.R.drawable.star_big_on);
int markerWidth = marker.getIntrinsicWidth();
int markerHeight = marker.getIntrinsicHeight();
marker.setBounds(0, markerHeight, markerWidth, 0);
ResourceProxy resourceProxy = new
DefaultResourceProxyImpl(getApplicationContext());
myItemizedOverlay = new MyItemizedOverlay(marker, resourceProxy);
mapView.getOverlays().add(myItemizedOverlay);
GeoPoint myPoint1 = new GeoPoint(24.893379000000000000, 67.028060900000010000);
myItemizedOverlay.addItem(myPoint1, "myPoint1", "myPoint1");
GeoPoint myPoint2 = new GeoPoint(24.824796300000000000, 67.031565699999990000);
myItemizedOverlay.addItem(myPoint2, "myPoint2", "myPoint2");
}
}
import java.util.ArrayList;
import org.osmdroid.ResourceProxy;
import org.osmdroid.api.IMapView;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.overlay.ItemizedOverlay;
import org.osmdroid.views.overlay.OverlayItem;
import android.graphics.Point;
import android.graphics.drawable.Drawable;
public class MyItemizedOverlay extends ItemizedOverlay<OverlayItem> {
private ArrayList<OverlayItem> overlayItemList = new ArrayList<OverlayItem>();
public MyItemizedOverlay(Drawable pDefaultMarker,
ResourceProxy pResourceProxy) {
super(pDefaultMarker, pResourceProxy);
// TODO Auto-generated constructor stub
}
public void addItem(GeoPoint p, String title, String snippet){
OverlayItem newItem = new OverlayItem(title, snippet, p);
overlayItemList.add(newItem);
populate();
}
@Override
public boolean onSnapToItem(int arg0, int arg1, Point arg2, IMapView arg3) {
// TODO Auto-generated method stub
return false;
}
@Override
protected OverlayItem createItem(int arg0) {
// TODO Auto-generated method stub
return overlayItemList.get(arg0);
}
@Override
public int size() {
// TODO Auto-generated method stub
return overlayItemList.size();
}
}
解决方案
I was with the same question and now I found a way:
Download the osmbonuspack here: https://code.google.com/p/osmbonuspack/
Follow this code:
ArrayList<ExtendedOverlayItem> overlayItemArray = new ArrayList<ExtendedOverlayItem>(); ExtendedOverlayItem item = new ExtendedOverlayItem("Title, "Description, new GeoPoint(Double latitude, Double longitude), this); //creates a layer with ballons ItemizedOverlayWithBubble<ExtendedOverlayItem> poiMarkers = new ItemizedOverlayWithBubble<ExtendedOverlayItem>(this, overlayItemArray, mapView, new CustomMapInfoWindow(mapView)); // add the layer mapView.getOverlays().add(poiMarkers);Create a class called CustomMapInfoWindow:
import org.osmdroid.bonuspack.overlays.DefaultInfoWindow; import org.osmdroid.bonuspack.overlays.ExtendedOverlayItem; import org.osmdroid.views.MapView; public class CustomMapInfoWindow extends DefaultInfoWindow { public CustomMapInfoWindow(MapView mapView) { super(R.layout.bonuspack_bubble, mapView); } @Override public void onOpen(ExtendedOverlayItem item) { super.onOpen(item); } }Go to OSMBONUSPACKDEMO REPOSITORY and get bonuspack_bubble.xml and the drawables into drawable-mdpi folder.
