我是android的新手...我已经在arcGIS地图上工作了2天，在arcGIS地图上显示多个引脚..我只是在调试而不是运行时才输出..我必须显示弹出窗口（标注）whren贴在pin.Please一些身体帮助我..谢谢提前..
这是我的代码
if (MyXMLHandler.getResponse().getLatitude().size() > 0) {
for (int i = 0; i < MyXMLHandler.getResponse().getLatitude()
.size(); i++) {
Log.v("TEST", "size=="
+ MyXMLHandler.getResponse().getLatitude().size());
double latitude = Double.parseDouble(MyXMLHandler
.getResponse().getLatitude().get(i).toString());
double langtude = Double.parseDouble(MyXMLHandler
.getResponse().getLongtude().get(i).toString());
Log.v("TEST", "lan........" + latitude + "....lng......"
+ langtude);
latlong = new Point(langtude, latitude);
point = (Point) GeometryEngine.project(latlong,
SpatialReference.create(4326),
mMapView.getSpatialReference());
gLayer = new GraphicsLayer();
PictureMarkerSymbol pictureMarkerSymbol = new PictureMarkerSymbol(
getResources().getDrawable(R.drawable.s));
graphic = new Graphic(point, pictureMarkerSymbol);
gLayer.addGraphic(graphic);
mMapView.addLayer(gLayer);
mMapView.setOnSingleTapListener(Arcgis_routeActivity.this);
}
@Override
public void onSingleTap(final float x, final float y) {
// TODO Auto-generated method stub
LayoutInflater inflator = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.callout_xml, null);
TextView textView1 = (TextView) v.findViewById(R.id.textView1);
textView1.setText(MyXMLHandler.getResponse().getName().get(0)
.toString());
location = new Point(x, y);
if (callout != null) {
callout.hide();
} else {
callout = mMapView.getCallout();
callout.setStyle(R.xml.calloutstyle);
}
callout.setOffset(0, -15);
callout.show(location, v);
}``

这是我发现可能有帮助的calloutPopupWindow。遗憾的是我还没有使用它，但是在API中它提到它类似于callout，并且具有能够有多个标注的额外好处。 希望这有帮助！
