Question

即使我的XML中有2个坐标，我的地图上也只显示一个标记。我错过了什么？

我的XML

<?xml version="1.0" encoding="utf-8"?>
<markers>
<marker> 
<lat>51.615325</lat>
<lng>0.524572</lng>
<icon>flat</icon>
</marker>
<marker><lat>51.60002</lat>
<lng>0.518862</lng>
<icon>house</icon>
</marker>
</markers>

Answer 1

更改为

mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.the_map)).getMap();
ArrayList<Entry> entries= (ArrayList<Entry>) new ParserParsing().parse(is);
for(int i=0;i>entries.size();i++)
{
Double latitude = Double.valueOf(entries.get(i).lat);
Double longitude = Double.valueOf(entries.get(i).lng);
String icon = entries.get(i).icon;
LatLng lng = new LatLng(latitude,longitude);
mMap.addMarker(new MarkerOptions()
.position(lng)
.title(icon)
.icon(BitmapDescriptorFactory.fromResource(getResources().getIdentifier(icon, "drawable", getPackageName()))));
}
