从我的android程序中我使用了Openstreetmap，然后使用它在overlay上绘制多边形。我在数组中保存了x坐标和y坐标。现在我需要在我的数据库中传递这个坐标（POstgresql）我已在我的数据库中定义了一个多边形类型数据。为此，我尝试了这些代码。
Overlay touchOverlay = new Overlay(this){
ItemizedIconOverlay<OverlayItem> anotherItemizedIconOverlay = null;
@Override
protected void draw(Canvas arg0, MapView arg1, boolean arg2) {
}
@Override
public boolean onSingleTapConfirmed(final MotionEvent e, final MapView mapView) {
mapview.invalidate();
proj = mapView.getProjection();
loc = (GeoPoint) proj.fromPixels((int)e.getX(), (int)e.getY());
longitude = Double.toString(((double)loc.getLongitudeE6())/1000000);
latitude = Double.toString(((double)loc.getLatitudeE6())/1000000);
myPath.addPoint(loc);
mPoints.add(new Point(loc.getLatitudeE6(),loc.getLongitudeE6()));
xcor.add(((double)loc.getLongitudeE6())/1000000);
ycor.add(((double)loc.getLatitudeE6())/1000000);
return true;
}
}
我使用Asynctask来调用php
private void postData() {
InputStream isr = null;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.5.1/project/spatial.php");
try {
JSONArray listx = new JSONArray();
JSONArray listy = new JSONArray();
for (int i = 0; i < xcor.size(); i++) {
listx.put(xcor.get(i));
listy.put(ycor.get(i));
}
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("value1", listx.toString()));
params.add(new BasicNameValuePair("value2", listy.toString()));
httppost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
isr = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(isr,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
isr.close();
String result=sb.toString();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
如何使用此坐标以数据库????
