Hi,
(This application is kinda like a wardriver application)
I am attempting to plot points on a mapview however I'm having some
issues.
Following this tutorial
>http://developer.android.com/resources/tutorials/views/hello-mapview.html
And have also done some extensive browsing to try and solve my issue
without much luck (but it's got me this far).
I have the following,
private void GPSloc() {
GeoPoint arg0 = new GeoPoint(
(int) (realLat),
(int) (realLong));
mc.animateTo(arg0);
try {
ArrayList<String> ssidArray = ((scanner)
receiver).getssidArray();
//ArrayList<Integer> levelArray = ((scanner)
receiver).getlevelArray();
plotter(ssidArray, levelArray);
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable =
this.getResources().getDrawable(R.drawable.marker);
SSIDPoints itemizedoverlay = new SSIDPoints(drawable);
GeoPoint point = new
GeoPoint(getRealLati(),getRealLongi());
OverlayItem overlayitem = new OverlayItem(point,
"Avilable Wifi",
ssidArray.toString());/*debug*/
itemizedoverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedoverlay);
} catch (Exception e) {
String message = String.format(e.getMessage());
Toast.makeText(this, message,
Toast.LENGTH_LONG).show();/
*debug*/
}
That is ran via a button.
my SSIDPoints class is similar to the tutorial
import java.util.ArrayList;
import android.app.AlertDialog;
import android.content.Context;
import android.graphics.drawable.Drawable;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
public class SSIDPoints extends ItemizedOverlay {
private ArrayList<OverlayItem> mOverlays = new
ArrayList<OverlayItem>();
private Context mapTap;
public SSIDPoints(Drawable mainPointer) {
//Zoom map to the correct location for user
super(boundCenterBottom(mainPointer));
}
/*
* Populate is required to show the new point
*/
public void addOverlay(OverlayItem newPoint) {
mOverlays.add(newPoint);
populate();
}
/*
* Populate calls this method found on the link below
*/
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
/*
* auto gen'd
*/
@Override
public int size() {
// TODO Auto-generated method stub
return 0;
}
/*
* Handles map taps from the user to show the point information
<unused>
*/
public SSIDPoints(Drawable mainPointer, Context context) {
super(mainPointer);
mapTap = context;
}
@Override
protected boolean onTap(int index) {
OverlayItem item = mOverlays.get(index);
AlertDialog.Builder dialog = new AlertDialog.Builder(mapTap);
dialog.setTitle(item.getTitle());
dialog.setMessage(item.getSnippet());
dialog.show();
return true;
}
}
my getLoc() method is getting all the right information required to
plot a point (I think) however when it's ran it doesn't plot anything.
Does anyone have any ideas? I'm going insane here.
