How to plot a pre-build map from google maps on a MapView

问题

I'm trying to read a map from a link (http://maps.google.com/maps/ms?msid=216892338463540803496.000494dd57eb5ebce6db2&msa=0) and plot it on a MapView, is it possible?

As you posted more information in my previous answer ("but I don't want to parse the KML and plot point by point. I was wondering if theres a way to plot all at once"), I can now redifine my answer.

You should try these lines and adapt it to your needs:

Intent mapIntent = new Intent(Intent.ACTION_VIEW); 
Uri uri1 = Uri.parse("geo:0,0?q=http://code.google.com/apis/kml/ 
documentation/KML_Samples.kml"); 
mapIntent.setData(uri1); 
startActivity(Intent.createChooser(mapIntent, "Sample")); 

Unfortunately, you won't have any control, as this is not a MapActivity. If you plan to add more stuff on your map, you have to try my first proposal and parse yourself the kml!

You can draw on the Map with Overlays

Look at this tutorial: http://codemagician.wordpress.com/2010/05/06/android-google-mapview-tutorial-done-right/

@Override
 public void onCreate(Bundle savedInstanceState)
 {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 MapView mapView = (MapView) findViewById(R.id.mapview);
 mapView.setBuiltInZoomControls(true);

 List<Overlay> mapOverlays = mapView.getOverlays();
 Drawable drawable = this.getResources().getDrawable(R.drawable.icon);
 HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable,this);
 GeoPoint point = new GeoPoint(30443769,-91158458);
 OverlayItem overlayitem = new OverlayItem(point, "Laissez les bon temps rouler!", "I'm in Louisiana!");

 GeoPoint point2 = new GeoPoint(17385812,78480667);
 OverlayItem overlayitem2 = new OverlayItem(point2, "Namashkaar!", "I'm in Hyderabad, India!");

 itemizedoverlay.addOverlay(overlayitem);
 itemizedoverlay.addOverlay(overlayitem2);

 mapOverlays.add(itemizedoverlay);
 }
 @Override
 protected boolean isRouteDisplayed()
 {
 return false;
 }
}
