Android Maps - showing two or more paths within a single mapview

Question

I want to show 2 or more paths between 2 locations similar to "Suggested Routes" in Google Maps. I am able to draw 1 path through this link J2ME Map Route Provider . Now i want to show 2 paths simultaneously.

Answer 1

You can use the J2ME Map Route Provider, you just need to change/remove this line of code:

 Handler mHandler = new Handler() {
  public void handleMessage(android.os.Message msg) {
   TextView textView = (TextView) findViewById(R.id.description);
   textView.setText(mRoad.mName + " " + mRoad.mDescription);
   MapOverlay mapOverlay = new MapOverlay(mRoad, mapView);
   List<Overlay> listOfOverlays = mapView.getOverlays();

listOfOverlays.clear();

   listOfOverlays.add(mapOverlay);
   mapView.invalidate();
  };
 };

You don't want to clear the map with each new overlay, just add it to the existing set of overlays.

This link worked perfectly for me. i called the method twice in main activity and the new overlay din`t replace the previous one.
