Hello All,
I am having 4 static Geopoints, I am able to mark them on the Map and also i
am able to draw line between them.
Now i am trying to animate the line while drawing between 2 Geopoints, i
just want to show them some kind of animation while drawing line .. is it
possible to do ?? or i can call some delay function ??
Please help me with this ..
My function
public class HelloMapView extends MapActivity {
/** Called when the activity is first created. */
LinearLayout linearLayout;
MapView mapView;
MapController mc;
GeoPoint p,p1,p2,p3;
class MapOverlay extends com.google.android.maps.Overlay
{
@Override
public boolean draw(Canvas canvas, MapView mapView,
boolean shadow, long when)
{
super.draw(canvas, mapView, shadow);
//---translate the GeoPoint to screen pixels---
Point screenPts = new Point();
mapView.getProjection().toPixels(p, screenPts);
//---add the marker---
Bitmap bmp = BitmapFactory.decodeResource(
getResources(), R.drawable.a);
canvas.drawBitmap(bmp, screenPts.x, screenPts.y-35, null);
//Coordinates 2
//---translate the GeoPoint to screen pixels---
Point screenPts1 = new Point();
mapView.getProjection().toPixels(p1, screenPts1);
//---add the marker---
Bitmap bmp1 = BitmapFactory.decodeResource(
getResources(), R.drawable.b);
canvas.drawBitmap(bmp1, screenPts1.x, screenPts1.y-35, null);
//Coordinates 3
//---translate the GeoPoint to screen pixels---
Point screenPts2 = new Point();
mapView.getProjection().toPixels(p2, screenPts2);
//---add the marker---
Bitmap bmp2 = BitmapFactory.decodeResource(
getResources(), R.drawable.c);
canvas.drawBitmap(bmp2, screenPts2.x, screenPts2.y-35, null);
//Coordinates 4
//---translate the GeoPoint to screen pixels---
Point screenPts3 = new Point();
mapView.getProjection().toPixels(p3, screenPts3);
//---add the marker---
Bitmap bmp3 = BitmapFactory.decodeResource(
getResources(), R.drawable.dgreen);
canvas.drawBitmap(bmp3, screenPts3.x, screenPts3.y-35, null);
//----------- Start--------------//
Paint mPaint = new Paint();
mPaint.setStyle(Style.FILL);

//canvas.drawPath(path,mPaint);
super.draw(canvas, mapView, shadow);
canvas.drawLine(screenPts.x, screenPts.y, screenPts1.x,
