好的，所以我正在覆盖 MyLocationOverlay 以希望移除蓝色准确环。

我正在覆盖 drawMyLocation()

 @Override 
        protected void drawMyLocation(Canvas canvas, MapView mapView, Location lastFix, GeoPoint myLocation, long when) {
            // translate the GeoPoint to screen pixels
            Point screenPts = mapView.getProjection().toPixels(myLocation, null);



            // create a rotated copy of the marker
            Bitmap arrowBitmap = BitmapFactory.decodeResource( mContext.getResources(), android.THISISWHERETHEANIMATIONSHOULDGO);
            Matrix matrix = new Matrix();
            matrix.postRotate(mOrientation);
            Bitmap rotatedBmp = Bitmap.createBitmap(
                arrowBitmap, 
                0, 0, 
                arrowBitmap.getWidth(), 
                arrowBitmap.getHeight(), 
                matrix, 
                true
            );
            // add the rotated marker to the canvas
            canvas.drawBitmap(
                rotatedBmp, 
                screenPts.x - (rotatedBmp.getWidth()  / 2), 
                screenPts.y - (rotatedBmp.getHeight() / 2), 
                null
            );


        }

但是，我发现无法获得对所使用的原始蓝点动画的引用。我该如何重新添加这个？一帧动画是可以接受的。谢谢。

你不能只使用位置来知道用户的位置吗？
