• I use a ImageView in a scroll view. Scroll view takes care of the zoom, here is the code I use for the double tap and swipe(still needs improvement):

  If you were having issues with the scroll view I would try working with the latest build since it addresses many Android issues. My version works for iPhone.

  If you make any improvements please post…

  scrollView.addEventListener('scale', function(e)
  {
      currentScale = e.scale;
  });
  
  scrollView.addEventListener('swipe', function(e)
  {
      if (e.direction = "left")
      {
          leftButton.fireEvent('click');
      }
  
      if (e.direction = "right")
      {
          rightButton.fireEvent('click');
      }
  });
  
  scrollView.addEventListener('doubletap', function(e)
  {
      if (currentScale > theZoomScale)
      {    Ti.API.info("Zoomed at: " + e.x + ", " + e.y + " zoom: " + currentScale);
          scrollView.zoomScale = theZoomScale;
      }
      else
      {    Ti.API.info("Not zoomed at: " + e.x + ", " + e.y + " zoom: " + currentScale);
          scrollView.scrollTo(e.x, e.y);
          scrollView.zoomScale = 2;        
      }
  });
  

• Did you ever find an answer?
  I have the same problem. Im creating a custom floorplan map, where I need it to work with Android.

  I have a post on this matter as well, but no solution: http://developer.appcelerator.com/question/117930/custom-map-issue-on-android

  Please give me a hint if you solved it.. :)

• I found a workaround, cause i was running in the same trouble

  here is my code

  pictures.photosView = Ti.UI.createScrollableView({
                      width : 320,
                      height : 367,
                      contentWidth:320,
                      contentHeight:367,
                      top : 0
                  });
  
                  for( i = 0; i < galleryImages.length; i++) {
                      lightapps.basic.log(galleryImages[i].url);
  
                      var imageView = Ti.UI.createWebView({
                          size: {
                              width: 320,
                              height: 367
                          },
                          scalesPageToFit: true,
                          html:'<img src="'+galleryImages[i].url+'" width="100%" height="100%" /></center>'
                      });
  
                      viewArray[i] = imageView;
                  }
  
                  pictures.photosView.views = viewArray;
  
                  pictures.parentView.add(pictures.photosView);
