Re: [android-developers] Overlay item in ImageView

Thanks for your answer.
That's actually what I'm doing.

The problem with this approach is that once I render the component as a popover it becomes part of the bitmap. It becomes painful to handle events since I have to recognize the area in the image where the component was rendered. Also I have to deal with pan and zoom, what changes the component coordinates. I could handle all that using matrix transformations but the code is becoming messy,

I was looking for another approach, similar  to the MapsAPI, (where I can include ItemizedOverlay items), but now using to the maps API. Something that allows work with my popover as a component.

subclass the ImageView and draw overlay on onDraw and handle the touch events on onTouch

Hi,

In my application I need to show a custom popover over an ImageView. 
This tutorial (http://www.techjini.com/blog/2010/11/23/creating-a-customized-popover-for-mapview/) teaches how to do it over an MapView. 
I made an adaptation drawing the popover component in the ImageView since the ItemizedOverlay belongs to the maps API.

So far so good, but now I need to capture events in the popover and I'm questioning myself if thats the right way implement an popover over an ImageView.
Could anyone point me to a right API to build this feature?

Thanks a lot,
Luiz
