android mapview show only markers from visible screen
<p>So I have a list of markers. I was wondering how could I just load the markers that are visible from the screen. </p>

<p>Im using ItemizedOverlay. </p>

<p>I had an idea to override the draw of the ItemizedOverlay and from there get the visible lat/long from left to right and top to bottom and see which of my markers fits within those bounds. </p>

<p>But It seems that the draw gets call all the time ... </p>

<p>Where is the best place to do this calculation? Is there an event on the map I can hook into for this?</p>
