Launching Driving Directions with Lat and Long values from another activity
<p>Here's my situation:</p>

<ul>
<li>I have a list that will launch different pages for different places.</li>
<li>Each of these pages already have a WebView and MapView showing the
details and the map of the respective places (I used a TabHost)</li>
<li>I created an activity which extends ItemizedOverlay to enable me to place a marker, as well as to launch an alert dialog for my driving directions. This is used by all the MapView</li>
</ul>

<p>I am able to launch driving directions from the alert dialog through the Google Maps app from my app so far. However, I have to put the lat and long values (actual numbers) in the Uri.parse("http://maps.google.com/maps..."). </p>

<p>Is there a way to replace the lat and long values with strings from the Activity of the respective places?</p>

<p>P.S. Please pardon me as this is my first time posting here, and I am very new to programming =)</p>
