Creating New Activity Screen from within ItemizedOverlay

I am trying to make some clickable map overlays that trigger a new screen to appear when a user taps on the markers. I have a mapview setup that creates markers using the ItemizedOverlay. Inside of ItemizedOverlay I override onTap(), I know that this work when clicking on the markers. How can I create a new screen from within ItemizedOverlay?

I am having trouble because I cannot use startActivity() since Activity is not extending, ItemizedOverlay is.

Any ideals?

Thanks.

Just pass the context of the activity to the constructor of your itemizedoverlay.

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
class bla extends Activity {
 
    ...
 
    MyItemOverlay io = new MyItemOverlay(this);
 
    ...
 
}
 
class MyItemOverlay extends ...... {
 
    private Context ctx;
 
    public MyItemOverlay(Context context) {
 
        this.ctx = context;
 
    }
 
    protected boolean onTap(...) {
 
        ctx.startActivity(...);
 
    }
 
}
 
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

Something like that....
