The problem goes like this:

I have implemented a surface view that gets rendered every 50 ms using the manual draw(canvas) method.
it works fine when i do instantiation and setContentView() upon activity's OnCreate event as such:

// Activity onCreate Event...

xxx = new myView();
setContentView(xxx);


However, when i have an XML layout, with a few buttons on it, and I change the Activity's OnCreate event to setContentView() to an XML layout first :

setContentView(R.layout.main);

,and then in one of my buttons' onClick, i do setContentView() to my SurfaceView
using the exact code previously ...

xxx = new myView();
setContentView(xxx);

but i get a blank screen upon changing the view from XML layout view to my own Surface View, in which i don't see any canvas drawing completely.....


WHY????
