rendering

I have a complex custom view - photo collage.

What is observed is whenever any UI interaction happens, the view is redrawn.

How can I avoid complete redrawing (for example, use a cached UI) of the view specially when I click the "back" button to go back to previous activity because that also causes redrawing of the view.

While exploring the API and web, I found a method - getDrawingCache() - but don't know how to use it effectively.

How do I use it effectively?

I've had other issues with Custom Views that I outline here.
