SetContentView Of Activity Within Activities Current View?

So I have my main activity. It starts out adding a custom SurfaceView called DrawView as the content view with

DrawView drawview = new DrawView(parameters);
this.setContentView(drawview);

now my layout.main.xml is a layout with a video view which I am using to play my cutscenes. I am able to switch to this view by calling a method I made which switches the content view by

this.setContentView(R.layout.main);

which works fine when I am calling this method within the Activity. Only problem is I need to call this method from within DrawView! The method I made to switch to my cutscene is public and I do pass the Activity (named Draw) as a parameter of DrawView.

So when I do call this method from within DrawView my game freezes and will subsequently crash! however it works when method is called locally?
