SurfaceView in layout?

Question

Android

Such question:
Described Surface in layout.

<SurfaceView
android:id="@+id/surfaceView1"
android:layout_width="wrap_content"
android:layout_height="match_parent"  />

How can I bind my class to it now?
In the examples, the surfaceview is called through the main activity class.
setContentView(new MySurfaceView(this));
But I already have a SurfaceView in the layout, so I call:
setContentView(R.layout.activity_main);

Answer 1

SurfaceView view = (SurfaceView) findViewById(R.id.surfaceView1); 

won't work?
