Workflow of the Java-only cubes sample
Java Main Activity
When the user starts the application, the
JavaGLActivity.onCreate()
method will be called (see Listing 5-2).
Here is where the surface view (
mGLSurfaceView
) is initialized and set as the application content:
mGLSurfaceView = new GLSurfaceView(this);
mGLSurfaceView.setRenderer(new CubeRenderer(true));
setContentView(mGLSurfaceView);
Note that the GL surface view must use a renderer (
CubeRenderer
in this case), which implements
the
Renderer
interface and takes a Boolean argument indicating if a translucent background should be
used.
