Coding the game loop

We said that we will not be using a UI layout for our game screen, but instead a dynamically drawn view. This is where the view of our pattern comes in. Let's create a new class to represent our view, then we will put in the fundamental building blocks of our Tappy Defender game.

Building the view

We will leave our two activity classes alone for a while so that we can take a look at our class that will represent the view of our game. As we discussed at the start of this chapter, the view and the controller aspects will be part of the same class.

The Android API provides us with an ideal class for our requirements. The android.view.SurfaceView class not only provides us a view that is designed for drawing pixels, text, lines, and sprites onto, but also enables us to quickly handle player input as well.

As if this wasn't useful enough, we can also spawn a thread by implementing the runnable interface allowing our main game loop to get player input and other system...
