Implementing Gesture Recognition In An Android App

Question

I am adding gesture recognition to my app. I have added the view as described in the Android Developers Gestures article but when it comes to adding:

mLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures);
if(!mLibrary.load()){
   finish();
}

where do I put this in my code, do I have to create a new class for it, or can I have it in an inner class, or does it not need a class at all?! I have a set up similar to Lunar Lander which comprises of two files, one of which is a thread that handles pretty much all the physics and drawing of the game. The other file begins the thread and saveInstanceState method.

Furthermore, what type is mLibrary?! I cannot find out anywhere!!

I imagine I will put the OnGesturePerformed method in my thread as this is where I handle all keyUp and Down events.

Answer 1

your read this article http://developer.android.com/resources/articles/gestures.html I think.

after that piece of code you can see that you have to implement a listener.

public class GesturesActivity extends Activity implements OnGesturePerformedListener { public void onCreate(Bundle savedInstanceState) { .. } public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { //do the stuff you want ;) }
