Can you get the Android MotionEvents while using LibGDX

Question

What I am trying to do is use the android.view.GestureDetector and android.view.ScaleGestureDetector classes in Android but they appear to be disabled by LibGDX. I need to specifically get access to the MotionEvent objects which Android generates when a user touches the screen. Can anyone help point me in the right direction or confirm if indeed LibGDX is disabling them? Thanks in advance.

There is already an abstraction of the GestureDetector on libgdx. the GestureListener You can use it like this:

public class MyGestureListener implements GestureListener {

   @Override
   public boolean touchDown (int x, int y, int pointer) {
      return false;
   }

   @Override
   public boolean tap (int x, int y, int count) {
      return false;
   }

   @Override
   public boolean longPress (int x, int y) {
      return false;
   }

   @Override
   public boolean fling (float velocityX, float velocityY) {
      return false;
   }

   @Override
   public boolean pan (int x, int y, int deltaX, int deltaY) {
      return false;
   }

   @Override
   public boolean zoom (float originalDistance, float currentDistance) {
      return false;
   }

   @Override
   public boolean pinch (Vector2 initialFirstPointer, Vector2 initialSecondPointer, Vector2 firstPointer, Vector2 secondPointer) {
      return false;
   }
}

Don't forget to set it as an InputProcessor

Gdx.input.setInputProcessor(new GestureDetector(new MyGestureListener()));
