[Résolu] Installation d'un Listener tactile

Bonjour
Voici le code qui permet d' installer un Listener tactile sous Android:
@Override
public boolean onTouchEvent(MotionEvent e) {
// MotionEvent reports input details from the touch screen
// and other input controls. In this case, you are only
// interested in events where the touch position changed.

float x = e.getX();
float y = e.getY();

switch (e.getAction()) {
case MotionEvent.ACTION_MOVE:

float dx = x - mPreviousX;
float dy = y - mPreviousY;

// reverse direction of rotation above the mid-line
if (y > getHeight() / 2) {
dx = dx * -1 ;
}

// reverse direction of rotation to left of the mid-line
if (x < getWidth() / 2) {
dy = dy * -1 ;
}

mRenderer.mAngle += (dx + dy) * TOUCH_SCALE_FACTOR; // = 180.0f / 320
requestRender();
}

mPreviousX = x;
mPreviousY = y;
return true;
}
