Hi,
Implement a SimpleOnScaleGestureListener class for example ZoomDetector and
make and instance of it in your Gallery implementation.
In your Gallery class
public boolean onTouchEvent(MotionEvent event)
{
zoomDetector.onTouchEvent(event);
return super.onTouchEvent(event);
}
ZoomDetector class:
class ZoomDetector extends SimpleOnScaleGestureListener
{
@Override
public boolean onScale(ScaleGestureDetector detector)
{
setScaleX(getScaleX() * detector.getScaleFactor());
setScaleY(getScaleY() * detector.getScaleFactor());
return super.onScale(detector);
}
}
This may help you.
