jerrellmardis / ZoomFragment.java

Created April 10, 2013 22:37

This demonstrates how to implement the onTouch(...) callback method within a Fragment in order to scale/zoom out the Fragment's root view when a user drags their finger up or down. Note: You can use the nineoldandroids lib to get this to work on pre-Honeycomb devices.

	public class ZoomFragment implements OnTouchListener {

	private static final float MIN_SCALE = 0.95f;

	private float mLastScaleFactor = 0;
	private float mTouchY;

	@Override
	public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) {
	mView = inflater.inflate(R.layout.fragment_layout, container, false);
