gesture

If you have used the Google Maps web app on your iphone or ipad you know what i am talking about. You can't see my fingers in this screen grab, but this is mid-pinch (if you will) zooming out. The detailed area was the initial map viewing area and the blurry bit outside is the extra map that has come into view mid-pinch. The pinch-to-zoom function that uses the gesture touch input scales the map currently in view live in a way that is so smooth it looks like magic. We are trying to scale images and reproduce this smooth scaling. Does anyone know how they do it? We don't know if it's a single

How to detect Swipe and Tap in onTouch method? I want one of two actions to be executed when I swipe and other when I just tap. Need to know how to dell the difference between tap and swipe. Here is my code: @Override public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_MOVE) { mGestureDetector.onTouchEvent(event); } switch(event.getAction()) { case MotionEvent.ACTION_DOWN: x1 = event.getX(); y1 = event.getY(); break; case MotionEvent.ACTION_UP: x2 = event.getX(); y2 = event.getY(); float deltaX = x2 - x1; float deltaY = y2 - y1; if (Math.abs(deltaX)

I noticed that when I swipe my finger from left to right across a home screen widget, in simulator on a AVD, Android switch to the left home screen. I was wondering if its possible to prevent this behavior and allow home screen gadgets to listen and react to finger gestures (like swipe)? Its very critical for my widget UI design. Starting with API level 11 (Android 3.0.x) you can use " android.widget.RemoteViewsService.RemoteViewsFactory " and and assign a widget to use (from docs): ListView : A view that shows items in a vertically scrolling list. For an example, see the Gmail app widget.

I have done quite a bit with gesture recognizers for iOS, but I am now doing work in OS X, and I am lost. I want to duplicate the functionality that exists like in Finder where you can two-finger swipe (on your magic mouse) to go back/forward through a directory tree. I have an NSWindow based app that looks very similar to Finder. I have used apps before that allows you to build your own gesture recognizers so I know it is possible to do it, but I don't see any documentation on it. What do I need to do to implement these gestures? You can read about Handling Trackpad Events in the Cocoa Event

I am reading the gesture in android at android developer, and following the tutorial I tried to run the following codes: public class MainActivity extends Activity implements OnGestureListener, OnDoubleTapListener { private static final String DEBUG_TAG = "Gestures"; private GestureDetectorCompat mDetector; // Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); View v = new RelativeLayout(this); v.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); setContentView(v);
