gesture-recognition

I am developing an SOS android app. I want to detect a gesture (for example several touches on screen) if the phone is in mode sleep/standby, and start a send of help request (for example send a sms). How can I detect this gesture? Someone that can help me? Thank you ---SOLUTION---- I found the solution here and this is my code: 1)in the main activity getApplicationContext().startService(new Intent(this, UpdateService.class)); 2)I create a service public class UpdateService extends Service { @Override public void onCreate() { super.onCreate(); // register receiver that handles screen on and

I am trying to implement the OnGestureListener in Android. I have three TextViews in my layout. What i am trying to achieve is to set Gesture Listener for two of the textViews . Here is the layout - <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/rlMain" android:layout_width="wrap_content" android:layout_height="wrap_content" > <TextView android:id="@+id/tvOne" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_marginBottom="10dp" android:layout_marginTop="5dp" android:gravity

My goal is to recognize simple gestures from accelerometers mounted on a sun spot. A gesture could be as simple as rotating the device or moving the device in several different motions. The device currently only has accelerometers but we are considering adding gyroscopes if it would make it easier/more accurate. Does anyone have recommendations for how to do this? Any available libraries in Java? Sample projects you recommend I check out? Papers you recommend? The sun spot is a Java platform to help you make quick prototypes of systems. It is programmed using Java and can relay commands back

I have gone through the documentation: https://web.archive.org/web/20130309051214/http://developer.apple.com/library/ios/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/GestureRecognizer_basics/GestureRecognizer_basics.html#//apple_ref/doc/uid/TP40009541-CH2-SW2 I am trying to implement the check mark example shown in the documentation and I can't because the compiler shows a bunch of warnings about the [super touchesMoved:touches withEvent:event] call, which is recommended by the documentation. Where's the full example to learn how to correctly subclass for implementing a custom

I am trying to implement pinch zoom and drag using Android's gesture listener and scale listener. The problem is that when I perform pinch zoom, the image (which I am trying to zoom) bounces to a particular location. Also the zoom position is not centered. The following code demonstrates what I am trying to achieve. Any idea why the image is jumping (and how to correct it) ? public class CustomView extends View { Bitmap image; int screenHeight; int screenWidth; Paint paint; GestureDetector gestures; ScaleGestureDetector scaleGesture; float scale = 1.0f; float horizontalOffset, verticalOffset;

i need to detect direction of my swipe gesture and i've got problem with it. gesture is working, but i don't know how to detect direction. ... swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(detectSwipe:)]; [swipeGesture setNumberOfTouchesRequired:1]; [swipeGesture setDirection:UISwipeGestureRecognizerDirectionDown | UISwipeGestureRecognizerDirectionUp]; [appView addGestureRecognizer:swipeGesture]; -(void)detectSwipe:(UISwipeGestureRecognizer *)recognizer { switch (recognizer.direction) { case UISwipeGestureRecognizerDirectionUp: NSLog(@"smth1"); break;
