Can't get touch event detected on a view and click event detected on a parent view

由 混江龙づ霸主 提交于 2019-12-08 08:37:35
问题 I've got a layout 'layout_base' that fills the screen and a child view 'home'. I set an OnClickListener on the 'layout_base' to do some action (close a popup if it's open), and an OnTouchListener on 'home' to do some other action (translate on fling). My issue is that I can only get the action done if I return true in the onTouch method of the 'home' touch listener. If I return false , onFling is not called. Why? From the doc I've read that this only mean that the event is consumed, i.e. from

Swift - Rotate gesture and rotation increments of 90 degrees

由 老子叫甜甜 提交于 2019-12-08 08:37:12
问题 I have a rotateView setup with a UIRotationGestureRecognizer . Works as intended, however I would like to only rotate in notches/increments of 90 degrees. The default behavior allows you to be very granular and precise with the rotation. I want it to be the opposite, of only 4 possible positions. The code I have below is as close I could get, however the problem I am facing is the rotation only happens once, and only to one direction (rotates to the right, even if I 2-fingers rotate to the

Image zoom activity for android

由 徘徊边缘 提交于 2019-12-08 08:32:54
问题 I'm trying to implement the double tap and the pinch to zoom activity. I wrote some code for the first one but it seem not to work (i can use only the android emulator for eclipse for now. So I'm not sure if my result is the right one) Anyway I'm not able to understand what am I doing wrong. I'm surely forgetting something. This is my code: public class ImageZoomView extends View implements OnGestureListener { private static final int SCALING_FACTOR = 50; private final int LANDSCAPE = 1;

Kinect Grip Gesture for Click

由 自作多情 提交于 2019-12-08 01:46:43
问题 I'm using kinect V2.0. I need to perform click using grip gesture. Is there a way to handle the Grip gesture in V2.0 like AddHandPointerGripHandler in V1.8. 回答1: In Microsoft Kinect SDK v2.0, the Body class includes two properties: Body.HandRightState Body.HandLeftState Both these properties are instances of the HandState enumeration, which specifies if the hand is: Closed (and you can detect this to trigger the Grip gesture); Lasso (which means that the hand is closed in a fist, except for a

In Flutter, how can a positioned Widget feel taps outside of its parent Stack area?

由 你。 提交于 2019-12-08 01:03:47
问题 A Stack contains MyWidget inside of a Positioned . Stack( overflow: Overflow.visible, children: [ Positioned( top: 0.0, left: 0.0, child: MyWidget(), )], ); Since overflow is Overflow.visible and MyWidget is larger than the Stack , it displays outside of the Stack , which is what I want. However, I can't tap in the area of MyWidget which is outside of the Stack area. It simply ignores the tap there. How can I make sure MyWidget accepts gestures there? 回答1: This behavior occurs because the
