问题 I’ve written a little example page with elements that are draggable on touch devices (based on code by Peter-Paul Koch). My example page I have two draggable <div> elements: a green block, and a red ball (made ball-shaped with border-radius ). The dragging is implemented with ontouchstart , ontouchmove and ontouchend , and the "animation" is done by changing the top and left CSS properties of these elements. When I drag the green one, all is roses and ponycorns. But when I drag the red one in

WebDriver simulate touch events in Desktop Browser

I'm trying to simulate some touch events like swap, tap in web-based application using Chrome and Firefox browsers. I've tried to simulate touch events with Actions , Hummber.js , " Yahoo " lib(YUI) but none of them works for me. What is the best way to simulate touch events with webdriver in desktop browsers? I'm using phantom limb which transforms mouse events to touch events. It worked for me. I thing the best way to simulate touch events in Chrome is to use built-in emulations mechanism. Like in this article. Unfortunately I can't find the way to turn on this feature by webdriver. Found

Drawing a line following finger - motionevent.getX() and getY() incorrect UPDATE

问题 UPDATE: please read entire question again :-) Background: I have created a grid of dots by creating a custom view and then adding these views to a TableLayout . The aim is for me to be able to draw a line from one of these dots to another dot in a way so that when a dot is pressed, a line is started from the center of the pressed dot to the point where the finger is currently touching. When the finger is dragged over another dot, the line then finishes at the center of that dot. The result

问题 I'm playing with touchstart and touchend events on my iPhone.

Misplaced clickable area due to class toggle / height change on touch event

问题 There's a strange behavior on touch devices regarding the clickable area of a link, if you toggle the height of an element placed above. If you run the following snippet (e.g. save it locally and use chrome to emulate touch events), you will notice that the hash #mylink is added to the url in some cases you did not click on the red link area. And sometimes you clicked the red area, it won't be added. E.g. If you click the upper grey area (first 200px), the grey area toggles the height. => Ok.

问题 i'm making my first 2d sidescroller game using a surfaceview and a canvas to draw things on (a lot of primitives put in different path objects). my game loop uses fixed timesteps with linear interpolation. i don't create any objects during the game. i've been improving my code for 3 weeks now, but my animation is still not all the time smooth. it's ok, but every few seconds there are a lot of little hicks for about 1 or 2 seconds. what i recognized is when i move my player (this means

Simulating touches onto an activity of another application

由 若如初见. 提交于 2019-12-08 08:22:58
问题 Is it possible to simulate touch events in Android from one app to another app? Perhaps use a service or an invisible activity with SYSTEM_ALERT property to receive the input touches then simulate them to another activity of another application which is directly below the transparent activity of your application. Is this possible? [UPDATE] Taking FoamyGuy's answer into account, is it possible to have an invisible SYSTEM_ALERT activity to filter out certain touch events? I know you can revoke
