How can you detect that a user swiped his finger in some direction over a web page with JavaScript?
I was wondering if there was one solution that would work for websites on both the iPhone and an Android phone.

How do you detect a horizontal or vertical finger swipe?
View 3 Replies View RelatedI have a motion listener to detect finger down, finger drag, and finger up. I start my action at finger down and finish my action at finger up. When the action is finished, I store it in a stack for allowing undo. My problem is that if I don't get a finger up event, I can't finish my action to add it to the stack for undo.
How can I detect that the user's finger has left the screen?
I tried using the emulator to see if getEdgeFlags() ever returned anything useful, and the result was always 0.
Basically, if a finger leaves the screen, then nothing is touching the screen anymore and I would like to detect that as a finger up event. How can I do this?
I've got a view where I override onTouchEvent to detect touching the view with a finger and also to detect lifting the finger from the view. I'm getting the ACTION_DOWN event but not the ACTION_UP event. In fact, onTouchEvent isn't getting called when I life my finger. Could it be that the finger-down and then finger-up is considered a click event and so onTouchEvent is not called? If so, what use is ACTION_UP?

View 1 Replies View RelatedIn Javascript/jQuery, how can I detect if the client device has a mouse?
I've got a site that slides up a little info panel when the user hovers their mouse over an item. I'm using jQuery.hoverIntent to detect the hover, but this obviously doesn't work on touchscreen devices like iPhone/iPad/Android. So on those devices I'd like to revert to tap to show the info panel.
I'm not highly familiar with javascript but I think this is the best way to accomplish my purpose. If not, please correct me. I have a licence text 2 buttons at the end. All of this is written in HTML in a WebView because there are some links in the licence. Now, I want that when the user clicks the "ok" button in the WebView, this triggers some javascript or listener that I can grab in Java to fire an Intent to go forward in the application. (The cancel button would do the opposite, but if I know how to do one, I can do the other. Does this rings any bell to someone? Any explanation or sample code is welcome.
View 1 Replies View RelatedI would like to get access to the area covered by a finger for each touch event on an Android.Every touch event will result in a coordinate pair X and Y independent of how big the finger and consequently the touch area is that triggered the event. I was wondering if there is a way to get the area data which triggered the touch event e.g. size or coordinates NOT

View 1 Replies View RelatedI have built a website for mobile webkit browsers, there is an interval update to refresh data. But it turns out that the pooling refresh will stop at some time after run for a while (some minutes or hours, different by each time).I thought there may be something error occurred in my refresh data functions, but it works well in my laptop browser. I also tried to listen window.onerror event, but webkit browser seems do not support that event. What else can I do?And I am also doubting is there any problem with setTimeout and setInterval functions in mobile webkit browser?
View 1 Replies View RelatedWondering here if there is a way I could trigger an event, so that any library listening for these events (e.g. jQTouch, Sencha touch, iUI, ... ).
If I could extend or use jQuery for such task e.g. $(...).trigger('event') that would be great to know.
Usage example:
I need to debug a few web apps by simulating multi touch with my mouse. This seems a little complicated, so if I could trigger the multi-touch events using Javascript I could therefore test the app more efficiently.
Is it possible to detect that the viewport is being dragged by a touch event?
Using the following code I am able to get the position of where the finger touched the screen, what node started the event and where it was dragged to. Which solves one of the problems but I would really like to detect when the user has dragged the page/window/viewport down.
To attempt to be more clear as to what I am trying to do: I would like simulate the refresh activity in Tweetie 2/Twitter for iPhone but in HTML5 and JavaScript. Code....
Update: According to posters below it doesn't work on their fascinate. You can control the screen brightness, by swiping right or left, up where the notification bar is. if it doesn't work, try turning off power saving mode. settings>sound and display>power saving mode uncheck

View 12 Replies View RelatedI understand calling onTouchEvent from views to get the location of the last touch as a motion event. How the heck can I tell that a figure is down on the screen and has not been lifted and when the finger is lifted?
For instance there is onKeyDown and onKeyUp for use when you are dealing with keyboard input. So how can I find out when on fingureUp happens?
I can't find a tutorial on Google for my problem. I'm french and i don't find the best "google keywords" for to describe my goal. I decided to ask the question here.
I want to do an animation between views like on the Home or on the Calendar in week mode. I want the switch between the views follows the finger. As I have not released the pressure, I see a part of the current view an a part of the next view.
Currently, I use a AnimatorView and 2 gestures. But the change happens when the pressure is released, and it's not good.
Can someone explain to me how to do or where to find a tutorial that explain? ps : please, don't laugh about my english, it's worst when I speak with my very french accent :P
I'm adding 5 ImageView to an linear layout at runtime, so far so good, but what i would like to do is, when the user slide his finger over one of them, i would like to change the image, so my question would be, how can i know what's the current imageview under the user finger.?
View 2 Replies View RelatedI was checking the possibility to allow painting on the screen of a surface (i.e. API demo Fingerpainting example), however when I checked it, this technic apparently only allows painting with the tip of your finger, if you try to use any other object (pencil, thick pen, etc.) it does not draw anything on the surface. Am I missing something here? Is there a way to allow other objects to draw things on a surface? Is this achievable and how should I proceed?

View 1 Replies View RelatedI have a ListView. When I click a row Item (which are just TextView instances) I want them to remain hilighted (default orange color). The default behavior is that they flash orange.
Strangely, if I use the key pad (arrow up/down) to move between items, it has the exact behavior I want. Why is the logic different between using the keypad or with finger tapping?
I'm just getting started with mobile development, and after considerable searching I'm still confused about sending a message from my iPhone to another or an Android.For instance, in building a simple Tic-Tac-Toe game, if I want to notify the other phone of a move, what is the best way to do so? Wifi, bluetooth, 3G? And how? Many methods seem to point to communicating through a web server, but I'd rather send them directly from phone to phone if possible.

View 3 Replies View RelatedI want to create an event to change what my image button looks like, but only when it is being pushed down. So far I have been using an onTouch listener, but that just changes it permanently. I can't find anything like an onKyeUpListener() type of thing for the button.
Does anything like this exist? code...
I am designing a Game and have a large background. The background it a lot bigger than the phone display so the user will only have a small "View" of the background. They will be able to move around by scrolling with their finger.
How do i go about this?

I'm having a conceptual problem with a simple application.

If I apply:
