I 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 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?

In 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 was using my phone (droid 3) and the app I was using force closed, my phone lagged for a few seconds and then I just put it down so it could catch up. While waiting the screen timed out and when I went to use it I could not unlock it. I can press the button on top and it will turn the screen on or off, and if I hold it it will bring up the power off menu. I tried to call it, and it went through. I got the normal screen to answer it, but I could not answer it. After I hung up I got the notification for a missed call. Everything seems to be working, my screen just does not respond to a touch. What should I do?
View 4 Replies View RelatedI'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 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?

I was wondering if there was one solution that would work for websites on both the iPhone and an Android phone.
In the Android API examples there is a Snake game. This game uses a class called SnakeView, which inherits from TileView.
I am doing something very similar to this. I am inheriting from TileView to create a class (SkyView), which will become a square board for a board game (similar to the board for Checkers).
However, I would like for my game board to be 400x400 pixels in size, which will be bigger than the screens of some Android devices (such as the G1). And I would like for the user to be able to freely scroll and drag the board around with their finger (both horizontal and vertical scrolling/dragging).
Can someone please point me in the correct direction for implementing this? The board must be no smaller than 400x400px in size. And however much of the board that can be displayed at once on the screen, should be displayed at once.
Should I wrap my SkyView widget in an AbsoluteLayout and use Scrollbars? If so, what Scrollbar properties to I need to use? I played around with Scrollbars in both directions but couldn't get it to work. Is there another view layout I should put it inside? Code examples would be nice! Thanks for the help. I am at a loss with this one.
Last night i noticed a thin crack on my screen about an inch long. You cant feel the scratch on the outside. This morning the screen had gone really dull an cloudy and is basically fudged, you can hardly make anything out. I hav'nt dropped it so can only think there must have been some sort of pressure on it.
My question is what are my options?
I am about 5 months into my contract with vodafone and dont have insurance with them.
Would this be covered by the warranty?
My other option is obviously to pay for a repair if thats possible?
Or maybe claim it on my house insurance.
I have a custom view i am writing for my drawing app but the first time i set the drawing into it i need to get the dimension for the view (using getMeasuredWidth() & getMeasuredHeight()). But until the view display these return 0. I have tried calling: requestLayout() invalidate() numDraw.measure(MeasureSpec.EXACTLY, MeasureSpec.EXACTLY); but nothing seems to force the values to update.I guess the question i am asking is : does anyone have any tips on how to get view to update its measurements off screen?

View 1 Replies View RelatedRight now all I am trying to do is detect when the screen is pressed and then display a log message to confirm it happened. My code so far is modified off of the CameraPreview sample code (it will eventually take a picture) so the bulk of the code is in a class that extends SurfaceView. API for the example code from the SDK is 7.

Is it possible to detect all touch events in an Activity and capture it and then in return pass that pass event to another View. For example:
Button 1 and Button 2. When Button 1 is pressed I want to capture that touch/click event and automatically pass that touch event to Button 2, basically with one touch/press you get the click generated and that same click is passed on to the second button automatically.
I want to figure out how to detect that the user has been doing a long touch press on the screen? Most of the solutions that I see assume that the DOWN + UP sequence of events.
View 2 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?

View 3 Replies View RelatedI found event handler: dispatchTouchEvent(MotionEvent) works differently between G1 & emulator when finger is holding on touch screen.
I have a class inherited from RelativeLayout and override public boolean dispatchTouchEvent(MotionEvent event) method. After I touch & hold on the touch screen, in emulator I got MotionEvent.ACTION_DOWN event only. But in G1, I got MotionEvent.ACTION_DOWN first and then MotionEvent.ACTION_MOVE continuously, even if I try my best to hold still my finger tip.
I wonder if this is because there is pressure field in the MotionEvent. Because the blood pressure on finger tip changes continuously with heart beat, so no matter how still my finger is, the pressure value still changes. But I wonder if all kinds of touch screen have pressure factor in their touch event? Will all touch screen driver emit touch event continuously when finger is holding on the screen?
Just a quick question about the Captivate. I just got myself an HTC Aria and I love how easy it is to use the touch screen on it. Its extremely responsive. Now my sister has the SamSung Instinct on Sprint and the touch screen is horrible compared to HTCs touch on the Aria. Im thinking about taking the HTC back to AT&T and getting the Samsung Captivate. I am just worried about the touch screen on it and if it will be like the Instincts? If the touch is as good as HTCs Ill get it. If its not, then Ill stick with the Aria because despite its size, its an extremely fun and responsive phone. Any thoughts?

I've noticed that I'm getting little tingling shocks to my right index finger whenever I touch the Evo's screen.What's even stranger is that I don't feel the sensation on any other fingers on either hand. Has anyone else had a similar experience with their evo screen and finger feeling little shocks?I'm not imagining this, and I'm wondering why the heck it's just my index finger?!? Maybe it's just more sensitive, but who knows.I would assume that the capacitive touchscreen technology is the culprit. I can live with the slight tingling, I just don't know why it's only on 1 finger!
