Android :: Touch Screen Data

Jan 20, 2010

Alot of android phones use the capacitive touchscreen technology. I was wondering if there is away to access any sort of information related to this sensor.

In other words I want to get the voltage potential related to the distance that you push down on the screen.

I know this is probably really deep into the hardware technology and it's probably proprietary, but I want to know if someone has figured out how to access this data or if there is a way around it.

Android :: Get Raw Touch Screen Data

Oct 21, 2010

RT Actually I wanna detect the shape of touch point, i.e. the shape of finger touch on the screen

Seems that the only information I can get in touch event is the size of the touch point(by event.getSize())

By the implementation of the screen, the shape(and pressure of each point in the shape) of the touching finger should be the first raw data that the hardware can detect

So, how could I get these raw data?

Samsung Captivate :: Touch Screen Compared To HTC's Touch Screen?

Jul 17, 2010

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?

Motorola Droid :: Touch Screen Works On Half The Screen

Sep 11, 2010

I bought a new droid for $20 haha lucky i think until i notice that the touch screen only works for the middle of the screen to the left so if yu cut the screen into thirds only the middle and left work assuming that yu cut it from top to bottom with the lights at the bottom for the home button etc. I opened it up cleaned all the flex cable with alcohol and waited for it to dry and it still does the same thing so my question is = do i need a new digitizer or is it a software problem or something that i dont even know?

HTC Desire :: Locking The Screen Via Touch Screen

Jun 19, 2010

Anyone know of a widget to simply lock the screen or put into sleep mode by pressing something on the screen rather than pressing the power button on the top of the phone. Tried looking around and unless I'm missing something (I am particularly good at missing the obvious!) there doesn't seem to be anything that does just that. Anyone know/come across anything that will do this? Does anyone know if this might be included in 2.2?

Android :: Touch Screen Slowdown

Mar 26, 2009

I am having a problem with the touch screen in that whenever the screen is touched, it causes significant slowdown because of the large number of callbacks that are being made. I have read in this group about throttling the UI thread, but this does not seem a good solution and i can't believe there isn't a better approach?

Android :: Game / Touch Screen Controls

Feb 25, 2010

It would end up looking something like the PSP. You would think that this would be an incredible feature for gamers and any platform that was serious about gaming. Then we wouldn't have to use touchscreen controls, barely passable d-pads, or optical trackballs?

Android :: How To Get Screen All Dark But Still Touch Sensitive

Aug 23, 2010

I want to get the display as dark as possible but I also want the display to remain touch sensitive.So I can't turn the display off, otherwise it wouldn't react to touch anymore. And I use WindowManager. LayoutParams. screenBrightness to get the screen as dark as possible. And I put a layer colored black over the entire display.That works, but at night one sees that the screen is still quite strongly illuminated.Does anybody have an idea of how to get the screen even darker?

Android :: Touch Screen Response Delay

Feb 6, 2009

I am working on a game that displays its graphics through a modified SurfaceView.The game scrolls around a map based on the location of the main character.That all works fine.I am trying to add a feature to the game that allows you to touch the screen and drag the camera around to see other parts of the map.This is where I am running into trouble.The game's SurfaceView overrides 'public boolean onTouchEvent (MotionEvent event)'to call another method in the game's thread which handles the events.Sometimes, this works fine (although the frame rate drops significantly while the screen is touched).Other times, there will be a delay of several seconds before the game responds to a touch event, during which time the game continues, but the user loses all control.During these delays, a message sometimes appears stating that my activity is not responding, and giving the options to 'Force close' or 'Wait'.If the user selects 'Wait', the game almost always resumes right away, but these delays are obviously not acceptable.The delays occur only the first time the screen is touched after the game is started.Once the game has resumed after a delay, the touch events work just fine again.

Android :: Monkey - Touch Events Being Dispatched To The Screen

Sep 8, 2010

I start monkey like this:

monkey -p <MY PACKAGE> --port 4321

(I have already done a tcp port forwarding).

I then use PuTTY to telnet to 127.0.0.1:4321

I can issue a command like tap 100 100 I get a response OK but I see nothing happening on the UI. I have placed a button at that location but I does not receive the touch event.

When I run monkey like this

monkey -p <MY PACKAGE> --pct-touch 100 -v 10

I see touch events being dispatched to the screen.

Android :: Detect Touch Screen Devices With Javascript?

Oct 20, 2010

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.

HTC EVO 4G :: New Touch Screen

Apr 22, 2010

I'm actually usually lurking on the HTC Incredible forums, and had originally found a greatly informative article about the new touch screen tech the EVO 4g and Inc will be using.

Does anyone have a site book marked talking about how it's different, how it works, and how it compares to other screens? I know there was an article, and a video of a woman using the technology on a big screen, it looked great. I wanted to show it off...it really is some amazing technology.

HTC EVO 4G :: Touch Screen

May 2, 2010

My wife and I are looking at the Evo. It will be the first touch screen either one of us has owned. My wife has long finger nails. Will she get by with touching the screen with her nail or will she need to actually use her finger? This could be a deal breaker for her.
