As title, i need a function that returns the pixel that i'm touching...
for example i have an image in background and i want that, if i keep touching a point for a little bit, it appears a menu where i can do something on that exact position like adding a draw on the picture in background...
already exists a function like that?

I have some png files that I am applying a color to. The color changes depending on a user selection. I change the color via 3 RGB values set from another method. The png files are a random shape with full transparency outside the shape. I don't want to modify the transparency, only the RGB value. Currently, I'm setting the RGB values pixel by pixel (see code below).I've come to realize this is incredibly slow and possibly just not efficient enough do in an application. Is there a better way I could do this? Here is what I am currently doing. You can see that the pixel array is enormous for an image that takes up a decent part of the screen
View 1 Replies View RelatedI have a single bitmap with several individual pictures in (each one is an option) and I would like to detect when the user touches these pictures. I am using the event.getX and event.getY to detect where is pressed, I know the top left X Y and bottom right location of each of the pictures. What is the best way of detecting which one is pressed? (i.e. tieing up the event press and which picture has been pressed?

View 1 Replies View RelatedI have a ListView that is populated with a custom adapter. When an item is clicked with the trackball, it works fine, i.e. I can catch the event and move on, though when I touch an item with my finger there is no callback from the listener.The item does respond to the touch, by turning orange for that moment.What am I missing? Is there another listener I need to configure?
View 11 Replies View RelatedI am experiencing a problem with my app. The 1st screen that appears is a map that displays pins that are located based on an XML file that is loaded from our server.
Sometimes the app loads as expected. Other times, the map loads but none of the pins appear until you touch the screen.
This may be an Android 4.4 or Nexus 4 problem, but I suspect the former. I encrypted the device (using the in-built encryption stuff) and have found that now the touchscreen will only register if another part of it is touched. For example, when entering my PIN once I get into the OS itself, I have to hold down a finger somewhere else on the screen (usually having to move it between some of the later numbers).
When it comes to multi-touch features (zooming etc.), these work fine but still require another finger held down somewhere to work.
This is definitely a software problem as the touchscreen works fine when putting in the password to decrypt storage.
Is this supposed to happen - part of the encryption process - or is this a bug?
I've got a ListView that works just great, except for this minor annoyance. I can use the trackball/dpad to move up and down my list, and the background changes according to which row has focus. But when I touch the row (click or long click), there's no background change letting me know what's been focused. I've tried setting 'focusable' and 'focusable in touch mode' to true on the rows, but it still doesn't work.
Just in case it matters somehow:
I am setting onClickListeners for each row. The row is comprised of LinearLayouts, TextViews, and a single ImageView. Focusable/clickable is 'true' for each row. Have not specified values for these on the ListView.
Trackable does act funny. I can only move between rows after touching inside the ListView. If I scroll trackball above the first item, it's impossible for me to scroll back into the list.
Ever since I bought my hero in December, I have had this problem where if I'm in a game, and it requires the screen to be touched, the game stutters. This happened when I had the stock 1.5. I needed to trade my hero for another when a lot of dust showed up under the screen, so Sprint gave me another one, only this one worked perfectly. No stuttering at all. So I decide to root it, and now it's running Aloysius, and the stuttering is back. Does anyone know what could be causing this? It happens in both the official and unofficial firmware. I can't seem to find an answer anywhere. Games it does this in includes: Nesoid and snesoid, and Raging Thunder to name a few. These games worked perfectly to my shock when I got the new phone, as I originally thought it was just a hero problem. I even emailed the developer of Nesoid but he didn't know the cause. Any suggestions?

On Aug 10, 2010 I purchased an unlocked HTC Legend (A6365 - HSPA 850/1900/2100 Mhz). The phone operated wonderfully until Sep 8, 2010. At that time, the Notification bar couldn't be "pulled-down" anymore. Additionally, without rhyme or reason, when I touch the screen, the notification panel will open randomly. This renders the phone useless since every time I touch the screen, the notification panels opens. I tried a softboot and a factory reset. Neither action resolved the issue. I contacted HTC USA support and they suggested clearing the calendar data and vigorously rubbing my hands together and then touch the screen whenever the issue occurred. No success. This issue occurs whether the SIM card is installed or not. I can safely say that no new applications were installed within 48 hours of the issue starting.
I search the available forums and found at least three other instances of this same issue:
http://www.htclegendforum.com/htc-legend-troubleshooting/touchscreen-bug/
http://www.htcforums.com/legend/5838-touchscreen-bug.html
http://androidforums.com/htc-legend/153561-notification-area-swipedown-not-working.html
Regrettably, none of these threads have any answers. HTC support then recommended for me to contact HTC Return Merchandise Authorization & Repair Center. This group (in the USA) cannot accept the phone for troubleshooting because this phone is not available in the USA. Based on the behavior thus far, I suspect this is an issue with the firmware becoming unstable. The phone hasn't been exposed to any drastic environmental changes (heat, cold, excessive dust, etc).
Software info follows:
Firmware version: 2.1-update 1
Baseband version: 47.37.35.09U_7.09.35.05
Kernel version: 2.6.29-9e497c43
Build number: 2.02.666.3 CL1777708 release-keys
Software number: 2.02.666.3
Browser version: WebKit 3.1
By know, HTC should have received multiple complains of this issue and I hope they have a solution for it. The options of the phone are great, reception is wonderful and performance is superb (except for this issue).
When I'm generally sending an SMS or using the text pad, there is a hepatic response which is welcome in my opinion. However when dialing, I don't get any vibration feedback. I swear remembering this was so

How do I use gl.gluUnproject in my OpenGL ES 1.1 android app to determine what is selected when the user touches the screen?

I was able to flash ROM from : LNK1 but I have a problem with touchscreen which works upside down. When I press screen on top it actually shows that I pressed at bottom of screen. I was looking for solution many days and have learned a lot from many sites and different forum threads, but surprisingly non of the solution works for me. I am not able to reach proper file to change proper property to change this behavior. Most probably i need to set somewhere: ctp_revert_y_flag = 1 as described here: LNK2, but I am not able to find nor edit script.bin on my phone, here I found some info: LNK3 and also here is very interesting info about partitions: LNK4 but I can't find this script.bin on my phone.
My phone is china phone 1:1 Real MTL 6589 GT-I9500, I was able to flash several ROM's using SP Flash tool from LNK5, I know how to do this, but no matter which ROM I flash no matter which recovery image I flash this touch screen behavior is still upside down as described.
1. set ctp_revert_y_flag = 1 in script.bin on my phone - I can't mount proper partition, don't know which partition should I mount, can't find this file
2. set ctp_revert_y_flag = 1 in script.bin on ROM file before flashing - don't know where to look for this file and don't know how to edit ROM before flashing.
What I know: how to root my phone, how to get to it using adb, how to use android-sdk, how to flash using SP flash tools, how to use recovery mode, clean user data, how to use SP Flash tool, how to switch on developer mode, switch on USB debugging, switch on "show touches".
I got my evo last Friday and I have noticed a dead pixel. It's on the e key when the keyboard is up and can only be seen on a white screen. My question is should I exchange it or is one dead pixel nothing to worry about? It looks like a little purple or red speck.
View 24 Replies View RelatedSo when I bought the Evo, the first unit had a crack on the bottom of the LCD, then I got a replacement that same day and it had a dead pixel. Sprint said they couldn't exchange three in one day, so they said they will call me when my replacement unit comes in, but I want to know if there is anyway to fix this one dead pixel?
This is a dead pixel, not a stuck one. I can only see it on a white background and its a black dot. Any thoughts?
I'm not even concerned with the camera per se. I want at the closest thing to the display screen. Meaning: it could even be the desktop the user is looking at, completw w/ the background and the icons she moves back and forth.
Let's say, at time t=1 sec, the app goes to pixel (78, 300) on that display and obtains its value. What may be at (78, 300) could be a portion of the icon or some speck of tree leaf on the photo being used as desktop background.
I'm familiar with BitmapFactory.decodeFile() for getting at the pixel contents of a file. But what about the display?
I am new to Android and OpenGL world. I've created a new ap using openGL ES. The package is attached with this mail. Android Simulator LCD size is 320 x 455 and i've set same size for OpenGL Viewport. But For creating visible rectangle i've to use vertices, which are of very high value.

It is small but it is annoying so I decided to phone up T-Mobile. Amazingly they have arranged for a swap to happen tomorrow. Can't fault them at all.
