I 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 am looking for a tutorial that explains the logic for fast, robust location finding.Basically I am sick of Google Maps finding my location so incredibly fast and accurately while my own application struggles to get a location.I would be fine with pseudo code responses and I will explain what I am doing so maybe I can be shown what I am doing wrong.
1. Get the locationManager object.
2. Do a 'get best provider' call.
3. Get a list of all available providers.
4. lm.requestLocationUpdates(bestProvider, 0, 0, this); hit the location provider as much as I can to get my first signal
5. Send a delayed message.If a location cannot be found in 10 seconds, switch to a different provider and try again with lm.requestLocationUpdates(nextProvider, 0, 0, this);
6. Repeat step 5 until I have a location.
7. Once a location is found determine if it is the most accurate provider.If it is not try again with the most accurate provider on an 8 second delay.If it is the most accurate provider then set lm.requestLocationUpdates(currentProvider, 30000, 0, this); to conserve battery
8. Make sure to lm.removeUpdates(this); before changing the requestLocationUpdates
Now it occurs to me that it may be possible to iterate through my list of providers and do requestLocationUpdates for all providers at once.Is this a viable option or can you only listen to one provider at a time?I have seen that location from onLocationChanged has getProvider()to let you know who provided the location information so that I can know which provider is actually finding a signal and turn off the others.
I'd like to announce the release on the Android Market of our last creation: 1 Minute Game. The main concept is very simple. The computer shows puzzles based on numbers, shapes and colours: the player must solve them and touch the correct answer to go to the next round, trying to be as fast as possible. We implemented 3 different modes that must be unlocked by playing more and more. You can play games under the "Training" areas so to train yourself and challenge your friends locally (there are 6 slots to store the profiles of the players).
Online Challenge
But the core of 1 Minute Game is the online challenge, which allows the players (once per day) to play a special match and to send the result to an online leader board. Each score shows also the nationality selected by each player try to get your country at top of the ranking. The ranking is visible both through the application and visiting the web site of the game.
Free DLC
In order to make the game more appealing and let you enjoy it for more time, we are developing new games to be released for free in the next versions of the application. For example, this morning (it's a matter of minutes) we will release the version 1.1 which contains a brand new game in the training section: The intruder. In each round, all of the objects shown on the screen share the same characteristic (same shape, colour, number or animation) except for one: that's the Intruder!
New games of logic will be released once they are completed and fully tested through future news.
LITE version
There is also a LITE version in the Market: 1 Minute Game LITE (limited number of levels, no online challenge and 2 slots to store the users' profiles), so you can try it and see if it is worth to buy the Full one. This LITE version includes the additional training "The Intruder" as well.
DOWNLOAD
the game can be downloaded from the Android Market. Just search for its name or click on these links with the browser of your Android smartphone:
FULL version - market://search?q=pname:com.wepromite.oneminutegame
LITE version - market://search?q=pname:com.wepromite.oneminutegamelite
I am calling a PreferenceActivity from another activity and then updating the application state (ie: changing the font size) on onActivityResult, based on the preference changes. I was thinking it would be better to put the state update logic in the PreferenceActivity. That way I don't have the duplicate the logic in each activity that calls the PreferenceActivity. What's the best or correct way to do this?
View 2 Replies View RelatedI know this is more of a general programming question, but my Android friends here have always been helpful. I am trying to make an image move from one part of the screen to a position the user touches, as a constant speed. I don't know the best way to go about doing this and the way I have been trying to get to work is taxing my brain too much.
I have been using geometry to calculate slope, then using Sin * movement speed to calculate the difference in X,Y coordinates.
This is the codecode...
The problem that I'm having is the image is veering way of course when traveling in Y heavy paths. When traveling horizontally it works almost perfect.
I know there is probably an easier way though I don't know how to use a lot of things (like OpenGLES) so if your advice is to use a different method please link a tutorial for that method if you know of one.
Now I have (1: the UI-loop, there my SurfaceView is placed), (2: a second thread, there the draw function from the UI-loop is called AND the update calculations from my Engine) and (3: the engine, there all the calculations stuff are).Now I wonder how the best and smoothest way to do the SurfaceView independent from the actual frame rate. How shall I do so it will compensate if there is a low frame rate?
View 2 Replies View RelatedI've read the article "Supporting Multiple Screen" on Android developers site. But that doesn't apply to game logic.Let me get straight to the point. My situation is as follows:
- I'm creating a game using LunarLander code as a base.
- In my game, there'll be an object flying up from the bottom of the screen. The object will fly in projectile motion.
- I set the starting velocity, gravity and angle so that the highest point(of projectile motion) is almost at the top of the screen.
- The screen tested is Motorola Milestone. (480x854 resolution) Meaning the object travels around 854 pixels vertically.
I'm thinking of adjusting starting velocity based on screensizes. But that sounds unreliable when we've so many devices/resolutions out there. How do you combat these kind of problem when making games?
My stats:
LG L35g Optimus Logic from Net10
Running Android 2.3.6
It is rooted.
Clockworkmod 5.8.4.5
Okay, first off this is totally my fault that this phone is stuck.
I was inside the About menu of android and saw there was an update for 2.3.6
So, stupidly, I decided to select it. It downloaded the update, rebooted, and then wound up at the clockworkmod recovery screen.
I tried the "reboot system now" option, but it just reboots back to the recovery screen.
I have used the "wiped data/factory reset" option. I've wiped the cache partition and Dalvik cache.
I didn't backup the stock rom, so I found these two roms for the l35g from here:
AA51
Stock (user modded version)
I used the restore option in recovery mode, but the "Stock" rom above didn't take. The AA51 rom did install fully and told me to reboot. I did, but it still went right back into the boot-loop!
I think the solution to this is to fix the boot-loop issue. Would Zengarden or Xionia work? Then, if so, I need a version of it to work with the l35g.
Can't get actions like: # android.wallpaper.tap # android.home.drop
I tried on Cube Wallpaper example by adding to CubeEngine class:
@Override public Bundle onCommand(String action, int x, int y, int z,
Bundle extras, boolean resultRequested) {
System.out.println("action" + action);
return super.onCommand(action, x, y, z, extras, resultRequested);}
No actions happens by tapping dropping and etc.
I am displaying google map and on top of that some overlay items(Markers) are there. When tapping on the markers, I need to display PopUpWindow. The code is executing but popup is not displaying.
popUp.showAtLocation(layout, Gravity.TOP, 0, 0); popUp.setFocusable(true); popUp.setTouchable(true); popUp.setOutsideTouchable(false); popUp.update(0,50, 320, 70);
Here layout is an object of LinearLayout.
I created another android application, in that, I put the above code and its working perfectly. PopupWindow is displaying.
I am writing an Android App where I am playing video using VideoView,but the mediaController appears only after tapping the screen.Is this correct procedure ? If not how can we make it to appear without tapping on the screen.
View 2 Replies View RelatedSurprisingly, I don't seem to have issues with the OpenGL side of things (which is very unusual), but my problems stem from getting a clear idea for app architecture and a few other problems. Right now, most tutorials on the net just describe the render portion. I know that when I create a GLSurfaceView and hook a Renderer into it, it uses it's own thread for rendering.
I want to do logic operations and other gameplay stuff (like moving characters and whatnot) in it's own thread as well. Can anyone explain a good approach to this? I'm guessing the two threads will have to be synchronized (do logic, render, repeat), and limited based on time so that it performs smoothly across different devices.
when a "contact detail" screen is presented in the contacts application, how is each field aggregated from its underlying raw contacts
case 1: Overlapping fields
when the same field exists in two or more contacts. Say they have two different last names or emails in different accounts. Does the contacts app show both fields with an account indicator?
case 2: Non overlapping fileds
one rawcontact has email while the other one has phone number
Short of scouring the source code, I have exhausted searching everywhere else.
Is there a way to go to the top of a page in Chrome, by using a single tap? In iOS Safari this can be done by tapping on the top bar. The page will go to the top immediately. With Chrome I have to manually scroll up to the top of a page.
Actually the question is not only about Chrome, it's about Android in general. How can I have this functionality in the Mail.app for example? I have only seen that in the Blinkfeed of the HTC One M8 only.
Is it normal, when you double-tap on a website to zoom in, for the zoomed in portion to be nowhere near where you tapped?
I assumed that wherever you tapped, it zoomed in to that spot, but often it doesn't do that for me. Instead it might end up halfway up or down the page. Is that normal? It just happened on Wikipedia.
I'm using the stock browser.
how come when I tap the screen to take a picture it is very inconsistent as far as when it will take and when it doesn't. Any advice?
View 2 Replies View RelatedI would love a music app that could be controlled with the phone still in my pocket. Sometimes I'm working in the yard with gloves on, dirty, sweaty, and the last thing I want to do is take my glove off, pull the phone out of my pocket and get it dirty while trying to skip. I know there are headphones w/controls but that would still be tough with gloves. Tapping would be awesome.
Something like:
One tap for pause
Two for play
Three for next song
etc
Maybe even use hard or soft taps. Or tap-wait-tap to avoid controlling it by accidental bumps.
Anything out there like this? Is it even possible to write an app that does this?

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?
So despite my gut feeling I took off the film behind the screen as the other thread indicated.Now my phone slides smoother but when it is closed and using it in portrait view, the bottom and top left of the phone makes a tapping noise everytime I press there. It's really annoying specially when I'm typing something or going back and I keep hearing tap tap silent silent silent tap tap tap.As I took a closer look, it seems like the legs on the left side on the back of the screen don't quite reach the keyboard base, therefore creating a gap and tapping the keyboard base whenever i press there.Has this happened to yours too? If so, do you have the film in the back or have you taken it off?

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 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 use Google Calendar to organize my life, and rely on the email reminders to keep me from forgetting events and to know when to act on them. With 2.1 I had no issues, Google Calendar was synced to the stock HTC calendar app on EVO. I had the calendar set to view in "agenda" mode. Now since updating to Froyo, when I open the calendar app in agenda mode, the events have bell icons to the right of them, this is new. If I tap the event to open it and view the details of the event, when I return to the main agenda viewing mode of the calendar the bell is gone.
The phone then syncs with Google Calendar, and deletes all of the scheduled Email Reminders that I have set up for the event. This was not a problem with 2.1. No bells showed to the right of the events in agenda mode, and I could tap into the event to view the details without deleting email reminders on Google Calendar. With Froyo, by simply tapping the event to view the details it is effectively wiping out all reminders, rendering the calendar useless. This making me wish I had never updated to Froyo. The calendar and reminders are the single most important function on my phone, and with Froyo it seems to be incredibly flawed.
I find the full size keyboard keys too small so I've reverted to the Phone Keypad setting. The query is how do I select a letter when the next letter I want is on the same key (Eg. Letter m and o in quick succession). Without pausing or selecting it from the menu?

Is there anyway to set double tapping the home key to turn on bluetooth? I like to leave it off until I get a call. It is very annoying to have to go back to the homescreen to turn it on. And I think the bluetooth button on the call screen should turn it on if u press it but it just shows you if its connected.
