How do I reposition views at runtime? In activity onCreate when all views are set all views sizes are 0. If I could somehow subclass activity view loaded from resources I could probably override view's onFinishInflate() and reposition all views after they all have been set and inflated.

I have a case where I have add to listview textview based on no of messages.
1) I am doing like this for.
CODE:..............
I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?
I want to populate a table, defined in layout xml file through the programmatic way. I have define Table with a single row defining its header, with all the attributes set. Now i want to know a way so that i can just replicate that header row in the table with new content.
I tried using inflator inflate(int,view) method, but at runtime it showed up with error.
Here is the XML code for the layout file defining the table
CODE:.................
I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.
How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.
View 2 Replies View RelatedIs there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

I'm not asking how it's done in XML, which I do know, but rather, how can I do something along the lines of (One View).add(Another View) Like one can do in Swing.
View 2 Replies View RelatedMy calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:
Unable to parse response from server
Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.
I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.

View 1 Replies View Relatedat the moment I am thinking about a new app and need some information to decide whether to develop on Android or an alternative OS. I am particularly interested in "time to first screen", "boot-up time", "time to first Audio" and "app-start" (can be any from the android market or even one of the pre-installed ones) time? Does anyone know a source or perhaps measured those numbers?
View 9 Replies View RelatedI want to develop a game, so I need to know elapsed time at lots places in my game. For example, to measuring FPS. I see there is some example use "System.currentTimeMillis" to measure elapsed time. But I see the warning on document: http://developer.android.com/intl/zh-TW/reference/java/lang/System.ht... "This method shouldn't be used for measuring timeouts or other elapsed time measurements, as changing the system time can affect the results." So, if this method should not be used for measuring elapsed time, then what will be suitable?

View 1 Replies View RelatedI am trying to get a local time from a server UTC time. I get the UTC time form the server -- and i want to make it right for each individual Android phone whether it be in California or China. This is the code I am using now -- however it snot working.The time I get from the server is "2010-08-17 19:41:13.0" And the code I use to get the difference(in seconds) is the following: public static long getSecondsDifference(Timestamp timeStamp) { final Calendar calendar = Calendar. get Instance (Locale.getDefault()); int refrenceOffset = TimeZone. get Default (). getOffset(timeStamp.getTime()); final long referenceSeconds = (timeStamp. get Time() + refrenceOffset) / 1000; final long currentTimeSeconds = (calendar. getTimeIn Millis()) / 1000; final long differenceMinutes = (currentTimeSeconds - referenceSeconds) / 60; return differenceMinutes; The timestamp is from the java.sql.timestamp package.Right now the time where I am is 11:50AM -- and the method returns that the given server time is -53 minutes ago( so obviously doing something wrong

View 4 Replies View RelatedI just got the magic yesterday and so far I'm loving it. Just have a couple questions about texting. When I receive a text it usually tells me the time in eastern time though I'm pacific. However, my sent messages come up with the right time. This makes it so that threaded sms is kind of useless. Everything is all out of whack. Also, every once in a while it just won't even give me a time and there has been once or twice(after fiddling with it for a bit) that it gave me the right time but it just went back to the wrong time right after. Could this be a problem with the phone or is it rogers' fault? I'm assuming it's getting the time from the network and they have it wrong(meaning I can't fix it) but I just wanted to see if anyone else has had this problem.
Also, is there any way to make it vibrate when I receive a text? I feel dumb for asking this as it seems like it should be something really obvious but I can't seem to find it anywhere.
Is there a way to keep the phone from changing time as you cross time zones?
View 4 Replies View RelatedI recently received an LG optimus f3 with android 4.1.2.
After activating the phone, it displayed the correct date and time for my time zone, so I didn't mess around with settings to reset the time, as I would with any other device.
However, I've noticed that the time changes to exactly an hour ahead, before changing itself back several minutes later.
I went to settings > date and time, but 24 hour time and selecting a date format are the only options listed.
I prefer to leave mobile data off when I am at home and can use the wi-fi. Is it necessary to have mobile data turned on, so the phone can receive the time from a cell tower, or is there a way I can set an internal clock?
When i'm connected to my router at home via wifi, the connection randomly drops from time to time. My laptop and TV is fine which are both running via the internet. The setting is set to stay connected always, even when the screen goes black.
Does anyone have a resolution for this? Perhaps static IP? if this is the answer, what should the settings be?
I was having the waketime/sleeptime problem that many, many folks have reported and my battery life was obviously crap...and took forever to charge as has also been noted. I had already turned off all the auto-update stuff that I did when I first got the phone. Then I read the many posts abut Facebook app being the problem, but when I tried that it turned out that I was still running the old version 1.2, so apparently that wasnt causing it on my Evo.
Not really wanting to do a factory reset, I thought I'd check for other app updates in case one of the other apps had 2.2 bug fixes. Ran a sync thru the AppBrain app, and it found three updates that I hadnt been notified of:
Once those updates were completed, my EVO immediately starting going to sleep as it used to. I watched it for a few hours after the update and it continued to show realistic numbers for wake vs. sleep. My battery was almost depleted at this point, so I powered it off, and did the battery pull for good measure before powering back on and plugging in to charge during the night. This was all late Thursday night. All day Friday my battery performed VERY well...much better than even during 2.1. I had it on charge most of the day while listening to Pandora at my desk. I unplugged it to go home and now checking it this morning, it's now been off charge for 14h 39m, show wake time of 33:44 vs. sleep time of 15:28, and shows 80% battery remaining! This whole scenario makes me wonder if one of those three apps had a similar bug to Facebook. If you have those...you might want to take a closer look.
I have tried searching the database for this and googled it and I couldn't find anything.
I'm not very experienced in Android, however, I am trying to develop an application. Within the application I want to check if the current time falls between time ranges
pseudo code
[HIGH]if (currTime > 9am AND currTime < 7pm)
{
//do this
}
else if (curTime>7pm AND currTime <10pm)
[Code]...
How can I determine if the current time is between two other time objects?
For example: current: 15:23, startTime: 22:00, endTime: 06:00. So the current time is not between this two other times, but this "23:47" is.
*I don't care about the date, only the time
I tried to do it like this:
Code:
Time startTime = getStartTime();
Time endTime = getEndTime();
Calendar c = Calendar.getInstance();
Time now = new Time(c.getTimeInMillis());
[Code]...
but it dosen't work well. their aren't any errors but it just dosen't work.
To be more precise the problem is that 15:35.after(22:00) return true... and I don't know why. I think that the problem is something with the dates but I don't know what
I have a My Sql database that stores a time stamp for each record I insert. I pull that time stamp into my Android application as a string. My database is located on a server that has a Time Zone of CST. I want to convert that CST time stamp to the Android device's local time.
