I am new to Android development and have been working on a simple demo app that needs to update a TextView a few times from an array after a button is clicked. I have read and adapted the code found here to achieve this: http://developer.android.com /resources /articles /timed-ui-updates.html
View 2 Replies View RelatedI have looked at every discussion and thread I can find on getting this to work but it is not. I have a simple timer that updates a text view (mTimeTextField in the example below). The mUpdateTimeTask run method is being executed correctly (every second) but the UI/text field is not being updated.
Here is the code:....................
I want a widget showing a countdown for a user initiated tracking of a bus departure. I want to update the widget every minute or so, from when the user initiates the tracking to when the bus has departed (i.e. the time runs out). This widget needs to be updated more frequently than what updatePeriodMillis allows, which is every 30 seconds. I reckon about once a minute. Being new to Android programming, I can think of a few ways to do this, but I would probably end up doing it in a way that consumes way too much battery etc, so I'm looking for some insights from more experienced Android developers. How do I start the timer? How can I access the widget instance from my applications run-time? And so on.
View 1 Replies View RelatedI would like to further annotate the custom markers I have placed on a MapView (using ItemizedOverlay) by displaying a simple text label that appears for a particular item when the onTap event is fired.
This is a trivial exercise in the Google Maps JavaScript API and in MapKit on iPhone, but it is not obvious to me what the best or easiest way to do this is on Android.
I try to add a table layout from Java code. When there are two fields in a tablerow it displays the first field only. How to display the entire row with all fields?
code... How to do this?
I want to display GridView (with text and image) and group of text box below grid view.
Problem is my gridview do not have fixed entries. It is varying between 1 & 10. I want to resize it as per count of items in grid view. How can i do that? Where can i get height of gridview in JAVA code?
Also, i want to display my group of text boxes ALWAYS at bottom of activity. How can i do that?
simple question. In a class, if I wanted to set the text to the text value of a string I have, what is the code for that?
I have: TextView textView = (TextView) findViewById(R.string.noFaceFive); textView.setText(textView);
but setText says : The method setText(CharSequence) in the type TextView is not applicable for the arguments (TextView)
is there a set Text to display the text of a string? Serious mind fart on my part.
I would like to know if it's possible to display an activity inside a layout of my activity. For example I would like to display the Phone application inside a layout of my activity.
View 3 Replies View RelatedI have a webview I'd like to display as a dialog. I'd like the webview to fill the entire screen, except for a button below it that I'd like to stay at the bottom of the dialog regardless of how much content is in the webview. Currently my webview fills up the dialog just enough to push the button off the screen. I'm sure this is something pretty easy but for the life of me, I haven't been able to find the magical combination of layouts, views and attribute values to get it to play nice. Just to be clear, I've gotten it so the button floats over the webview but I'd like the webview to stop just above the button and scroll, if that makes sense.

View 1 Replies View RelatedI'm new in Android. I searched a lot to get a table with borders, but I am not getting result.
I want a table with two colums, borders, white backgroud in table. first colums should be right aligned and second column should be left aligned.
With TableLayout, rest of things can be done, but not I can get table with border in display.
In Android, I wrote a number of strings in my string.xml I would like to display on a TextView based on a random number...code...
But I know I am not doing it right because I get the error:
The method array50(int) is undefined for the type MAIN. Any ideas?
So this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is:
And the code to call and show the alert dialog is..
When I run it I get an error saying:
Uncaught handler: thread main exiting due to uncaught exception
android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application
I've looked through the android development site and can't figure it out. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?
I have an app where pressing button on the screen launches an intent with a new screen and buttons. Everything is working very well, but I'm got one small visual problem. When I press the button on screen on my phone, the new page slides in from the right, pushing the old page off screen left. This happens very quickly, but the overall effect is a bit jarring. Is there a way to stop pages from display this way? If possible, I'd like the page to just appear over the old page, without any scrolling.
Is this possible in Android?
In my android application, I have an Edit Text. When I click in this field, the soft keyboard appears, expanding from the bottom of the screen. It seems to actually modify my layout, pushing contents up wards. When I dismiss the keypad, it retracts, and I see my layout re-expand to take up the space it previously occupied. Is there a way to get the keyboard to simply appear "on top" of my layout, so that I don't get this somewhat unpleasant relayout animation? The Edit Text is pinned to the very top of the screen, so I don't have to worry about the keypad hiding it.
View 2 Replies View RelatedI am using a ListView to display my custom item layout, which may contain some TextViews and an ImageView.
This is the item layout I made (post_item.xml):
CODE:........................
I don't put the ImageView initially in the xml layout, but I will insert it when I need to the FrameLayout programmatically (I also put another views in it when needed). So, there will be some items which has ImageView in it and which don't.
I get the image to fill the ImageView from the Internet (through URL), decode it as Bitmap, and keep it as a Bitmap variable in a class represents the custom item layout (class PostItem).
When the activity shows for the first time it looks fine, but as I scrolled through the items then a problem showed up, the items which shouldn't show any image show the image from the other item which should, although they don't have any ImageView (because I didn't insert it).
I am using SDK 1.6 and the emulator. Haven't tried it in real device because I don't have it.
Here is my code for the Adapter:
CODE:..............
And this is the code to prepare the items:
CODE:.........................
Is this the bug in the emulator or there is some mistake in my code (probably memory problem for the Bitmap)?
If I want to dynamically display graphics or text in layout, can I still use xml or I have to hard code?
View 2 Replies View RelatedAnyone having trouble with widgets stop updating? Like my clock/calendar/weather/news/pretty much any widget i have stops updating after an hour. So i look at my clock widget two hours later and it is an hour behind. Happens to ALL my widgets.Even the quick turn on/off wifi,bt,gps and such. They just stop updating/showing animation.I have ADW launcher installed. I am wondering if it is that. I do not really want to remove it as i hate the stock 3 button interface at the bottom (why do i need a contacts and phone, just use the phone to look thru contacts, wasted space IMO) and am quite keen on keeping the 5 button.Any ideas? If i power off the phone and turn it back on it's fine again for about an hour. SOmetimes randomly thru the day it will start updating and working fine again then randomly stop again.
View 12 Replies View RelatedI'm setting background color based on a given state of an object in each row in a list. That part is working just fine but when I set the background color on the outermost layout the row no longer highlights when selected. Probably a specific attribute I'm not setting/changing?

View 4 Replies View RelatedAnyway, if you're like me and go crazy that the icon text for handcent doesn't fit in the allotted space, you can delete that icon, long press on the screen, and add the handcent widget. This has a label that fits on the screen and acts just like the original icon. I know you can do this with bettercut, but some people don't want to use it.

View 3 Replies View RelatedI have a zillion labels. Only way to manage the old digital life Any who, it's a PITA going into GMail and scrolling through the astronomical list of labels to see what's in there. Needless to say, some labels are, to me, more important than others. With that in mind, what I'd like to know is how I can create a shortcut on the desktop that will go directly to a specific label in GMail. It's gotta be possible.

What exactly does the gmail option "Labels: select wich labels are snycronised" do? Does it mean if I had a label set up and told it to go directly to that label and skip the inbox that i would still get an alert on my phone? The reason i am asking is because before i got this phone, i had a label in my gmail called "craigslist". Everything dealing with craigslist went into this and skipped the inbox. Thats worked well but i still need to be alerted when i get a new offer from craigslist. Will that snyc label option do what i want it to do?

View 1 Replies View RelatedI know that a lot of you have been having issues with this app. I thought that I'd try to make some suggestions that could or could not solve things.
- Make sure that you press the "Turn on alarm" check box at the very top of an alarm. I've missed it once before (my first time) and thought it was on because I pressed "Done" and even though it said that it was set for "6 hours and 53 minutes from now", it wasn't activated.
- Turn on "Vibrate" and have it rest on a wooden surface, like a night stand for example.
- Have "Repeat" set to the day that you want it on, even if its just for that day. This has helped some people.
- Have the "Backup alarm" on just in case.
- Have the volume turned all the way up. This definitely wakes me up every time because it can get really loud, especially when you're sleepy.
- Instead of playing one of the stock alarm ringtones, play an MP3 file. Play a song that can get loud, but I recommend to turn on "Volume" (which increases the volume gradually) so it doesn't startle you.
- Make sure that the speaker on the back isn't at risk of any muffling by fabric.
- Turn your phone over on its front to completely expose the speaker.
Go ahead and try a test alarm with all of these in mind (like set it to go off in 2 minutes) and see how it works out. I've made my mistakes by accidentally leaving it on a T-shirt (which definitely muffled the sound), forgetting to turn up the volume loud enough, and by forgetting to actually press "Turn on alarm" (as previously stated). If any of those suggestions do not work out for you, then you're on your own with a 3rd party app.
Is there a way to get the application label in different languages according to locale? For example, I can get the application label "Settings" of package com.android.settings in English, "Ajustes" in Spanish.
