  • How do I get this linearlayout working on android?

    - by Arkadiy
    I'm trying to create a scrollview that contains a linearlayout with some options inside of it. I'd like for the options to show up at the top and grow downwards, and to have "save," "delete," and "cancel" buttons which show up at the very bottom of the screen (if there is space left in between the bottom of all the options and the top of the buttons). Here's a screenshot of my attempt: http: //img375.imageshack.us/img375/3628/10370572.png (StackOverflow was only letting me post a single link so you'll have to get rid of the space in between http: and the rest) As you can see, the buttons show up directly below the options rather than at the bottom of the screen. In fact the top level (green) linearlayout doesn't even extend all the way down, despite having a height of fill_parent and a weight of 1 (and the blue is the scrollview, so there is room to expand). I've tried every possible combination of heights, weights, gravities, and anything else to get this working and still can't do it. Everytime I pasted my xml layout into here, the top and bottom portions got cut off, so instead I pasted it here: pastey link Can anyone see what I'm doing wrong?

  • Is it possible to open a context menu from a map overlay item in android?

    - by John Nicholson
    This below code works fine opening an alert dialog. I was wondering if it's possible to open a context menu from within a map overlay class? @Override protected boolean onTap(int index) { OverlayItem item = mOverlays.get(index); AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); dialog.setTitle(item.getTitle()); dialog.setMessage(item.getSnippet()); dialog.show(); return true; }

  • Is there a design pattern to cut down on code duplication when subclassing Activities in Android?

    - by Daniel Lew
    I've got a common task that I do with some Activities - downloading data then displaying it. I've got the downloading part down pat; it is, of course, a little tricky due to the possibility of the user changing the orientation or cancelling the Activity before the download is complete, but the code is there. There is enough code handling these cases such that I don't want to have to copy/paste it to each Activity I have, so I thought to create an abstract subclass Activity itself such that it handles a single background download which then launches a method which fills the page with data. This all works. The issue is that, due to single inheritance, I am forced to recreate the exact same class for any other type of Activity - for example, I use Activity, ListActivity and MapActivity. To use the same technique for all three requires three duplicate classes, except each extends a different Activity. Is there a design pattern that can cut down on the code duplication? As it stands, I have saved much duplication already, but it pains me to see the exact same code in three classes just so that they each subclass a different type of Activity.

  • How to use intent between tabs in java/Android?

    - by Praveen Chandrasekaran
    I would need to know how to handle the intent between tabs. For example, I have a tab activity with two tabs. First on content is a text view. another one is a map view. When i click that text view it redirects to the tab2. it can be easily achieved by setCurrentTab(1) or setCurrentTabByTag("tab2") methods. But i want to pass lat and long values to that Map Activity to drop pin. What is the better way to use intents or getter/setter in java? What do you prefer? if your answer is "Intents". How?

  • How do I find out what android system icons mean?

    - by The Trav
    Ok, so I've got an andoid phone with a bunch of icons up the top, looks like app notifications go on the left, system icons go on the right. Most of the system icons seem reasonably intuitive, service, 3g, wireless etc. I've recently gotten a new one that looks like a phone being tilted / shaken and have absolutely no idea what it means. Is there a reference site where I can look this thing up?

  • Android animation doesn't work, probably some kind of screen redraw problem.

    - by BenIOs
    I have created a custom component in my program by extending a ViewGroup. This component listens to touch events and are supposed to start animations when the user has move their finger past some certain points. I'm able to start animations while the user is touching the screen. But I'm not able to start animations if the user doesn't move their finger. It's probably that the phone thinks it doesn't have to update the screen if the user isn't moving their finger. I added some logs and according to them the animation starts and ends but it doesn't draw on the screen. I have the same problems when starting an animation with a timer. I use AlphaAnimations and TranslateAnimations on ImageViews. I have tried to use invalidate() both on the component and the ImageView but it doesn't help. Anyone who has an idea how to solve this?

  • How to display a non-model, temporary pop-up message in Android?

    - by chefgon
    For an example of what I'm looking for, hit the Home button while you're composing a message in the Gmail app. A little message will pop up at the bottom of the screen for a moment that says "Message saved as Draft." I can't figure out how to display one of those messages myself, and I'm not sure what to call it so I can't do a search for it.

  • Android - How to prevent the phone screen from turning on when volume or camera key is pressed?

    - by 2Real
    I have an activity that shows up when the phone screen goes to sleep/turns off ie turns black. For some reason, the phone turns on when the volume buttons or the camera buttons are pressed. By turns on, I mean the screen wakes up or comes back from the black screen state. I've tried using dispatchKeyEvent(KeyEvent event) and the buttons are disabled on the activity, but they still wake up the phone.

  • How to create a status bar icon on the right side? (Android)

    - by yuku
    Notification and NotificationManager are used to create icons to be placed on the top-left position of the screen. A Notification also need to have an entry on the status bar pull-down. However, icons on the right side such as the battery, signal strength, wireless indicators do not need any entry on the status bar. How do I make such icons without any entry in the status bar pull-down?

  • Error becuase Virtual directory not being configured as an application in IIS

    - by Cipher
    Hi, I was trying to install a CMS in a folder in my website. After the installation on trying to run, it shows this error: Error 14 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. E:\Users\Sarin\Documents\Visual Studio 2010\WebSites\WebAssist\blog\web.config 61 I added the webiste as a Virtual Directory and also converted that to application. On trying to browse this application, the following error occurs as shown in the screenshot: http://i.imgur.com/jcRJe.jpg How to make this work?

  • Android how do I wait until a service is actually connected?

    - by Ryan
    I have an Activity calling a Service defined in IDownloaderService.aidl: public class Downloader extends Activity { IDownloaderService downloader = null; // ... In Downloader.onCreate(Bundle) I tried to bindService Intent serviceIntent = new Intent(this, DownloaderService.class); if (bindService(serviceIntent, sc, BIND_AUTO_CREATE)) { // ... and within the ServiceConnection object sc I did this public void onServiceConnected(ComponentName name, IBinder service) { Log.w("XXX", "onServiceConnected"); downloader = IDownloaderService.Stub.asInterface(service); // ... By adding all kinds of Log.xx I found that the code after if(bindService(...)) actually goes BEFORE ServiceConnection.onServiceConnected is being called - that is, when downloader is still null - which gets me into trouble. All the samples in ApiDemos avoid this timing problem by only calling services when triggered by user actions. But what should I do to right use this service after bindService succeeds? How can I wait for ServiceConnection.onServiceConnected being called reliably?
