Android :: Unable To Get Correct Selected Items

Apr 17, 2010

I am to display the list and store the selected items in an array. But I am not able to get the correct items that were selected. Here whenever the user clicks an item, the array is getting updated, irrespective if the user is clicking the item to select it or deselect it. Could some one please help me solve this. I could actually perform an iteration to remove the odd numbered items in the array but I feel that would become an overload on the phone. Is there something for efficient. Please advise.

public class MainActivity extends ListActivity { TextView selection; String[] items={"sodium", "O2", "C02", "HCL", "NaCl", "H2So4", "O3", "Ag"}; String names[] = new String[10]; static int i=0; int posarray[] = new int[10]; @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, items)); .........

Android :: Set Selected State Of An Item In A Gallery (correct Way)?

Jul 24, 2010

I have a gallery that displays TextViews where the background of each view is the following code...

This selector work just fine for the state_pressed and default (idle) states, but the selected item state is never displayed. I REALLY do not want to force the background of the selected item by changing the background of the view when the onItemSelected event is called. What is the correct state or correct way to get the TextView background to be set properly. Is the selected (center) view in the gallery not really selected? Is there some other state I should put in the selector drawable xml?

Android :: Unable To Get Selected Value Of Spinner / Way To Do In Phone

Apr 16, 2010

I'm trying to get the selected items string out of a spinner. So far I've got this:
bundle.putString(ListDbAdapter.DB_PRI, v.getText().toString());

This doesn't work and gives a casting exception (I thought you could cast a view to a widget that inherits it... obviously not!). So how do you get the selected value of a spinner

Android :: Unable To Get Correct Screen Size Using Services For Droid / Way To Fix It

Sep 2, 2010

So i am trying to get the screen size of the Moto Droid on my application. on my Create, i am using the Service windowManager to get the default display. code...

When i set it i get width of 320 and height 570. that looks wrong, it should be 320x480.
i want to place a 300x50 image on the bottom of the screen on any device (actually) so normally i would get the height of the screen and minus the image height so it places it on a view. but since i am getting 570 for some reason, i have to scroll down to see the image. why is it getting the wrong screen size and is there another more accurate way of getting the size. code...

Samsung Captivate :: Way To Have Single Folder Show Received Items / Sent Items Combined?

Jul 21, 2010

Had no problem getting my phone to play nice with our exchange server at work and emails are coming/going fine.

However, there are some configuration items I have a big issue with as it relates to the 'look' of the email (coming from a BlackBerry).

1. Is there any way to have a single folder show my received items and sent items combined? My BB had this and it was very useful.

2. How can I edit the way my folders are displayed at the top horizontal bar? The sidescrolling folder display is awkward, it puts my inbox first (good) but then all subsequent folders are listed alphabetically; it pays no attention to their order on my desktop and also shows sub-folders of other files. Any way to change this?

3. Is there a way to change the way emails show as unread? The difference b/n read and unread is only a shade of grey, and difficult to see outside.

Android :: Get Phone Correct Timezone

Nov 14, 2010

I am trying to get phone's correct timezone. I tried String newTzID = Calendar.getInstance().getTimeZone().getID(); This is returning "America/Atikokan". But my phone's timezone is EST. Both of these have an offset of GMT -5 hours. But I actually need to differentiate between EST and "America/Atikokan", since "America/ Atikokan" doesn't have day light savings time. Is there a way to get the correct id?

Android :: Correct Way To Add Objects To An ArrayList

I am trying to add an object to an arraylist but when I view the results of the array list, it keeps adding the same object over and over to the arraylist. I was wondering what the correct way to implement this would be.


I have double checked my JSONArray data and made sure they are not duplicates. It seems to keep adding the first object over and over.

Android :: Correct Use Of TaskAffinity & LaunchModes ?

Sep 28, 2009

My android app contains a suite of mini apps. In short, the main screen contains several icons, one each for the mini apps. When an icon is clicked, the mini app is launched.

In total I have 4 mini apps. So you could imagine that my main screen is like the Home Screen Launcher. Although these mini apps could run standalone by their own, I want the user to be authenticated. Thus there is a LoginActivity right before the MainActivity.


I'm still not pretty sure of the benefit of Tasks (arranged set of Activities), so I would like comments from Android experts on my design decisions:-

(1) I plan to set the attribute finishOnTaskLaunch to true for LoginActivity. As I understand it, once the login is authenticated, I will navigate the user to MainActivity, and I want LoginActivity to disappear. Is this better than calling #finish on the Activity ? Will MainActivity automatically become the root of the Task without any extra configuration/code ?

(2) One of the mini app is an IM client. The PresenceListActivity will hosts many instances of ChatActivity (one-to-one chat session with an active contact in the buddylist). I plan to use the default launchmode for ChatActivity since each Chat should be handled by a new instance. Sounds correct ?

(3) A sticky navigation bar will exists in the top corner of AppOneActivity, AppTwoActivity etc.. I plan to set the clearTaskOnLaunch attribute to true for all of them. As I understand it, I should clear the stack whenever I plan to launch into any of the mini apps. Also their launchModes will be singleTask. Am I on the right path ?

(4) Finally I don't really understand how to read the output of adb shell dumpsys activity. For example


Sometimes underneath the Tasks, you will see History and in others Running, what do these mean ? Even stranger, sometimes I have two History under a task.

Android : Is Way Of Doing Threads In Phone Correct

May 17, 2010

I'm writing a live wallpaper, and I'm forking off two separate threads in my main wallpaper service. One updates, and the other draws. I was under the impression that once you call thread.start(), it took care of everything for you, but after some trial and error, it seems that if I want my update and draw threads to keep running, I have to manually keep calling their run() methods? In other words, instead of calling start() on both threads and forgetting, I have to manually set up a delayed handler event that calls on both the update and draw threads every 16 milliseconds. Is this the correct way of having a long running thread?

Also, to kill threads, I'm just setting them to be daemons, then nulling them out. Is this method ok? Most examples I see use some sort of join() / interrupt() in a while loop. I don't understand that one...

Android :: Where Selected Wallpaper Saved?

Feb 10, 2009

When a wallpaper is set (either from the Wallpaper Gallery or from Pictures) where is the wallpaper that is selected saved? Is there a directory where this is saved? Is there a Database where this information is saved? who handles this? Is it the wallpaper service? What if I wanted to have multiple wallpapers and have the service rotate through each of them based on some setting - every 1 hour for example - what do I need to change in order to do that?
