Android : After Removing OverlayItem Tap Events Are Still Trigger / Fix?
Oct 27, 2010
I have a simple overlay for a Google Map: http://pastebin.com/Rg8miMSh and I add/remove items on it depending on the zoom level. After removing/adding I call populate on the overlay and invalidate on the map view. Everything works just fine, except 1 glitch: after an item was removed, if I tap its location onTap is still triggered and because the OverlayItem is not there anymore i get java.lang.ArrayIndexOutOfBoundsException in com.google.android.maps.ItemizedOverlay.maskHelper(ItemizedOverlay.java: 562) (full stack trace - http://pastebin.com/KThn4ZLE )
Anyone knows why this is happening or how to fix it? Initially i called clear and added all items all over again which didn't seems to cause this problem. However having many items this was becoming a performance issue. Adding/removing only the difference works much faster and I would like to keep this method.

I have attached the zip file for the complete source code. And you can test in on your computer.Why is it only the onCreate and onDestroy will executed ? But the rest of the functions are NOT executed. I need those functions to be executed specially the function that are under this class VoiceResultsListener . And get the result on this procedure : public void onResults(Bundle results).
public class SimpleVoiceService extends RecognitionService {
private SpeechRecognizer m_EngineSR;
@Override
public void onCreate() {
[code]...

Currently I used a map view and placed some overlay items in them
I overiden the onTap function in ItemizedOverlay so that when user tap on the markers icons on the map, some action will perform.
However, I don't know how to know which marker is being tapped so that the related data of the item will be displayed in the screen. How can I do that?

From everything that I've seen and have been reading, I'm apparently supposed to add all my OverlayItems in the constructor, then call Populate().The problem I have conceptually, is that if I'm pulling these items from a database (fed by a web site), then when exactly do I update the items?Also, it seems to me that it's a waste of resources to feed it all the items in advance instead of the ones pertaining to the current location... This seems to be the perfect case to use a ContentProvider, but I don't see anything indicating that one can be used with either ItemizedOverlay or anything else related to the Google Maps API.

I want to be able to get some reference to the curent object being drawn. code...
Above is my draw method and I want to extend the draw method to write the title underneath each item for example. This would require the .getTitle() method from the OverlayItem. Possibly some tracking of objects outside of this method but not sure where to put it....

When a marker is clicked on google map, a small square area is displayed with hyperlinks. I guess OverlayItem does not render hyperlinks for its snippet. How to achieve this? Ideally I want to assign a layout with all sorts widgets. Presume I can display a small floating activity window when the marker is clicked, but is this the standard way doing this? The drawback of floating activity window is that if want to click another marker, user has to dismiss the current window first.

I am able to display multiple overlayItems on Googlemap, now I want to change icon of any specific overlayItem (to show it is currently selected event). I want to do it through navigation buttons (next, previous) as on Google maps.
I am using StateListDrawable to display icons for OverlayItems. code...
Now my question is how do I change the state of any overlayItem/Icon on map when user click on one of navigation keys?

I currently have implemented an overlayitem that shows an icon for geopoint on a map application in Android. When the icon is clicked, it brings up an AlertDialog from the onTap method below.Does anyone know how to display a map message bubble directly above the icon overlayitem with 2 callout buttons one to the left of the title and one to the right of the bubble? Does anyone know how to make the overlayitem draggable so I can press and hold it and drag it across the map. I am trying to duplicate the draggable icon behavior that's available on the iPhone.

I 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.

Can someone clue me in on the name of the intent that triggers the haptic feedback when the user selects icons on the desktop, or when in Labyrinth the ball hits the wall. I thought it was vibrate ... but after playing with Labyrinth I am sure there is something else. In Labyrinth it feels as if the thump occurs relative to where the ball hits (but I am not sure if this is really the case or I am imagining it).
I asked about this before and thought I had figured it out myself (thought it might be a short burst of vibrate) but apparently not.

I want to expose a portion of my app with an intent that will only display a simple dialog box for system setting. The only way I currently know how to do this is to have an activity that accepts an intent. In the activity I don't use setContentView. I only create and show the dialog. The activity is finished after you press OK from the dialog.
This is kind of okay, but the activity shows as a black backdrop under the dialog, until you press OK which brings you back to the last application. I'd like to just be able to show the dialog on top of the calling Activity. Any idea on how this can be done? CAN it be done?

Can anyone give a hint if you know why there are some ACTIONS that do not trigger their associated receivers when they are registered in the manifest while they are received when they are register through registerReceiver() ? For instance, when I declare: <receiver android:name=".MyReceiver"> <intent-filter> <action android:name= "android.intent .action .NEW_ OUTGOING_CALL" /></intent-filter> </receiver> if the application is NOT running My Receiver is never invoked. But now, if I register the intent from inside a service, MyReceiver is invoked properly

I have a layout that looks like this (some attributes removed for brevity)
<RelativeLayout>
<ImageButton
android:id="@+id/button"
android:nextFocusRight="@+id/gridview"/>
<GridView
android:id="@+id/gridview" />
</RelativeLayout>
When I navigate using the DPAD from the button to the gridview, the OnItemSelectedListener is not fired. However a new layout pass is perform. Why is this ? Is this an android bug & my bug?

If (in Android) I have an EditText box, how can I trigger an event when the user has finished entering data and hits return/Next?
I have tried using the code below but it seems to have no effect. I also get an 'The method onEditorAction(EditText, int, KeyEvent) from the type new extView.OnEditorActionListener(){} is never used locally' error.
myEditText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
public boolean onEditorAction(EditText v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_NEXT)}

I want to show the softkeyboard, but it does not work. Here is my code...
When i touch the screen, the softkeyboard does not appear, but the alertDialog "edit text" appears, which appears on normal edittexts when you long touch them.
This additional code in the onCreate has no affection:
InputMethodManager input = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
input.showSoftInput(myTextView, 0);

I am rendering an EditText as one element of a list-style AlertDialog (which is backed by the default ListView implementation). I sort of expected that this circumstance would not change the behavior of EditText, but it does: a click on the EditText does not spawn the soft keyboard anymore.
After an hour of messing around with focus settings and click handlers I got fed up and debugged into InputMethodManager.showSoftInput(), and found this:
CODE:....................
The problem here is that mServedView is the ListView that's backing the dialog, while view is the EditText, and ListView.checkInputConnectionProxy() does simply return false in the default implementation of ListView (to be overridden by subclasses).
Worse, I couldn't find a way to set a custom ListView which allows proxying IME reuqests; AlertDialog.Builder.setView() accepts a custom ListView, but this is not the ListView that InputMethodManager sees.

I have a requirement wherein I need a list of all the contacts that are edited/changed.
As per the Android documentation,
_SYNC_DIRTY
will be set every time a contact is edited. But, there seems to be a bug in this, which makes this always set to 1 (no matter what), even is we explicitly set it to 0.
So, I was wondering if I can create a SQLite TRIGGER on the contacts database. Such that, everytime a contact is edited, the edited contact id is populated into a different table which I can read later from my application.
I tried this...
CREATE TRIGGER IF NOT EXISTS updated_contacts UPDATE ON 'contacts.db'.phones
BEGIN
INSERT INTO updated_table SET updated_id=old.person;
END;
But a few problems here...
1) 'phones' is a table in the contacts database. but, I am not sure about the name of the contacts database (here I have assumed it to be 'contacts.db').
2) updated_table is a table on a different database 'mydatabase.db' that I have created from my application. and, I am not sure if I can set TRIGGERS across different databases.
All this in Android 1.6 Also, I am not sure about the permission to access native contacts database on Android.
Is there any other way of achieving this.

I am trying to build an app on my wife's phone that pranks her on April 01, April Fool's day of course. The app is going to change her background to look like the screen was cracked, the background is very convincing when I try it on my Droid (I was pranked similarly).
Anyway, digging into how this would work, I think its quite the process, however, I may be looking too far into this. I started diving into setting an alarm, however, I am confused about a couple things:
Would it be necessary for my wife's phone to load this prank application in the background each time she reboots her phone? I am assuming yes, as I believe this prank application would most likely invoke a broadcast receiver to "listen" for April 01, 2011?
If the application doesn't need to load each time in the background, what facilitates Android alerting my application and firing it when April 01, 2011 comes around?
I hope that makes any sense, basically, I want to ensure this application runs on April 01, 2011 even if my wife's phone crashes or reboots.
What would be the most straightforward method of making this work? I apologize if I don't understand broadcast receivers properly, this is quite the new concept which I am not use to. The Service and Broadcast Receiver functionality is native to Android and not any other language, no?

I have a website designed for the android browser using jquery/jqtouch. As a part of it, i have a map page that loads. In the process of displaying my data, I found that some of my customer's addresses, when clicked kick of the google app map, with the data sent to it. It also seems to load and run a ton faster (as well as having all the benefits of navigation, etc).
So I've searched and searched, but am unable to "emulate" that built in function of kicking off the address. I've tried links with geo: and maps:, etc, but to none will open the installed app. Yet, just having a <li></li> item with an address, the browser will detect a "proper" address and open the app.
I don't care if i have to kick it off with javascript, or a href, it just has to be embedded in the html.

I've been searching a way to implement an intent so when a user clicks on a notification, an specific method from an activity is executed (or an specific behavior happens). Right now I'm thinking about using broadcast but I don't know if this is the best way to implement this functionality. How would you implement it?
