Android :: Know Which Overlayitem Is Being Tapped?
Nov 17, 2009Currently 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?
Android :: When Do I Update OverlayItem List?
Jun 24, 2010From 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.

Jul 8, 2010I 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....

View 1 Replies View RelatedAndroid :: Add TextView/Layout To Map's Overlay / OverlayItem?
Apr 12, 2010When 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.

Android : After Removing OverlayItem Tap Events Are Still Trigger / Fix?
Oct 27, 2010I 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.

Mar 20, 2010I 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.

Dec 29, 2009I 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.
Android :: Contact Custom Fields
Jun 9, 2010Alright, I'm a little new to the Android SDK, so forgive me if my question doesn't make sense or is very trivial. I'd like to add a custom field for contacts, that contains the contacts username on a website I'm doing this app for. And, with this custom field, I'd like to have the ability to click it (like "Send message" or "Call mobile") so that I can go to a specif Activity in my application, with a TextView set with the username that I just clicked on.Sorry if that is a bit confusing, if you need anything else let me know!

Feb 3, 2010I would like to use EditTextPreference to show 2 input fields instead of 1. For instance, a username and password field should be shown. I don't want to use a dialog for each one. How can this be done? In the WiFi settings there is one that does this, when you want connect to a protected network, a dialog shows to set a password for the credential storage with 2 fields.
View 1 Replies View RelatedAndroid :: Combining Subclasses Which Have Different Fields For Efficiency?
Feb 7, 2010I'm working on a Java Android game. Games here generally need to use memory pools to avoid garbage collection.Making use of subclasses is a pain when using memory pools as you need to e.g. say how many Roamer and Chaser objects you want upfront and not just how many Enemy objects you might need.I would then have an update function that checked the "type" variable and updated accordingly. This is obviously a more C-like approach. It feels hacky though because e.g. a roamer enemy will have a "target" variable it never uses. I'm unlikely to have more than a 100 enemies in memory at a time though so it really isn't a big deal memory wise. I just want some compromise between nice code and speed.Does anyone have any comments on how best to structure this? Is merging classes like this going too far? Is this ever a good idea? Should I just use a regular class tree?

View 5 Replies View RelatedAndroid :: Private Fields Naming Guidelines
Jan 25, 2010Here http://source.android.com/submit-patches/code-style-guide#shortmethods it is stated that :
"Field Names
* Non-public, non-static field names start with m.
* Static field names start with s.
* Other fields start with a lower case letter.
* Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.
also states that : "The rules below are not guidelines or recommendations, but strict rules. You may not disregard the rules we list below except as approved on a need-to-use basis." I don't like the "m" convention before private or package fields in a class... I really find this uninspired. I mean, if we try to apply good designs, the low coupling of the classes implies having few public fields. actually, in my programs I usually have no public fields, even when I need some I use getters and seters. so, why should I be forced to have almost all my fields in the program with an "m" in front of them? wouldn't be easier to have the few public fields, if there are any, with some "g" in front or something? or just use setters and geters as beans suggest? this really makes my code harder to read. also, following these guidelines, local temp variables used in the methods have no restriction so they could easily be mistaken for public global fields (also without restriction). this also I find to be wrong, as it is a probable source of mistakes. I understand to have a way of differentiating from fields, but private/protected member fields are the most used in an application, they shouldn't be less "readable". what do you think? should I follow the guidelines?

View 4 Replies View RelatedAndroid :: How To Implement Custom View With Variable Fields?
Jul 7, 2010I have a ListView that displays a set of notes, each with varying ammounts of data (i.e. some have a due date, others don't).Currently, each view in the list is a RelativeLayout containing a TextView for each field, plus two Button and a CheckBox. I then simply hide the unused fields by setting visible false on each one.This has worked well, but I'm about to add a lot more data fields to the notes and inflating that many unneeded views for each row will surely kill my app. I need a more dynamic solution.I've decided the best way to go is to create a custom view. How can I implement/design my view so that it can display a variable number of text fields without creating/ destroying textviews each time (which would be quite expensive and worse than my current situation), or maintaining a large pool of hidden textviews?

It does not compile on 2.1. The static fields DIRECTORY_PICTURES, DIRECTORY_MUSIC etc. Don't seem to be found. Using the filter api checkbox, I see that it was removed in Android 2.2 (or api version 8). So the manifest file needs to contain minSdk defined as 7.
