I have a method in my ItemizedOverlay class which takes an object as a parameter and depending on it's certain values returns an appropriate icon. What's the best way to access the drawable resource from within ItemizedOverlay as you can't access it directly like in an activity? The only idea I have for now is to pass the resources as a second argument...

So I'm defining a class that sets a Drawable attribute in an object. The problem is that I can't access the getResource().getDrawable(int resourceId) method unless I have some Context.
So what I did was to send to that class an activity instance (let's call it "act") and then I did:
act.getResources().getDrawable(R.drawable.whellchair)
but, when executing that line it throws a NullPointerException.
When idea how to accomplish this?
In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?
I am trying to move a set of images currently in the resources/drawable-hdpi folder to the Assets folder.
These images are copied to the private application directory when the app is installed.
When I do this the resulting image is smaller than when I had the image in the resources folder. i.e. the baked beans image is smaller than the others. If I load the baked beans images from the drawables folder it is the same size as the other product images.
I have tried to scale the image but it has no effect.
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imView = (ImageView)rowView.findViewById(R.id.product_thumb nail);
ImageView imProduct = (ImageView)rowView.findViewById(R.id.product_icon) ;
tvName.setText((CharSequence) values.get(position).getName());
[Code]...
I'm thinking at putting a .txt file in res/drawable or in res/layout to have it in the apk when the application is packed, and then after install to open and read from it to perform some tasks . Can this be done ? If yes please let me know how can I access the file ,as I don't know it's path .

In a couple of other applications I have extended this subclass to provider a common menu for each activity. Is it still possible to access the resources from this Subclass? By default it uses the resources from the current activity (Strings, xml layout etc.).

View 3 Replies View RelatedCan a core class such as "AbsListView" access resources, such as xml files, and .png's, in a 3rd party app installed in the normal way (at the app level)?
I realize this is a change in framework code, and that is fine for my purposes. So, for example, if I know that I am going to install an app called "MyApp", could I go into frameworks/base/core/java/android/ widget/AbsListView.java and tell it to use an xml file and .png's that live in that app? Here is the line I would want to modify: setSelector(getResources().getDrawable( com.android.internal.R.drawable.list_selector_background));
I'm trying to write a layout similar to the timepicker widget layout.
So i decided to use the android framework layouts but i can't use them It seems that if i write android.R.drawable.timepicker_input or other timepicker related drawables i get them this Eclipse error: android.R.drawable.timepicker_up_btn cannot be resolved
So i tried to import all the pngs and xml from the android source but eclipse says there is an error in the manifest regarding the icon.

View 2 Replies View RelatedI have to make a dedicated image viewer app for Android 2.x.
There are too many jpeg image files: about 2000~ jpegs, over 100MB.
I want access the image files with their file names,
but I couldn't find such an example.
By the way, is it okay to put many image files in /res/drawable folder?
I heard that the android application cannot be installed on sdcard and
the program repository is very small so 100MB app cannot be installed generally.
I found some examples which download the large data files on sdcard online,
but I cannot run a web server to host the data files,
and I must upload the fully packaged program on Android Market. (Should I build one apk file?)
What are the best practices for managing too many resource images (or something) in Android?
We have a website that makes use of OAM for single sign on (form-based authentication). When we submit credentials to WebGate / Access Server the authorization succeeds, however after the authentication is performed, the form action (as configured in the Authentication Scheme - with passthrough:no) returns a server error instead of redirecting to the originally requested URL.
If we use Mini Opera, we are able to get authenticated and forwarded properly.
This problem happens on numerous Android phones (versions ranging from 1.5-2.2), as well as the Emulator provided with the SDK.
This is proving to be a real problem as the default browser on Android phones is not able to get access to our sites(and this is the only browser that is having this problem).

Here is the draw method of the ItemizedOverlay

I now print out the stacktrace and no difference!
I want to draw 20 pins on a MapActivity. Each pin has a small pin image, but I have to dynamically overlay a small bit of text over each pin at runtime.
Looks like I have two options:
#1) Itemized Overlay This is the suggested method. I put all my pins in one ItemizedOverlay object, and that counts as a single Overlay object for my MapView.
#2) One Overlay per pin Create a separate Overlay instance for each pin I need to render.
The problem I see with using method #1 is that you need to set a drawable for the item. This would mean that I need to create 20+20 (one for focused/non-focused state each) bitmaps and keep them in memory for the duration of my app. On the other hand, Overlay lets you override the draw method so I can do the simple compositing at runtime.
The other issue with Itemized Overlay - although it handles focus for you - does it move the focused item to the front of the z-order when selected?
I'm having some troubles with displaying ItemizedOverlay(s) on a map.
Here I extracted a simplified example of what I need to do.
Here's my Map class:
CDE:........
I followed the guide provided by google to extends the ItemizedOverlay class
CODE:...................
As it is clear from the code I need to update at fixed times a map UI with possibly new positions to do so I'm using a timer, but I think I might fall in some kind of thread issues I don't know how to handle, since when running a test I can see in the Log what happens but no marker is drawn on the map.
I have an itemizedOverlay extended and I want to increase the hit detection on the OverLayItem's if this is possible?
View 1 Replies View RelatedI'm using Google maps. I put the markers on map and my inherited ItemizedOverlay overrides onTap() method.
Markers are 32x32 images.
However, I can tap quite a bit away from the marker and still receive the event. This becomes a problem when markers are close to each other.
I have a MapView where I would like to be able to tap the map to create a new item at that location if there is no item there, or display the info about the item if there is.
I tried overriding both the onTap(int) and onTap(GeoPoint, MapView) methods but apparently if the second method is overridden the first never gets called (commenting one or the other lets each one work as I expected).
I thought about just checking if an item was at the location, but there doesn't seem to be any handy methods available to do that (other than iterating through the list of items and checking each manually).
I am developing an application for the Parisian Metro. One of the functions is a map where you can click the metro stations and see what are the metro lines, and when are the next 4 trains on this station.
I have hence created a MapActivity and an ItemizedOverlay classes.
On my device it is working perfectly, but I am getting some logs from the users with a crash, and I really don't understand what's wrong.
My map activity adds ONE ItemizedOverlay that displays a blue dot for the current user location. This overlay also listens to onTap, which depending on the coordinates of the tap, will try to find metro stations (for which I know the lat/lon coordinates). This is working perfectly.
The stack trace of the crash is:
CODE:.....................
Sometimes it comes from different lines but it always finishes crashing at OverlayBunde.java:42
As is does not mention my code, I don't know what's wrong.
You can get the source code of the MapActivity and the the ItemizedOverlay: http://code.google.com/p/metroparis/source/browse/trunk/src/org/bicou/metro/
The activity class is ACarteStations and the overlay class is StationMetroMapOverlay.
When I add a new item to my ItemizedOverlay the onTap display I have set appears X times, where X is equal to the number of items that I added. So for example, if I add one item and tap it, it the onTap method gets called once, and in the LogCat I get:
02-04 23:28:56.188: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub $Proxy@4394c100 duration=0
If I add a second item and click ANY of the other items, the onTap method gets called twice and I get the following in LogCat:
CODE:.....................
If I add a third item and click ANY of the other items, the onTap method gets called three times and I get the following in LogCat:
CODE:...................................
Any idea why this would occur? I'm running into issues with it affecting other things like removal of items.
I've try to make a mapview with itemized overlay and it's not work. I share my code if anyone see anything :

In my application I would like to mark different spots on a map. What I'm now wondering is if there's a way to use a simple 9-patch image and add the spot's name as text to it or would I need to draw everything myself (including the text) in the draw() method of ItemizedOverlay?
View 1 Replies View RelatedI am trying to display one png (drawable) on a map in about 300 points. I am retrieving the coordinates from a Sqlite table, dumping them in a cursor. When I try to display them by parsing through the cursor, it takes for ever for the images to be drawn, about .5 second per image. I find that to be suspiciously slow, so some insight on how I can increase performance would help. Here is the snippet of my code that does the rendering:
while (!mFlavorsCursor.isAfterLast())
{
Log.d("cursor",""+(i++));
point = new GeoPoint(
(int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LATITUDE))*1000000),
(int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LONGITUDE))*1000000));
overlayitem = new OverlayItem(point, "", "");
itemizedoverlay.addOverlay(overlayitem);
itemizedoverlay.doPopulate();
mFlavorsCursor.moveToNext();
}
mapOverlays.add(itemizedoverlay);
I tried to isolate all the steps and it looks like the slow one is this: itemizedoverlay.doPopulate(); This is a public method in my class that extends ItemizedOverlay that runs the private populate() method.
