I would like to display all resource drawables in a list so that the user can select one. Is there any way to loop through all R.drawable items so I don't have to hard code them into my program?

I am trying to modify this example:
http://developer.android.com/resources/tutorials/views/hello-gridview.html
But instead of displaying images that are resources, I want to display Drawables that I currently am storing in a List.
Can anyone instruct me on how I would modify
code...
To display my drawable items instead?
When I add drawable resources to my project they do not show up in the list of drawables in the Reference Chooser. I checked the R file and there are references for the files.
I have tried refreshing the project, cleaning the project, and fixing project properties and nothing seems to help. Sometimes a couple will randomly show up in there, but not all of them.
The only consistent way I can get them to show up is to restart Eclipse.
Further findings:
After some trials, I found an other inconvenient work around to he issue. Turns out when importing multiple files into the project at once, Eclipse will only add the last one imported into the reference chooser. So when I imported my images one at a time, they all show up properly!
Like I said, inconvenient considering the amount of images I have left to import, but maybe with this new information it may help nail down where the issue may be and a possible fix.
Does setImageResource() in ImageView also draws the image instantly on the screen or does it require any other function call? i need to display the image as soon as i set the resource.

When I have a ListActivity and an Adapter how does Android handle a list with 200 elements.
Does it try to load all of them directly how does it wait till the user scrolls and then renders those elements?
Do I have to worry with performance when a list is too long?

I never do graphics type programming. I'm designing a screen that will need to look good on all phones, and all resolutions. It's for displaying in a list view, and there will be a small graphic for the summary view, and a larger graphic for the detail view. Normally I use a 32x32 (res 72x72ppi).png for the summary view which looks good on my G1. The second image is for the detail view and it basically should fill the entire width of the screen (roughly, it's ok if it doesn't use the entire width as long as none of it is chopped off). The size I use for my G1 is 468x60.
So, the question for the guys that really know this stuff is: What sizes do I need to make these images to support all screens and densities with the fewest number of images? I know that the answer is a little subjective, but I remember seeing a post with a link to a page that recommended 3 different images for the different screens (and it seemed to make sense when I read it), and I think but don't remember for sure that then you would need 6 layouts to support those with both landscape and portrait orientations.
I have the Uncertain number of GeoPoint, i want to display them all on the google maps. I don't know how to do it.

I have an XML resource file:
<resources> <section>
<category value="1" resourceId="@xml/categoryData1" />
<category value="2" resourceId="@xml/categoryData2" />
<category value="3" resourceId="@xml/categoryData3" />
</section> </resources>
Using XmlPullParser, on the START_TAG, I can use:
int value = parser.getAttributeIntValue(null, "value", 0);
to get values 1, 2, 3...however:
int resourceId = parser.getAttributeIntValue(null, "resourceId", 0);
doesn't work...it just yields the default value 0, or whatever I change the default value (3rd parameter) to be. Does anyone know what I am doing wrong or if this is possible?
I am just getting started with the Android SDK and I had a quick question. I am trying to set up a ListView with a rectangle of color on the left and then a bit of text for each row. I also want to make it so I can click each entry in the list and open a new activity to display some information (similar to the contact list).
