Android :: Scale Map Markers By Zoom Factor?
Aug 19, 2010
I have lot of markers on my map. Zooming in each marker shows me a position. but zooming out the markers are overlapping each other and it is more difficult do determine the position of a marker.
Is there a way to scale the marker image depending on the zoom factor?

I'm scaling markers on a MapView with the following code
CODE:.........
And:
CODE:.............
Which works, but the shadow below the marker has wrong offset when scaled. Also; i override the public boolean onTap(int index) in ItemizedOverlay to detect taps on the markers, but it seems inaccurate. I can click some range outside the marker and still trigger onTap...

I have done my fair share of google searches for this and have come up empty.
I have a set of marker(25) that are being displayed on a MapView. I would love to be able to have it zoom to a reasonable level to make the markers readable.

I'd like to know if there is already a way to know from a given set of markers, the zoom I should apply to the map or do I have to do it my self? (this depends on the resolution so i expected to find it in MapView because it knows its boundaries.

I wanted to create an gallery with images.The images within the gallery should be zoomable and pannable. I could able to pinch-zoom an image but could not able to set zoom limitand prevent the image from being panned off the screen. I used the following code to zoom an image:http://code.google.com/p/4chan-image browser/source/browse/src/se/robertfoss/MultiTouch/TouchImageView.javaspec=svnd3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5&r=d3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5 First approach : I used TouchImageView to supply images to gallery, this allows me to pinch zoom but can't scroll the gallery. i.e I cant differentiate between 'single tab event' and 'tab to scroll event'

Along with Android being 'open', what about some standardized form factors? Would this help the 3rd party market peripherials? I hope Google, with the Nexy, keeps the form factor so that the Nexy 2 will be the same. That way we get more, and possibly more interesting devices from 3rd parties.Not sure if form factor is the right term to use.

removing the g factor from accelerometer readings. I am using SensorEventListener with onSensorChanged() method for getting Sensor.TYPE_ACCELEROMETER data. I need only pure acceleration values in all directions. So at any state if the device is stable (or in constant speed), it should give (0.0,0.0,0.0) roughly.
Currently, depending on its pitch and roll, it gives me variable output depending on the g forces acting on each axis. I hope there is some formula to remove this, as I also get orientation values (pitch and roll) from Sensor.TYPE_ORIENTATION listener. I had used some but didn't work.

I have a project which I want to split into a paid and a free version. I do not care to double my management of the res/ folder and would even like the Android Manifest.xml to be the same file except for the package line. Worrying little about hacking (at this stage - my app is not copy protected anyhow so other avenues of vulnerability are already open), it might be sufficient for me to have all the logic in the free app, and to enable/disable functions based on the app's own package info. What strategies have others used in this regard? I have soft-linked the source from a new Android Eclipse project folder tree to the existing one (the new is to become the paid version and the old one will become the free one with some logic paths being conditionally stubbed at runtime), reserving the new source file hierarchy in the new one to the sole purpose of containing an My Main Activity.java file (as it will need to be in a different package- folder than the one for the free app's). But the res folder appears as though it might be more difficult.

The whole idea of the EVO 4G is being able to take advantage of the faster speed for internet/videos/applications etc. Looking at the intended coverage map for the next year or so it doesn't appear the 4G network will cover my home area. While the network will be in the NYC area sooner than later, I only spend 25 hours a week in the city, and when I get home I won't be able to take advantage of the EVO network. It remains to be seen how long it will take Sprint to roll out this network to other cities in the surrounding suburbian areas.Correct me if I'm wrong but, if the device doesn't connect with the 4G network, it defaults to a 3G network? If that's the case, then switching to a device with limited usage for me personally doesn't make sense until they get up and running in more areas, which I imagine will take at least 2 years.

On my app I will be reading in from an XML file thats formatted something like this
<database> <db1>
<db> <name>name here</name> <street>street here</street> <long> longitude here</long> <lat> latitude here </lat> </db>
<db> <name> new name here </name> <street> new street here </street> <long> new longitude here </long> <lat> new latitude here </latitude> </db>
</db1> </database>
With this information I need to create Overlay Markers on the map (using latitude and longitude) and when they're clicked on I need it to display the name with the address. Depending on the conditions of where the map is, the number of markers will be different so I need a dynamic model for reading in these markers.
If I were to use Document methods like getElementById(String name) then I couldn't call getElementById("name") because it would likely try to call just the first <name></name> or give an unintended result.

Using Google Maps on Android does anyone have any ideas on how to load only markers that would be displayed on the current screen? I'm thinking about sending a request to a web service that returns the lat/lng for the relevant markers. But what would the parameters be that I could use to calculate if a given lat/lng is within the screen?

I'm trying to draw on a map using markers. The problem I'm having is when I try to add lots of them, then I can't get it to run. To illustrate my problem, let's say I want to draw a square made of 900 smaller squares (30x30).I'm trying to add the markers to an itemizedoverlay, then drawing it.
Code:
public class MyItemizedOverlay extends ItemizedOverlay{
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
private Context mContext;
