Android :: Animated Map Overlay
Feb 17, 2009
I am trying to make a map overlay animated much like MyLocationOverlay does. Currently the only things that I can see to make animated are Views but Overlays don't extend View functionality. My next thought was to try to lodge a View into the overlay, but the redundancy makes it seem like this solution is incorrect. I grabbed the android source hoping that I could just look at MyLocationOverlay source and that would let me know how the animation was supposed to be done, but I can't find the source for anything involving maps. If that is available somewhere it would help. Can someone point me to the MyLocationOverlay source or let me know what the paradigm is supposed to look like for animating map overlays?

I like tu use the MapActivity to display some pins. When a pin is pressed i like to open a description. This can I obtain following the tutorial: http://developer.android.com /resources /tutorials/views/hello-mapview. But now I like to put a button on the overlay window. That button should open a detail activity. How can I make this? How is possible to personalize the overlay "info window"?

I would like to make a simple 2x2 widget that displays a canvas that's updated every second - how can I go about doing this? I noticed you can't make the onUpdate() update more than every half hour now, so that shoots down that idea...

Are there simple sample codes out there that demonstrate how to create animated splash screens, similar to Android boot-up screen but not at that level. I'm more interested in application animated splash screen. Is there an easy or common approach to this ?

I want to market an overlay for Android Maps. It will provide the "speed limit". My map will have to query the internet for updates pretty heavily as one travels. Q: Should I just use the "Maps external Library" thing? http://code.google.com/android/add-ons/google-apis/maps-overview.html or Q: Can I somehow make it an option in the normal google-map system that everyone has on their phone?

Is it possible to create an Android activity as an overlay above other application? If yes, please provide me a pointer.

I have subclassed Overlay as LandMarkOverlay (and implemented an onTap(GeoPoint) method).
In the main activity I do this:
setContentView(R.layout.main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
landmarkOverlay = new LandmarkOverlay();
//add the landmarkOverlay to the list
mapView.getOverlays().add(landmarkOverlay);
What else do I need to do so that when the user taps the screen, landmarkOverlay's onTap(GeoPoint) method gets called?

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?

Any good weather apps(or direct sites) with ANIMATED radar that will load on non-Flash Android.Droid-X(until Froyo comes out...for real).I noticed Weather Channel DOES have an animated app that will load but it takes forever for it to load slower than animated radar would load on my Storm(which was relatively quick) but I thought this Droid-X was supposed to be fast. Yeah I know the problem is probably on TWC's side of things as they always seem to be slow.Had Accuweather on the Storm and I had the animated radar saved as a favorite and could one-click to get it.

I LOVE the animated weather widget that is on the HD2, Hero and Evo.I switched to the Nexus One because it fitted my needs better than the others did.Am I missing it or does the Nexus One not have the animated weather widget?I didnt think that not having an animated weather widget would be a big deal, but I am really missing it.

We are doing some prototyping for an Android app and we wanted to use Animated GIFs via webpages to get a sense of animation. Unfortunately, we have found that we can't do that on the Android's browser (or Opera for that matter). I've read some posting saying that this might get fixed but there were never any specific dates. Does anyone have some news on when we might be able to use Animated GIFs in webpages? If not, does anyone have any suggestions on good ways to develop quick animated visual prototypes of apps for Android? In particular, our design folks (who are handling the visual stuff) know HTML, Javascript, J-query but don't know Java and we would prefer to NOT have them learn another language, if possible as this is really just for rapid prototyping.

I have a TextView on which I set an onClickListener.
I assign a Traslate Animation to this TextView, so that it moves from position A to position B in the screen.
The Animation works as expected.
My problem is due to the fact that it does not matter in which position the TextView is during its movement: in order to trigger the "click event" I need to touch the screen only in the starting position (A).
EXAMPLE: Imagine that the TextView is in the bottom left corner and it starts moving toward the top right one. Imagine that the TextView is now in the center ofthe screen. If I touch the TextView where my eyes "see" it (= in the center of the screen), nothing happens. Else if I touch the starting point at the bottom left of the screen (which is a blank place because the TextView has moved from there), the event is triggered.

I just want to display an animated GIF file. I tried and its static only, its not animating. There are other ways like frame by frame or using animation classes.
But I want to know, whether android supports animated GIF image.

Suppose I have the URL for large animated gif and I wanted to make a youtube like activity that displays the animation in a streaming way. How do I
stream in the image?
get it do display with actual animation?
I know ImageView is not the answer as it only shows the first frame.
A bonus would be having access to its buffering status so I can synchronize streaming sound as well -- this is part of a YTMND viewer application. While I could create a service that transcodes the public gif files into a nicer format, I'd like the app to function without additional dependencies.

Just like Twitter for android used to have (they removed it) - I need to display an animated background drawable.
How to I show an image that is actually bigger then the given layout dimensions (without the image being shrink).

In android-sdk-windowsplatformsandroid-8data esdrawable progress_large.xml, the following code is used:
CODE:.........................
If I try to copy this code in my own projects (so I can change the drawable), I get a compile error for framesCount and frameDuration.
Is <animated-rotate> something that can be used? And if so, how?

I'm trying to get an indeterminate progress image to show up in my custom listview row. I tried copying the progress animation xml file into my drawable folder and setting the image source to it, but it just shows a static image. How can I get it to animate, like it would in a dialog box or in the title bar?

The Android the MapView Overlay class mentions two draw methods. One regular, and one for animated overlays.
I have tried to find more information on how to animate overlays and use this second method, but it all keeps coming back to the same forum postings. Can anyone explain how you specify to the MapView that a certain Overlay should be animated? How do you specify the manner in which it animates?
If it's relevant, I'm currently trying to draw pins in the map that update in realtime with streaming GPS locations for objects. I get new data every two seconds and need to tween the locations by having the pins move in a simple straight line between coordinates.

In android 1.5 release notes I saw Animated window transitions.
What is this all about ?
IN my application i want to show trasitions if i go from one activity to other.We can set the animation for both activities and call when one is closing and other is opening.
But problem is when , the current animation will stop when the onCreate of next activity is called ?
Means , when activity is pushed to stack , ongoing animation is stopped. Because of this we cannot show a smooth transition effect between activities.

I have been banging away at this one for weeks and I feel like I have exhausted my research capabilities. I am hoping that someone will see my error in the code posted below. The code is completely functional doing everything I need, but there is a major memory leak. When I try to track memory in the DDMS, the VM Heap tells me that my object count is relatively stable and the used memory is also relatively stable (it comes back down to a similar value after each GC after panning).
When I look at the memory pie chart, the free memory loses over 1meg of capacity with each map pan (overlay reload) and the Unknown memory grows. I have not found anything with the allocation tracker. Functional Summary: I load overlays onto a map based on data I get from polling my server. When I pan the map far enough I clear the overlays and load new ones.
MapFrontEnd.java (snippets): //header info private List<Overlay> overlays;
//in onCreate overlays = mapView.getOverlays();
// here I attempt to fully clean up my old Overlays for (Overlay i : overlays) {
if (i instanceof ParcelOverlay) ((ParcelOverlay) i).cleanUp(); }

I've been trying almost everything and been searching and reading everywhere on the net. I just can't seem to find the correct way of doing this.
I have a MapActivity with a MapView and I want to draw something on an Overlay. I'm overwriting the draw-method, and I can easily draw straight on the canvas using a paint. My problem is I want to merge some circles and afterwards color them. Therefore I want to create a Bitmap and then draw on that. I just don't know what to use. Should I use a mutable Bitmap, a BitmapDrawable or am I simply going in the wrong direction.
The reason I want to do this is because I want to draw some kind of heatmap upon the Google Maps, and I need to merge and blend different circles, so they appear to be just one big blob.

I am searching for functionality which works like the itemizedOverlay on the mapview, only for Imageview. So that I can add items on specific locations on the image and trigger actions on tap of the item. I am building an application for Android where you get Floorplans and on this Floorplan the rooms should be marked and clickable to get more information.

have been dealing with placement of items in the ItemizedOverlay class with the google maps android library, which seems to work just fine. It handles the icon placments and associated properties of the icons that I place on the viewer.As of lately though, I noticed that I loose the satellite view altogether in the final zoom features of the map when I want to get in real close. I thought this would be a real good opportunity to use a blueprint of an area as an overly on the gridded map so that there were still areas of reference when analyzing an area up close. Unfortunately I have not been able to place a bounded region for the blueprint on the map. If I have latitude and longitude values for each corner of where the blueprint should be places, I can't seem to find a method to put this where I want it on the map.The only constructor/method that I have found only asks for a center point and then sizes the object appropriately. It seems odd that this feature wouldn't exist but I can't find anything to hint that it does exist. JFrog "Debugging is twice as hard as coding something the first time. Therefore, if you make your code as clever as possible, you are by definition, not smart enough to debug it."

I have built a simple app that uses a Google MapActivity. On top of the Map, I have 2 overlays, a Marathon Course and the position of a runner. The latter position overlay simply shows an updated blue dot.I update the location of the dot every second but the screen does not refresh. If I tap the scrren then the dot updates. Am I missing some hard refresh call somewhere? My Overlay code is small and shown below. Note that it does go into the draw routine every second and the point is changed.

I am trying to merge two examples from the ApiDemos so one overlay over the other. 1. CameraPreview.java 2. TranslucentGLSurfaceViewActivity.java I guess GLSurfaceView is not really necessary, I saw demos that uses a GL layer as a Camera PreviewCallback, but since I am such a noob at OpenGL, I am kind of lost. Can someone points me toward the light (figuratively speaking)?
