Android :: How To Scale Markers And Set Shadow And OnTap Correctly

Nov 17, 2009

I'm scaling markers on a MapView with the following 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 started programming with LibGDX and i think this is the best library for Android Development but i have one problem. The Problem is with other screens and sizes.

Here is the screen:


As you can see there are pixels on the bombs on the smaller screen but on the bigger on there is no pixelization. How to solve this problem? How to make images more smooth not pixelated.

Android :: ItemizedOverlay.onTap() Imprecise?

Feb 15, 2010

I'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.

Android :: ItemizedOverlay Using Both OnTap Methods

Jun 15, 2010

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).

Android :: Change Drawable OnTap?

Aug 3, 2010

I have an Overlays class named picOverlay which extends ItemizedOverlay<OverlayItem> that uses a drawable named ''overlay''.

I'd like for my application to change the drawable to let's say ''overlay_hover'' when the user touches the overlay.

Can I do this in the onTap method? Can someone enlight me a little bit on how to change the drawable that I'm actually touching?

Android :: Launching Activity From Overlay OnTap

Feb 10, 2009

I am wondering if I am going about this problem the correct way.I am making an app that places overlays on top of google maps.When you click on the overlay it should launch a dialog type window that will give you options on what to do with that overlay.It is the line startActivity where the app throws an exception.I did the setFlags because an error message said it was needed because I was trying to start the Activity while outside an Activity.That makes me think I am going about this wrong.I have 'MyActivity' listed in my manifest so I don't think that is the issue.I have searched for this problem on the internet and I can't seem to find anyone else running into this so that is another reason I think I may be trying to do this the wrong way.

Android :: Starting Activity In Overlay OnTap?

Feb 10, 2009

I am attempting to launch a dialog type window when I click an Overlay that has been placed on google maps. I thought the way I would do this was Override the onTap() method, create an intent, and call startActivity on that intent as follows:


It looks like the program throws an ActivityNotFoundException when executing that last line. The exception reads that if you try to start an Activity while you are not in an Activity you need to set the FLAG_ACTIVITY_NEW_TASK flag which is why that line is there. I have included MyActivity in my manifest.

'context' is passed to my class constructor that extends Overlay and is the MapActivity that I am using to display the map.

Android :: ItemizedOverlay Adding Items And OnTap?

Feb 4, 2010

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$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:


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:


Any idea why this would occur? I'm running into issues with it affecting other things like removal of items.

Android :: OnTap Display Toast Or Message

Jul 13, 2009

I looked for any information about onTap event processing for itemized overlays in this group. There is a lot of useful information but I could not find the answer to one question.

The tutorial by Mark Murphy on itemized overlays,

describes how to generate a Toast message whenever an onTap event occurs. In his case, the custom itemized overlay activity is included in the main activity. In my case, it is not. My custom itemized overlay activity is included in the application package as a public activity.

This means that the line Toast.makeText(NooYawk.this, items.get(i).getSnippet(), Toast.LENGTH_SHORT).show(); will not work "as is".

I have had trouble in correctly identifying the context for the Toast. Attempts to use the main class' (the one calling the custom itemized overlay class) context have not worked. I would appreciate it if anyone could suggest how I could resolve this issue. Incorporating the custom itemized overlay class in the main class is not a desirable option.

Alternatively, I would appreciate any suggestions for generating a display of the title and/or snippet information for markers on a map.

The onTap event works fine (Log.i statements in the onTap method display the correct information for each marker tapped)

Android :: Overlay OnTap Not Working After Back Button?

Jul 29, 2010

I have several Overlays drawn on a MapView with ItemizedOverlay, and an onTap that works when I first start my app. However, if I press the Back button on the Android then start my app again the onTap does not work at all. Other touch sensative operations work fine, like long press on the map and several face buttons. It is also fine if I press the Home button on the phone then go back into my app, so its only on the Back button. It will also work if I first open another app like the Maps app, then go back into my app, acting like a reset.

Overriding the onBackPressed method to move the task to the background also does not work, does anyone have any ideas what would cause this? It happens in both the emulator and on a real device.

I don't know if it will help but here is the relevent code:

Android : Reading From XML / Need To Create Overlay Markers On Map

Jun 27, 2010

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.

Android :: Is Shadow Mapping Possible In OpenGL ES 1.0?

Nov 25, 2009

I've tried casting shadow following this tutorial (which uses Stencil Buffer method): The result is a cool shadow effect. But it depends too much on geometry and thus not very flexible. Then I found a much easier way to do shadowing here: But it uses ARB_depth_texture and ARB_shadow extension. So I bet it can't be used with Android's OpenGL ES 1.0. I've tried googling for "Shadow Mapping" and "OpenGL ES" but still can't find a good tutorial. Can anyone recommend me a good place/site I can study for this please?

Android :: Shadow On Top Of A Layout On ActivityGroup / Fix It?

Jul 16, 2010

I'm trying to give my first steps on working with ActivityGroups. To be more specific, I have a parent activity with a layout containing several buttons, and another layout below them in order to add other activities' layouts by means of the "addView()" method. Well, everything works fine in functionality terms; but I'm experiencing a weird behavior inside the layout where other activities are kind of loaded into. A black line along the top border of the layout plus a slight shadow do appear when I run the application on the emulator. I have tried to play changing the paddings, margins, etc. with no success.

Has any of you experienced such weird behavior?

Android :: How To Return Location Pressed To MapActivity From An Overlay OnTap Method

Aug 30, 2010

I have an activity that has a button which opens a new MapActivity to select a location by tapping on the map.

The map has an overlay that overrides the onTap method to get the location but I want to return that location to the previous activity but, I don't know how to return the geopoint to the mapactivity in order to call the setResult() and finish() methods, because I can't call them from the Overlay.onTap method.
