Android :: Adding Items To Maps Overlay Does Not Immediately Show On Map

Aug 28, 2010

I can't figure out how to tell my Map to redraw its overlays once I've updated them. Currently the user has to touch the screen before the map is redrawn.

Samsung Captivate :: Way To Have Single Folder Show Received Items / Sent Items Combined?

Jul 21, 2010

Had no problem getting my phone to play nice with our exchange server at work and emails are coming/going fine.

However, there are some configuration items I have a big issue with as it relates to the 'look' of the email (coming from a BlackBerry).

1. Is there any way to have a single folder show my received items and sent items combined? My BB had this and it was very useful.

2. How can I edit the way my folders are displayed at the top horizontal bar? The sidescrolling folder display is awkward, it puts my inbox first (good) but then all subsequent folders are listed alphabetically; it pays no attention to their order on my desktop and also shows sub-folders of other files. Any way to change this?

3. Is there a way to change the way emails show as unread? The difference b/n read and unread is only a shade of grey, and difficult to see outside.

Android :: Start Activity From Overlay In Maps

Jul 22, 2010

I am trying to create a map application and I need to do something similar to what Google Maps does. I want to open show a list of locations and when user taps on them I want to show a dialog.

I was able to do it till here. But now when the user clicks on the dialog that opened I want to show another acttivity with the details of that item that they clicked on.

I tried to start a new intent but it gives me an error.

Here is what I am doing

CODE:...................

Here is the stack trace E/AndroidRuntime( 4985): java.lang.RuntimeException:

Unable to start activity ComponentInfo{com.achie.test.mapssample/ com.achie.test.mapssample.ItemDetailView}:

CODE:........

Why am I getting this error and how can I resolve this and open a new activity?

Also where can I find the source code for the google maps on android?

Android :: Detecting Clicks On A Google Maps Overlay

Jun 15, 2009

I would like to put a bunch of dots on a google map, and have the appropriate listener called when one of them gets clicked.All i seem to be able to find is to get the location at which the click occurred, and then iterate through the dots until I find one that I think matches. Is there no listener for an arbitrary shape, like a drawable? I feel like this might be a Java question more so than android, but hopefully someone can still answer it.

Android :: Phone Maps Support Ground Overlay?

Jun 8, 2010

I have a weather image I would like to use as an overlay in the google maps android api. I would like to achieve the same result that I get from using GroundOverlay in KML files, such as

<GroundOverlay>
<name>myimage</name>
<Icon>
<href>myimage.png</href>
<viewBoundScale>0.75</viewBoundScale>
</Icon>
<LatLonBox>
<north>75.6088</north>
<south>5.0121</south>
<east>182.2805</east>
<west>120.6795</west>
</LatLonBox>
/GroundOverlay>

The above will ensure that the 4 corners of my image stay anchored to the 4 lat/long points listed, regardless of scrolling, zooming etc. Is there a way to accomplish this using the google api / maps provided for android?

Android :: Expanding Overlay Marker On Google Maps?

Jul 20, 2010

I can draw overlay items onto google maps just fine, an image that looks like:
_____
| |
______
/

Where the "/" part is the "pin" that marks the lat/lon on the map and a picture in the middle of it. My question is, is there any way to expand this when the user clicks on it? I'll of course have to change this to some kind of dialog or layout and change it when it gets clicked.

I want to have it smaller like that with just an image when not clicked on, but when it is clicked on it expands over like a second to:

--------------------------------------
| <image> <buttons> |
| <buttons> |
| <some info here> |
| |
--------------------------------------
/

Is this possible?

Android :: Threading - Custom Google Maps Tile Overlay

Nov 4, 2010

I've been stuck for ages now trying to implement threading or background image loading for a custom tile overlay class I've been working on. I'm pretty useless when it comes to Java so threading isn't something I've had any experience with. Basically I have extended an ItemizedOverlay and in the draw() method calculate the tiles I need to display over the standard google tiles then fetch those images with a URLConnection and using BitmapFactory decode them and draw them to the canvas at the correct position on the screen so that the images are on top of the google tiles with about 50% opacity (the custom tiles are cellphone network coverage png's which are used for our web app). I initially got this all working with the tiles loading in the correct places but hit issues with memory and "freezing" while panning so implemented some basic caching and memory management to only store the tiles that are displayed on the map in memory and when downloading a tile store it to SD card.

Then I figured the freezing while panning is due to the blocking nature of downloading the images so, have been trying to implement threading. I created a class that extends AsyncTask to download the images in the background and store them to SD, in the onPostExecute method I then try to draw all the tiles. But onPostExecute never seems to fire, now I know that the AsyncTask has to be called in the main ui thread so tried to debug the execution with Thread.currentThread().getId() calls through out the code. The thread Ids through out is 1 and then 10 for the doInBackground method for the AsyncTask. Now I'm not sure if 1 is the main UI thread or not. In the extended MapActivity class I have, the onCreate method's Thread.currentThread().getId() returns 1 but I'm not sure if the MapActivity class is executed in the main ui thread? Here Romain Guy mentions that the onPostExecute method should have @Override but when I do that eclipse flags it as an error

"The method onPostExecute(Boolean...) of type TileCache.ImageLoadTask must override or implement a supertype method"
So I guess something is wrong there but the only fix eclipse offers is to remove the @Override
So I guess with out post all my source code, the question's I have are:
Is the MapActivity onCreate method called in the main ui thread?
What does the @Override error mean? or why does it show that error
Does anyone have an example of a custom tile overlay implementation with background image loading and tile caching?

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 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.

Android :: Show Dividers After Some Items In Listview

Jun 24, 2010

I'm building a list that is sorted alphabetically. The list should show a divider containing the Letter that the following icons belong to.

I'm using a Cursoradapter that contains the already sorted result from the database. I plan on adding the divider to the list item and set it to visible if the shown letter changes. How do I know that I have a new Letter? Is there a better way then going forward or backward in the cursor and check if the item I show is the end or beginning of a new group?

Android :: Android Maps Overlay OnTap Click

May 5, 2010

Could anyone help me with my below program. I'm unable to put a transparent label containing the contents from my HelloGoogleMaps.java class (Hola, Mundo!) when i click the markers(the android icon) in the map. I would like to have the ontap event do it for different markers here so that that particular location details is popped up. It needs to be in a canvas display. Upon clicking this new canvas label, it should take me to a seperate activity displaying complete details. I'm using the sample program given in the Google Android Website http://developer.android.com/resources/tutorials/views/hello-mapview and i want to extended it to the next level. Import com.google.android.maps.GeoPoint; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import com.google.android.maps.Overlay; import com.google.android.maps.OverlayItem; import android.app.Activity; import android.graphics.drawable.Drawable; import android.os.Bundle;

Android :: ListView Items Won't Show Focus When Touched

Jun 20, 2010

I've got a ListView that works just great, except for this minor annoyance. I can use the trackball/dpad to move up and down my list, and the background changes according to which row has focus. But when I touch the row (click or long click), there's no background change letting me know what's been focused. I've tried setting 'focusable' and 'focusable in touch mode' to true on the rows, but it still doesn't work.

Just in case it matters somehow:

I am setting onClickListeners for each row. The row is comprised of LinearLayouts, TextViews, and a single ImageView. Focusable/clickable is 'true' for each row. Have not specified values for these on the ListView.
Trackable does act funny. I can only move between rows after touching inside the ListView. If I scroll trackball above the first item, it's impossible for me to scroll back into the list.

Android :: Show Info Related To ListActivity Items - Toast - New Page

Sep 28, 2010

I am working on learning Android programming. I am attempting to build an app that shows a list of items, and when the user clicks on an item, it will display an image of that item, as well as information about it. I'm not sure the best way to present this information. Would using the Toast widget be best? Or TextView? Or, is there another way, like creating a new activity, that makes more sense?

After the user clicks on the list item, and reads the presented info, they should be able to return to the list.
