Android :: Add TextView/Layout To Map's Overlay / OverlayItem?
Apr 12, 2010
When a marker is clicked on google map, a small square area is displayed with hyperlinks. I guess OverlayItem does not render hyperlinks for its snippet. How to achieve this? Ideally I want to assign a layout with all sorts widgets. Presume I can display a small floating activity window when the marker is clicked, but is this the standard way doing this? The drawback of floating activity window is that if want to click another marker, user has to dismiss the current window first.

I want to have a textview (like a console or output window), which scrolls. I saw on this list that the TextView will not scroll on its own unless I wrap it in a ScrollView. So I did that and it worked. The problem is, it seemed no matter what I did I could not get the TextView to be higher than one line. This was only when it was embedded in the ScrollView, and didn't seem to change whatever I set the TexView's layout_height to.
Here is my layout:

Why doesn't write this program "Hello World! :-)" on my screen? I know how I would do it with an xml-file, but I want to do it like in the following program. And how can I set the coordinates without setting the width and height like with tv.layout(10,10,100,100);?

In a RelativeLayout I have a Button to the right of a TextView. The problem is that the text view gets squished to the left of the screen.I want the Button to be squished to the right and the TextView take up all the remaining space.I can't use 'Fill Layout' on the TextView because the button then gets removed from the View completely.

I am having a bit of trouble with my current application. With a button at the beginning of my app, I send out Intents for two activities, one gets a camera object, and starts a preview screen. On top of that, in a separate layout, there is an activity with a translucent view, which shows a resource image (the user is trying to get the image he is actually taking to align with the translucent image) and a couple of textviews displaying a target phone orientation as well as the user's current phone orientation.
when I update the text value of one of my text views in my onSensorChanged() field, the system constantly reallocates 1.22MB and garbage collects it. I can only assume that this is because it is redrawing the entire layout with the translucent image and the text fields, because if I remove the view containing the translucent image from the layout, my text field updates 10x quicker and I don't have ridiculous heap growing / garbage collecting. I am wondering how to go about getting the text fields to update without redrawing the entire surface. I am very new to UI design, and this code was written by someone else before I took over the project, so I don't understand much of what is going on in the custom view he wrote to take care of the translucent image -- called MyView. I will post the code for the layout as well as the MyView code below.................................

Android:layout_gravity="center" doesn't seem to work the same in a RelativeLayout as it does in a linear one - I would just like both an ImageButton and a TextView to be centered in a relative layout - is there a basic xml code for this?

I have a relative layout with various text view aligned in it.But the alignment goes wrong if value of any textview goes multiline.is there any way to avoid it?
The view required is something like :
Name: Abc
address: 23,abc street,fhjhg apartments,Country
Email: abcdgehfhf@mail.com
address text view has width set as wrap-content
but it appears like:
Name: Abc
address: 23,abc street
Email: fhjhg apartments,Country
abcdgehfhf@mail.com

The layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

Currently I used a map view and placed some overlay items in them
I overiden the onTap function in ItemizedOverlay so that when user tap on the markers icons on the map, some action will perform.
However, I don't know how to know which marker is being tapped so that the related data of the item will be displayed in the screen. How can I do that?

From everything that I've seen and have been reading, I'm apparently supposed to add all my OverlayItems in the constructor, then call Populate().The problem I have conceptually, is that if I'm pulling these items from a database (fed by a web site), then when exactly do I update the items?Also, it seems to me that it's a waste of resources to feed it all the items in advance instead of the ones pertaining to the current location... This seems to be the perfect case to use a ContentProvider, but I don't see anything indicating that one can be used with either ItemizedOverlay or anything else related to the Google Maps API.

I want to be able to get some reference to the curent object being drawn. code...
Above is my draw method and I want to extend the draw method to write the title underneath each item for example. This would require the .getTitle() method from the OverlayItem. Possibly some tracking of objects outside of this method but not sure where to put it....

I am able to display multiple overlayItems on Googlemap, now I want to change icon of any specific overlayItem (to show it is currently selected event). I want to do it through navigation buttons (next, previous) as on Google maps.
I am using StateListDrawable to display icons for OverlayItems. code...
Now my question is how do I change the state of any overlayItem/Icon on map when user click on one of navigation keys?

I have a simple overlay for a Google Map: http://pastebin.com/Rg8miMSh and I add/remove items on it depending on the zoom level. After removing/adding I call populate on the overlay and invalidate on the map view. Everything works just fine, except 1 glitch: after an item was removed, if I tap its location onTap is still triggered and because the OverlayItem is not there anymore i get java.lang.ArrayIndexOutOfBoundsException in com.google.android.maps.ItemizedOverlay.maskHelper(ItemizedOverlay.java: 562) (full stack trace - http://pastebin.com/KThn4ZLE )
Anyone knows why this is happening or how to fix it? Initially i called clear and added all items all over again which didn't seems to cause this problem. However having many items this was becoming a performance issue. Adding/removing only the difference works much faster and I would like to keep this method.

I currently have implemented an overlayitem that shows an icon for geopoint on a map application in Android. When the icon is clicked, it brings up an AlertDialog from the onTap method below.Does anyone know how to display a map message bubble directly above the icon overlayitem with 2 callout buttons one to the left of the title and one to the right of the bubble? Does anyone know how to make the overlayitem draggable so I can press and hold it and drag it across the map. I am trying to duplicate the draggable icon behavior that's available on the iPhone.

Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.
I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

I would like to further annotate the custom markers I have placed on a MapView (using ItemizedOverlay) by displaying a simple text label that appears for a particular item when the onTap event is fired.
This is a trivial exercise in the Google Maps JavaScript API and in MapKit on iPhone, but it is not obvious to me what the best or easiest way to do this is on Android.
