I am trying to setup a selector drawable in my asset file like this: * 2 different images for 'on'/'off' mode in rest mode (i.e. it does not has focus) * another 2 different images for 'on'/'off' mode in focus mode (i.e. it has the focus). In my case, the rest mode works, but the 'focus' mode does not. Can you please tell me what am I missing in the focus mode? Code...

View 1 Replies View RelatedI'm having a bit of a problem with a custom button style. I have the button states (9-patch drawables) set up in a <selector> drawable. The style I'm going for is a button that looks like it gets pushed down, i.e., you can see the front edge of the button until you press it. It works fine for the button itself, but the contents of the Button (or ImageButton) don't move when pressed, even though I have the 9-patch areas set up to move the content area for the depressed button states. It seems like it's keeping the same 9-patch areas no matter which image it's showing.
Here's an animated GIF to help make the problem a little clearer, since I'm awful at explaining things: http://www.crappytools.net/button_problem.gif The button moves when pressed, but the icon inside stays still. I played with the Draw 9-Patch utility, and it shows that the content area in the depressed image should be shifting downwards like intended.
I know how to put the icon on each tab, that is no problem. I also ran across this : Stack Overflow thread on pretty much same thing I followed one of the links from that question, and found this Pretty much, it said use a selector defined in the xml, sure, did that. But there is no id associated w/ it so I am not sure how to get the selector function as a drawable so I can use it as the icon for the tabs. Maybe I am going about this the wrong way.. But this is what I have, and obviously missing something.

View 5 Replies View RelatedI'm working on an application using the SMS apis for android. The receiving end is an embedded unit that only supports 7-bit encoded SMS and the string I'm sending consists only of symbols from this particular alphabet which makes you think that Android is going to send it encoded as 7 bit. But that is not the case.Therefore I'm searching for a way to specify what encoding to use. See below for what my code looks like today. The method gsm7BitPackedToString turns a byte-array to a 7-bit string, i.e. the string only consists of 7-bit compatible characters and is copied from the internal android api. Code...
View 2 Replies View RelatedIs there a way to define set values (i.e. 0%, 25%, 50%, 75%, 100%) for the seekbar widget that enables the slider to "snap" to the nearest set value? For example instead of allowing the user to position the slider at an percentage through 0-100, instead the slider can only ever be positioned at one of the five set values? While were on the subject is there an easy solution for positioning the seekbar vertically, I'd rather not hack through the seekbar source code - but I fear I may have to!

View 1 Replies View RelatedI would like to create a widget that can reads its attributes from an XML file onCreate. I've created a Custom Button that extends Button widget. I would like to define its layout and styling in an XML, such that the widget can be reused across different views, with the same styling attributes. The notepad sample code does carry some pointers to this problem, however, it defines a XML layout with the component as View, inside LinearLayout, which is not really what I'm trying to achieve here.

View 1 Replies View RelatedI'm currently exploring Broadcast Receivers and Broadcast Intent. There are some aspects of the tutorials which are ambiguous to me. To my knowledge this is how the process works. I can broadcast an intent from my application and any receiver on the phone can act on that intent as long as the actions match. I can register a broadcaster receiver on anything that extends Context and when I do so I must provide a filter which will allow the receiver to act on one or more intent actions.The part which confuses me is defining a receiver via the manifest. Must the name of said receiver match a class name? Why should I ever define an intent filter with an action in the project manifest if I always have to provide another intent filter when I register my receiver in code?
View 1 Replies View RelatedThe android docs say that it adds the runnable to the queue and it runs in the UI thread. What does this mean? So, for example, the same thread I use to create my layout is used to run the Runnable? What if I want it as an independent thread that executes while I am creating my layout and defining my activity?

I have 2 questions regarding a ListView in Android:
How can I get the color of the listview's focused row ? I tried to use the ListView.getSelector() method, which according to its documentation should give me what I'm looking for, but it's giving me a Drawable object which I don't know how to retrieve the color from (if possible...).
How can I set the color of the listview's focused row ? Here I tried to use the setSelector() method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...
When using the "selector" to specify different images for buttons for different states, such as pressed, focused etc, do I have to write an xml file for each button? I have about 15-20 buttons in my app, so was wondering if there is a way to write just one xml and refer to parts of it?
