Is there a way to define xml layout resources in a modular way? I am building individual 'panels' through code only, it would probably make sense if each were defined in their own xml file, which I can pull at runtime, something like the following pseudopod: Code...

The 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?

View 1 Replies View RelatedI'm building a jar so that other developers can use the view I create in their Android applications. I'm wondering if it is possible to use a layout resource in my jar so I can build the layout of my view or if I need to build up my view programmatically. Similarly, can I include image resources in my jar file?

View 2 Replies View RelatedIn native development, you can produce libraries - .so, .dll etc - that other libraries and programs can share.In Java, you can put your code in a JAR in the classpath and other programs and libraries can use it.So how can you do modular programs in Android? I get the impression from the documentation that each APK is a self-contained island. Can different APKs share code?
And how does installation work when you have these external dependencies? Can you specify that you rely on library that is not in your APK and get it installed too?If you can't have 'dynamic linking', can you have 'static linking' by developing your shared code and somehow putting the equiv of a JAR into each APK that requires it?
In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?

I even searched for it,but of no use. Any one help me, I need it very badly.

View 1 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 RelatedI'm reading the android developer docs on creating custom components and one thing that's unclear, is whether you can define the layout of your component using xml and then reuse that across class libraries. like, say for instance, I want to create a class library called myComponents, and in there i want to have myTehAwesumsWidget or whatever, and i want the layout to be defined in xml, can i include that xml in the referenced class library?
View 1 Replies View RelatedWhile developing for Android, I am unable to open more than one main.xml file in an Eclipse editor at a time.Each time I open one, it simply replaces the editor (tab) of the first main.xml with the new one, instead of opening a new tab - even if the contents of the existing tab were unsaved.Even stranger, I can open multiple main.xml files from different projects with no problems.This only happens when they're within the same project.

I am using eclipse 3.5 with the ADT plugin.when I view layout xml files, i get two tabs in the view the source code view and a graphical view.the graphical view almost never works for any of my layouts.it usually shows "NullPointerException: null" at the top and nothing else. when it does work, it often does not match what i get in the simulator or device.it seems like this thing simply is not ready for prime time; although the idea is very cool.has anyone else had much success with it?
