you can see where he's defined a custom widget called ColorMixer.ColorMixer has an attribute named "initialColor" declared in attrs.xml.but getIdentifier never returns anything but zero.Is there something more I should be doing? I want to re-write this code to be completely independent of 'R'

I'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
I've created a combo box control with a edittext and spinner. I'm trying to let the android:prompt attribute be passed onto the spinner, which means I need to catch it in the constructor which passes my the AttributeSet and set it on the spinner. I can't figure out how to get the value of the prompt.
I get back 0, which means it didn't find the attribute.I also did a ta.count() which returned 0. So I'm not getting anything back.My XML simply defines an android:prompt value.
Is there a way define widget default values in the context of an application.

View 1 Replies View RelatedI am writing a clock widget that uses customised bitmaps (so the widget loads the bitmap from the sdcard) Just have a couple of questions regarding how updates work:
1. if i want to display seconds on the clock widget will the widget load the bitmaps off the disk every second or can they be cached somehow so it doesn't reload off the disk each time. or If it does reload a bitmap each second, would this use a lot of power?
2. If i load the customised number bitmaps into a static array and then pass them as bitmaps to the widget would this use less power than just loading off the SD card?
I'm attempting to use a custom Android vertical scrollbar widget that seems to work fine in its own example project, but I am having trouble trying to include it into my project. I've exported a .jar from it to use in my project, but it seems to be a minefield of problems, from duplicate resources, to my XML layouts not able to get at styles inside the library, and errors "inflating class" when reading my XML layout file.How should I go about using the widget from another project in my own?Quite new to Java development (know the language, but not much of the overarching project/package management), so if there's some good text regarding that it would be appreciated.

View 5 Replies View RelatedWith Android, you can define different resources for different phone attribute by naming res directories appropriately. I need to be able to support different layouts for 480x800 and 480x854. I figured I could have one set of resources stored in the layout-hdpi-v4 directory and another in layout-long-hdpi-v4. However, both resolution seem to think that they are long (at least based on the emulator, which I understand may not reflect devices accurately). Is there another way in which I can distinguish between the two resolutions/aspect ratios?
View 2 Replies View RelatedI'm starting to design my object graph for an OpenGL ES 1.1 app on Android. What's advisable when it comes to actually drawing my triangles and controlling their size? Should I store all the vertices in units relative to each other and then multiply them by a value I pass during a draw(GL10 gl)? Would this approach have any impact when it comes time to do frustum culling?

View 1 Replies View RelatedI'm writing an app that will host widgets. The app has custom view (which probably is the source of issue).mView.addWidget() basically just remembers this AppWidgetHostView instance and then mView draws it directly onto canvas. Visually everything is fine.I can see the actual widget. But the issue is with reacting on UI events. Please advise what needs to be done in the parent view in order to correctly trigger handlers in the widgets like onClick().I used standard widgets which normally react on click events. None worked.I also created my own test widget with listener and onClick()is successfully triggered if the widget is added on Homescreen, but doesn't work in my app.mView correctly detects click event and I tried to call widget.perform Click there, which returns false meaning onClickListener is not registered in the widget. But according to source .would call updateAppWidget which would register its onClick listener.

I would like to define each tab's content in a different XML file so the visual editor in Eclipse can be used. That is, without all of the tabs being laid over each other. The visual editor doesn't even seem to work with the XML example provided here: [link text][1]
