Android :: Custom Widget Styles / How To Put Into Namespace?
Sep 21, 2009
In the ApiDemos, there is a view example called Gallery1 which declares a custom style in attrs.xml.I want to do the same thing for my widgets, but using a different namespace. However, as soon as I replace the android: namespace with something else,Unable to find attribute? Why does it look for an attribute I am about to declare? Isn't the point of this file to be able to name your own custom attributes?It's interesting to note that it works if you do not supply a custom namespace, but just an attribute name.

I am calling a web service which has the following request format.
CODE:............
Now when I call the web service I get the following error SoapFault - faultcode: 'a:DeserializationFailed' faultstring: 'The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://test.com/2009/08:data.
The InnerException message was 'Error in line 1 position 463. Element 'http://test.com/2009/08/ DataContracts:InFields' contains data of the 'http://test.com/2009/08/ DataContracts:anyType' data contract. The deserializer has no knowledge of any type that maps to this contract.
Add the type corresponding to 'anyType' to the list of known types - for example, by using the KnownTypeAttribute attributre or by adding it to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details.' faultactor: 'null' detail: org.kxml2.kdom.Node@43bcb040
The Request sent is has i:type="n0:anytype" in each tag which is creating an error in server side. How do T remove the attribute from the XML tag of the request XML for example <n0:ExServiceDataField i:type="n0:anyType"> should be as <n0:ExServiceDataField>

If you find that the "android:" attribute prefix is cumbersome and reduces the readability of your Android XML files, you might want to try changing the prefix from android to _. If you do it via the Eclipse XML editor, it seems like you have to perform 2 find/replace operations with regular expressions. This is itself a cumbersome task, so you can automate it:
1) Download AutoHotKey, which lets you write a script to send keys and mouse clicks to a program. I believe that AutoKey does the same for linux.
2) Write a script to tell Eclipse to perform a find/replace, scope is all, wrap search, regular expressions on, 1st find expression is (xmlns:)android, 1st replace expression is 1_. 2nd find expression is (s)android: and 2nd replace expression is 1_:. I also added in format and save commands, so my AutoHotKey script is:
CODE:.......
The result is a single-keystroke (Ctrl-Shift-a) to change a layout file from:
CODE:.................
to
CODE:........................

In hierarchy viewer there are several IDs as shown above, for example "id/timepicker_input".
But I can't find a respective timepicker_input - ID when typing
myNumberPicker.findViewById(android.R.id. ...? );
So how to access these Views by their ID?

I didn't find a sufficient answer to my problem in any posts, if there already is one, please excuse and point me to it, thanks. I made 2 projects. project 1 hast an activity that binds to a service from project 2 on a button click (all just for testing).
How can I make project 1 know (import) my TestInterface (from TestInterface.aidl out of project 2) for usage in: "TestInterface mService = (TestInterface) TestInterface.Stub.asInterface(service);"
without adding project 2 to the build path, because if I'd have an installed service without the project code, I couldn't do it this way, too...?? I read in one thread that TestInterface.aidl should just be added to project 1, too, but if I do this, in DDMS enforceInterface() complains and seems to just see/use the interface from project 1 and it doesn't work.
2. issue:...............

I 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.

I'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.

instead of referring the custom widget by a fully qualified class name, is it possible to map with a shorter name. Like it happens in ant custom tasks (though properties file).

I can add children just fine, but I'm never getting my custom onDraw() being called. dispatchDraw() gets called, but that seems to have a different canvas (the one that's within the padding. I need to draw on the whole layout area). Is there some flag that needs to get set to get onDraw() called for the layout?

I have defined custom views in the various layout .xml files. However, all the layouts are using the Linear Layout - put the content would vary.
I would like to create my own widget tag something like <com.mypackage.MyLinearLayout />, I would like to pass the layout as a param to the <com.mypackage.MyLinearLayout layout="@layout/simple.xml" />
How to define new attributes to the custom widgets ? Simply defining a getter/setter method would work or is there any other references.

I have made a custom widget, very similar to JTable in Swing. It is not editable, and all data is replaced at once, allowing easy checking for the widest item in each column & custom col sizing at replace time. It is a subclass of LinearLayout, filled with re-usable TableRow Objects, sub-classed directly from View.
TableRow is both Clickable, focusable, & focusable In Touch Mode. TableRow overrides onDraw(Canvas), calling super. It draws the first column in Black with Lt gray underneath. If the TableRow isFocused () , then a filled rectangle is drawn, before the rest of the cols (left or right justified based on data type), and borders. Where do I get the color, orange, to draw the filled rectangle indicating focus? android.R.drawable.list_selector_background seems to be a pointer, value 17301602, not an actual color. Placing any real Color in my code draws things fine. Is this 17301602 transparent or something? Am I doing this wrong, or do I just need to know how to fine the orange?
