Wiki for HOW TO create a scrollable widget.

[Koxx]

Hi,

Ander and me would like to create a wiki to teach users about
scrollable widget creation.
Any prefered place for this ?

[Koxx]

I think the best place is the Launcher+ Google code page because it
will stay the base project page.

So I create pages :

- How to make your own Home with scrollable and animated widgets
http://code.google.com/p/android-launcher-plus/wiki/HowToHome

- How to make your own Widget with scrollable and animated support
http://code.google.com/p/android-launcher-plus/wiki/HowToWidget

- List of alternative Home support
http://code.google.com/p/android-launcher-plus/wiki/HomeSupport

I hope everybody have write permissions to complete those pages !

[Koxx]

Nop, nobody have write access :(

Finally, may be not the best place :(

any other idea ?

Hi!

I am missing scrolling widgets like those from HTC Sense on my phone.
Recently I have decided to spend some time and wrote one. Then I find
out that is not so simple because of stock home/launcher does not
support this. I think this initiative to do this framework across many
custom launchers apps is superb.

I would like to see that HowTo make a scrollable widget page -
done :)
It would be great if it will also target newbie android developers
like me. (just installed SDK and did Hello world).

Regards
Inermis

Hi,

I already published a very simple example here :
http://code.google.com/p/simplescrollablewidget/

I know that we should publish a How To, but I don't have so much time for this :(
And Launcher devs doesn't seems to have time too.

I you want to write something, I'll be very happy to publish it.
I really think if you start from my simple code sample, you should be able to do something in 5h.

ciao,
Francois

If you send me your email, I can allow you as publisher.

Francois,
I tried running the example code you posted on here - it runs fine in
ADW but LauncherPro will not run it. The AppWidget will come up but
it stays blank and the listview does not display. Running the same
version of LauncherPro, however, PureCalendar will work just fine
(with scrolling.) Any thoughts or recommendations?

Thanks,
Adam

It looks like the ACTION_READY intent is not sent. What is
PureCalendar doing different to get the ACTION_READY intent to be sent
to it?

[Koxx]

ACTION_READY is normally always sent to every widget by the Launcher
after each Launcher redraw (after a screen rotation or widget
insertion for example).

Be sure that 'scrollable widgets' is enable in your Launcher settings.

If you really don't manage to get it, I advise you to look at the code
of Launcher+ or ADW.

[Koxx]

I advise you to send an ACTION_SCROLL_WIDGET_START when you finish the
widget configuration.

[Adam Becker]

I tried that (in a round about way.) and it seems to have done the
trick. Thanks

[Francois DESLANDES]

Good !

If anyone need another code sample here is my opensource widget.
Thx everyone for the samples

[Koxx]

Thanks for this new good code sample :p

[Stephen]

Hi and thanks for the great code samples.

I'll admit as a beginner this has been pretty vague, but I have
managed to implement my own scrollable widget.

The only question or should I say problem I have is :

How do you requery your dataprovider so that the listview will be
rebuilt with the new data? i.e. onclick of a button?

I have tried recalling the ListeViewManager.onAppWidgetReady() method
which creates the ACTION_SCROLL_WIDGET_START but I never see the
DataProvider queried again.

I have set my ACTION_SCROLL_WIDGET_START intent Extras to allow
requerying since the cursor I'm returning is an SQLDatabase cursor, as
per the LauncherIntent.java class commenting.

/**
* Allow or not contentProvider requery
* - disable requery for simple MatrixCursor (not handled
by Android)
* - enable requery for SQL database Cursor
*/
public static final String
EXTRA_DATA_PROVIDER_ALLOW_REQUERY = PNAME
+ "EXTRA_DATA_PROVIDER_ALLOW_REQUERY";


So I'm at a loss :(

[Florian Sundermann]

HI,

here's a sample to requery data from my ContactWidget:

public static void notifyDatabaseModification(int widgetId)
{
Uri widgetUri =
CONTENT_URI_MESSAGES.buildUpon().appendEncodedPath(Integer.toString(widgetId)).build();
Log.d(TAG, "notifyDatabaseModification -> UPDATE
widgetUri : " + widgetUri);
ctx.getContentResolver().notifyChange(widgetUri,
null);
}

Florian

Hi Florian,

Thankyou for a quick response.

I actually discovered that late last night after trying to compare how
your widget could automatically update and mine couldn't.

I really should have read up on ContentObservers and ContentResolvers
and not just ContentProviders.

My widget is now successfully updating thankyou.

I did notice one funny thing that I couldn't find a solution for from
your example.

It's my understanding that after the ACTION_SCROLL_WIDGET_START is
sent to the Home Launcher (ADW,LP,HPP) , the Home Launcher is
responsible for creating and registering a ContentResolver which
resolves back to my DataProvider.

I've found that the ContentResolver connects to my DataProvider and
everything works the first time I run my app. If I delete the widget
and recreate it the Home Launcher's ContentResolver doesn't find my
DataProvider???

This is the only hurdle I have left.

I really appreciate your help guys :)

Regards,

Steve.

Solved, but thanks anyway.

I had done something silly in my ListViewManager class.

When I was putting Extra content into my ACTION_SCROLL_WIDGET_START I
forget to append the appwidget Id to make for a unique intent.

Because I hadn't the intent would go out initially and then the second
time around I guess Android OS didn't send it since it was identical
to the one my previous instance of the widget had sent out earlier.

Correct me if I'm wrong as this is all new to me.

Thanks again! I'm scrolling AND updating now!!! WHOOHOO

Next is animation then lookout HTC Sense UI!!!

Not to keep spamming this discussion I thought I'd offer a link where
I've documented a little on my experience. Nearly like a guide.

Thanks again to all those who made this possible! :)

Hi @ all

I've updated my scrollable contact widget to use the new API so if
anyone is interested in a sample there it is ;)

I made a scrollable widget too used your code as a reference:

Steve,

It looks like your link is dead.  Any update?
