Hi Dirk
I dont have a problem with updating my widget, either setting text,
visibility or intents on all the different imageviews, textviews etc
within my widgets whenever i want all works fine.
The issue is more fundamental than that: the remote views object is
inflated from a static compiled XML file in the contructor:
RemoteViews (String packageName, int layoutId)
I want to know if it is possible to build a remote views object in
some other way than from the XML file, because I dont know until run
time exactly how I want to lay out my RemoteView.
Ideally I would like to be able to create a blank remote views object,
then add items such as layouts, imageviews and text views to it
dynamically.
The only other contstructor available is
RemoteViews (Parcel parcel)
But it is not clear if that will do what I want, I need to look into
Parcel to see what it is used for.
Kostya,
HTC do it in Sense because they have their implemented the own home
screen; whilst it can host normal AppWidgets, they have written
special HTC widgets which are not standard AppWidgets at all, but
greatly customised to work with their home screen. Hence they can
support animation, touch scrolling etc.
They have also customised how the user adds these special widgets,
which is why you can have multiple options for Clocks, Calendars etc
under a single Clocks or Calendars heading.
In normal Android, you have to build an AppWidget for every size you
want, and specify the size beforehand.
I would love to get hold the HTC homescreen API, so many cool things
there...
