I have an application which is basically a surfaceview, where height/
width is set to fill_parent. I run it on a htc desire, but when I
check the size of the view (or the canvas I obtain), it says 340x533,
so some kind of scaling seems to be done. Also, I load a bitmap, which
seems to be scaled.

I've successfully built a small sample app where the user can add a
appwidget, using the AppWidgetPicker, using the action
AppWidgetManager.ACTION_APPWIDGET_PICK. When I do this, the
AppWidgetPicker takes care of binding my appwidget-id to a provider.
However, now I'd like to load some widgets
What I'm trying to achieve is quite simple: I want to draw a
fullscreen image (RGB_565). On top of it, I'd like to draw a
fullscreen image with an alpha channel. My problem is that I get
terrible performance, around 30 fps. Is there any way to speed things
up? I use a HTC Hero, shouldn't the
I have a ViewGroup where I re-layout the children very often (using
child.layout since I need to change the size). Now, of course I'd like
to use drawing-cache to speed things up.
I noted, in the new SDK, that View.getDrawingCache has an autoscale
argument, which will be invoked with
I guess my real question is: Can I keep the drawing cache for my View,
even if I call onLayout on it?

I need a layout where the children are moving and scaled dynamically
when I move my finger (almost like a Listview, but simply offsetting
the childrens' x/y coordinates won't suffice, they need to be scaled
aswell). Right now I'm calling layout(...) on each child every frame.

I have a custom ViewGroup. Now I'd like it to have faded edges (like
ListViews when you scroll them and such). How can this be done?

I solved this by using
setFadingEdgeLength and setVerticalFadingEdgeEnabled. I also had to

Im currently implementing my own ViewGroup. I send a certain size

ignore it. The children are TextViews. I try to force them to have a
height of 30px, but they are 34px instead. Is there any way I can

I've noticed that OpenGLContext is removed from 1.5. Everybody says
that GLSurfaceView should be used instead. Does this mean that there
is no way to render OpenGL graphics into a regular View?

Hm, exactly what is your question? :)
An animation doesnt actually move the object permanently, it just
translates the Canvas during the Animation. I assume you want your
View to stay where the animation left it? Why do you put the
v.setLayoutParams from a separate Thread? Is that really needed?
I have a small problems with animations. I have a custom ViewGroup
inside of a FrameLayout. Im animating one of the children of my custom
ViewGroup with a TranslateAnimation. The problem is that the View that
I'm animating leaves traces, so it's like the entire screen isn't
redrawn during the

Why isn't is possible to manually set the drawing order of views? It
seems like a pretty big restriction. Is there any thought behind this

is too bad when it comes to animations
I have an animation, from which I'd like to get a transform. Im not
letting the animation play by itself, I just want to get the current

Yeah but why isn't the View redrawn if I call invalidate() from
computeScroll()?

What is the difference between invalidate() and postInvalidate(),

I've been looking around in the framework source and I can get my head
around some things. For instance, in the ScrollView, the animated
scrolling is done by using computeScroll(). To make the screen redraw
(and thus call computeScroll() again), postInvalidate() is used. Why
is that one used,
Okay, thanks! But what about the question regarding invalidate()/
postInvalidate()? Because I tried to experiment with scrolling, and
simply calling invalidate() from computeScroll() wasn't sufficient, I
had to call postInvalidate, even though computeScroll() runs on the UI
thread?
