Setting height of ListView dynamically in run-time

 hi

I want to set the height of a ListView during run-time of my
application. It seems that setPreferredHeight(int) doesn't do this job
and I can't find any similar function.

Did somebody already do something similar?

Thanks,
Patrick

Setting height of ListView dynamically in run-time

I haven't tried this, but here are two ideas:

1. It's possible you need to call requestLayout() on the ListView (or 
possibly the ListView's parent) after calling setPreferredHeight() to 
affect the change.

2. It's also possible that you really need to adjust the height field of 
the LayoutParams for your ListView (obtained through getLayoutParams()), 
then call requestLayout(). Check out the Layout section of the View 
class documentation to see what I mean:

 http://code.google.com/android/reference/android/view/View.html 

If either of those work, let us know!

Setting height of ListView dynamically in run-time

 Hi Mark,




this is the one that works! Here a small code snippet:

AbsoluteLayout al = (AbsoluteLayout)
findViewById(R.id.attachment_layout);
ViewGroup.LayoutParams params = al.getLayoutParams();
params.height = 400;
al.requestLayout();

where the height is specified in "px"

Thanks!
Patrick

1. Drawing scaled bitmaps on a SurfaceView -- no antialiasing

Hi all,

I'm sorry if this topic has been brought before, but all my searches
on the web and this group did not help me.

I'm currently developing a little game with th Android SDK, and use hi-
res bitmaps that I resize accordingly
to match the device's resolution (letting the system do it for me is
not "crisp" enough).

I use a SurfaceView, on which I paint in one pass a canvas filling the
whole surface. The paint uses
setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN)) to allow
masking.
Beforehand, I retrieve various bitmaps -- which are resized at
initialization with createScaledBitmap() and put in a cache --
and I apply the bitmaps with a paint on this canvas, before drawing
this canvas on the SurfaceView.

My problem is, whatever I try, whatever paint settings I use
(dithering, antialias, etc..), the resized bitmaps are not
antialiased and the drawing present jagged edges. I tried everything.
The only little success I had was using inSampleSize
to approach the desired scaled size and force a first pass of
antialiasing, before invoking createScaledBitmap on the retrieved
hi-res bitmap, but it is not beautiful enough. I just can't allow to
create multitudes of pre-sized bitmaps for every combination
of resolution. What did I miss ?

Thanks a lot in advance
