[android-developers] obtaining true dimensions of a View larger than the screen
Hello, trying to implement a dynamic scrolview wrapping mechanism here. But no matter what method I try from the View class they all return me the view's part of height that is currently visible on screen. So if there are 360 pixels available for a textview that has lots of text and is currently using 400 pixels its getHeight() and many other related methods always report 360. Any way around this ? maybe getting to the View's Canvas ? How can I go about that ? Thank you! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: obtaining true dimensions of a View larger than the screen
Good hint. I was able to do
int h1 = computeVerticalScrollExtent();
int h3 = computeVerticalScrollRange();
if (h1 == h3)
{
//switch to linearlayout wrapper
}
inside a ScrollView wrapper. The above methods return the same thing
on a LinearLayout though (and probably also on regular Views), so at
first the trick needs assuming that the wrapped View needs a scrollbar
and then see if it really needs one.
Thanks!

Beyond that, you will need to look at a specific class that is doing
scrolling.

[android-developers] ListView Drawables
Hi,
Can anyone point me to the right way of drawing a circle as part of a
ListView row ? The code below used to work ok in some android beta SDK
but now under 1.6 it only draws me a black cirle. How can I change
it's colour from getView(..) ?
My code:
public View getView(int position, View convertView,
android.view.ViewGroup parent)
{
View singleView;
LinearLayout lL = new LinearLayout (getContext());
OvalShape circle = new OvalShape();
circle.resize(8, 8);
ShapeDrawable dwb = new ShapeDrawable (circle);
PointColour clr = ((ListRow) content[position]).pointColour;
dwb.setColorFilter(Color.argb (clr.getAlpha(), clr.getRed(),
clr.getGreen(), clr.getBlue() ), PorterDuff.Mode.SRC);
dwb.setIntrinsicWidth(10);
dwb.setIntrinsicHeight(10);
singleView = new ImageView (getContext());
((ImageView)singleView).setImageDrawable(dwb);
LayoutParams params = new LayoutParams (10, 10);
lL.addView(singleView, params);
singleView = new TextView (getContext());
((TextView)singleView).setText((CharSequence) ( +
((ListRow)content[position]).participant));
params = new LayoutParams (189, 20);
lL.addView(singleView, params);
return lL;
}
