I'm afraid I don't understand the weight values. one of the points of a fixed height is that I'm drawing on the canvas for the view and it has to be as exact as i can get it so that i don't get empty space.
There is another view below it that will align to its bottom and should stretch to fill any left over space (via RelativeLayout). - Brill Pappin On Jan 24, 3:21 am, Dianne Hackborn <[email protected]> wrote: > Or you can put it in a LinearLayout and use android:layout_width="0px" > android:layout_weight="3" with another view in the container given > android:layout_weight="1". > > On Sun, Jan 23, 2011 at 11:37 PM, Kostya Vasilyev <[email protected]>wrote: > > > > > > > > > > > Brill, > > > Views specify their preferred size by overriding onMeasure. > > > You've got to deal with special values representing wrap_content and > > fill_parent (that's the MeasureSpec stuff): > > > Here is an example, it's a view that's placed inside a ScrollView and makes > > itself "tall", even in landscape orientation: > > > @Override > > protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { > > if (heightMeasureSpec != 0) { > > int sizeWidth = MeasureSpec.getSize(widthMeasureSpec); > > int sizeHeight = MeasureSpec.getSize(heightMeasureSpec); > > > if (sizeHeight < sizeWidth) { > > sizeHeight = sizeWidth * 3 / 2; > > > heightMeasureSpec = MeasureSpec.makeMeasureSpec(MeasureSpec > > .getMode(heightMeasureSpec), sizeHeight); > > } > > } > > > super.onMeasure(widthMeasureSpec, heightMeasureSpec); > > } > > > -- Kostya > > > 24.01.2011 7:45, Brill Pappin пишет: > > > Ok, I'm working on a custom view and having trouble with setting its size > > so it scales properly across devices. > > > In particular i want its fixed height to be relative to its width (of > > match_parent). > > > Something like this sudo code: > > > View myview = new View(..); > > > myview.setLayoutParams(new LayoutParams( > > > LayoutParams.MATCH_PARENT, ( MATCH_PARENT / 4) * 3)); > > > The goal would be to make the component height be 3/4's of the width. > > > This doesn't have to be done from outside. i.e. it could be done from > > inside the view, but I'm unsure what I need to override inside my > > view implementation to set the height.
