non constant values

[ankhers]

Forgive me if I skipped over the answer in a wiki entry, but how can I set a width or height value to something like 50pt?

I can't seem to find anything to deal with a height/width value that isn't :fill_parent, :wrap_content, though I have found that a regular integer is allowed. Nothing about other types of measurements (dp, sp, etc).

Thanks in advanced!

You can definitely put an integer value in the height/width fields (e.g.,
:layout => {:height= => 15}).

This sets the height field of:

http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html

That documentation does not specify unit of the integer at that moment. I'm
also not sure if there are any methods provided for easy conversion or if
you just have to do it yourself.

If you investigate this and get an answer, please post the result.

Apparently you need to convert to pixels, here is what I came up with,

java_import 'android.util.TypedValue'

px = TypedValue.applyDimension TypedValue::COMPLEX_UNIT_PT, 50, getResources.getDisplayMetrics

This will get me the 50pt value in pixels that I asked for in my original question, you can then set your height/width normally

image_view :image_resource => $package::R.drawable.logo, :height => px

the various values in place of COMPLEX_UNIT_PT can be found here: http://developer.android.com/reference/android/util/TypedValue.html

I will see if I can make this a little easier, and send in a pull request.

@woodjk , please also consider updating the wiki with your findings.
