I got following error when inflating this layout:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.trill.trillapp/com.trill.trillapp.activities.TrillDetailArticle}: 
java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x1

How to fix it?

回答1:

I've found that i lack of value in dimens.xml file. So it cause error

回答2:

As with all android resources, dimensions are stored in various qualified values.

values\dimens.xml
values-v21\dimens.xml
values-land\dimens.xml

It may be that the dimension is available in some, but not all necessary locations.

The easiest fix for this problem, is to add an entry into values\dimens.xml which is the fall-back place if any of the specifics fail.
