Why does LayoutInflater ignore the layout_width and layout_height layout parameters I've specified?

Question

I\'ve had severe trouble getting LayoutInflater to work as expected, and so did other people: How to use layoutinflator to add views at runtime?.

Why does LayoutInfl

Answer 1

andig is correct that a common reason for LayoutInflater ignoring your layout_params would be because a root was not specified. Many people think you can pass in null for root. This is acceptable for a few scenarios such as a dialog, where you don't have access to root at the time of creation. A good rule to follow, however, is that if you have root, give it to LayoutInflater.
