Description

5 years ago
There is a LayoutInflater associated with every activity. This layout inflater is responsible for inflating views from XML. This is aware of "android.widget" namescape for creating Views. However, our custom views, like AboutHomeSection, take a round about way:
1. I tries to search if any factory can supply this.
2. It tried to find in default namespace.
3. It tries to resolve the view based on "package name" and "class name".

This can be avoided by asking it to search in the factory we supply to it. This will optimize the search done by android while inflating our custom views.

Patch

This patch uses a LayoutInflater.Factory. I felt it's better to use a singleton class that handles all the custom views, than every activity "implementing" LayoutInflater.Factory. 

This is the first attempt at it. Ideally, its better to hash all the view names in a HashMap for easier access.
