LayoutInflater 详解

LayoutInflater 类用于初始化一个layout XML file into its corresponding View objects，他不能被直接实例化，只能通过getLayoutInflater()和getSystemService(String)两个方法实例一个标准的instance that is already hooked up to the current context and correctly configured for the device you are running on，

比如

LayoutInflater inflater = (LayoutInflater)context.getSystemService       Context.LAYOUT_INFLATER_SERVICE);

To create a new LayoutInflater with an additional LayoutInflater.Factory for your own views, 

you can use cloneInContext(Context) to clone an existing ViewFactory, 

and then call setFactory(LayoutInflater.Factory) on it to include your Factory.
