Public methods
instantiate
public Fragment instantiate (ClassLoader classLoader,
String className)
Create a new instance of a Fragment with the given class name. This uses
loadFragmentClass(ClassLoader, String)
and the empty
constructor of the resulting Class by default.
Parameters |
classLoader |
ClassLoader : The default classloader to use for instantiation |
className |
String : The class name of the fragment to instantiate. |
Returns |
Fragment |
Returns a new fragment instance. |
Throws |
Fragment.InstantiationException |
If there is a failure in instantiating
the given fragment class. This is a runtime exception; it is not
normally expected to happen.
|
loadFragmentClass
public static Class<? extends Fragment> loadFragmentClass (ClassLoader classLoader,
String className)
Parse a Fragment Class from the given class name. The resulting Class is kept in a global
cache, bypassing the Class.forName(String)
calls when passed the same
class name again.
Parameters |
classLoader |
ClassLoader : The default classloader to use for loading the Class |
className |
String : The class name of the fragment to parse. |
Returns |
Class<? extends Fragment> |
Returns the parsed Fragment Class |
Throws |
Fragment.InstantiationException |
If there is a failure in parsing
the given fragment class. This is a runtime exception; it is not
normally expected to happen.
