instantiate
@NonNull open fun instantiate(
@NonNull classLoader: ClassLoader,
@NonNull className: String
): Fragment
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. |
| Return |
Fragment |
Returns a new fragment instance. |
| Exceptions |
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
@NonNull open static fun loadFragmentClass(
@NonNull classLoader: ClassLoader,
@NonNull className: String
): Class<out Fragment!>
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. |
| Exceptions |
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. |
