Method Details

create

public <F extends Fragment<?>> F create(FragmentOwner parent,
 Class<F> fragmentClass)

Description copied from interface: Fragments

Creates a fragment instance by its controller class.

For example:

    AddressFragment addressFragment = fragments.create(this, AddressFragment.class);
    getContent().add(addressFragment);
 

Specified by:

create in interface Fragments

Type Parameters:

F - fragment type

Parameters:

parent - parent UI controller

fragmentClass - fragment controller class

Returns:

fully initialized fragment instance

init

public void init(ComponentLoader.Context hostContext,
 Fragment<?> fragment)

Description copied from interface: Fragments

Initializes passed fragment by processing FragmentDescriptor.

Specified by:

init in interface Fragments

Parameters:

hostContext - parent controller loader context. Used to get additional data that is needed for correct initialization. For example, provided data components

fragment - fragment to initialize
