Class AbstractPaymentFragment

java.lang.Object

android.app.Fragment

com.wallee.android.sdk.fragment.AbstractPaymentFragment

All Implemented Interfaces:

android.content.ComponentCallbacks, android.content.ComponentCallbacks2, android.view.View.OnCreateContextMenuListener

Direct Known Subclasses:

ActivityAwarePaymentFragment

public abstract class AbstractPaymentFragment
extends android.app.Fragment

This is an abstract fragment which helps to use FlowCoordinator.

This abstract fragment allows to process a whole payment flow. It manages every step of the payment flow. Customization options:

• Inject a custom FragmentFlowListener which allows to modify the behaviour.
• Override the createFlowConfigurationBuilder(FlowListener) method to adjust the coordinator configuration to change the view etc.
• Override the layout files to adjust the look and feel of the views.
• Override the createPaymentContainerEnlarger(ViewGroup) method to inject a custom enlarger which provides more flexibility around how the form behaves within the activity.

Constructor Detail

AbstractPaymentFragment

public AbstractPaymentFragment()

Method Detail

onBackPressed

public boolean onBackPressed()

This method can be invoked to trigger going back within the payment fragment.

Returns:

true when the event was handled by the fragment.

getCredentialsProviderResolver

protected abstract CredentialsProviderResolver getCredentialsProviderResolver()

This method returns the resolver of CredentialsProvider. The implementor may create an instance of it or fetch it from some other source.

Returns:

the resolver of the CredentialsProvider.

getFragmentTerminationListener

protected abstract FragmentTerminationListener getFragmentTerminationListener()

This method returns the listener which reacts up on the final states of the payment process.

Returns:

the listener which reacts up on the finale states of the transaction.

onCreateView

public final android.view.View onCreateView(android.view.LayoutInflater inflater,
                                            android.view.ViewGroup container,
                                            android.os.Bundle savedInstanceState)

Overrides:

onCreateView in class android.app.Fragment

onSaveInstanceState

public void onSaveInstanceState(android.os.Bundle outState)

Overrides:

onSaveInstanceState in class android.app.Fragment

onDestroy

public void onDestroy()

Overrides:

onDestroy in class android.app.Fragment

createFlowConfigurationBuilder

protected FlowConfiguration.Builder createFlowConfigurationBuilder(FlowListener listener)

This method constructs the coordinator configuration. Subclasses may override this method to inject custom configuration values such as FlowListener. It allows also to provide custom view factories to inject custom views for the different views within the coordinator.

Parameters:

listener - the fragment listener. This listener is responsible to react based upon the events within the coordinator to adjust the fragment.

Returns:

the configuration builder which may be modified by the subclasses.

createEventListener

protected FragmentFlowListener createEventListener(PaymentContainerEnlarger enlarger,
                                                   FragmentTerminationListener fragmentTerminationListener,
                                                   android.view.ViewGroup fragmentView)

This method creates the fragment listener for the flow. Essentially this listener is responsible to map the flow events to the fragment functionality.

Parameters:

enlarger - the enlarge which is used. This is created through createPaymentContainerEnlarger(ViewGroup),

fragmentTerminationListener - the listener which coordinates the outcome of the payment process.

fragmentView - the fragment view holds all views for the fragment.

Returns:

the listener which realizes the communication between the fragment and the coordinator.

createPaymentContainerEnlarger

protected PaymentContainerEnlarger createPaymentContainerEnlarger(android.view.ViewGroup paymentFormContainer)

This method creates the view enlarger which is responsible to create more space for the payment form within the activity.

Parameters:

paymentFormContainer - the container within which the coordinator places it's views.

Returns:

the enlarger which is used to manage the resize of the fragment.
