Methods

newInstance

public static ListNetworksFragment newInstance(long selUser)

Returns a new instance of this fragment for the given section number.

onCreateView

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)

Setup the user interface to display the list of networks and populate that list with the result of calling API.Get.userNetworks(RequestQueue,long,Response.Listener).

Parameters:

• inflater – Inflates the user interface specified in R.layout.rv_container
• container – Parent of the generated hierarchy of user interface elements
• savedInstanceState – Saved state to restore

Returns:

Inflated user interface

onItemClick

public void onItemClick(View v, Network network)

This is the onClick() passed to NetworkSummaryAdapter. Thus, this is executed when the user taps on of the network card views. We want to view the tapped network in TimelineActivity.

Parameters:

• v – the CardView.
• network – The Network

onStop

public void onStop()

This ensures that we are canceling all network requests if the user is leaving this activity. We use a RequestFilter that accepts all requests (meaning it cancels all requests)
