ListFragment

public class ListFragment
extends Fragment

java.lang.Object
   ↳ android.support.v4.app.Fragment
     ↳ android.support.v4.app.ListFragment


Static library support version of the framework's ListFragment. Used to write apps that run on platforms prior to Android 3.0. When running on Android 3.0 or above, this implementation is still used; it does not try to switch to the framework's implementation. See the framework SDK documentation for a class overview.

onCreateView

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

Provide default implementation to return a simple list view. Subclasses can override to replace with their own layout. If doing so, the returned view hierarchy must have a ListView whose id is android.R.id.list and can optionally have a sibling view id android.R.id.empty that is to be shown when the list is empty.

If you are overriding this method with your own custom content, consider including the standard layout list_content in your layout file, so that you continue to retain all of the standard behavior of ListFragment. In particular, this is currently the only way to have the built-in indeterminant progress state be shown.

Parameters
inflater LayoutInflater: The LayoutInflater object that can be used to inflate any views in the fragment,
container ViewGroup: If non-null, this is the parent view that the fragment's UI should be attached to. The fragment should not add the view itself, but this can be used to generate the LayoutParams of the view.
savedInstanceState Bundle: If non-null, this fragment is being re-constructed from a previous saved state as given here.
Returns
View Return the View for the fragment's UI, or null.

onDestroyView

void onDestroyView ()

Detach from list view.

onListItemClick

void onListItemClick (ListView l, 
                View v, 
                int position, 
                long id)

This method will be called when an item in the list is selected. Subclasses should override. Subclasses can call getListView().getItemAtPosition(position) if they need to access the data associated with the selected item.

Parameters
l ListView: The ListView where the click happened
v View: The view that was clicked within the ListView
position int: The position of the view in the list
id long: The row id of the item that was clicked

onViewCreated

void onViewCreated (View view, 
                Bundle savedInstanceState)

Attach to list view once the view hierarchy has been created.

Parameters
view View: The View returned by onCreateView(LayoutInflater, ViewGroup, Bundle).
savedInstanceState Bundle: If non-null, this fragment is being re-constructed from a previous saved state as given here.

setEmptyText

void setEmptyText (CharSequence text)

The default content for a ListFragment has a TextView that can be shown when the list is empty. If you would like to have it shown, call this method to supply the text it should use.

Parameters
text CharSequence

setListAdapter

void setListAdapter (ListAdapter adapter)

Provide the cursor for the list view.

Parameters
adapter ListAdapter

setListShown

void setListShown (boolean shown)

Control whether the list is being displayed. You can make it not displayed if you are waiting for the initial data to show in it. During this time an indeterminant progress indicator will be shown instead.

Applications do not normally need to use this themselves. The default behavior of ListFragment is to start with the list not being shown, only showing it once an adapter is given with setListAdapter(ListAdapter). If the list at that point had not been shown, when it does get shown it will be do without the user ever seeing the hidden state.

Parameters
shown boolean: If true, the list view is shown; if false, the progress indicator. The initial value is true.

setListShownNoAnimation

void setListShownNoAnimation (boolean shown)

Like setListShown(boolean), but no animation is used when transitioning from the previous state.

Parameters
shown boolean

setSelection

void setSelection (int position)

Set the currently selected list item to the specified position with the adapter's data
