|
| protected android.view.View | createView(int position, android.view.ViewGroup parent, int desiredHeight)Create a view for a list item. Override this to create a custom view beyond
the simple focusable / unfocusable text view.
return ListItemFactory.text(position, parent.getContext(), getValueAtPosition(position),
desiredHeight);
|
| public void | enableLongPress()Attaches a long press listener. You can find out which views were clicked by calling
{@link #getLongClickedPosition()}.

|
| protected abstract void | init(com.android.frameworktest.util.ListScenario$Params params)How each scenario customizes its behavior.
|
