                     boolean isSelectable)

    Add a fixed view to appear at the top of the list. If addHeaderView is called more than once, the views will appear in the order they were added. Views added using this call can take focus if they want.

    NOTE: Call this before calling setAdapter. This is so ListView can wrap the supplied cursor with one that will also account for header and footer views.

    Parameters:

    v - The view to add.

    data - Data to associate with this view

    isSelectable - whether the item is selectable

  • addHeaderView

    public void addHeaderView(View v)

    true if the view was removed, false if the view was not a footer view

  • getAdapter

    public ListAdapter getAdapter()

    Returns the adapter currently in use in this ListView. The returned adapter might not be the same adapter passed to setAdapter(ListAdapter) but might be a WrapperListAdapter.

    Specified by:

    getAdapter in class AdapterView<ListAdapter>

    Returns:

    The adapter currently used to display data in this ListView.

    See Also:

    setAdapter(ListAdapter)

    Parameters:

    intent - the intent used to identify the RemoteViewsService for the adapter to connect to.

  • setAdapter

    public void setAdapter(ListAdapter adapter)

    Sets the data behind this ListView. The adapter passed to this method may be wrapped by a WrapperListAdapter, depending on the ListView features currently in use. For instance, adding headers and/or footers will cause the adapter to be wrapped.

    Overrides:

    setAdapter in class AbsListView

    Parameters:

    adapter - The ListAdapter which is responsible for maintaining the data backing this list and for producing a view to represent an item in that data set.

                                        boolean immediate)

    Description copied from class: ViewGroup
    Called when a child of this group wants a particular rectangle to be positioned onto the screen. ViewGroups overriding this can trust that:

    • child will be a direct child of this group
    • rectangle will be in the child's coordinates

    ViewGroups overriding this should uphold the contract:

    • nothing will change if the rectangle is already visible
    • the view port will be scrolled only just enough to make the rectangle visible

    Specified by:

    requestChildRectangleOnScreen in interface ViewParent

    Overrides:

    requestChildRectangleOnScreen in class ViewGroup

    Parameters:

                     int oldw,
                     int oldh)

    Description copied from class: View
    This is called during layout when the size of this view has changed. If you were just added to the view hierarchy, you're called with the old values of 0.

    Overrides:

    onSizeChanged in class AbsListView

    Parameters:

    w - Current width of this view.

    h - Current height of this view.

    oldw - Old width of this view.

    oldh - Old height of this view.

  • onMeasure

    protected void onMeasure(int widthMeasureSpec,
                 int heightMeasureSpec)

    Description copied from class: View

    Measure the view and its content to determine the measured width and the measured height. This method is invoked by View.measure(int, int) and should be overriden by subclasses to provide accurate and efficient measurement of their contents.

    CONTRACT: When overriding this method, you must call View.setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by View.measure(int, int). Calling the superclass' View.onMeasure(int, int) is a valid use.

    The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override View.onMeasure(int, int) to provide better measurements of their content.

    If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (View.getSuggestedMinimumHeight() and View.getSuggestedMinimumWidth()).

    Overrides:

    onMeasure in class AbsListView

    Parameters:

    widthMeasureSpec - horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

    heightMeasureSpec - vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

    See Also:

    View.getMeasuredWidth(), View.getMeasuredHeight(), View.setMeasuredDimension(int, int), View.getSuggestedMinimumHeight(), View.getSuggestedMinimumWidth(), View.MeasureSpec.getMode(int), View.MeasureSpec.getSize(int)

    Specified by:

    onKeyDown in interface KeyEvent.Callback

    Overrides:

    onKeyDown in class AbsListView

    Parameters:

    keyCode - A key code that represents the button pressed, from KeyEvent.

                        KeyEvent event)

    Description copied from class: View
    Default implementation of KeyEvent.Callback.onKeyMultiple(): always returns false (doesn't handle the event).

    Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

    Specified by:

    onKeyMultiple in interface KeyEvent.Callback

    Overrides:

    onKeyMultiple in class View

    Parameters:

    keyCode - A key code that represents the button pressed, from KeyEvent.

                  KeyEvent event)

    Description copied from class: View
    Default implementation of KeyEvent.Callback.onKeyUp(): perform clicking of the view when KeyEvent.KEYCODE_DPAD_CENTER or KeyEvent.KEYCODE_ENTER is released.

    Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

    Specified by:

    onKeyUp in interface KeyEvent.Callback

    Overrides:

    onKeyUp in class AbsListView

    Parameters:

    keyCode - A key code that represents the button pressed, from KeyEvent.

    Returns:

    Whether the views created by the ListAdapter can contain focusable items.

  • isOpaque

    public boolean isOpaque()

    Description copied from class: View
    Indicates whether this View is opaque. An opaque View guarantees that it will draw all the pixels overlapping its bounds using a fully opaque color. Subclasses of View should override this method whenever possible to indicate whether an instance is opaque. Opaque Views are treated in a special way by the View hierarchy, possibly allowing it to perform optimizations during invalidate/draw passes.

    Overrides:

    isOpaque in class View

    Returns:

    True if this View is guaranteed to be fully opaque, false otherwise.

  • setCacheColorHint

    public void setCacheColorHint(int color)

    Description copied from class: AbsListView
    When set to a non-zero value, the cache color hint indicates that this list is always drawn on top of a solid, single-color, opaque background. Zero means that what's behind this object is translucent (non solid) or is not made of a single color. This hint will not affect any existing background drawable set on this view ( typically set via View.setBackgroundDrawable(Drawable)).

    Overrides:

    setCacheColorHint in class AbsListView

    Parameters:

    color - The background color

  • dispatchDraw

    protected void dispatchDraw(Canvas canvas)

    Description copied from class: ViewGroup

    Overrides:

    drawChild in class ViewGroup

    Parameters:

    canvas - The canvas on which to draw the child

    child - Who to draw

    drawingTime - The time at which draw is occurring

                      Rect previouslyFocusedRect)

    Description copied from class: View
    Called by the view system when the focus state of this view changes. When the focus change event is caused by directional navigation, direction and previouslyFocusedRect provide insight into where the focus is coming from. When overriding, be sure to call up through to the super class so that the standard focus handling will occur.

    Overrides:

    onFocusChanged in class AbsListView

    Parameters:

    gainFocus - True if the View has focus; false otherwise.

    direction - The direction focus has moved when requestFocus() is called to give this view focus. Values are View.FOCUS_UP, View.FOCUS_DOWN, View.FOCUS_LEFT, View.FOCUS_RIGHT, View.FOCUS_FORWARD, or View.FOCUS_BACKWARD. It may not always apply, in which case use the default.

    previouslyFocusedRect - The rectangle, in this view's coordinate system, of the previously focused view. If applicable, this will be passed in as finer grained information about where the focus is coming from (in addition to direction). Will be null otherwise.

  • onFinishInflate

    protected void onFinishInflate()

    Description copied from class: View
    Finalize inflating a view from XML. This is called as the last phase of inflation, after all child views have been added.

  • onInitializeAccessibilityEvent

    public void onInitializeAccessibilityEvent(AccessibilityEvent event)

    Description copied from class: View
    Initializes an AccessibilityEvent with information about this View which is the event source. In other words, the source of an accessibility event is the view whose state change triggered firing the event.

    Example: Setting the password property of an event in addition to properties set by the super implementation:

     public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
         super.onInitializeAccessibilityEvent(event);
         event.setPassword(true);
     }

    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.

    Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add.

    Overrides:

    onInitializeAccessibilityEvent in class AbsListView

    Parameters:

    event - The event to initialize.

    See Also:

    View.sendAccessibilityEvent(int), View.dispatchPopulateAccessibilityEvent(AccessibilityEvent)

  • onInitializeAccessibilityNodeInfo

    public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info)

    Subclasses should override this method, call the super implementation, and set additional attributes.

    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo) is responsible for handling this call.

    Overrides:

    onInitializeAccessibilityNodeInfo in class AbsListView

    Parameters:

    info - The instance to initialize.
