• Method Detail

  • dispatchDraw

    protected void dispatchDraw(Canvas canvas)

    Description copied from class: ViewGroup
    Called by draw to draw the child views. This may be overridden by derived classes to gain control just before its children are drawn (but after its own view has been drawn).

    Overrides:

    dispatchDraw in class ListView

    Parameters:

    canvas - the canvas on which to draw the view

  • setChildDivider

    public void setChildDivider(Drawable childDivider)

    Sets the drawable that will be drawn adjacent to every child in the list. This will be drawn using the same height as the normal divider (ListView.setDivider(Drawable)) or if it does not have an intrinsic height, the height set by ListView.setDividerHeight(int).

    Parameters:

    childDivider - The drawable to use.

  • setAdapter

    public void setAdapter(ListAdapter adapter)

    This overloaded method should not be used, instead use setAdapter(ExpandableListAdapter).

    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 ListView

    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.

    See Also:

    ListView.getAdapter()

  • getAdapter

    This method should not be used, use getExpandableListAdapter().

    Overrides:

    getAdapter in class ListView

    Returns:

    The adapter currently used to display data in this ListView.

    See Also:

    ListView.setAdapter(ListAdapter)

  • setOnItemClickListener

    public void setOnItemClickListener(AdapterView.OnItemClickListener l)

    Register a callback to be invoked when an item has been clicked and the caller prefers to receive a ListView-style position instead of a group and/or child position. In most cases, the caller should use setOnGroupClickListener(android.widget.ExpandableListView.OnGroupClickListener) and/or setOnChildClickListener(android.widget.ExpandableListView.OnChildClickListener).

    Register a callback to be invoked when an item in this AdapterView has been clicked.

    Overrides:

    setOnItemClickListener in class AdapterView<ListAdapter>

    Parameters:

    l - The callback that will be invoked.

  • setAdapter

    public void setAdapter(ExpandableListAdapter adapter)

    Sets the adapter that provides data to this view.

    Parameters:

    adapter - The adapter that provides data to this view.

  • getExpandableListAdapter

                           int position,
                           long id)

    Description copied from class: AdapterView
    Call the OnItemClickListener, if it is defined.

    Overrides:

    performItemClick in class AbsListView

    Parameters:

    v - The view within the AdapterView that was clicked.

    position - The position of the view in the adapter.

    id - The row id of the item that was clicked.

    Returns:

    True if there was an assigned OnItemClickListener that was called, false otherwise is returned.

  • expandGroup

    public boolean expandGroup(int groupPos)

    Expand a group in the grouped list view

    Parameters:

    groupPos - the group to be expanded

    Returns:

    True if the group was expanded, false otherwise (if the group was already expanded, this will return false)

  • expandGroup

    public boolean expandGroup(int groupPos,
                      boolean animate)

    Expand a group in the grouped list view

    Parameters:

    groupPos - the group to be expanded

    animate - true if the expanding group should be animated in

    Returns:

    Collapse a group in the grouped list view

    Parameters:

    groupPos - position of the group to collapse

    Returns:

  • getExpandableListPosition

    public long getExpandableListPosition(int flatListPosition)

    Converts a flat list position (the raw position of an item (child or group) in the list) to a group and/or child position (represented in a packed position). This is useful in situations where the caller needs to use the underlying ListView's methods. Use getPackedPositionType(long) , getPackedPositionChild(long), getPackedPositionGroup(long) to unpack.

    Parameters:

    flatListPosition - The flat list position to be converted.

    Returns:

    The group and/or child position for the given flat list position in packed position representation. #PACKED_POSITION_VALUE_NULL if the position corresponds to a header or a footer item.

  • getFlatListPosition

    public int getFlatListPosition(long packedPosition)

    Converts a group and/or child position to a flat list position. This is useful in situations where the caller needs to use the underlying ListView's methods.

    Parameters:

    packedPosition - The group and/or child positions to be converted in packed position representation. Use getPackedPositionForChild(int, int) or getPackedPositionForGroup(int).

    Returns:

    The flat list position for the given child or group.

  • getSelectedPosition

    public long getSelectedPosition()

    Gets the position of the currently selected group or child (along with its type). Can return PACKED_POSITION_VALUE_NULL if no selection.

    Returns:

    A packed position containing the currently selected group or child's position and type. #PACKED_POSITION_VALUE_NULL if no selection or if selection is on a header or a footer item.

  • getSelectedId

    public long getSelectedId()

    Gets the ID of the currently selected group or child. Can return -1 if no selection.

    Returns:

    The ID of the currently selected group or child. -1 if no selection.

  • setSelectedGroup

    public void setSelectedGroup(int groupPosition)

    Sets the selection to the specified group.

    Parameters:

    groupPosition - The position of the group that should be selected.

  • setSelectedChild

    public boolean setSelectedChild(int groupPosition,
                           int childPosition,
                           boolean shouldExpandGroup)

    Sets the selection to the specified child. If the child is in a collapsed group, the group will only be expanded and child subsequently selected if shouldExpandGroup is set to true, otherwise the method will return false.

    Parameters:

    groupPosition - The position of the group that contains the child.

    childPosition - The position of the child within the group.

    shouldExpandGroup - Whether the child's group should be expanded if it is collapsed.

    Returns:

    Whether the selection was successfully set on the child.

  • isGroupExpanded

    public boolean isGroupExpanded(int groupPosition)

    Whether the given group is currently expanded.

    Parameters:

    groupPosition - The group to check.

    Returns:

    Whether the group is currently expanded.

  • getPackedPositionType

    public static int getPackedPositionType(long packedPosition)

    Gets the type of a packed position. See getPackedPositionForChild(int, int).

    Parameters:

    packedPosition - The packed position for which to return the type.

    Returns:

    The type of the position contained within the packed position, either PACKED_POSITION_TYPE_CHILD, PACKED_POSITION_TYPE_GROUP, or PACKED_POSITION_TYPE_NULL.

  • getPackedPositionGroup

    public static int getPackedPositionGroup(long packedPosition)

    Gets the group position from a packed position. See getPackedPositionForChild(int, int).

    Parameters:

    packedPosition - The packed position from which the group position will be returned.

    Returns:

    The group position portion of the packed position. If this does not contain a group, returns -1.

  • getPackedPositionChild

    public static int getPackedPositionChild(long packedPosition)

    Gets the child position from a packed position that is of PACKED_POSITION_TYPE_CHILD type (use getPackedPositionType(long)). To get the group that this child belongs to, use getPackedPositionGroup(long). See getPackedPositionForChild(int, int).

    Parameters:

    packedPosition - The packed position from which the child position will be returned.

    Returns:

    The child position portion of the packed position. If this does not contain a child, returns -1.

  • getPackedPositionForChild

    public static long getPackedPositionForChild(int groupPosition,
                                 int childPosition)

    Returns the packed position representation of a child's position.

    In general, a packed position should be used in situations where the position given to/returned from an ExpandableListAdapter or ExpandableListView method can either be a child or group. The two positions are packed into a single long which can be unpacked using getPackedPositionChild(long), getPackedPositionGroup(long), and getPackedPositionType(long).

    Parameters:

    groupPosition - The child's parent group's position.

    childPosition - The child position within the group.

    Returns:

    The packed position representation of the child (and parent group).

  • getPackedPositionForGroup

    public static long getPackedPositionForGroup(int groupPosition)

    Returns the packed position representation of a group's position. See getPackedPositionForChild(int, int).

    Parameters:

    groupPosition - The child's parent group's position.

    Returns:

    The packed position representation of the group.

  • setChildIndicator

    public void setChildIndicator(Drawable childIndicator)

    Sets the indicator to be drawn next to a child.

    Parameters:

    childIndicator - The drawable to be used as an indicator. If the child is the last child for a group, the state android.R.attr#state_last will be set.

  • setChildIndicatorBounds

    public void setChildIndicatorBounds(int left,
                               int right)

    Sets the drawing bounds for the child indicator. For either, you can specify CHILD_INDICATOR_INHERIT to use inherit from the general indicator's bounds.

    Parameters:

    left - The left position (relative to the left bounds of this View) to start drawing the indicator.

    right - The right position (relative to the left bounds of this View) to end the drawing of the indicator.

    See Also:

    setIndicatorBounds(int, int)

  • setGroupIndicator

    public void setGroupIndicator(Drawable groupIndicator)

    Sets the indicator to be drawn next to a group.

    Parameters:

    groupIndicator - The drawable to be used as an indicator. If the group is empty, the state android.R.attr#state_empty will be set. If the group is expanded, the state android.R.attr#state_expanded will be set.

  • setIndicatorBounds

    public void setIndicatorBounds(int left,
                          int right)

    Sets the drawing bounds for the indicators (at minimum, the group indicator is affected by this; the child indicator is affected by this if the child indicator bounds are set to inherit).

    Parameters:

    left - The left position (relative to the left bounds of this View) to start drawing the indicator.

    right - The right position (relative to the left bounds of this View) to end the drawing of the indicator.

  • onSaveInstanceState

    public Parcelable onSaveInstanceState()

    Description copied from class: View
    Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.

    Some examples of things you may store here: the current cursor position in a text view (but usually not the text itself since that is stored in a content provider or other persistent storage), the currently selected item in a list view.

    Overrides:

    onSaveInstanceState in class AbsListView

    Returns:

    Returns a Parcelable object containing the view's current dynamic state, or null if there is nothing interesting to save. The default implementation returns null.

    See Also:

    View.onRestoreInstanceState(android.os.Parcelable), View.saveHierarchyState(android.util.SparseArray), View.dispatchSaveInstanceState(android.util.SparseArray), View.setSaveEnabled(boolean)

  • onRestoreInstanceState

    public void onRestoreInstanceState(Parcelable state)

    Description copied from class: View
    Hook allowing a view to re-apply a representation of its internal state that had previously been generated by View.onSaveInstanceState(). This function will never be called with a null state.

    Overrides:

    onRestoreInstanceState in class AbsListView

    Parameters:

    state - The frozen state that had previously been returned by View.onSaveInstanceState().

    See Also:

    View.onSaveInstanceState(), View.restoreHierarchyState(android.util.SparseArray), View.dispatchRestoreInstanceState(android.util.SparseArray)

  • 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 ListView

    Parameters:

    event - The event to initialize.

    See Also:

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

  • onInitializeAccessibilityNodeInfo

    public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info)

    Description copied from class: View
    Initializes an AccessibilityNodeInfo with information about this view. The base implementation sets:

    • AccessibilityNodeInfo.setParent(View),
    • AccessibilityNodeInfo.setBoundsInParent(Rect),
    • AccessibilityNodeInfo.setBoundsInScreen(Rect),
    • AccessibilityNodeInfo.setPackageName(CharSequence),
    • AccessibilityNodeInfo.setClassName(CharSequence),
    • AccessibilityNodeInfo.setContentDescription(CharSequence),
    • AccessibilityNodeInfo.setEnabled(boolean),
    • AccessibilityNodeInfo.setClickable(boolean),
    • AccessibilityNodeInfo.setFocusable(boolean),
    • AccessibilityNodeInfo.setFocused(boolean),
    • AccessibilityNodeInfo.setLongClickable(boolean),
    • AccessibilityNodeInfo.setSelected(boolean),

    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 ListView

    Parameters:

    info - The instance to initialize.
