Public Methods

public void addFooterView (View v)

Since: API Level 1

Add a fixed view to appear at the bottom of the list. If addFooterView 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.

public void addFooterView (View v, Object data, boolean isSelectable)

Since: API Level 1

Add a fixed view to appear at the bottom of the list. If addFooterView 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	true if the footer view can be selected

public void addHeaderView (View v, Object data, boolean isSelectable)

Since: API Level 1

public void onRestoreInstanceState (Parcelable state)

Since: API Level 1

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

Parameters

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

public Parcelable onSaveInstanceState ()

Since: API Level 1

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.

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.

public boolean onTouchEvent (MotionEvent ev)

Implement this method to handle touch screen motion events.

Parameters

ev	The motion event.

Returns

True if the event was handled, false otherwise.

public boolean performItemClick (View view, int position, long id)

Parameters

view	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.

public boolean removeFooterView (View v)

Returns

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

public boolean requestChildRectangleOnScreen (View child, Rect rect, boolean immediate)

Since: API Level 1

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

Parameters

child	The direct child making the request.
rect	The rectangle in the child's coordinates the child wishes to be on the screen.
immediate	True to forbid animated or delayed scrolling, false otherwise

Returns

Whether the group scrolled to handle the operation

public void setAdapter (ListAdapter adapter)

Since: API Level 1

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.

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.

public void setCacheColorHint (int color)

Since: API Level 1

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

Parameters

color	The background color

public void setChoiceMode (int choiceMode)

Since: API Level 1

Defines the choice behavior for the List. By default, Lists do not have any choice behavior (CHOICE_MODE_NONE).

By setting the choiceMode to CHOICE_MODE_MULTIPLE, the list allows any number of items to be chosen.

Parameters

choiceMode	One of `CHOICE_MODE_NONE`, `CHOICE_MODE_SINGLE`, or `CHOICE_MODE_MULTIPLE`

public void setDivider (Drawable divider)

Since: API Level 1

Sets the drawable that will be drawn between each item in the list. If the drawable does not have an intrinsic height, you should also call setDividerHeight(int)

Parameters

divider	The drawable to use.

public void setDividerHeight (int height)

Since: API Level 1

Sets the height of the divider that will be drawn between each item in the list. Calling this will override the intrinsic height as set by setDivider(Drawable)

public void setFooterDividersEnabled (boolean footerDividersEnabled)

Since: API Level 3

Enables or disables the drawing of the divider for footer views.

Parameters

public void setOverscrollHeader (Drawable header)

Since: API Level 9

Sets the drawable that will be drawn above all other list content. This area can become visible when the user overscrolls the list.

Parameters

header	The drawable to use

public void setSelection (int position)

Since: API Level 1

Sets the currently selected item. If in touch mode, the item will not be selected but it will still be positioned appropriately. If the specified selection position is less than 0, then the item at position 0 will be selected.

Parameters

position	Index (starting at 0) of the data item to be selected.

public void setSelectionAfterHeaderView ()

Since: API Level 1

setSelectionAfterHeaderView set the selection to be the first list item after the header views.

public void setSelectionFromTop (int position, int y)

position	Index (starting at 0) of the data item to be selected.
y	The distance from the top edge of the ListView (plus padding) that the item will be positioned.

Protected Methods

protected boolean canAnimate ()

Since: API Level 1

Indicates whether the view group has the ability to animate its children after the first layout.

Returns

true if the children can be animated, false otherwise

protected void dispatchDraw (Canvas canvas)

Since: API Level 1

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).

Parameters

canvas	the canvas on which to draw the view

protected View findViewTraversal (int id)

Since: API Level 1

Parameters

id	the id of the view to be found

Returns

the view of the specified id, null if cannot be found

protected View findViewWithTagTraversal (Object tag)

Since: API Level 1

Parameters

tag	the tag of the view to be found

Returns

the view of specified tag, null if cannot be found

protected void layoutChildren ()

Since: API Level 1

Subclasses must override this method to layout their children.

protected void onFinishInflate ()

Since: API Level 1

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

Even if the subclass overrides onFinishInflate, they should always be sure to call the super method, so that we get called.

protected void onFocusChanged (boolean gainFocus, int direction, Rect previouslyFocusedRect)

Since: API Level 1

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.

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 `FOCUS_UP`, `FOCUS_DOWN`, `FOCUS_LEFT` or `FOCUS_RIGHT`. 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.

protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)

Since: API Level 1

Measure the view and its content to determine the measured width and the measured height. This method is invoked by 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 setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by measure(int, int). Calling the superclass' 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 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 (getSuggestedMinimumHeight() and getSuggestedMinimumWidth()).

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`.

protected void onSizeChanged (int w, int h, int oldw, int oldh)

Since: API Level 1

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.

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.
