Class Overview

A widget that provides a user interface for the user to enter a search query and submit a request to a search provider. Shows a list of query suggestions or results, if available, and allows the user to pick a suggestion or result to launch into.

When the SearchView is used in an ActionBar as an action view for a collapsible menu item, it needs to be set to iconified by default using setIconifiedByDefault(true). This is the default, so nothing needs to be done.

If you want the search field to always be visible, then call setIconifiedByDefault(false).

Developer Guides

For information about using SearchView, read the Search developer guide.

XML Attributes

android:iconifiedByDefault

The default state of the SearchView. If true, it will be iconified when not in use and expanded when clicked.

Must be a boolean value, either "true" or "false".

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol iconifiedByDefault.

android:imeOptions

The IME options to set on the query text field.

Must be one or more (separated by '|') of the following constant values.

ConstantValueDescription
normal0x00000000 There are no special semantics associated with this editor.
actionUnspecified0x00000000 There is no specific action associated with this editor, let the editor come up with its own if it can. Corresponds to IME_NULL.
actionNone0x00000001 This editor has no action associated with it. Corresponds to IME_ACTION_NONE.
actionGo0x00000002 The action key performs a "go" operation to take the user to the target of the text they typed. Typically used, for example, when entering a URL. Corresponds to IME_ACTION_GO.
actionSearch0x00000003 The action key performs a "search" operation, taking the user to the results of searching for the text the have typed (in whatever context is appropriate). Corresponds to IME_ACTION_SEARCH.
actionSend0x00000004 The action key performs a "send" operation, delivering the text to its target. This is typically used when composing a message. Corresponds to IME_ACTION_SEND.
actionNext0x00000005 The action key performs a "next" operation, taking the user to the next field that will accept text. Corresponds to IME_ACTION_NEXT.
actionDone0x00000006 The action key performs a "done" operation, closing the soft input method. Corresponds to IME_ACTION_DONE.
actionPrevious0x00000007 The action key performs a "previous" operation, taking the user to the previous field that will accept text. Corresponds to IME_ACTION_PREVIOUS.
flagNoFullscreen0x2000000 Used to request that the IME never go into fullscreen mode. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it.

Corresponds to IME_FLAG_NO_FULLSCREEN.

flagNavigatePrevious0x4000000 Like flagNavigateNext, but specifies there is something interesting that a backward navigation can focus on. If the user selects the IME's facility to backward navigate, this will show up in the application as an actionPrevious at InputConnection.performEditorAction(int).

Corresponds to IME_FLAG_NO_FULLSCREEN.

flagNavigateNext0x8000000 Used to specify that there is something interesting that a forward navigation can focus on. This is like using actionNext, except allows the IME to be multiline (with an enter key) as well as provide forward navigation. Note that some IMEs may not be able to do this, especially when running on a small screen where there is little space. In that case it does not need to present a UI for this option. Like actionNext, if the user selects the IME's facility to forward navigate, this will show up in the application at InputConnection.performEditorAction(int).

Corresponds to IME_FLAG_NAVIGATE_NEXT.

flagNoExtractUi0x10000000 Used to specify that the IME does not need to show its extracted text UI. For input methods that may be fullscreen, often when in landscape mode, this allows them to be smaller and let part of the application be shown behind. Though there will likely be limited access to the application available from the user, it can make the experience of a (mostly) fullscreen IME less jarring. Note that when this flag is specified the IME may not be set up to be able to display text, so it should only be used in situations where this is not needed.

Corresponds to IME_FLAG_NO_EXTRACT_UI.

flagNoAccessoryAction0x20000000 Used in conjunction with a custom action, this indicates that the action should not be available as an accessory button when the input method is full-screen. Note that by setting this flag, there can be cases where the action is simply never available to the user. Setting this generally means that you think showing text being edited is more important than the action you have supplied.

Corresponds to IME_FLAG_NO_ACCESSORY_ACTION.

flagNoEnterAction0x40000000 Used in conjunction with a custom action, this indicates that the action should not be available in-line as a replacement for the "enter" key. Typically this is because the action has such a significant impact or is not recoverable enough that accidentally hitting it should be avoided, such as sending a message. Note that TextView will automatically set this flag for you on multi-line text views.

Corresponds to IME_FLAG_NO_ENTER_ACTION.

flagForceAscii0x80000000 Used to request that the IME should be capable of inputting ASCII characters. The intention of this flag is to ensure that the user can type Roman alphabet characters in a TextView used for, typically, account ID or password input. It is expected that IMEs normally are able to input ASCII even without being told so (such IMEs already respect this flag in a sense), but there could be some cases they aren't when, for instance, only non-ASCII input languagaes like Arabic, Greek, Hebrew, Russian are enabled in the IME. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it. However, it is strongly recommended for IME authors to respect this flag especially when their IME could end up with a state that has only non-ASCII input languages enabled.

Corresponds to IME_FLAG_FORCE_ASCII.

This corresponds to the global attribute resource symbol imeOptions.

Added in API level 14

Called when this view is collapsed as an action view. See collapseActionView().

public void onActionViewExpanded ()

Added in API level 14

Called when this view is expanded as an action view. See expandActionView().

public void onInitializeAccessibilityEvent (AccessibilityEvent event)

Added in API level 14

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 setAccessibilityDelegate(AccessibilityDelegate) its 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.

Parameters
event The event to initialize.

public void onInitializeAccessibilityNodeInfo (AccessibilityNodeInfo info)

Added in API level 14

public void onWindowFocusChanged (boolean hasWindowFocus)

Added in API level 11

Called when the window containing this view gains or loses focus. Note that this is separate from view focus: to receive key events, both your view and its window must have focus. If a window is displayed on top of yours that takes input focus, then your own window will lose focus but the view focus will remain unchanged.

Parameters
hasWindowFocus True if the window containing this view now has focus, false otherwise.

public void setIconified (boolean iconify)

Added in API level 11

Iconifies or expands the SearchView. Any query text is cleared when iconified. This is a temporary state and does not override the default iconified state set by setIconifiedByDefault(boolean). If the default state is iconified, then a false here will only be valid until the user closes the field. And if the default state is expanded, then a true here will only clear the text field and not close it.

Parameters
iconify a true value will collapse the SearchView to an icon, while a false will expand it.

public void setIconifiedByDefault (boolean iconified)

Added in API level 11

Sets the default or resting state of the search field. If true, a single search icon is shown by default and expands to show the text field and other buttons when pressed. Also, if the default state is iconified, then it collapses to that state when the close button is pressed. Changes to this property will take effect immediately.

The default value is true.

public void setSearchableInfo (SearchableInfo searchable)

Added in API level 11

Sets the SearchableInfo for this SearchView. Properties in the SearchableInfo are used to display labels, hints, suggestions, create intents for launching search results screens and controlling other affordances such as a voice button.

Parameters
searchable a SearchableInfo can be retrieved from the SearchManager, for a specific activity or a global search provider.

Parameters
enabled true to show a submit button for submitting queries, false if a submit button is not required.

public void setSuggestionsAdapter (CursorAdapter adapter)

Added in API level 11

You can set a custom adapter if you wish. Otherwise the default adapter is used to display the suggestions from the suggestions provider associated with the SearchableInfo.

Protected Methods

protected void onDetachedFromWindow ()

Added in API level 11

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.

protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)

Added in API level 11

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.
