SearchView

public class SearchView
extends LinearLayoutCompat implements CollapsibleActionView

java.lang.Object
   ↳ android.view.View
     ↳ android.view.ViewGroup
       ↳ android.support.v7.widget.LinearLayoutCompat
         ↳ android.support.v7.widget.SearchView


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.

Note: This class is included in the support library for compatibility with API level 7 and higher. If you're developing your app for API level 11 and higher only, you should instead use the framework SearchView class.

When the SearchView is used in an ActionBar as an action view, it's collapsed by default, so you must provide an icon for the action.

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

Developer Guides

For information about using SearchView, read the Search API guide. Additional information about action views is also available in the <Action Bar API guide

Returns
boolean

isIconified

boolean isIconified ()

Returns the current iconified state of the SearchView.

Returns
boolean true if the SearchView is currently iconified, false if the search field is fully visible.

isQueryRefinementEnabled

boolean isQueryRefinementEnabled ()

Returns whether query refinement is enabled for all items or only specific ones.

Returns
boolean true if enabled for all items, false otherwise.

isSubmitButtonEnabled

boolean isSubmitButtonEnabled ()

onActionViewCollapsed

void onActionViewCollapsed ()

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

onActionViewExpanded

void onActionViewExpanded ()

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

onWindowFocusChanged

void onWindowFocusChanged (boolean hasWindowFocus)

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 boolean: True if the window containing this view now has focus, false otherwise.

setIconified

void setIconified (boolean iconify)

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

setIconifiedByDefault

void setIconifiedByDefault (boolean iconified)

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.

                boolean submit)

Sets a query string in the text field and optionally submits the query as well.

Parameters
query CharSequence: the query string. This replaces any query text already present in the text field.
submit boolean: whether to submit the query right now or only update the contents of text field.

setQueryHint

void setQueryHint (CharSequence hint)

Sets the hint text to display in the query text field. This overrides any hint specified in the SearchableInfo.

This value may be specified as an empty string to prevent any query hint from being displayed.

Related XML Attributes:

Parameters
hint CharSequence: the hint text to display or null to clear

setQueryRefinementEnabled

void setQueryRefinementEnabled (boolean enable)

Specifies if a query refinement button should be displayed alongside each suggestion or if it should depend on the flags set in the individual items retrieved from the suggestions provider. Clicking on the query refinement button will replace the text in the query text field with the text from the suggestion. This flag only takes effect if a SearchableInfo has been specified with setSearchableInfo(SearchableInfo) and not when using a custom adapter.

Parameters
enable boolean: true if all items should have a query refinement button, false if only those items that have a query refinement flag set should have the button.

See also:

setSearchableInfo

void setSearchableInfo (SearchableInfo searchable)

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

setSubmitButtonEnabled

void setSubmitButtonEnabled (boolean enabled)

Enables showing a submit button when the query is non-empty. In cases where the SearchView is being used to filter the contents of the current activity and doesn't launch a separate results activity, then the submit button should be disabled.

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

setSuggestionsAdapter

void setSuggestionsAdapter (CursorAdapter adapter)

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.

Parameters
adapter CursorAdapter

Protected methods

onDetachedFromWindow

void onDetachedFromWindow ()

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

onLayout

void onLayout (boolean changed, 
                int left, 
                int top, 
                int right, 
                int bottom)

Called from layout when this view should assign a size and position to each of its children. Derived classes with children should override this method and call layout on each of their children.

Parameters
changed boolean: This is a new size or position for this view
left int: Left position, relative to parent
top int: Top position, relative to parent
right int: Right position, relative to parent
bottom int: Bottom position, relative to parent

onMeasure

void onMeasure (int widthMeasureSpec, 
                int heightMeasureSpec)

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 overridden 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 int: horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
heightMeasureSpec int: vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

onRestoreInstanceState

void onRestoreInstanceState (Parcelable state)

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

onSaveInstanceState

Parcelable onSaveInstanceState ()

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
Parcelable 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.
