Instead, use the search widget as a collapsible view in the app bar. You can also enable "type-to-search" functionality, which activates the search dialog when the user starts typing on the keyboard—the keystrokes are inserted into the search dialog. The search dialog is a Dialog that floats at the top of the screen. It does not cause any change in the activity stack, so when the search dialog appears, no lifecycle methods such as onPause are called.
Your activity just loses input focus, as input focus is given to the search dialog. If you want to be notified when the search dialog is activated, override the onSearchRequested method.
When the system calls this method, it is an indication that your activity has lost input focus to the search dialog, so you can do any work appropriate for the event such as pause a game. Unless you are passing search context data discussed below , you should end the method by calling the super class implementation.
If the user cancels search by pressing the Back button, the search dialog closes and the activity regains input focus.
You should need to register only the OnDismissListener , because it is called every time the search dialog closes. The OnCancelListener only pertains to events in which the user explicitly exited the search dialog, so it is not called when a search is executed in which case, the search dialog naturally disappears.
If the current activity is not the searchable activity, then the normal activity lifecycle events are triggered once the user executes a search the current activity receives onPause and so forth, as described in the Activities document. If, however, the current activity is the searchable activity, then one of two things happens:.
Compared to the example code in the section about Performing a Search , all the code to handle the search intent is now in the handleIntent method, so that both onCreate and onNewIntent can execute it.
When the system calls onNewIntent Intent , the activity has not been restarted, so the getIntent method returns the same intent that was received with onCreate. This is why you should call setIntent Intent inside onNewIntent Intent so that the intent saved by the activity is updated in case you call getIntent in the future. The second scenario using "singleTop" launch mode is usually ideal, because chances are good that once a search is done, the user will perform additional searches and it's a bad experience if your application creates multiple instances of the searchable activity.
So, we recommend that you set your searchable activity to "singleTop" launch mode in the application manifest. In some cases, you can make necessary refinements to the search query inside the searchable activity, for every search made. However, if you want to refine your search criteria based on the activity from which the user is performing a search, you can provide additional data in the intent that the system sends to your searchable activity.
To pass this kind of data to your searchable activity, override the onSearchRequested method for the activity from which the user can perform a search, create a Bundle with the additional data, and call startSearch to activate the search dialog. Returning "true" indicates that you have successfully handled this callback event and called startSearch to activate the search dialog. Once the user submits a query, it's delivered to your searchable activity along with the data you've added.
Caution: Never call the startSearch method from outside the onSearchRequested callback method. To activate the search dialog in your activity, always call onSearchRequested. Otherwise, onSearchRequested is not called and customizations such as the addition of appData in the above example are missed.
Figure 2. The SearchView widget as an "action view" in the Action Bar. The SearchView widget is available in Android 3. If you're developing your application for Android 3. For example, figure 2 shows the search widget in the app bar. The search widget provides the same functionality as the search dialog. It starts the appropriate activity when the user executes a search, and it can provide search suggestions and perform voice search. If it's not an option for you to put the search widget in the Action Bar, you can instead put the search widget somewhere in your activity layout.
Note: When you use the search widget as an action view, you still might need to support using the search dialog, for cases in which the search widget does not fit in the Action Bar. See the following section about Using both the widget and the dialog.
After you've created a searchable configuration and a searchable activity , as discussed above, you need to enable assisted search for each SearchView. You can do so by calling setSearchableInfo and passing it the SearchableInfo object that represents your searchable configuration.
For example, if you're using a SearchView as an action view in the app bar , you should enable the widget during the onCreateOptionsMenu callback:. That's all you need. The search widget is now configured and the system will deliver search queries to your searchable activity. You can also enable search suggestions for the search widget. Note: If you want to handle all user input yourself, you can do so with some callback methods and event listeners. For more information, see the reference documentation for SearchView and its nested interfaces for the appropriate event listeners.
The SearchView widget allows for a few additional features you might want:. However, most of them are used only when you handle all user input yourself, instead of using the Android system to deliver search queries and display search suggestions.
For example, when your application runs on a smaller screen, there might not be enough room in the Action Bar to display the search widget along with other action items or navigation elements, so the menu item will instead appear in the overflow menu. When placed in the overflow menu, the item works like an ordinary menu item and does not display the action view the search widget.
To handle this situation, the menu item to which you've attached the search widget should activate the search dialog when the user selects it from the overflow menu.
In order for it to do so, you must implement onOptionsItemSelected to handle the "Search" menu item and open the search dialog by calling onSearchRequested.
For more information about how items in the Action Bar work and how to handle this situation, see the Action Bar developer guide. You can add voice search functionality to your search dialog or widget by adding the android:voiceSearchMode attribute to your searchable configuration. This adds a voice search button that launches a voice prompt. When the user has finished speaking, the transcribed search query is sent to your searchable activity.
The value showVoiceSearchButton is required to enable voice search, while the second value, launchRecognizer , specifies that the voice search button should launch a recognizer that returns the transcribed text to the searchable activity.
You can provide additional attributes to specify the voice search behavior, such as the language to be expected and the maximum number of results to return. See the Searchable Configuration reference for more information about the available attributes. Note: Carefully consider whether voice search is appropriate for your application. All searches performed with the voice search button are immediately sent to your searchable activity without a chance for the user to review the transcribed query.
Sufficiently test the voice recognition and ensure that it understands the types of queries that the user might submit inside your application. Figure 3. Screenshot of a search dialog with custom search suggestions.
Both the search dialog and the search widget can provide search suggestions as the user types, with assistance from the Android system. The system manages the list of suggestions and handles the event when the user selects a suggestion.
