Android SearchView Widget with ActionBarCompat library

August 6, 2013
By

In this article we will develop an Android application that demonstrates how to create a searchview widget in action bar using ActionBarCompat library.

This application facilitates users to search places using Google Places API. As user types in place name in searchview, places that matches the typed in characters will be listed as suggestions. On selecting an item from the suggestion, the corresponding place will be shown in the Google Maps Android API V2.

We need following for this application :

ActionBarCompat library : We know that, SearchView widget is only available since Android API Level 11 and its previous versions does not have the SearchView widget. In order for the backward compatibility, we can use ActionBarCompat library which is available with Android Support library revision 18.

Google Play Services Library : Since we are using Google Maps Android API V2 with this application, we need Google Play Service library for this application to work.

Configuration file for SearchView widget : This configuration file is used to configure the searchview widget. For this application, this file is available at res/xml/searchable.xml

Searchable Activity : An activity that handles the search requests from searchview widget. In this application, MainActivity acts as the searchable activity.

Content Provider : The searchview widget performs the search operation on the data provided by the content provider.

Loaders : Loaders are used to execute tasks in background ( non-ui thread ) . We are using two loaders in the MainActivity class. One loader is used in the method doSearch() which is invoked when user presses the “Go” button of the soft keyboard. The second loader is used in the method “getPlace()”, which is invoked when an item in the search suggestion list is selected.

Activity Style : The activity that implements the action bar should apply the style Theme.AppCompat or Theme.AppCompat.Light  or Theme.AppCompat.DarkActionBar.  This can be done in AndroidManifest.xml file.

This application is developed in Eclipse 4.2.0 with ADT plugin 22.0.5, Android Support library 18 and Google Play Service library 9.

 6. Setup ActionBarCompat library in Eclipse IDE

Please refer the article titled “Android – Setting up ActionBarCompat support library in Eclipse


7. Download and configure Google Play Services Library in Eclipse

Please follow the given below link to setup Google Play Service library in Eclipse.

http://developer.android.com/google/play-services/setup.html


8. Link this project to ActionBarCompat library and Google Play Service llibrary

9. Get the API key for Google Maps Android API V2

We need to get an API key from Google to use Google Maps in Android application.

Please follow the given below link to get the API key for Google Maps Android API v2.

https://developers.google.com/maps/documentation/android/start


10. Get the API key for Google Places API

We can create API key for Google Place API by clicking “Create new Browser key”  available at the “API Access” pane of the Google console URL : http://code.google.com/apis/console.

Also ensure that, “Places API” is enabled in the “Services” pane of the Google console.


11. Update the file res/values/strings.xml


<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">SearchViewWithActionBarCompat</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Hello world!</string>
    <string name="action_search">Search</string>
    <string name="search_hint">Search Places</string>
    <string name="search_settings">Search Places</string>

</resources>


12. Update the layout file res/layout/activity_main.xml


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <fragment
        android:id="@+id/map"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>


13. Update the menu file res/menu/main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:myapp="http://schemas.android.com/apk/res-auto" >

    <item
        android:id="@+id/action_search"
        android:orderInCategory="100"
        android:title="@string/action_search"
        myapp:actionViewClass="android.support.v7.widget.SearchView"
        myapp:showAsAction="always" />

    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="@string/action_settings"/>

    Good tutorial, but sorry it doesn’t work for me.

  2. lucas on November 1, 2013 at 9:36 pm

    Great tutorial

    I was trying to do something like this, but I didn’t understand how your main activity could call the method .getCountries(selectionArgs) on CountryContentProvider.

    when I press the button search country the method getCountries is called

    how does it works?

    sorry about the bad english

  3. Luis Miguel on August 21, 2014 at 9:02 pm

    Good tutorial, but sorry it doesn’t work for me.

    I have this problem:
    Could not find class ‘android.support.v7.widget.SearchView$5′, referenced from method android.support.v7.widget.SearchView.addOnLayoutChangeListenerToDropDownAnchorSDK11

    Have you had this problem?
    I am not sure if this bug Is actually causing any problems.

    Thanks

    Hi great tutorial, thanks so much. I was struggling with the SearchView Widget for a long time.

    The error is:
    Could not find class ‘android.support.v7.widget.SearchView$5′

    I think that is a component bug. Have you ever had this problem?

    Thanks!
