To get Places Autocomplete API results in a SearchView, you'll first need a ContentProvider for the API.

import android.app.SearchManager;
import android.content.ContentProvider;
import android.content.ContentValues;
import android.content.UriMatcher;
import android.database.Cursor;
import android.database.MatrixCursor;
import android.net.Uri;
import android.provider.BaseColumns;
import android.util.Log;

public class PlacesSuggestionProvider extends ContentProvider {
    private static final String LOG_TAG = "ExampleApp";

    public static final String AUTHORITY = "com.example.google.places.search_suggestion_provider";
    public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/search");

    // UriMatcher constant for search suggestions
    private static final int SEARCH_SUGGEST = 1;

    private static final UriMatcher uriMatcher;

    private static final String[] SEARCH_SUGGEST_COLUMNS = {
            BaseColumns._ID,
            SearchManager.SUGGEST_COLUMN_TEXT_1,
            SearchManager.SUGGEST_COLUMN_TEXT_2,
            SearchManager.SUGGEST_COLUMN_INTENT_DATA_ID
    };

    static {
        uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
        uriMatcher.addURI(AUTHORITY, SearchManager.SUGGEST_URI_PATH_QUERY, SEARCH_SUGGEST);
        uriMatcher.addURI(AUTHORITY, SearchManager.SUGGEST_URI_PATH_QUERY + "/*", SEARCH_SUGGEST);
    }

    @Override
    public int delete(Uri uri, String arg1, String[] arg2) {
        throw new UnsupportedOperationException();
    }

    @Override
    public String getType(Uri uri) {
        switch (uriMatcher.match(uri)) {
            case SEARCH_SUGGEST:
                return SearchManager.SUGGEST_MIME_TYPE;
            default:
                throw new IllegalArgumentException("Unknown URL " + uri);
        }
    }

    @Override
    public Uri insert(Uri uri, ContentValues arg1) {
        throw new UnsupportedOperationException();
    }

    @Override
    public boolean onCreate() {
        return true;
    }

    @Override
    public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs,
            String sortOrder) {
        Log.d(LOG_TAG, "query = " + uri);

        // Use the UriMatcher to see what kind of query we have
        switch (uriMatcher.match(uri)) {
            case SEARCH_SUGGEST:
                Log.d(LOG_TAG, "Search suggestions requested.");
                MatrixCursor cursor = new MatrixCursor(SEARCH_SUGGEST_COLUMNS, 1);
                cursor.addRow(new String[] {
                        "1", "Search Result", "Search Result Description", "content_id"
                });
                return cursor;
            default:
                throw new IllegalArgumentException("Unknown Uri: " + uri);
        }
    }

    @Override
    public int update(Uri uri, ContentValues arg1, String arg2, String[] arg3) {
        throw new UnsupportedOperationException();
    }
}

Then add your Places Autocomplete API client code into the query method on the content provider. You extract the user input as follows:

String query = uri.getLastPathSegment().toLowerCase();

Add the PlacesSuggestionProvider to your AndroidManifest, and make sure your activity has a searchable configuration.

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >

        <activity android:name=".PlacesSearchViewActivity" >
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

            <meta-data
                android:name="android.app.searchable"
                android:resource="@xml/searchable" />
        </activity>

        <provider
            android:name="com.example.google.places.PlacesSuggestionProvider"
            android:authorities="com.example.google.places.search_suggestion_provider"
            android:syncable="false" />
    </application>

</manifest>

And make sure your searchable configuration (res/xml/searchable.xml) has a search suggest authority.

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/search_hint"
    android:searchSuggestAuthority="com.example.google.places.search_suggestion_provider">
</searchable>

The authority should be the same in AndroidManifest.xml, searchable.xml, and your content provider.

Create a options menu for your ActionBar that includes a SearchView (/res/menu/options_menu.xml).

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_search"
          android:title="@string/menu_search"
          android:icon="@drawable/ic_menu_search"
          android:showAsAction="collapseActionView|ifRoom"
          android:actionViewClass="android.widget.SearchView" />
</menu>

Configure your Activity with a SearchView that's associated with your searchable configuration/

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the options menu from XML
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.options_menu, menu);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
    // Tells your app's SearchView to use this activity's searchable configuration
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default

    return true;
}

AutoCompleteTextView with google search Api

your xml

  <AutoCompleteTextView
    android:id="@+id/main_omnibox_input"

    android:selectAllOnFocus="true"
    android:singleLine="true" 
    android:textSize="@dimen/_14sdp" />

your java code

  this.inputBox = (AutoCompleteTextView) findViewById(R.id.main_omnibox_input);
  inputBox.setAdapter(new SearchAutocompleteAdapter(SearchActivity.this, new SearchAutocompleteAdapter.OnSearchCommitListener() {
        @Override
        public void onSearchCommit(String text) {
            inputBox.setText(text);
            inputBox.setSelection(text.length());
        }
    }));


    this.inputBox.setOnItemClickListener(new OnItemClickListener() {

I have a AutoCompleteTextView which gives user auto-completion search result from Google Places API. Once I was done I discovered SearchView and how it can be placed in the ActionBar. I checked out the SearchView example provided by google and added it to my application as a starting point (it lists the installed applications) but I don´t know how to proceed from here. I want to have the same functionality as AutoCompleteTextView but use the SearchView instead. Any suggestion? The whole class is provided below.

                Log.d("PlacesListActivity", "onPostExecute : result = " + string);
                adapter.add(string);
                adapter.notifyDataSetChanged();
            }

            Log.d("PlacesListActivity", "onPostExecute : autoCompleteAdapter" + adapter.getCount());
        }

    }

}

After updating the code suggested by saxman, I can see that the query method in the provider is never called:

I use the same authority in the manifest, content provider and manifest file. I see the searchView in the menu and I have not modified the query method so It should just return the one line cursor. but the query method is never called. please help. Another issue I just spotted is that the searchView does not show the specified search_hint!

Hi, just wondering, is there any advantage for using SearchView over AutoCompleteTextView for search functionality in action bar?
Fatima over 8 years

Terrific link for future vsitors; drzon.net/…

theAlse almost 12 years

thanks for the reply. So the content provider will do the looking up at Google Places and return a cursor! But I still don´t know how the searchView is connected to it?
saxman almost 12 years

Added that code as well (last 2 code blocks). In onCreateOptionsMenu, you configure the SearchView to use the searchable configuration you defined for your activity.
saxman almost 12 years

It sounds like you might be missing the last part: associating your searchable config with the SearchView. Please post your other files as well (searchable.xml, PlacesListSearchActivity, PlaceSuggestionProvider, and whatever you're using for the options menu).
theAlse almost 12 years

I have added pretty much all the classes. searchable.xml & PlacesSuggestionProvider.java is pretty much your original code.
saxman almost 12 years

You need an <intent-filter> around the <action android:name="android.intent.action.SEARCH" /> in your manifest.
theAlse almost 12 years

I will try this as soon as I get home ;) I can not believe I missed that and also I don´t understand why it did not complain!
theAlse almost 12 years

A follow up question, how do I use the previously used onPostExecute into the query-method of the content provider?
saxman almost 12 years

Not sure I follow... But you don't need to use an AsyncTask in your ContentProvider query method; calls to query(...) are off the UI thread. For my implementation, I have a PlacesService class that has "autocomplete", "getDetails", and "search" methods. I call autocomplete from the search suggest ContentProvider, but can also call it from other widgets, such as the AutoCompleteTextView.

How to find searchView onItemClickListner?
kellogs over 8 years

Thanks for the solution! A few comments: query method does run on the UI thread on API 19 at least. I am getting android.os.NetworkOnMainThreadException if ran just like that. Another issue I have spent 2 hours on: Replace the line public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/search"); with public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/" + SearchManager.SUGGEST_URI_PATH_QUERY); and all should be well
kellogs over 8 years

If going the way described above then the search query will not be available in String query = uri.getLastPathSegment().toLowerCase(); but instea you may take it irectly from the query method arguments
