Transformez AutoCompleteTextView en SearchView dans ActionBar à la place

J'ai un AutoCompleteTextView qui donne le résultat de la recherche de saisie semi-automatique de l'utilisateur de Google Places API. Une fois que j'ai fini, j'ai découvert SearchView et comment le placer dans ActionBar. J'ai vérifié l'exemple SearchView fourni par Google et l'ai ajouté à mon application comme point de départ (il répertorie les applications installées) mais je ne sais pas comment procéder à partir d'ici. Je veux avoir les mêmes fonctionnalités que AutoCompleteTextView mais utiliser plutôt SearchView. Toute suggestion? La classe entière est fournie ci-dessous.

J'utilise la même autorité dans le manifeste, le fournisseur de contenu et le fichier manifeste. Je vois le searchView dans le menu et je n'ai pas modifié la méthode de requête donc il devrait simplement retourner le curseur d'une ligne. mais la méthode de requête n'est jamais appelée. veuillez aider. Un autre problème que je viens de remarquer est que le searchView n'affiche pas le search_hint spécifié!

    @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();
    }
}

Ajoutez ensuite votre code client API de saisie semi-automatique Places dans la méthode de requête du fournisseur de contenu. Vous extrayez l'entrée utilisateur comme suit:

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

Ajoutez le PlacesSuggestionProvider à votre AndroidManifest et assurez-vous que votre activité a une configuration consultable.

    <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>

Et assurez-vous que votre configuration consultable (res/xml/searchable.xml) dispose d'une autorité de suggestion de recherche.

<?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>

L'autorité doit être la même dans AndroidManifest.xml, searchable.xml et votre fournisseur de contenu.

Créez un menu d'options pour votre ActionBar qui inclut un 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>

Configurez votre activité avec une SearchView associée à votre configuration consultable /

@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;
}
