はい、SearchRecentSuggestionsProviderを独自のクラスで拡張できます。これは私がこれを行うために書いたクラスです:https ://github.com/bostonbusmap/bostonbusmap/blob/master/src/boston/Bus/Map/provider/TransitContentProvider.java
package boston.Bus.Map.provider;
import boston.Bus.Map.data.RoutePool;
import boston.Bus.Map.main.Main;
import boston.Bus.Map.provider.DatabaseContentProvider.DatabaseAgent;
import boston.Bus.Map.transit.TransitSystem;
import android.app.SearchManager;
import android.content.ContentProvider;
import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.SearchRecentSuggestionsProvider;
import android.content.UriMatcher;

public class TransitContentProvider extends SearchRecentSuggestionsProvider {
private UriMatcher matcher;
public static final String AUTHORITY = "com.bostonbusmap.transitprovider";
public static final int MODE = SearchRecentSuggestionsProvider.DATABASE_MODE_QUERIES;
private static final int SUGGESTIONS_CODE = 5;
public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY);
public TransitContentProvider()
{
matcher = new UriMatcher(UriMatcher.NO_MATCH);
matcher.addURI(AUTHORITY, SearchManager.SUGGEST_URI_PATH_QUERY, SUGGESTIONS_CODE);
setupSuggestions(AUTHORITY, MODE);
}
@Override
public boolean onCreate() {
boolean create = super.onCreate();
return create;
}
@Override
public Cursor query(Uri uri, String[] projection, String selection,
String[] selectionArgs, String sortOrder)
{
int code = matcher.match(uri);
switch (code)
{
case SUGGESTIONS_CODE:
if (selectionArgs == null || selectionArgs.length == 0 || selectionArgs[0].trim().length() == 0)
{
return super.query(uri, projection, selection, selectionArgs, sortOrder);
}
else
{
ContentResolver resolver = getContext().getContentResolver();
return DatabaseAgent.getCursorForSearch(resolver, selectionArgs[0]);
}
default:
return super.query(uri, projection, selection, selectionArgs, sortOrder);
}
}
}
