1 つの方法は、ソース コードを からコピーしandroid.content.SearchRecentSuggestionsProvider
、ContentProvider を拡張するクラスに配置して、setupSuggestions(String, int)
. 具体的には、次のように変更します。
Uri uriFile = Uri.fromFile(new File("path/to/file"));
mSuggestionProjection = new String [] {
"0 AS " + SearchManager.SUGGEST_COLUMN_FORMAT,
// Here, you would return a file uri: 'uriFile'
"'android.resource://system/"
+ com.android.internal.R.drawable.ic_menu_recent_history + "' AS "
+ SearchManager.SUGGEST_COLUMN_ICON_1,
"display1 AS " + SearchManager.SUGGEST_COLUMN_TEXT_1,
"query AS " + SearchManager.SUGGEST_COLUMN_QUERY,
"_id"
};
私は次のことを好みます。メソッドを拡張SearchRecentSuggestionsProvider
してオーバーライドしますquery(...)
。SearchManager.SUGGEST_URI_PATH_QUERY
ここでは、カーソルをインターセプトして返します。
public class SearchSuggestionProvider extends SearchRecentSuggestionsProvider {
private UriMatcher matcher;
private static final int URI_MATCH_SUGGEST = 1;
public SearchSuggestionProvider() {
super();
matcher = new UriMatcher(UriMatcher.NO_MATCH);
// Add uri to return URI_MATCH_SUGGEST
matcher.addURI(SearchSuggestionProvider.class.getName(),
SearchManager.SUGGEST_URI_PATH_QUERY, URI_MATCH_SUGGEST);
setupSuggestions(SearchSuggestionProvider.class.getName(),
DATABASE_MODE_QUERIES);
}
@Override
public Cursor query(Uri uri, String[] projection, String selection,
String[] selectionArgs, String sortOrder) {
// special case for actual suggestions (from search manager)
if (matcher.match(uri) == URI_MATCH_SUGGEST) {
// File to use
File f = new File("/path/to/file");
Uri uriFile = Uri.fromFile(f);
final String[] PROJECTION = new String[] {
"_id",
"display1 AS " + SearchManager.SUGGEST_COLUMN_TEXT_1,
"query AS " + SearchManager.SUGGEST_COLUMN_QUERY,
"'" + uriFile + "'" + " AS " + SearchManager.SUGGEST_COLUMN_ICON_1,
};
final Uri URI = Uri.parse("content://" +
SearchSuggestionProvider.class.getName() + "/suggestions");
// return cursor
return getContext().getContentResolver().query(
URI,
PROJECTION,
"display1 LIKE ?",
new String[] {selectionArgs[0] + "%"},
"date DESC");
}
// Let super method handle the query if the check fails
return super.query(uri, projection, selection, selectionArgs, sortOrder);
}
}
