内容提供者URI匹配器

Question

在实施ContentProvider时，在文档中有明确的推荐用于定义所有uris。但我对URI匹配器部分感到困惑：例如，我有包org.company.example，表名为'items'，然后我定义

 public static final Uri CONTENT_URI = 
  Uri.parse("content://org.company.example.sampleprovider/items");

我应该使用什么权限部分来匹配静态init中的URI：

 private static final UriMatcher uriMatcher;

  static {
   uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
   uriMatcher.addURI("what goes here?", "items", ITEM);
   uriMatcher.addURI("what goes here?", "items/#", ITEM_ID);
  }

Answer 1

public static final String PROVIDER_NAME = "org.company.example.sampleprovider";
public static final Uri CONTENT_URI = Uri.parse("content://" + PROVIDER_NAME);
private static final UriMatcher uriMatcher;
static {
   uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
   uriMatcher.addURI(PROVIDER_NAME, "items", ITEM);
   uriMatcher.addURI(PROVIDER_NAME, "items/#", ITEM_ID);
}
