内容提供商URI匹配器

Question

在实施ContentProvider时定义所有uris的文档中有独特的建议。但我很困惑与URI匹配的部分：比如，我有包​​，表命名为“项”，然后我定义

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

我应该使用什么授权部分匹配静态初始化的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); 
}
