Android URI简介

Android平台而言,URI主要分三个部分:scheme, authority and path。其中authority又分为host和port。格式如下:
scheme://host:port/path
举个实际的例子:
content://com.example.project:200/folder/subfolder/etc
\---------/  \---------------------------/ \---/ \--------------------------/
scheme                 host               port        path
                \--------------------------------/
                          authority   

现在大家应该知道data flag中那些属性的含义了吧,看下data flag
<data android:host="string"
      android:mimeType="string"
      android:path="string"
      android:pathPattern="string"
      android:pathPrefix="string"
      android:port="string"
      android:scheme="string" />
但是我们在程序中一般是不直接用URI来标识CP的,是的,正如我们通常见到的用定义的常量来标识。例如standard CP中的Contacts,我们就用Contacts.People.CONTENT_URI来标识Contacts CP中People这个表。那么要标识某个具体的人怎么办呢? 这就用到了ContentUris.withAppendedId() 和 Uri.withAppendedPath()。例如我们要表示content://contacts/people/20,那么我们就可以用如下语句:
Uri uri = ContentUris.withAppendedId(People.CONTENT_URI, 20); 或者
Uri uri = Uri.withAppendedPath(People.CONTENT_URI, "20");

 

举些例子,如:

所有联系人的Uri: content://contacts/people

某个联系人的Uri: content://contacts/people/5

所有图片Uri: content://media/external

某个图片的Uri:content://media/external/images/media/4

下面是一些常用的Uri
