Provider需要的Uri类描述

Uri类所在包android.net

Uri定义

/** 访问音乐播放器provider的AUTHORITY */public static final String AUTHORITY = "cn.com.mymusicplay.provider";/** content://uri 类型的 AUTHORITY音乐播放器provider */public static final Uri AUTHORITY_URI = Uri.parse("content://" + AUTHORITY);public static final String MUSIC_DIRECTORY = "music";/** 歌曲URI */public static final Uri MUSIC_URI = Uri.withAppendedPath(AUTHORITY_URI, MUSIC_DIRECTORY);

Uri与Sring互相转换

String uriStr=uri.toString();uri=Uri.parse(uriStr);

获取Uri里的值

Uri uri = MyMusicPlayerContract.DGROUP_URI;String str = uri.toString();System.out.println("toString() " + str);str = uri.getAuthority();System.out.println("getAuthority() " + str);str = uri.getEncodedAuthority();System.out.println("getEncodedAuthority() " + str);str = uri.getEncodedFragment();System.out.println("getEncodedFragment() " + str);str = uri.getEncodedPath();System.out.println("getEncodedPath() " + str);str = uri.getEncodedQuery();System.out.println("getEncodedQuery() " + str);str = uri.getEncodedSchemeSpecificPart();System.out.println("getEncodedSchemeSpecificPart() " + str);str = uri.getEncodedUserInfo();

System.out.println("getEncodedUserInfo() " + str);str = uri.getFragment();System.out.println("getFragment() " + str);str = uri.getHost();System.out.println("getHost() " + str);str = uri.getLastPathSegment();System.out.println("getLastPathSegment() " + str);str = uri.getPath();System.out.println("getPath() " + str);str = uri.getQuery();System.out.println("getQuery() " + str);str = uri.getScheme();System.out.println("getScheme() " + str);str = uri.getSchemeSpecificPart();System.out.println("getSchemeSpecificPart() " + str);str = uri.getUserInfo();System.out.println("getUserInfo() " + str);List<String> pathSegments = uri.getPathSegments();System.out.println("getPathSegments() " + pathSegments);int port = uri.getPort();System.out.println("getPort() " + port);
