android 常用uri

1.Uri通用资源标志符（Universal Resource Identifier, 简称"URI"）。Uri代表要操作的数据，Android上可用的每种资源 - 图像、视频片段等都可以用Uri来表示。URI一般由三部分组成：访问资源的命名机制。 存放资源的主机名。 资源自身的名称，由路径表示。 2 常用的Uri管理联系人的Uri：ContactsContract.Contacts.CONTENT_URI 管理联系人的电话的Uri：ContactsContract.CommonDataKinds.Phone.CONTENT_URI 管理联系人的Email的Uri：ContactsContract.CommonDataKinds.Email.CONTENT_URI （注：Contacts有两个表，分别是rawContact和Data，rawContact记录了用户的id和name,其中id栏名称为：ContactsContract.Contacts._ID, name名称栏为ContactContract.Contracts.DISPLAY_NAME,电话信息表的外键id为ContactsContract.CommonDataKinds.Phone.CONTACT_ID,电话号码栏名称为：ContactsContract.CommonDataKinds.Phone.NUMBER.data表中Email地址栏名称为：ContactsContract.CommonDataKinds.Email.DATA其外键栏为：ContactsContract.CommonDataKinds.Email.CONTACT_ID)关于多媒体的一些URI：存储在sd卡上的音频文件：MediaStore.Audio.Media.EXTERNAL_CONTENT_URI 存储在手机内部存储器上的音频文件：MediaStore.Audio.Media.INTERNAL_CONTENT_URI SD卡上的图片文件内容：MediaStore.Audio.Images.EXTERNAL_CONTENT_URI手机内部存储器上的图片：MediaStore.Audio.Images.INTERNAL_CONTENT_URISD卡上的视频：MediaStore.Audio.Video.EXTERNAL_CONTENT_URI 手机内部存储器上的视频：MediaStore.Audio.Video.INTERNAL_CONTENT_URI (注：图片的显示名栏：Media.DISPLAY_NAME，     图片的详细描述栏为：Media.DESCRIPTION     图片的保存位置：Media.DATA短信URI：Content://sms发送箱中的短信URI：Content://sms/outbox收信箱中的短信URI：Content://sms/sent草稿中的短信URI：Content://sms/draft常用代码：// 查询通讯录中联系人？ Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);// 获取手机号 Cursor phone = cursor.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+ ContactId, null, null);// 复杂点： Cursor phone = cursor.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+ ContactId +" AND "+ ContactsContract.CommonDataKinds.Phone.TYPE +"="+ ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null, null);ContactsContract.CommonDataKinds.Phone.TYPE 表示联系人电话的类型，主要对应如下：    TYPE_MOBILE ： 手机号码    TYPE_HOME ： 住宅电话    TYPE_WORK ： 公司电话打开一个网页，类别是Intent.ACTION_VIEWUri uri =
