Description

一种基于滑动检测的数据传输方法及装置 技术领域
本发明涉及网络通信技术领域, 特别涉及一种基于滑动检测的数据 传输方法及装置。 发明背景
随着网络技术的发展, 互联网已经深入到广大的网络用户心中。 在 众多的互联网应用中, 通过消息客户端进行信息传播与分享已经成为广 大网络用户的生活工作及休闲中不可或缺的部分。 在基于消息客户端的 通信过程中, 通常有大量的消息(例如文本信息、 图片信息和音 /视频信 息等)需要传输。
微博, 即微博客( Micro Blog ), 就是一种采用上述消息客户端进行 信息传播的系统, 它是一个基于用户关系的即时的信息分享、 传播及获 取平台。 用户可以通过手机、 电脑等终端设备登录微博客户端, 从而实 现信息共享。
考虑到微博的即时性, 手机自然成了微博的最好的载体之一。 当用 户使用手机浏览微博消息时, 通常会做一些滑动操作。 这样, 一些原来 在屏幕之外的微博消息就会滑动到屏幕中来。
在微博系统中, 消息是由消息信元(Message Cell )来承载的。通常, 每个 Message Cell包括消息内容、消息发表人的名称及发表人的头像等。 多个 Message Cell按照时间顺序形成一个列表 ( Timeline ) , 并展示在手 机屏幕上。
当用户进行屏幕滑动操作时, 原来在屏幕之外的 Message Cell就会 滑动到屏幕中来。 对于在滑动过程中进入到屏幕中来的每个 Message Cell, 微博客户端都要下载该 Message Cell对应的消息内容、 发表人的 名称和发表人的头像。
而当用户进行连续快速的滑动操作时,就会导致大量的 Message Cell 从屏幕外滑动到屏幕中来并再次滑动出屏幕。 这样, 微博客户端就需要 下载各个曾经到过屏幕中来的 Message Cell对应的消息内容、 发表人的 名称及头像。 然而, 用户此时关心的并不是在连续快速的滑动过程中曾 经到过屏幕中来的那些 Message Cell, 而是当滑动操作结束时, 屏幕上 显示的那些 Message Cell。 这样, 大量的网络资源浪费在了滑动过程中 到过屏幕中来的那些 Message Cell对应的消息内容和 /或发表人头像的下 载上,尤其是当 Message Cell对应的消息内容包含图片或音 /视频等数据 量较大的文件时。
对于采用按数据流量收费方式接入网络的手机用户来说, 上述的下 载过程给用户带来了大量的数据流量的浪费及较差的用户体验。
同理, 对于采用 3G等无线方式接入网络的电脑用户来说, 也存在 着同样的问题。 发明内容
有鉴于此,本发明提供了一种基于滑动检测的数据传输方法及装置, 从而降低网络数据流量, 改善用户的体验。
本发明提供的一种基于滑动检测的数据传输方法包括:
当检测到消息信元列表 Timeline在用户终端的屏幕上滚动时,消息 客户端记录在屏幕中可见的消息信元 Message Cell;
消息客户端判断该 Message Cell在预定时间后是否仍然在屏幕上可 见; 如果是, 从消息服务器下载该 Message Cell对应的数据。
本发明提供的一种基于滑动检测的数据传输装置包括: 检测模块、 记录模块、 判断模块和下载模块; 其中,
检测模块用于检测 Timeline是否在用户终端的屏幕上滚动; 记录模块用于当检测模块检测到 Timeline在用户终端的屏幕上滚 动时, 记录在屏幕中可见的 Message Cell;
判断模块用于判断记录模块记录的 Message Cell在预定时间后是否 仍然在屏幕上可见;
下载模块用于当判断模块判断出 Message Cell在预定时间后仍然在 屏幕上可见时, 从消息服务器下载该 Message Cell对应的数据。
通过本发明提供的基于滑动检测的数据传输方法及装置, 仅当 Message Cell在屏幕中停留的时间达到预定的定时时间时, 才触发下载 该 Message Cell对应的数据。 这样, 可以避免下载那些滑动到屏幕中来 又快速滑动到屏幕之外的 Message Cell对应的数据, 从而大幅度的降低 用户的网络数据流量, 改善用户的体验。 附图简要说明

为使本发明的目的、 技术方案及优点更加清楚明白, 以下参照附图 并举实施例, 对本发明进一步详细说明。
本发明的核心思想是: 当检测到消息信元列表(Timeline )在用户 终端的屏幕上滚动时, 消息客户端记录在屏幕中可见的消息信元 ( Message Cell ); 判断该 Message Cell在预定时间后是否仍然在屏幕中 可见; 如果是, 从消息服务器下载该 Message Cell对应的数据。 这样, 可以避免下载那些滑动到屏幕中来又快速滑动到屏幕之外的 Message Cell对应的数据, 从而大幅度的降低用户的网络数据流量, 改善用户的 体验。
图 1 为本发明实施例中一种基于滑动检测的数据传输方法的流程 图。 如图 1所示, 该方法包括:
步骤 101 , 当检测到 Timeline在用户终端的屏幕上滚动时, 消息客 户端记录在屏幕中可见的 Message CelL
步骤 102, 消息客户端判断该 Message Cell在预定时间后是否仍然 在屏幕上可见。 如果是, 执行步骤 103; 否则, 结束本流程。
步骤 103 , 从消息服务器下载该 Message Cell对应的数据。
其中, 用户终端可以是手机、 电脑等设备; 消息客户端可以是微博 客户端; 相应的, 消息服务器可以是微博服务器; Message Cell对应的 数据可以是 Message Cell对应的消息内容中包含的图片、或者音 /视频文 件, 还可以是 Message Cell对应的消息发表人的头像。
下面以用户通过手机登录微博客户端且 Message Cell对应的数据为 消息发表人的头像为例, 对本发明提供的基于滑动检测的数据传输方法 进行详细描述。
图 2 为本发明实施例中一种基于滑动检测的数据传输方法的流程 图。 如图 2所示, 该方法包括以下步骤:
步骤 201 , 微博客户端检测 Timeline是否在手机屏幕上滚动, 如果 检测到 Timeline在手机屏幕上滚动, 则执行步骤 202; 否则, 重复执行 步骤 201。
以 iphone手机为例, Timeline作为控件会以 iphone手机所用的 ios 系统提供的滚动视图控件做为载体。 当 Timeline滚动开始, ios系统会 触发视图滚动开始事件通知微博客户端滚动视图开始滚动。 滚动停止 时, ios系统会触发视图滚动结束事件来告诉微博客户端滚动视图停止滚 动。从而, 微博客户端可以知道到 Timeline是否在手机屏幕上滚动。 具 体的,在 iphone手机所用的 ios系统中,滚动视图控件可以是 scrollview, 视图滚动开始事件可以是 scrollviewDidscroll,视图滚动结束事件可以是 scrollviewDidEndDecelerating。
本领域技术人员也可以根据实际情况选择其他方法来检测 Timeline 是否在手机屏幕上滚动。 本发明对具体的检测方法没有限定。
步骤 202, 微博客户端记录在手机屏幕上可见的 Message Cell, 并启 动定时器。
仍然以 iphone手机为例, 当一个 Message Cell进入屏幕时, ios系统 会触发事件来通知微博客户端。 在收到通知之后, 微博客户端即可以判 断出该 Message Cell 在手机屏幕上是可见的。 具体的, 该事件可以是 cellForRowAtIndexPath。 此时, 博客户端记录该 Message Cell的标识, 并同时启动定时器。 当一个 Message Cell滑动到屏幕之外时, ios系统也 会通知微博客户端。在收到通知之后,微博客户端可以判断出该 Message Cell滑动出了屏幕。
在本步骤中,随着 Timeline的滚动,手机屏幕上可能有多个 Message Cell 可见。 则微博客户端在每个 Message Cell在进入屏幕时, 记录该 Message Cell的标识并同时启动该 Message Cell对应的定时器。
例如, 当 Timeline在手机屏幕上滚动时, Message Cell 1首先进入 屏幕。 此时, 微博客户端记录 Message Cell 1对应的标识 IDl , 并启动 Message Cell 1对应的定时器 Tl。然后, 随着 Timeline的滚动, Message Cell 2进入屏幕。此时,微博客户端记录 Message Cell 2对应的标识 ID2, 并启动 Message Cell 2对应的定时器 T2 , 以此类推。
其中, 在屏幕上可见的各个 Message Cell对应的标识可以存储在一 个数组中。例如,在某个时刻,屏幕上可见的 Message Cell包括 Message Cell 1 , Message Cell 2和 Message Cell 3 , 此时, 该数组的内容包括 ID1 , ID2和 ID3。在另一时刻, 随着 Timeline的滚动, Message Cell 1滑动出 了屏幕之外, 同时 Message Cell 4滑动到了屏幕中来。 此时, 该数组的 内容包括 ID2, ID3和 ID4。
步骤 203 , 显示本地存储的默认头像。
具体的, 微博客户端可以判断本地是否存储有 Message Cell对应的 发表人的头像。 如果有, 则默认头像为本地存储的该 Message Cell对应 的发表人的头像。 此时, 微博客户端显示本地存储的该 Message Cell对 应的发表人的头像。 如果本地没有存储该 Message Cell对应的发表人的 头像, 则微博客户端可以显示本地存储的系统默认的头像。
步骤 204, 微博客户端判断 Message Cell对应的定时器是否到时, 如果是, 则执行步骤 205; 否则, 重复执行步骤 204。
在本步骤中, 定时器的时长可以根据实际情况设定。 优选的, 可以 设定为 0-1秒之间, 此时, 可以达到较好的视觉效果。 另外,各个 Message Cell对应的定时器的时长可以相同也可以不同。 如果微博客户端在步骤 202中记录了多个 Message Cell并启动了多 个定时器, 则在本步骤中, 微博客户端分别判断每个 Message Cell对应 的定时器是否到时。
步骤 205 , 判断 Message Cell是否仍然在屏幕中可见。 如果可见, 执行步骤 206; 否则, 结束本流程。
具体的, 微博客户端可以通过判断上述的数组中是否包含该 Message Cell对应的标识来判断该 Message Cell是否仍然在屏幕中可见。
例如, 对于 Message Cell 1 , 如果 Message Cell 1对应的定时器 Tl 的定时时间到, 微博客户端判断数组中是否包含 Message Cell 1对应的 标识 ID1。 如果包含, 则说明 Message Cell 1仍然在屏幕中可见; 否贝' J , 说明 Message Cell 1在屏幕中不可见, 即已经滑动出了屏幕。
步骤 206, 微博客户端更新所显示的头像。
具体的, 如果步骤 203中判断出本地存储有该 Message Cell对应的 发表人的头像, 微博客户端判断该 Message Cell对应的发表人的头像的 下载地址是否与本地存储的下载地址相同。 如果相同, 说明该 Message Cell 对应的发表人的头像没有更新, 结束本流程。 如果不同, 说明该 Message Cell对应的发表人的头像已经更新, 则微博客户端从微博服务 器下载更新的头像, 并显示该更新的头像以替换步骤 203中显示的本地 存储的该 Message Cell对应的发表人的头像。
如果步骤 203中判断出本地没有存储该 Message Cell对应的发表人 的头像, 则微博客户端直接从微博服务器下载该 Message Cell对应的发 表人的头像, 然后显示该下载的头像以替换步骤 203中的系统默认的头 像。
通过本发明的实施例可以看出, 仅当 Message Cell在屏幕中停留的 时间达到预定的定时时间时, 才触发下载该 Message Cell对应的发表人 的头像。 这样, 可以避免下载那些滑动到屏幕中来又快速滑动到屏幕之 外的 Message Cell对应的发表人的头像, 从而大幅度的降低用户的网络 数据流量。
此外, 在本发明中, Message Cell对应的数据也可以为 Message Cell 对应的消息内容中包含的图片、 音 /视频等大数据量文件。 图 3为本发明 另一实施例中一种基于滑动检测的数据传输方法的流程图。 在本实施例 中, 仍然以手机用户登录微博客户端为例。 如图 3所示, 该方法包括: 步骤 301-302与步骤 201-202相同。
步骤 303 , 微博客户端显示本地存储的默认图片。
步骤 304-305与步骤 204-205相同。
步骤 306, 微博客户端从微博服务器下载 Message Cell对应的消息 内容包含的图片或音 /视频文件,并在手机屏幕上显示所下载的图片或者 音 /视频文件以替代步骤 303中显示的默认图片。
这样, 如果该 Message Cell很快滑动出屏幕之外, 可以避免下载这 些大数据量的文件, 从而降低用户的网络数据流量。
以上对本发明实施例提供的基于滑动检测的数据传输方法进行了描 述。 下面将结合附图和具体实施例对本发明提供的基于滑动检测的数据 传输装置进行具体描述。
图 4为本发明实施例中一种基于滑动检测的数据传输装置的结构示 意图。 如图 4所示, 该装置包括: 检测模块 401、 记录模块 402、 判断 模块 403和下载模块 404。
检测模块 401用于检测 Timeline是否在用户终端的屏幕上滚动。 记录模块 402用于当检测模块 401检测到 Timeline在用户终端的屏 幕上滚动时, 记录在屏幕中可见的 Message Cell。 判断模块 403用于判断记录模块 402记录的 Message Cell在预定时 间后是否仍然在屏幕上可见。
下载模块 404用于当判断模块 403判断出 Message Cell在预定时间 后仍然在屏幕上可见时,从消息服务器下载该 Message Cell对应的数据。
具体的, 本发明实施例提供的装置可以是微博客户端; 对应的, 上 述的消息服务器可以为微博服务器。 上述的 Message Cell对应的数据可 以是 Message Cell对应的消息内容中包含的图片、 或者音 /视频文件, 还 可以是 Message Cell对应的消息发表人的头像。

检测模块 501 , 用于检测 Timeline是否在手机屏幕上滚动。 如果检 测到 Timeline在手机屏幕上滚动, 则通知判断模块 502; 否则, 重复进 行检测。
判断模块 502,用于在收到检测模块 501的通知后,判断 Message Cell 是否进入屏幕,在 Message Cell进入屏幕时发送进入通知给记录模块 503 和显示模块 506, 并触发定时器模块 504开始计时。 此外, 判断模块 502 进一步用于判断 Message Cell是否离开屏幕, 并在 Message Cell离开屏 幕时发送离开通知给记录模块 503。
记录模块 503 , 用于在收到判断模块 502的进入通知后, 记录进入 手机屏幕的 Message Cell的标识。具体的,记录模块 503可以将 Message Cell的标识记录在一个数组中。当有多个 Message Cell进入手机屏幕时, 该数组用于记录各个 Message Cell的标识。 此外, 记录模块 503进一步 用于当收到判断模块 502的离开通知后, 从数组中删除对应的 Message Cell的标识。
定时器模块 504, 用于在判断模块 502的触发下开始计时。 具体的, 定时器模块 504可以包括多个定时器单元, 分别对应于记录模块 503记 录的各个 Message Cell。 例如, 当 Message Cell 1进入了屏幕时, 对应于 Message Cell 1的定时器单元 5041开始计时。
当定时器模块 504的定时时间到时,判断模块 502判断 Message Cell 是否仍然在屏幕上可见。 具体的, 判断模块 502可以发送查询消息给记 录模块 503。 记录模块 503收到查询消息后, 判断数组中是否记录有该 Message Cell对应的标识,并返回查询结果给判断模块 502。如果查询结 果指示数组中记录有该 Message Cell对应的标识, 则判断模块 502可以 判断出该 Message Cell仍然在屏幕上可见; 否则, 判断模块 502可以判 断出该 Message Cell在屏幕上不可见, 即已经滑动出了屏幕。
存储模块 505 , 用于存储默认头像和下载模块 507下载的头像。 具 体的, 当存储模块 505存储有 Message Cell对应的发表人的头像时, 则 默认头像为存储模块 505存储的该 Message Cell对应的发表人的头像。 如果存储模块 505没有存储 Message Cell对应的发表人的头像, 则默认 头像为存储模块 505中存储的系统默认的头像。
下载模块 507, 用于当判断模块 502判断出 Message Cell在定时器 模块 504的定时时间到后仍然在屏幕上可见时, 判断存储模块 505是否 存储有该 Message Cell对应的发表人的头像, 如果有, 判断该 Message Cell对应的发表人的头像的是否已经更新, 如果是, 则从微博服务器下 载更新的头像, 并发送给存储模块 505和显示模块 506; 如果存储模块 505没有存储该 Message Cell对应的发表人的头像, 则从微博服务器下 载该 Message Cell对应的发表人的头像, 并发送给存储模块 505和显示 模块 506。
显示模块 506, 用于在收到判断模块 502的进入通知时, 显示存储 模块 505存储的默认头像, 当接收到下载模块 507发送的头像时, 显示 从下载模块 507接收到的头像以替代所显示的默认头像。
此外, 对应图 3所示的实施例, 本发明实施例还提供了另一种基于 滑动检测的数据传输装置。 如图 6所示, 该装置包括: 检测模块 601、 判断模块 602、 记录模块 603、 定时器模块 604、 存储模块 605、 显示模 块 606及下载模块 607。
其中, 检测模块 601、 判断模块 602、 记录模块 603及定时器模块 604的功能与图 5中对应模块的功能相同, 在此不再赘述。
存储模块 605用于存储默认图片。
下载模块 607用于当判断模块 602判断出 Message Cell仍然在屏幕 上可见时, 从微博服务器下载 Message Cell对应的消息内容中包含的图 片或音 /视频文件, 并发送给显示模块 606。
显示模块 606用于当收到判断模块 602的进入通知时, 显示存储模 块 605存储的默认图片, 当收到下载模块 607发送的图片或音 /视频文件 时,显示从下载模块 607接收到的图片或者音 /视频文件以替代之前显示 的默认图片。
以上仅以用户通过手机登录微博客户端为例, 对本发明提供的基于 滑动检测的数据传输方法及装置进行了描述。 需要说明的是, 本发明并 不仅限于用户通过手机登录微博客户端的情况。
