具体实施例
下面结合附图和具体的实施方式对本发明作进一步的描述。
在本发明的实施例中, 由客户端记录用户数据, 由服务器端根据客户端记录的 数据并结合服务器端的数据生成安全网址导航列表, 再由客户端展示给用户。
参见图 1, 示意性地示出了根据本发明一个实施例的切换终端桌面背景的客户 端。 该客户端 2000包括: 图片下载模块 100、 存储模块 300、 挂件呈现模块 200、 指 令接收模块 400和壁纸切换模块 500。
图片下载模块 100, 适于从服务器 1000下载壁纸图片, 存储下载的壁纸图片到 存储模块 300。
进一步地, 图片下载模块 100, 还适于当下载的壁纸图片数量没有达到第一预 设阀值时, 指示挂件呈现模块 200 不呈现挂件图标和位于挂件图标上方的吊绳, 当 下载的壁纸图片数量达到第一预设阀值时, 指示挂件呈现模块 200 在屏幕中呈现处 于通常状态的挂件图标和位于挂件图标上方的吊绳。
例如, 第一预设阀值为 5, 图片下载模块 100在下载的壁纸图片数量没有达到 5 时, 指示挂件呈现模块 200 不呈现挂件图标和位于挂件图标上方的吊绳, 当下载的 壁纸图片数量达到 5 时, 指示挂件呈现模块 200在屏幕中呈现处于通常状态的挂件 图标和位于挂件图标上方的吊绳。
进一步地, 图片下载模块 100, 还适于当存储的壁纸图片中未被提取过的壁纸 图片的数量小于第二预设阀值时, 从服务器 1000下载第一预设数量的壁纸图片, 将 该下载的壁纸图片存储到存储模块 300。
如后所述, 在本实施例中, 壁纸切换模块 500提取存储模块 300存储的壁纸图 片, 将该壁纸图片设置为桌面背景。 当存储的壁纸图片中未被提取过的壁纸图片的 数量小于第二预设阀值时, 从服务器 1000下载第一预设数量的壁纸图片。 由此, 能 够使得存储的壁纸图片中具有一定数量的未被提取过的壁纸图片, 以保证壁纸切换 模块 500在进行桌面背景切换时提取未被提取过的壁纸图片。
例如, 第二预设阀值为 4, 第一预设数量为 5, 图片下载模块 100将下载的壁纸 图片存储到存储模块 300 的壁纸图片队列中, 对壁纸图片队列中壁纸图片的提取进 行记录, 当未被提取过的壁纸图片的数量小于 4时, 图片下载模块 100 自动从服务 器 1000下载 5张的壁纸图片。 如果因为拉动挂件过快, 导致从服务器 1000下载新 的壁纸图片的速度跟不上桌面背景切换速度, 在这种情况下, 壁纸切换模块 500 提 取存储模块 300 存储的已经提取过的壁纸图片进行桌面背景切换, 以保持挂件拉动 与桌面背景切换间的关联性, 进而保证 "下拉挂件-释放挂件 -背景切换" 的连贯性和 一致性。
通过上述预下载方式, 能够提高桌面背景的切换速度, 因为壁纸图片已经被下 载到客户端本地, 因此在挂件图标被下拉并释放后, 便可直接进行桌面背景切换, 不必再等待壁纸图片下载完成。
存储模块 300, 适于存储下载的壁纸图片。
挂件呈现模块 200, 适于在屏幕中呈现通常状态下的挂件图标和位于挂件图标 上方的吊绳。 该通常状态为挂件图标没有被拉动的状态。
指令接收模块 400, 适于接收对挂件图标进行操作的指令, 将接收的指令发送 给挂件呈现模块 200。
挂件呈现模块 200, 还适于当从指令接收模块 400接收到向下拉动屏幕中挂件 图标的指令后, 依据指令中向下拉动的拉伸位移将挂件图标向下移动, 并延伸挂件 图标上方的吊绳, 直到挂件图标移动到预设的下方极限位置或指令中向下拉动停止, 挂件图标进入拉伸状态; 当在挂件图标的拉伸状态下从指令接收模块 400 接收到释 放挂件图标的指令后, 向上移动挂件图标, 并收縮挂件图标上方的吊绳, 直到挂件 图标上移到未被拉伸前的位置, 挂件图标恢复到通常状态, 并指示壁纸切换模块 500 进行壁纸切换。
参见图 2, 为根据本发明一个实施例的在通常状态下和拉伸状态下呈现的挂件 的示意图。 屏幕中呈现挂件图标 220和位于挂件图标上方的吊绳 210。
在通常状态下, 挂件图标中参考点的 Y轴坐标为 y0, 在预设的下方极限位置处 参考点的 Y轴坐标为 yl。
首先, 从指令接收模块 400接收到向下拉动屏幕中挂件图标的指令, 该指令可 以为鼠标向下拖拉挂件图标后触发的指令。 此时, 挂件呈现模块 200 将挂件图标从 通常状态下, 图 2 中左边所示的通常状态下, 随鼠标的向下拖拉而移动, 当挂件图 标中参考点的坐标达到 yl或鼠标停止拖拉时, 挂件图标不再沿 Y轴向下进行移动, 此时挂件图标进入拉伸状态, 如图 2右边所示。
然后, 从指令接收模块 400接收到释放挂件图标的指令, 该指令可以为鼠标释 放挂件图标后触发的指令。 挂件呈现模块 200 将挂件图标向上移动, 并收縮挂件图 标上方的吊绳, 当挂件图标中参考点的坐标达到 yO时, 挂件图标上移到未被拉伸前 的位置, 恢复到通常状态, 即图 2中左边所示的状态。
壁纸切换模块 500, 适于从存储模块 300存储的壁纸图片中提取一张壁纸图片, 将该壁纸图片设置为桌面背景。
进一步地, 壁纸切换模块 500优先从存储的壁纸图片中提取未被提取过的壁纸 图片, 将该壁纸图片设置为桌面背景。
当存储模块 300中没有未被提取过的壁纸图片时, 壁纸切换模块 500提取存储 模块 300 存储的已经提取过的壁纸图片进行桌面背景切换, 以保持挂件拉动与桌面 背景切换间的关联性,进而保证 "下拉挂件-释放挂件 -背景切换"的连贯性和一致性。
举例而言, 挂件呈现模块 200可以通过挂件图片实现呈现挂件图标和吊绳。 该 挂件图片中包含挂件图标和位于挂件图标上方的吊绳。 此处仅为举例说明, 本发明 对此没有特別限制, 也可以采用其他方式呈现挂件图标和吊绳。 例如, 可以根据指 令对挂件图标和吊绳进行重画, 以呈现挂件图标被下拉或释放的效果。
挂件呈现模块 200设置不呈现挂件图片的不可见区域在屏幕中的位置, 将挂件 图片中从顶部向下预设长度的部分设置在不可见区域内, 在屏幕中呈现挂件图片。
参见图 3, 根据本发明一个实施例的通过挂件图片呈现挂件图标的示意图。 在 屏幕的最顶部之外设置不可见区域, 挂件图片在不可见区域的部分 310 不显示, 挂 件图片的尺寸为 40px X 80px, 在通常状态下, 挂件图片从顶部向下 25px的部分 310 位于不可见区域内。 其中, 挂件图片的背景与屏幕中呈现挂件的区域处的背景相同 或者挂件图片的背景设置为透明, 采用挂件图片呈现挂件的效果如图 4 所示。 图 4 中, 每組挂件中左侧为通常状态, 右侧为拉伸状态, 实际显示中, 每組中只显示一 个挂件, 该挂件如左侧所示, 处于通常状态, 或如右侧所示, 处于拉伸状态。
挂件呈现模块 200从指令接收模块 400接收到向下拉动屏幕中挂件图标的指令 后, 依据指令中向下拉动的拉伸位移将挂件图片向下移动, 直到挂件图标移动到预 设的下方极限位置或指令中向下拉动停止; 当在拉伸状态下从指令接收模块 400 接 收到释放挂件图标的指令后, 向上移动挂件图片到未被向下移动前的位置。 由此, 通过移动挂件图片实现挂件被拉伸和收縮的效果。
由于挂件在屏幕中所占空间较小, 因此本实施例解决了在桌面背景切换后无法 及时获得切换后的桌面背景效果的技术问题, 又由于通过简单的拉动释放挂件便可 以实现桌面背景切换, 因此本实施例解决了切换终端桌面背景的操作复杂的技术问 题。 进而, 本实施例取得了在桌面背景切换后能够及时获得切换后的桌面背景效果 和切换终端桌面背景的操作简单易行, 节约操作时间的有益效果。
在本发明一实施例中,还可以通过水平偏移挂件图标实现挂件图标摆动的效果。 挂件呈现模块 200, 还适于当从指令接收模块 400接收到向下拉动并水平偏移 挂件图标的指令后, 将挂件图标向下移动, 延伸挂件图标上方的吊绳, 使挂件图标进 入拉伸状态, 固定吊绳顶端使挂件图标在水平方向摆动。
进一步地, 挂件呈现模块 200当挂件图标摆动到一侧极限位置时, 指示壁纸切 换模块 500 将桌面背景更改为切换前的壁纸图片, 当挂件图标摆动到另一侧极限位 置时, 指示所述壁纸切换模块 500将桌面背景更改为切换后的壁纸图片。
挂件呈现模块 200也可以当挂件图标摆动时, 指示所述壁纸切换模块 500将桌 面背景更改为当前背景切换前的壁纸图片, 或将桌面背景切换为新的壁纸图片。 例 如, 当挂件图标完成一个摆动周期后, 指示壁纸切换模块 500 将桌面背景更改为当 前背景切换前的壁纸图片。 由此, 只要没有接收到挂件图标停止摆动的指令, 便可 以对桌面背景进行持续恢复, 直到将桌面背景恢复到使用存储的壁纸图片前的原始 背景。 或者, 当挂件图标完成一个摆动周期后, 指示所述壁纸切换模块 500 将桌面 背景切换为新的壁纸图片。 由此, 在将挂件图标进行拉动并水平偏移后便可以实现 桌面背景的自动切换。
具体而言, 固定呈现的吊绳的顶点的 X轴和 Y轴坐标, 当挂件图标处于拉伸状 态且 X轴坐标产生位移时, 挂件图标呈钟摆运动。 并且可以当挂件图标摆动到一侧 极限位置时, 触发指示壁纸切换模块 500 将桌面背景更换回切换前的壁纸图片, 当 挂件图标摆动到另一侧极限位置时, 触发指示壁纸切换模块 500 将桌面背景更换为 切换后的壁纸图片。 或者, 在挂件图标摆动时指示壁纸切换模块 500 将桌面背景更 改为当前背景切换前的壁纸图片, 或将桌面背景切换为新的壁纸图片。
举例而言, 在挂件呈现模块 200通过挂件图片实现呈现挂件图标和吊绳时, 通 过转动挂件图片实现摆动挂件图标。 参见图 5, 示出了根据本发明一个实施例的通过 挂件图片摆动挂件图标的示意图。
挂件呈现模块 200根据指令中向下拉动的拉伸位移和水平偏移挂件图标的水平 位移确定摆动角度, 以呈现的吊绳顶端为中心, 按摆动角度转动挂件图片。 例如, 可以通过挂件图标的参考点的初始坐标和水平偏移后的坐标来得出摆动角度。 按该 摆动角度以呈现的吊绳顶端为中心转动挂件图片。
由此, 在本实施例中, 可以通过拉动挂件图标后水平偏移挂件图标来实现桌面 背景的自动切换或自动回复。
在本发明一实施例中, 挂件呈现模块 200通过挂件图片实现呈现挂件图标和吊 绳。 图片下载模块 100, 还适于接收服务器 1000下发的挂件图片, 指示挂件呈现模 块 200使用接收的挂件图片更新屏幕中呈现的挂件图标和挂件图标上方的吊绳。
挂件图片, 例如可以为一个 png图片, 通过服务器 1000对客户端 2000的挂件 的样式进行控制。 例如, 在节日到来时, 只要服务器 1000配置好, 各个客户端 2000 所在终端的桌面上的挂件就会随之改变, 如圣诞节到来时, 可以通过下发挂件图片 来将挂件图标切换成为圣诞祙或圣诞树, 在新年到来时, 可以通过下发挂件图片将 挂件图标切换成为红灯笼或者鞭炮。 当节日过去后, 可以将挂件图标在恢复到通常 样式。
由此, 能够对终端呈现的挂件样式进行统一管理和更新, 并可以丰富终端的挂 件样式。
参见图 6, 示意性地示出了根据本发明一个实施例的切换终端桌面背景的系统 的结构图。 系统包括服务器 1000和多个如前所述的客户端 2000。 服务器 1000, 适 于向客户端 2000下发壁纸图片。
进一步地, 服务器 1000还适于向客户端 2000下发挂件图片。
服务器 1000和客户端 2000间可以直接连接也可以通过网络连接, 在此没有特 別限制。
参见图 7, 示意性地示出了根据本发明一个实施例的切换终端桌面背景的方法 的流程图。 该方法包括如下步骤。
步骤 S710, 从服务器下载壁纸图片, 存储下载的壁纸图片, 在屏幕中呈现通常 状态下的挂件图标和位于挂件图标上方的吊绳。
所述在屏幕中呈现通常状态下的挂件图标和位于挂件图标上方的吊绳进一步包 括: 当下载的壁纸图片数量没有达到第一预设阀值时, 不呈现挂件图标和位于挂件 图标上方的吊绳; 当下载的壁纸图片数量达到第一预设阀值时, 在屏幕中呈现处于 通常状态的挂件图标和位于挂件图标上方的吊绳。 例如, 第一预设阀值为 5, 在下载的壁纸图片数量没有达到 5 时, 不呈现挂件 图标和位于挂件图标上方的吊绳, 当下载的壁纸图片数量达到 5 时, 在屏幕中呈现 处于通常状态的挂件图标和位于挂件图标上方的吊绳。
该方法还包括: 当存储的壁纸图片中未被提取过的壁纸图片的数量小于第二预 设阀值时, 从服务器下载第一预设数量的壁纸图片, 存储该下载的壁纸图片。
在本实施例中,在步骤 S730中提取存储的壁纸图片,将该壁纸图片设置为桌面 背景。 当存储的壁纸图片中未被提取过的壁纸图片的数量小于第二预设阀值时, 从 服务器下载第一预设数量的壁纸图片。 由此, 能够使得存储的壁纸图片中具有一定 数量的未被提取过的壁纸图片, 以保证在进行桌面背景切换时提取未被提取过的壁 纸图片。
例如, 第二预设阀值为 4, 第一预设数量为 5, 步骤 S710中将下载的壁纸图片 存储到壁纸图片队列中, 对壁纸图片队列中壁纸图片的提取进行记录, 当未被提取 过的壁纸图片的数量小于 4时, 自动从服务器下载 5 张的壁纸图片。 如果因为拉动 挂件过快, 导致从服务器下载新的壁纸图片的速度跟不上桌面背景切换速度, 在这 种情况下, 提取存储的已经提取过的壁纸图片进行桌面背景切换, 以保持挂件拉动 与桌面背景切换间的关联性, 进而保证 "下拉挂件-释放挂件 -背景切换" 的连贯性和 一致性。
通过上述预下载方式, 能够提高桌面背景的切换速度, 因为壁纸图片已经被下 载到客户端本地, 因此在挂件图标被下拉并释放后, 便可直接进行桌面背景切换, 不必再等待壁纸图片下载完成。
步骤 S720, 当接收到向下拉动屏幕中挂件图标的指令后, 依据指令中向下拉动 的拉伸位移将挂件图标向下移动, 并延伸挂件图标上方的吊绳, 直到挂件图标移动 到预设的下方极限位置或指令中向下拉动停止, 挂件图标进入拉伸状态。
步骤 S730, 当在挂件图标的拉伸状态下接收到释放挂件图标的指令后, 向上移 动挂件图标, 并收縮挂件图标上方的吊绳, 直到挂件图标上移到未被拉伸前的位置, 挂件图标恢复到通常状态, 并从存储的壁纸图片中提取一张壁纸图片, 将该壁纸图 片设置为桌面背景。
所述从存储的壁纸图片中提取一张壁纸图片进一步包括: 优先从存储的壁纸图 片中提取未被提取过的壁纸图片。
当没有未被提取过的壁纸图片时, 则提取存储的已经提取过的壁纸图片进行桌 面背景切换, 以保持挂件拉动与桌面背景切换间的关联性, 进而保证 "下拉挂件-释 放挂件 -背景切换" 的连贯性和一致性。
如图 2所示, 为根据本发明一个实施例的在通常状态下和拉伸状态下呈现的挂 件的示意图。 屏幕中呈现挂件图标 220和位于挂件图标上方的吊绳 210。 在通常状态下, 挂件图标中参考点的 Y轴坐标为 y0, 在预设的下方极限位置处 参考点的 Y轴坐标为 yl。
首先,在步骤 S720中接收到向下拉动屏幕中挂件图标的指令, 该指令可以为鼠 标向下拖拉挂件图标后触发的指令。 此时, 挂件图标从通常状态下, 图 2 中左边所 示的通常状态下, 随鼠标的向下拖拉而移动, 当挂件图标中参考点的坐标达到 yl或 鼠标停止拖拉时, 挂件图标不再沿 Y轴向下进行移动, 此时挂件图标进入拉伸状态, 如图 2右边所示。
然后,在步骤 S730中接收到释放挂件图标的指令,该指令可以为鼠标释放挂件 图标后触发的指令。 挂件图标开始向上移动, 并收縮挂件图标上方的吊绳, 当挂件 图标中参考点的坐标达到 y0时, 挂件图标上移到未被拉伸前的位置, 恢复到通常状 态, 即图 2中左边所示的状态。
举例而言, 可以通过挂件图片实现呈现挂件图标和吊绳。 该挂件图片中包含挂 件图标和位于挂件图标上方的吊绳。 此处仅为举例说明, 本发明对此没有特別限制, 也可以采用其他方式呈现挂件图标和吊绳。 例如, 可以根据指令对挂件图标和吊绳 进行重画, 以呈现挂件图标被下拉或释放的效果。
所述在屏幕中呈现通常状态下的挂件图标和位于挂件图标上方的吊绳进一步包 括: 设置不呈现挂件图片的不可见区域在屏幕中的位置, 将挂件图片中从顶部向下 预设长度的部分设置在不可见区域内, 在屏幕中呈现挂件图片。
如图 3所示,为根据本发明一个实施例的通过挂件图片呈现挂件图标的示意图。 在屏幕的最顶部之外设置不可见区域, 挂件图片在不可见区域的部分 310 不显示, 挂件图片的尺寸为 40px X 80px, 在通常状态下, 挂件图片从顶部向下 25px 的部分
310位于不可见区域内。 其中, 挂件图片的背景与屏幕中呈现挂件的区域处的背景相 同或者挂件图片的背景设置为透明, 采用挂件图片呈现挂件的效果如图 4所示。 图 4 中, 每組挂件中左侧为通常状态, 右侧为拉伸状态, 实际显示中, 每組中只显示一 个挂件, 该挂件如左侧所示, 处于通常状态, 或如右侧所示, 处于拉伸状态。
步骤 S 720中进一步包括接收到向下拉动屏幕中挂件图标的指令后,依据指令中 向下拉动的拉伸位移将挂件图片向下移动, 直到挂件图标移动到预设的下方极限位 置或指令中向下拉动停止。
步骤 S730中进一步包括当在拉伸状态下接收到释放挂件图标的指令后,向上移 动挂件图片到未被向下移动前的位置。 由此, 通过移动挂件图片实现挂件被拉伸和 收縮的效果。
由于挂件在屏幕中所占空间较小, 因此本实施例解决了在桌面背景切换后无法 及时获得切换后的桌面背景效果的技术问题, 又由于通过简单的拉动释放挂件便可 以实现桌面背景切换, 因此本实施例解决了切换终端桌面背景的操作复杂的技术问 题。 进而, 本实施例取得了在桌面背景切换后能够及时获得切换后的桌面背景效果 和切换终端桌面背景的操作简单易行, 节约操作时间的有益效果。
在本发明一实施例中,还可以通过水平偏移挂件图标实现挂件图标摆动的效果。 所述方法还包括: 当接收到向下拉动并水平偏移挂件图标的指令后, 将挂件图 标向下移动, 延伸挂件图标上方的吊绳, 使挂件图标进入拉伸状态, 固定吊绳顶端使 挂件图标在水平方向摆动。
进一步地, 所述方法还包括当挂件图标摆动到一侧极限位置时, 将桌面背景更 改为切换前的壁纸图片, 当挂件图标摆动到另一侧极限位置时, 将桌面背景更改为 切换后的壁纸图片。
所述方法也可以还包括: 当挂件图标摆动时, 将桌面背景更改为当前背景切换 前的壁纸图片, 或将桌面背景切换为新的壁纸图片。 例如, 当挂件图标完成一个摆 动周期后, 将桌面背景更改为当前背景切换前的壁纸图片。 由此, 只要没有接收到 挂件图标停止摆动的指令, 便可以对桌面背景进行持续恢复, 直到将桌面背景恢复 到使用存储的壁纸图片前的原始背景。 或者, 当挂件图标完成一个摆动周期后, 将 桌面背景切换为新的壁纸图片。 由此, 在将挂件图标进行拉动并水平偏移后便可以 实现桌面背景的自动切换。
具体而言, 固定呈现的吊绳的顶点的 X轴和 γ轴坐标, 当挂件图标处于拉伸状 态且 X轴坐标产生位移时, 挂件图标呈钟摆运动。 并且可以当挂件图标摆动到一侧 极限位置时, 触发桌面背景更换回切换前的壁纸图片, 当挂件图标摆动到另一侧极 限位置时, 触发桌面背景更换为切换后的壁纸图片。 或者, 当挂件图标摆动时将桌 面背景更改为当前背景切换前的壁纸图片, 或将桌面背景切换为新的壁纸图片。
举例而言, 在通过挂件图片实现呈现挂件图标和吊绳时, 通过转动挂件图片实 现摆动挂件图标。 参见图 5, 示出了根据本发明一个实施例的通过挂件图片摆动挂件 图标的示意图。
所述固定吊绳顶端使挂件图标在水平方向摆动进一步包括根据指令中向下拉动 的拉伸位移和水平偏移挂件图标的水平位移确定摆动角度, 以呈现的吊绳顶端为中 心, 按摆动角度转动挂件图片。 例如, 可以通过挂件图标的参考点的初始坐标和水 平偏移后的坐标来得出摆动角度。 按该摆动角度以呈现的吊绳顶端为中心转动挂件 图片。
由此, 在本实施例中, 可以通过拉动挂件图标后水平偏移挂件图标来实现桌面 背景的自动切换或自动回复。 在本发明一实施例中, 通过挂件图片实现呈现挂件图标和吊绳。 所述方法还包 括: 接收服务器下发的挂件图片, 使用接收的挂件图片更新屏幕中呈现的挂件图标 和挂件图标上方的吊绳。
挂件图片, 例如可以为一个 png图片, 通过服务器对客户端的挂件的样式进行 控制。 例如, 在节日到来时, 只要服务器配置好, 各个客户端所在终端的桌面上的 挂件就会随之改变, 如圣诞节到来时, 可以通过下发挂件图片来将挂件图标切换成 为圣诞祙或圣诞树, 在新年到来时, 可以通过下发挂件图片将挂件图标切换成为红 灯笼或者鞭炮。 当节日过去后, 可以将挂件图标在恢复到通常样式。
