具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种基于安卓系统的曲线绘制处理方法，图1是根据本发明实施例的基于安卓系统的曲线绘制处理方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，接收在设备屏幕输入的第一点的第一坐标；
步骤S104，检测到在设备屏幕输入的第二点的第二坐标；
步骤S106，判断第一点与第二点之间的距离是否超过预定阈值，其中，该预定阈值可以依据具体设备而定，例如，该预定阈值可以为5个单位；
步骤S108，在判断结果为是的情况下，基于第一点的第一坐标和第二点的第二坐标绘制曲线。
通过上述步骤，依据点与点之间的距离是否超过预定距离来决定是否在点与点之间绘制曲线，相对于相关技术中，对设备屏幕上检测到的每个点均进行绘制，导致存在效率低下的问题，采用该方法通过有效地控制了绘图所采用的点，不仅提高了绘图效率，而且在一定程度上间接地实现了绘制曲线的平滑度。
在判断第一点与第二点之间的距离是否超过预定阈值时，可以采用多种方式，例如，可以直接依据点与点的坐标之间的差别来判断：判断第一点的横坐标与第二点的横坐标之差是否超过横坐标预定阈值，以及第一点的纵坐标与第二点的纵坐标之差是否超过纵坐标预定阈值；在上述判断结果均为是的情况下，确定第一点与第二点之间的距离超过预定阈值，其中，该预定阈值包括横坐标预定阈值和纵坐标预定阈值。又例如，判断第一点与第二点之间的距离是否超过预定阈值还可以采用以下处理：依据第一坐标和第二坐标，获取第一点与第二点之间的直线距离；之后，判断直线距离是否超过预定阈值；在判断结果为是的情况下，确定第一点与第二点之间的距离超过预定阈值。需要说明的是，上述判断第一点与第二点之间的距离是否超过预定阈值可以依据具体情况而选择。
较佳地，在基于第一点的第一坐标和第二点的第二坐标绘制曲线之后，还包括：对设备屏幕进行刷新，使得绘图的进程明显，清晰。
在本实施例中还提供了一种基于安卓系统的曲线绘制处理装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图2是根据本发明实施例的基于安卓系统的曲线绘制处理装置的结构框图，如图2所示，该装置包括接收模块22、检测模块24、判断模块26和绘制模块28，下面对该装置进行说明。
接收模块22，设置为接收在设备屏幕输入的第一点的第一坐标；检测模块24，连接至上述接收模块22，设置为检测到在设备屏幕输入的第二点的第二坐标；判断模块26，连接至上述检测模块24，设置为判断第一点与第二点之间的距离是否超过预定阈值；绘制模块28，连接至上述判断模块26，设置为在判断模块的判断结果为是的情况下，基于第一点的第一坐标和第二点的第二坐标绘制曲线。

第一判断单元32，设置为判断第一点的横坐标与第二点的横坐标之差是否超过横坐标预定阈值，以及第一点的纵坐标与第二点的纵坐标之差是否超过纵坐标预定阈值；第一确定单元34，连接至上述第一判断单元32，设置为在第一判断单元的判断结果为 是的情况下，确定第一点与第二点之间的距离超过预定阈值，其中，预定阈值包括横坐标预定阈值和纵坐标预定阈值。
图4是根据本发明实施例的基于安卓系统的曲线绘制处理装置中判断模块26的优选结构框图二，如图4所示，该判断模块26包括获取单元42、第二判断单元44和第二确定单元46，下面对该判断模块26进行说明。
获取单元42，设置为依据第一坐标和第二坐标，获取第一点与第二点之间的直线距离；第二判断单元44，连接至上述获取单元42，设置为判断直线距离是否超过预定阈值；第二确定单元46，连接至上述第二判断单元44，设置为在第二判断单元44的判断结果为是的情况下，确定第一点与第二点之间的距离超过预定阈值。
图5是根据本发明实施例的基于安卓系统的曲线绘制处理装置的优选结构框图，如图5所示，该装置除包括图2所示的所有模块外，还包括刷新模块52，下面对该刷新模块52进行说明。
刷新模块52，连接至上述绘制模块28，设置为对设备屏幕进行刷新。
图6是根据本发明实施例的终端的结构框图，如图6所示，该终端60包括上述任一项的曲线绘制处理装置62。
针对相关技术中画图效率低的问题，在本实施例中，提供了一种基于Android画图框架的绘画方案，该方案主要采用以下处理：将用户手指输入的前一次坐标位置和当前的坐标位置进行比较，如果小于某一个经验值就不进行绘制当前点，否则就绘制当前点和前一个点之间的曲线，并进行刷新绘画。这样循环往复的进行绘制，使得手指移动过的坐标位置并不是将每一次的坐标都进行绘制，达到了提高绘制效率的目的。特别地，对于Android低端设备，在提高用户实时绘制曲线的效率和平滑度上效果更为明显。
该方案可以包括以下处理步骤：
S1，记录第一次手指触摸屏幕的坐标值；
S2，记录每次手指移动的坐标值，将本次坐标值与前一次坐标值进行x轴和y轴方向的差值判断；
S3，如果差值小于某个经验值，则忽略本次坐标值，继续获取下一个手指移动的坐标值，重复步骤S2；
S4，如果差值大于某个经验值，则绘制前一次坐标值到本次坐标值之间的曲线；
S5，从步骤S2开始重复执行。
下面对本发明优选实施例进行说明。
图7是根据本发明优选实施方式的绘画方案示意图，如图7所示，p1和p2是绘制过程中的两个点，该绘画方案包括如下处理：
S1，手指按住屏幕不动，记录第一个点的坐标值p1(x1,y1)；
S2，此时移动手指，Android系统检测到手指移动的第二个点，并记录第二个点的坐标值p2(x2,y2)，分别计算这两个坐标点的x轴差值和y轴差值，得出x轴差值Δx和y轴差值Δy；
S3，如果Δx小于某个经验值(例如，第一经验值)并且Δy小于某个经验值(例如，第二经验值)，则忽略本次坐标值，继续获取下一个点的坐标值，重复步骤S2；
S4，如果Δx大于某个经验值并且Δy大于某个经验值，则通过调用Android系统绘制曲线的方法quadTo()函数绘制这两个点之间的曲线；
S5，从步骤S2开始重复执行。
需要说明的是，上述经验值的取值，可以通过不断的数据筛选得到，从而选出一个适当的值，以达到绘制效率较高、绘制的曲线较平滑的效果。例如，在本实施例中，较优地，可以在应用-电子白板中该经验值取值为5，该值能使得绘制的曲线比较平滑并且在低端的设备上绘制比较流畅。
另外，上述仅以手机设备为例进行了说明，但使用的设备不局限于手机，只要是以Android为操作系统的终端设备都可以，比如，还可以是Android系统的PAD等。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
