其中，圆角矩形在电子设备中被大量使用，比如，采用圆角矩形制作图标、弹窗或选项框等。在本申请提供的各实施例中所述的圆角控件，包括但不限于为圆角矩形，然而，由于圆角矩形作为其中一种最为典型的圆角控件，因此，在以下的实施例中，以圆角矩形为例，详细说明圆角矩形中左上角的圆角曲线的绘制过程。
应该说明的是，本申请各实施例提供的圆角曲线绘制方法，应用于电子设备，其中，所述电子设备主要是指配置为安卓系统的电子设备，所述电子设备包括但不限是智能终端、平板本电脑、PDA(Personal Digital Assistant，个人数字助理)、电子书阅读器、多媒体播放器等。
具体的，请参阅图2a，本申请实施例提供一种圆角曲线绘制方法，所述方法包括：
S21、获取圆角控件的绘制参数；
其中，所述圆角控件中包含有至少一条圆角曲线，以及与所述圆角曲线连接的第一直边和第二直边。具体的，圆角曲线是指一段分别与第一直边和第二直边相切的圆弧曲线，将该圆弧曲线用以替换原来由第一直边和第二直边形成的角，从而构成所述控件的圆角，并将至少包含一个上述圆角曲线的控件成为圆角控件。
绘制参数是指绘制圆角曲线所必须提供的参数，其中，所述绘制参数中至少包括所述圆角曲线的圆角半径。
可以理解的，圆角半径的大小体现了圆角曲线的弯曲程度，半径越大，所述圆角曲线的弯曲程度越低；相反的，半径越小，所述圆角曲线的弯曲程度越高。
因此，为了保证圆角曲线的弯曲程度，在一些实施例中，所述绘制参数还包括所述圆角控件的宽和高，在获取圆角控件的绘制参数后，请参阅图2b，所述方法还包括：
S211、确定所述圆角曲线的宽或所述圆角曲线的高是否小于所述圆角半径；
S212、若是，则将预存的圆角半径阈值设置为所述圆角半径。
其中，预存的圆角半径阈值的取值为140px。
S22、根据所述圆角半径获取N个曲率半径，其中，N为大于0的自然数；
S23、根据所述绘制参数以及N个所述曲率半径，绘制M条贝塞尔曲线，其中，M为大于0的自然数,N为M的倍数；
应该说明的是，在现有技术中，将圆的一段圆弧曲线相切在第一直边和第二直边，以构成所述圆角控件的圆角。可以理解的，该圆弧曲线上任意一点的曲率半径即为该圆的半径。然而，通过上述方法绘制的圆弧曲线， 容易出现所述圆弧曲线的过渡不够圆滑而出现梯度的情况。
因此，在本申请实施例中，引入贝塞尔曲线来以替代现有技术中的圆弧曲线，以改善圆弧曲线的过渡不够圆滑的问题。
贝塞尔曲线，又称为贝茨曲线，是应用于二维图形应用程序的数学曲线。其中，所述贝塞尔曲线由起始点、终止点及控制点组成，可通过调整控制点改变所述贝塞尔曲线的形状。
在所述电子设备配置的系统中，预先定义了用于绘制控件的应用程序接口函数(Application Programming Interface，API)。可以理解的，Canvas用于绘制常规图形，例如，用于绘制圆、椭圆或矩形等常规图形，若需要绘制更复杂的图形，例如，绘制圆角矩形，则需结合Path路径才能完成。于是，当触发绘制圆角控件时，所述电子设备根据绘制参数创建所述圆角曲线的路径，并将所述路径代入Canvas的DrawPath方法中，以在Canvas上绘制所述圆角控件的圆角曲线。
在具体创建所述圆角曲线的路径时，由于所述圆角曲线由M条贝塞尔曲线构成，因此，根据圆角半径获取出N个曲率半径，并结合所述圆角控件的绘制参数分别计算出M条贝塞尔曲线的起始点、终止点及控制点坐标，从而创建出所述圆角曲线的绘制路径。
在一些实施例中，所述贝塞尔曲线为二阶贝塞尔曲线；当所述贝塞尔曲线为二阶贝塞尔曲线时，N具体取值为18，M具体取值为6。
在又一些实施例中，根据所述圆角半径和高斯概率分布获取N个所述曲率半径。
其中，高斯分布又称为正态分布，其分布曲线呈钟形，反映了随机变量的分布规律，用于计算随机变量落入任何范围内的概率。其中，标准差σ的取值决定了概率分布的幅度。在本申请实施例中，引入高斯概率分布函数用以获取出N个曲率半径，具体的，随机数y分布在区间(-jσ,+jσ)的高 斯概率分布函数为：
其中，j为大于等于0且小于N的整数，在具体取值时，从j＝N-1开始，依次向下递减，直至j＝0，从而得到N个概率密度值。
进而，将所述圆角半径依次与N个概率密度值进行乘积计算，从而得到N个曲率半径。
应该说明的是，当j＝N-1时，其概率密度值趋近于1；当j＝0，其概率密度值等于0。
在又一些实施例中，可以通过定义所述高斯概率分布的标准差σ的值，以得到不同幅值的分布曲线，从而改变了N个曲率半径的取值，进而改变绘制的贝塞尔曲线的形状。
在本实施例中，通过自定义高斯概率分布曲线，以获取到不同幅值的分布曲线下的概率密度值，进而绘制出不同曲率的贝塞尔曲线。
S24、依次连接M条所述贝塞尔曲线，以形成目标圆角曲线。
在绘制出M条贝塞尔曲线后，依次将第i条所述贝塞尔曲线的终止点与第i+1条所述贝塞尔曲线的起始点进行连接，以形成目标圆角曲线，其中i为大于0的自然数。
在本申请实施例中，提供一种圆角曲线绘制方法，通过将圆角控件中的圆角曲线分为M段贝塞尔曲线进行分段绘制，并依次连接M段贝塞尔曲线得到的目标圆角曲线，从而提高了目标圆角曲线的平滑度。
其中，所述目标圆角曲线分别与所述第一直边和所述第二直边相切，为了使所述目标圆角曲线与所述第一直边、所述第二直边进行较好的过渡，请参阅图3a，所述绘制参数还包括所述第一直边的位置坐标和所述第二直边的位置坐标，所述根据所述绘制参数以及N个所述曲率半径，绘制M条贝塞尔曲线，包括：
S31、根据所述第一直边的位置坐标、所述第二直边的位置坐标、所述圆角控件的高及N个所述曲率半径，获取所述贝塞尔曲线的起始点坐标、控制点坐标以及终止点坐标；
具体的，以绘制圆角矩形左上角的圆角曲线为例进行说明，请参阅图3b，需要说明是，在Canvas的坐标系XOY中，Canvas坐标系有且只有一个，且是唯一不变的，其坐标原点在View的左上角，从坐标原点向右为X轴的正半轴，从坐标原点向下为Y轴的正半轴。所述第一直边相对于坐标系的Y轴平行，所述第二直边相对于坐标系的X轴平行。因此，所述第一直边的位置坐标是指第一直边投影在X轴的坐标x
1，所述第二直边的位置坐标是指第二直边投影在Y轴的坐标y
2。
于是，根据下述公式计算所述贝塞尔曲线的起始点坐标、控制点坐标及终止点坐标：
其中，
为起始点的横坐标，
起始点的纵坐标，
为控制点的横坐标，
控制点的纵坐标，
为终止点的横坐标，
为终止点的纵坐标，R为圆角半径，x
1为第一直边的横坐标，y
2为第二直边的纵坐标，Height为圆角控件的高，r
i为第i个曲率半径，i为大于0的自然数。
S32、将所述起始点坐标、所述控制点坐标及所述终止点坐标代入所述贝塞尔曲线的绘制函数，以依次绘制出对应的贝塞尔曲线。
需要说明的是，Canvas的DrawPath方法中传入的各种坐标指的都是绘图坐标系中的坐标，而非Canvas坐标系中的坐标。默认情况下，绘图坐标系与Canvas坐标系完全重合。
可以理解的是，当需要将所述圆角矩形的其他角绘制成圆角时，只需 将上述计算所述贝塞尔曲线的起始点坐标、控制点坐标及终止点坐标的公式中的第一直边和第二直边的坐标替换为与当前绘制圆角曲线相切的两条直边即可。
在本申请实施例中，通过分别确定各段贝塞尔曲线的起始点坐标、控制点坐标及终止点坐标，从而根据起始点坐标、控制点坐标及终止点坐标唯一绘制出对应的贝塞尔曲线。
可以理解的，所述圆角控件中至少包含有一条圆角曲线，以及与所述圆角曲线连接的第一直边和第二直边，因此，在绘制出目标圆角曲线后，请参阅图4，所述方法还包括：
S41、确定所述目标圆角曲线在所述第一直边的绘制起点的纵坐标；
其中，所述绘制起点的纵坐标为：
Y
起：Width/2-R；
其中，Y
起为所述目标圆角曲线的绘制起点的纵坐标，Width为圆角控件的宽，R为圆角曲线的圆角半径。
S42、依次将所述绘制起点、所述目标圆角曲线及所述第二直边顺序连接。
可以理解的，所述绘制起点为所述目标圆角曲线在所述第一直边的切点，将所述目标圆角曲线与所述第一直边在所述绘制起点连接，使得所述目标圆角曲线与第一直边、第二直边的衔接能够平滑过渡，进而保证了所述圆角控件的顺滑效果，提高了用户体验。
