安装教程

1.在项目根目录下的build.gradle文件中,

allprojects {
   repositories {
       maven {
           url 'https://s01.oss.sonatype.org/content/repositories/releases/'
       }
   }
}

2.在entry模块的build.gradle文件中,

dependencies {
   implementation('com.gitee.chinasoft_ohos:polygondrawingutil:1.0.0')
   ......  
}

在sdk6,DevEco Studio2.2 Beta1下项目可直接运行 如无法运行,删除项目.gradle,.idea,build,gradle,build.gradle文件, 并依据自己的版本创建新项目,将新项目的对应文件复制到根目录下

使用说明

参数:
1.sideCount 可指定边数(≥3)
2.centerX center 可指定中心坐标
3.outerRadius 可指定外半径(中心到顶点)
4.cornerRadius 可指定圆角倒圆半径
5.rotation 可指定多边形旋转
6.Paint 可选填充/描边Paint
7.Path 可选目标Path实例

使用:
1.创建一个新的“ PolygonDrawingUtil”实例,并将其分配给您的自定义视图类中的一个属性:

PolygonDrawingUtil polygonDrawingUtil = new PolygonDrawingUtil();

2.使用 polygonDrawUtil.drawPolygononDraw 方法中:

@Override
public void onDraw(Component component, Canvas canvas) {
    Float centerX = (component.getWidth() / 2f);
    Float centerY = (component.getHeight() / 2f);
    Float radius = scale * (component.getWidth() / 2f - strokeWidth);
    // Method 1 (simpler for direct drawing):
    polygonDrawingUtil.drawPolygon(
            canvas,
            this.numberOfSides,
            centerX,
            centerY,
            radius,
            cornerRadius,
            polygonRotation,
            polygonFillPaint
    );
}

或者,您可以提供自己的Path实例,并要求PolygonDrawingUtil用多边形填充它 :

Path strokePath = new Patch();
......

polygonDrawingUtil.constructPolygonPath(
        strokePath,
        this.numberOfSides,
        centerX,
        centerY,
        radius,
        cornerRadius,
        polygonRotation
);

这使您可以在绘制到“Canvas”之前在“Path”上执行后处理。
