android uiautomator一个画心形图案的方法--代码的浪漫

    public void heart(int x, int y, int r) {//画心形的方法
        double d = (double) (Math.PI / 30);
        double[] angle = new double[61];//设置角度差
        for (int i = 0; i < 61; i++) {
            angle[i] = i * d;
        }
//建立一个角度差double数组
        double[] ox = new double[61];
        for (int i = 0; i < 61; i++) {
            ox[i] = r * (2 * Math.cos(angle[i]) - Math.cos(2 * angle[i]));
        }
//计算x坐标
        double[] oy = new double[61];
        for (int i = 0; i < 61; i++) {
            oy[i] = r * (2 * Math.sin(angle[i]) - Math.sin(2 * angle[i]));
        }
//计算y坐标
        Point[] heart = new Point[61];
        for (int i = 0; i < 61; i++) {
            heart[i] = new Point();
            heart[i].x = (int) oy[i] + x;
            heart[i].y = -(int) ox[i] + y;
        }
//简历一个点数组，这里坐标一定要转化一下，不然是倒着的心形
        getUiDevice().swipe(heart, 2);
