[C++] 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
 2    double d = (double) (Math.PI / 30);
 3    double[] angle = new double[61];//设置角度差
 4    for (int i = 0; i < 61; i++) {
5      angle[i] = i * d;
6    }
7//建立一个角度差double数组
8    double[] ox = new double[61];
9    for (int i = 0; i < 61; i++) {
10      ox[i] = r * (2 * Math.cos(angle[i]) - Math.cos(2 * angle[i]));
11    }
12//计算x坐标
13    double[] oy = new double[61];
14    for (int i = 0; i < 61; i++) {
15      oy[i] = r * (2 * Math.sin(angle[i]) - Math.sin(2 * angle[i]));
16    }
17//计算y坐标
18    Point[] heart = new Point[61];
19    for (int i = 0; i < 61; i++) {
20      heart[i] = new Point();
21      heart[i].x = (int) oy[i] + x;
22      heart[i].y = -(int) ox[i] + y;
23    }
24//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
25    getUiDevice().swipe(heart, 2);
