android - 如何获取两点之间所有坐标的列表？

Question

我已经从这个Javascript 答案修改了这个答案。

他们有“空”，我用零代替。

但是，它有很多小故障。

public ArrayList<Point> getListOfIntermediatePoints(Point A, Point B ){
        float m = slope(A, B);
        int C = (int) intercept(A, m);

        ArrayList<Point> coordinates = new ArrayList<Point>(); 
        for (int i = A.x; i <= B.x; i++) {
            float j = m * i + C; //y = mx + c;
            coordinates.add(new Point(i,(int) j));
        }
        Log.d("coordinates", coordinates+"");
        return coordinates;
    }

    public float slope(Point a, Point b) {
        if (a.x == b.x) {
            return 0;
        }
        return (b.y - a.y) / (b.x - a.x);
    }

    float intercept(Point A, float slope) {
        if (slope == 0) {
            // vertical line
            return A.x;
        }
        return A.y - slope * A.x;
    }
