二阶

三阶

看着图真的很好理解，公式就不展开了，Android有现成的api

二阶绘制实例

public MyView(Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);

    paint.setColor(Color.YELLOW);
}

private Paint paint = new Paint();

private Path path = new Path();
private int beginX;
private int beginY;
private int supX = 100;
private int supY = 100;
private int endX = 300;
private int endY = 0;

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    path.moveTo(beginX, beginY);
    path.quadTo(supX, supY, endX, endY);

    canvas.drawPath(path, paint);
}
