移动图形Path对象

Question

特别是在Java,Android中,如何将Path对象转换为100个像素？就像在C#中一样,我会使用以下代码来执行此操作:

// Create a path and add and ellipse.
GraphicsPath myPath = new GraphicsPath();
myPath.AddEllipse(0, 0, 100, 200);

// Draw the starting position to screen.
e.Graphics.DrawPath(Pens.Black, myPath);

// Move the ellipse 100 points to the right.
Matrix translateMatrix = new Matrix();
translateMatrix.Translate(100, 0);
myPath.Transform(translateMatrix);

// Draw the transformed ellipse to the screen.
e.Graphics.DrawPath(new Pen(Color.Red, 2), myPath);

我如何在Android中执行此操作？我已经有了Path对象:

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    Paint pnt = new Paint();
    Path p = new Path();    

    pnt.setStyle(Paint.Style.STROKE);
    pnt.setColor(Color.WHITE);

    p.moveTo(97.4f, 87.6f);
    p.lineTo(97.4f, 3.8f);

    p.lineTo(-1.2f, 1.2f);
    p.lineTo(-0.4f,-0.4f);

    p.lineTo(-0.4f,87f);

    p.lineTo(97.4f, 87.6f);
    p.close();          

    canvas.drawPath(p, pnt);            
}

为了将Path对象移动超过100个像素,我需要做什么？

Answer 1

它几乎是一样的:

Matrix translateMatrix = new Matrix();
translateMatrix.setTranslate(100,0);
p.transform(translateMatrix);

我没有测试它,只是看了API.

Answer 2

我认为Path.offset(float dx, float dy)这就是你要找的东西.
