android如何旋转画布rect

我创建一个特定大小的矩形,现在我想将它旋转到45度,我使用canvas.rotate,矩阵,但不工作.如何在 android中旋转画布的正确方法？我对Path.Direction.CW感到好奇,是否用于旋转？但我没有在Path()中看到任何旋转功能

paint.setAntiAlias(true);
    paint.setstrokeWidth(2);
    paint.setColor(Color.BLUE);
    paint.setAlpha(75);

    Path path = new Path();
    path.addRect(166,748,314,890,Path.Direction.CW);
    canvas.rotate(45);
    canvas.drawPath(path,paint);

canvas.save();
canvas.rotate(45);
canvas.drawRect(166,paint);
canvas.restore();
