如何使用“ Path myPath = new Path（）;”
您将在其中指定x和y位置以使用线并填充来创建三角形。您可以阅读有关内容，这是我从某处获取的示例。
// create and draw triangles// use a Path object to store the 3 line segments// use .offset to draw in many locations// note: this triangle is not centered at 0,0paint.setStyle(Paint.Style.STROKE);paint.setStrokeWidth(2);paint.setColor(Color.RED);Path path = new Path();path.moveTo(0, -10);path.lineTo(5, 0);path.lineTo(-5, 0);path.close();path.offset(10, 40);canvas.drawPath(path, paint);path.offset(50, 100);canvas.drawPath(path, paint);// offset is cumlative// next draw displaces 50,100 from previouspath.offset(50, 100);canvas.drawPath(path, paint);
