所以我用下面的code在我的画法绘制这个三角形在Android地图：

So I'm drawing this triangle in android maps using the code below in my draw method:

paint.setARGB(255, 153, 29, 29);
paint.setStyle(Paint.Style.FILL_AND_STROKE);
paint.setAntiAlias(true);

Path path = new Path();
path.moveTo(point1_returned.x, point1_returned.y);
path.lineTo(point2_returned.x, point2_returned.y);
path.moveTo(point2_returned.x, point2_returned.y);
path.lineTo(point3_returned.x, point3_returned.y);
path.moveTo(point3_returned.x, point3_returned.y);
path.lineTo(point1_returned.x, point1_returned.y);
path.close();

canvas.drawPath(path, paint);

该pointX_returned是其中我从田野得到的坐标。他们基本上是经度和纬度。 其结果是一个很好的三角形，但内幕是空的，所以我可以看到地图。有没有办法以某种方式填补它？

The pointX_returned are the coordinates which I'm getting from the fields. They are basically latitudes and longitudes. The result is a nice triangle but the insider is empty and therefore I can see the map. Is there a way to fill it up somehow?

推荐答案

您可能需要做一些事情，如：

You probably need to do something like :

Paint red = new Paint();

red.setColor(android.graphics.Color.RED);
red.setStyle(Paint.Style.FILL);

和使用，而不是你的ARGB这个颜色你的路径。确保在第一个路径中的最后一个点结束，这是有道理的也。

And use this color for your path, instead of your ARGB. Make sure the last point of your path ends on the first one, it makes sense also.

告诉我，如果它的工作原理，请！
