Research direction
Start with the custom View drawing code represented by the snippet, especially the Path.setFillType and canvas.drawPath calls. Reproduce the example with EVEN_ODD and INVERSE_EVEN_ODD, then compare the rendered result against Android's Path.FillType documentation; done means the observed behavior is explained or a confirmed Android issue is documented.
Written by the indexing model from the issue text.
Description
mPaint.setStyle(Paint.Style.FILL);
canvas.translate(mWidth / 2, mHeight / 2);
Path path = new Path();
path.addRect(-200,-200,200,200, Path.Direction.CW);
//path.setFillType(Path.FillType.EVEN_ODD)；
path.setFillType(Path.FillType.INVERSE_EVEN_ODD); // 反奇偶规则
canvas.drawPath(path, mPaint);
效果跟使用Path.FillType.EVEN_ODD的效果一样，应该相反的。不知道怎么回事。。
