我正在尝试在我的应用中的地图视图上绘制填充多边形。无论我尝试过什么,它都不会被填满。我可以让笔画出现,但我无法填写。下面是我的多边形类的绘制方法。它会覆盖叠加层。
public void draw(Canvas canvas, MapView mapv, boolean shadow) {
super.draw(canvas, mapv, shadow);
Paint mPaint = new Paint();
mPaint.setStyle(Paint.Style.STROKE);
mPaint.setColor(Color.BLACK);
mPaint.setStrokeJoin(Paint.Join.ROUND);
mPaint.setStrokeCap(Paint.Cap.ROUND);
mPaint.setStrokeWidth(6);
Paint mPaintFill = new Paint();
mPaintFill.setStyle(Paint.Style.FILL);
mPaintFill.setColor(Color.GREEN);
Path path = new Path();
GeoPoint start = route.get(0);
for (int i = 1; i < route.size(); ++i) {
Point p1 = new Point();
Point p2 = new Point();
Projection projection = mapv.getProjection();
projection.toPixels(start, p1);
projection.toPixels(route.get(i), p2);
path.moveTo(p2.x, p2.y);
path.lineTo(p1.x, p1.y);
start = route.get(i);
}
canvas.drawPath(path, mPaint);
canvas.drawPath(path, mPaintFill);
//canvas.clipPath(path, Op.DIFFERENCE);
}
上面的代码对我来说会正确绘制线条但是没有填写。删除canvas.drawPath(path,mPaint);而只是离开填充一个导致地图上没有任何显示。我甚至尝试将Paint.Style.STROKE设置为Paint.Style.FILL_AND_STROKE。我完全失去了,在这一点上,我认为这是一个简单的事情,我一直在寻找。
