You can define a common method to draw polygon on google maps like this:
public PolygonOptions addPolygon(ArrayList < LatLng > arg) {
LatLng[] data = arg.toArray();
PolygonOptions polygonOptions;
for (int i = 0; i <= data.length; i++) {
polygonOptions = new PolygonOptions();
polygonOptions.add(data[i], data[i + 1], data[i + 2])).strokeColor(Color.RED).strokeWidth(2);
polygonOptions.fillColor(Color.parseColor("#51000000"));
return polygonOptions;
}
}
and then add it to your GoogleMap like this:
yourGoogleMap.addPolygon(addPolygon(data));

i am faced another problem when i make polygon clockwise its fine but when its clock+anticlockwise( Both Direction ) then stroke line will appear on fill color and the drawing spoiled

you need to show some of your code at least otherwise it will be very painful for me to understand.@vikas

for (int j = 0; j < maindata.size(); j++) { lines = new PolygonOptions(); Log.i("main", "maindata values " + maindata.get(j)); data = maindata.get(j); for (int i = 0; i < data.size(); i++) { lines.add(data.get(i)); lines.strokeWidth(3); lines.strokeColor(Color.TRANSPARENT); lines.fillColor(Color.parseColor("#51000000")); googlemap.addPolygon(lines); } } maindata.clear(); data.clear();
