Google Maps user-editable polygon with fixed number of points in Android?

Question

I am working on Google Map polygon marker, I have predefined lat/long array, and need to set polygon area, It is working fine for me, but when I drag the marker polygon line

Answer 1

I think you're using the tools you have a little inefficiently. My recommendation would be to store an array of markers, and use markerTag to store the index of your point, so in drawPolygon

for (int i = 0; i < coordinates.size(); i++) {
   markers[i].setTag(i); //Associate a marker with a point
}

Then, when you move the marker, you would replace the co-ordinate at that point like so:

points[marker.getTag().toInt()] = marker.getTag().getPosition();

Sorry this is so vague. I use kotlin, so I've probably gotten some of the syntax wrong, too.
