Question

Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.

Or is it just better to manually write the current finger position to an array?

thanks

Answer 1

You can read as many points as you want from any path.
Example how to read coordinates from the middle of path:

    PathMeasure pm = new PathMeasure(myPath, false);
    //coordinates will be here
    float aCoordinates[] = {0f, 0f};

    //get coordinates of the middle point
    pm.getPosTan(pm.getLength() * 0.5f, aCoordinates, null);

You can pass any distance from the path start to get point coordinates.
