How to draw a line in LibGDX without ShapeRenderer

Question

I am using LibGDX and have an ArrayList of multiple points which I want to connect. I am aware there are several methods with ShapeRenderer that work, however im running a SpriteBatch at the same time so what do I do now to draw a line with two Vectors. (If it exists, I'd also like the function that draws multiple lines at once with an Àrray or Vector2 as a parameter, though it isn't a problem as otherwise I'd manage with a for-loop probably).

I am also aware I can use Pixmaps but they don't seem to work correctly. Here is my attempt:

// point1 and point2 are of type Vector2
Pixmap pixmap = new Pixmap(point2.x - point1.x, 2, Pixmap.Format.RGBA8888);
pixmap.setColor(Color.WHITE);
pixmap.drawLine(point1.x, point1.y, point2.x, point2.y);

In response to a possible solution that involves using ShapeRenderer at the same time, this problem arises (the second image uses the points with pixmaps, the first the ShapeRenderer with lines)

The code used for the first image is the following:

        for(int i = 1; i < dotPositions.size(); i++) {
            sr.line(dotPositions.get(i-1), dotPositions.get(i));
        }

The code used for the second image is the following:

        Pixmap pixmap = new Pixmap(2, 2, Pixmap.Format.RGBA8888);
        pixmap.setColor(Color.WHITE);
        pixmap.fillCircle(2, 2, 2);
        Texture texture = new Texture(pixmap);

        for(int i = 1; i < dotPositions.size(); i++) {
            batch.draw(texture, dotPositions.get(i).x, dotPositions.get(i).y);
        }

In both cases dotPositions is an ArrayList<Vector2> with the same values.

If anyone in the future may be interested, I found the solution and all I had to do was use ShapeRender.setProjectionMatrix(cam.combined) to sync it with the SpriteBatch.
