Creating a path for animation given a set of coordinate points in Android Studio

Question

I asked this question before, but now I've stumbled around and figured out a direction. Basically, I need to record the user's finger's movements around the screen, and replay an animation of that movement on a view upon pressing a replay button, as well as a reverse animation of it when pressing a reverse button. I'm trying to achieve this by saving the finger's (x,y) coordinates in onTouch(), which I store in an ArrayList for PointF objects, then create a path for the view to animate on based on the coordinates stored in said ArrayList. Then I'll need to animate along that path. However, I am not sure how to create a path based on an arraylist that could be of any length.

Code related to the animation so far:

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;

public class MyView extends View {
    ArrayList<PointF>theCoords;
    ArrayList<Float> xcord;
    ArrayList<Float> ycord;
    private Paint paint;
    //coordinates
    private float x;
    private float y;


    public MyView (Context context, AttributeSet attrs) {
        super(context, attrs);
        initPaint();
        xcord = new ArrayList<Float>();
        ycord= new ArrayList<Float>();
        theCoords=new ArrayList<PointF>();
    }


    public MyView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        initPaint();
