How to get the data on a specific Polyline

I want to show the Toast on a specific polyline coordinates, for example, in this code I want to show the Toast on that specific polyline, however, what happens is that onPolylineClick the Toast is showing the data that is last read by the program, in this case, the 'polylineClicker2()'.

The polyline is placed on its respective coordinates I have given, only the toast is doing what the program last read.

public void polylineClicker() {

        LatLng postition1  = new LatLng(14.601796, 121.006707);
        LatLng postition2  = new LatLng(14.601033, 120.998558);
        PolylineOptions popOption = new PolylineOptions()
                .add(postition1).add(postition2).width(5).color(Color.YELLOW).clickable(true);
        map.addPolyline(popOption);


        map.setOnPolylineClickListener(new GoogleMap.OnPolylineClickListener() {
            @Override
            public void onPolylineClick(Polyline polyline) {
                Toast.makeText(MainActivity.this, "Polyline near friends' house", Toast.LENGTH_SHORT).show();
            }
        });


    }
    public void polylineClicker2() {
        LatLng position1  = new LatLng(14.617106, 120.989924);
        LatLng position2  = new LatLng(14.616068, 120.990939);
        PolylineOptions popOption = new PolylineOptions()
                .add(position1).add(position2).width(5).color(Color.YELLOW).clickable(true);
        map.addPolyline(popOption);


        map.setOnPolylineClickListener(new GoogleMap.OnPolylineClickListener() {
            @Override
            public void onPolylineClick(Polyline polyline) {
                Toast.makeText(MainActivity.this, "Polyline near my house", Toast.LENGTH_SHORT).show();
            }
        });
    }

The GoogleMap.OnPolylineClickListener that you are setting on your polylineClicker2 is overriding the one that you are setting on your polylineClicker (assuming that you are calling polylineClicker before polylineClicker2).

You need to create just one GoogleMap.OnPolylineClickListener, and as you need different behavior (different messages) you can use tags. Using your code:

public void polylineClicker() {
    LatLng position1  = new LatLng(14.601796, 121.006707);
    LatLng position2  = new LatLng(14.601033, 120.998558);
    PolylineOptions popOption = new PolylineOptions()
            .add(position1).add(position2).width(5).color(Color.YELLOW).clickable(true);
    map.addPolyline(popOption).setTag("Polyline near friends' house");
}

public void polylineClicker2() {
    LatLng position1  = new LatLng(14.617106, 120.989924);
    LatLng position2  = new LatLng(14.616068, 120.990939);
    PolylineOptions popOption = new PolylineOptions()
            .add(position1).add(position2).width(5).color(Color.YELLOW).clickable(true);
    map.addPolyline(popOption).setTag("Polyline near my house");
}

And set the GoogleMap.OnPolylineClickListener wherever you need, for example on your onMapReady before calling polylineClicker and polylineClicker2:

map.setOnPolylineClickListener(new GoogleMap.OnPolylineClickListener() {
    @Override
    public void onPolylineClick(Polyline polyline) {
        Toast.makeText(MainActivity.this, (String) polyline.getTag(), Toast.LENGTH_SHORT).show();
    }
});
