            val rangeSlider: RangeSlider = findViewById(R.id.rangeSlider);
            val textView: TextView = findViewById(R.id.textView);
            val textView2: TextView = findViewById(R.id.textView2);

            rangeSlider.addOnSliderTouchListener(object : RangeSlider.OnSliderTouchListener{

                    val values = rangeSlider.values
                    //Those are the satrt and end values of sldier when user start dragging
                    Log.i("SliderPreviousValue From", values[0].toString())

                    Log.i("SliderNewValue From", values[0].toString())
                    Log.i("SliderNewValue To", values[1].toString())
    
                    textView.setText("Start value: ${values[0]}, End value: ${values[1]}")
                }
            })
    
    
            //If you only want the slider start and end value and don't care about the previous values
            rangeSlider.addOnChangeListener { slider, value, fromUser ->
                val values = rangeSlider.values
                textView2.text = "Start value: ${values[0]}, End value: ${values[1]}";
