Android Material Slider get value

Question

I'm trying to use the new Material Slider but I don't know if there is a way that I can get the value of the slider programmatically as a Integer.

I need the value as Integer because I have to work with the value doing some arithmetic calculations.

I get the value in float. How can I convert it to a Integer?

slider.addOnChangeListener(new Slider.OnChangeListener() {
    @Override
    public void onValueChange(@NonNull Slider slider, float value, boolean fromUser) {
        //Use the value
    }
});

You are given the value as a float... convert it into a int value that makes sense for your calculations — DevWithZachary, Sep 14 '21 at 10:36
I tried with a Toast message with (int)myvalue and it doesn't work — Giovanni, Sep 14 '21 at 10:39
The simplest way would be to cast it `int i = (int) value` but it will depend how you want to handle values, for example 1.999999 would be cast to 1 as an int — DevWithZachary, Sep 14 '21 at 10:40
what do you mean it doesn't work? be specific and provide error messages in your question — DevWithZachary, Sep 14 '21 at 10:40

Thanks, I just saw that I was forgotting to parse the result as String and not as a Float value. — Giovanni, Sep 15 '21 at 14:17

You have got the value of the slider. You have to convert it to a Integer. For converting float into integer, follow below code:

slider.addOnChangeListener(new Slider.OnChangeListener() {
    @Override
    public void onValueChange(@NonNull Slider slider, float value, boolean fromUser) {
        Integer slide_value = Math.round(value); 
    }
});

NOTE: Using Math.round() will round the float to the nearest integer.
