Define step value increment for custom RangeSeekBar

Versions

[{“Name”:“1.0”,“GroupName”:null}]

Introduction

A customization of the Android RangeSeekBar proposed by Alex Florescu at https://github.com/anothem/android-range-seek-bar

It allows to define a step value (increment), when moving the seek bar

Remarks

1- Add the increment attribute in attrs.xml

<attr name="increment" format="integer|float"/>

2- Define a default value in RangeSeekBar.java and create the attribute also

private static final int DEFAULT_INCREMENT = 1;
private int increment;

3- Init the increment value in private void init(Context context, AttributeSet attrs)

if (attrs == null) 
    increment = DEFAULT_INCREMENT;
else 
    increment = a.getInt(R.styleable.RangeSeekBar_increment, DEFAULT_INCREMENT);

4- Define the increment value in protected synchronized void onDraw(@NonNull Canvas canvas)

You’ll have to replace the minText and maxText value. So instead of :

You’ll have :

int x;

x = (int) ((getSelectedMinValue().intValue()+increment)/increment);
x = x*increment;
if (x<absoluteMaxValue.intValue()) 
    minText = ""+x;
else
    minText=""+(absoluteMaxValue.intValue()-increment);

x = (int) ((getSelectedMaxValue().intValue()+increment)/increment);
x = x*increment;
maxText = ""+x;

5 - Now you just have to use it. Hope it helps
