Define step value increment for custom RangeSeekBar

[{“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 :
- minText = valueToString(getSelectedMinValue());
- maxText = valueToString(getSelectedMaxValue());
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
