RangeSeekBar is an Android Library to show a discrete slider let the user set ranges.

1. Add it in your root build.gradle at the end of repositories:

   allprojects {
   	repositories {
   		...
   		maven { url "https://jitpack.io" }
   	}
   }

2. Add the dependency

   dependencies {
       compile 'com.github.PGrube26:RangeSeekBar:1.2.2'
   }

Add a RangeSeekBar to your xml files and set color, which thumb to draw,...

<net.peterg.android.rangeseekbar.RangeSeekBar
    android:id="@+id/rangeSeekBar1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:showPin="true"
    app:thumbAndSeekBarColor="@color/colorAccent"
    app:thumbToDraw="both" />

• thumbAndSeekBarColor -> changes the color of the thumbs and the seek bar
  • color|reference
• thumbRadius -> changes the radius of the thumbs
  • dimension
• showPin -> shows/hides the pin with current value
  • boolean
• drawPinShadow -> shows/hides a shadow pin with the current value which is always visible
  • boolean
• thumbToDraw -> defines which thumb to draw *leftThumb *rightThumb *both

Data to set in the RangeSeekBar has to implement Parcelable. The text shown in the pins is taken from the toString method of your Object.

rangeSeekBar.setData(listOf(SimpleDataClass("Min", -1), SimpleDataClass("2", 2), SimpleDataClass("3", 3), SimpleDataClass("Max", -1)))

@Parcelize
data class SimpleDataClass(private val label: String, val value: Int) : Parcelable {
    override fun toString() = label
}

Just implement a lambda function for the callbackAction field of the RangeSeekBar:

rangeSeekBar.callbackAction = { bar, leftThumb, rightThumb, fromUser ->
    Timber.d("The bar $bar changed to $leftThumb, $rightThumb and was user intende? $fromUser")
}
