Android SeekBar example

The layout for the SeekBar.

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/tv_radius"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="5dp"
        android:text="@string/radius"/>
    <SeekBar
        android:id="@+id/seekbar_radius"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:max="@integer/search_redius_max"
        android:layout_toRightOf="@+id/tv_radius"
        android:layout_toLeftOf="@+id/tv_radius_value"/>
    <TextView
        android:id="@+id/tv_radius_value"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingRight="5dp"
        android:layout_alignParentRight="true"
        android:text="@string/radius_value"/>
</RelativeLayout>

Initialize the SeekBar in the activity or fragment. The OnSeekBarChangeListener will update the label to show the current progress of the SeekBar.

tv_radius_value.text = if (seekbar_radius.getProgress() > 1) "${seekbar_radius.getProgress()} miles" else "${seekbar_radius.getProgress()} miles"
seekbar_radius.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {

    override fun onProgressChanged(seekBar: SeekBar, progress: Int, fromUser: Boolean) {
    }

    override fun onStartTrackingTouch(seekBar: SeekBar) {}

    override fun onStopTrackingTouch(seekBar: SeekBar) {
        tv_radius_value.text = if (seekbar_radius.getProgress() > 1) "${seekbar_radius.getProgress()} miles" else "${seekbar_radius.getProgress()} miles"
    }
})
