create a layout like below
activity_main.xml
=============
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@color/grey_500"
android:orientation="vertical">
</FrameLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="@color/grey_100"
android:orientation="vertical">
<RelativeLayout
android:id="@+id/tick_mark_labels_rl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="8dp" />
<com.etiennelawlor.discreteslider.library.ui.DiscreteSlider
android:id="@+id/discrete_slider"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_marginBottom="4dp"
android:background="@color/grey_100"
android:paddingLeft="8dp"
android:paddingRight="8dp"
app:backdropFillColor="@color/grey_200"
app:backdropStrokeColor="@color/grey_300"
app:backdropStrokeWidth="1dp"
app:horizontalBarThickness="4dp"
app:position="0"
app:progressDrawable="@drawable/transparent_progress_drawable"
app:tickMarkCount="4"
app:tickMarkRadius="8dp" />
</LinearLayout>
</LinearLayout>
======
create a drawable with an image like below. I have created four files like this. please see source code for reference.
ubergo.xml
=========
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<size
android:width="40dp"
android:height="40dp" />
<stroke
android:width="8dp"
android:color="@color/fifty_percent_transparency_primary" />
<solid android:color="@color/colorPrimary" />
<corners android:radius="1dp" />
</shape>
</item>
<item>
<bitmap
android:gravity="center"
android:src="@drawable/ic_directions_car_black_24dp" />
</item>
</layer-list>
<array name="icons">
<item>@drawable/uber_pool</item>
<item>@drawable/uber_moto</item>
<item>@drawable/uber_go</item>
<item>@drawable/uber_suv</item>
</array>
