How to show tick marks for Discrete Slider?

Now you can use the Slider in the Material Components Library.
The tick marks are displayed by default in the discrete sliders.

    <com.google.android.material.slider.Slider
        android:valueFrom="0"
        android:valueTo="10"
        android:stepSize="1"
        .../>

enter image description here


Add tick marks with the style attribute:

<SeekBar
    android:id="@+id/seekBar"
    style="@style/Widget.AppCompat.SeekBar.Discrete"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:max="10"
    />

Or add them manually by setting the tickMark drawable:

<SeekBar
    android:id="@+id/seekBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:max="10"
    android:tickMark="@drawable/tickmark"
    />

tickmark.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="oval">
    <size android:width="4dp"
          android:height="4dp"/>
    <solid android:color="@android:color/white"/>
</shape>
