This library is based on the effect in the timely app. I've implemented the standard Roboto font.

you can change the color viewSize and font, these are the fonts you can choose from:

roboto_thin roboto_light roboto_regular roboto_medium roboto_bold roboto_black

please make sure you set the viewSize the same value as the width and height of the view.

Below is an example:

<armijn.vink.numberviewanimation.NumberView 
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:textColor="#1D1D1B"
    app:viewSize="60dp"
    app:font="roboto_thin"/>
