  android:selectAllOnFocus="false"  
  android:text="123"  
  android:textIsSelectable="false"  
  android:textSize="16sp"  
  app:ce_digit_width="30dp"  
  app:ce_number_count="4"  
  app:ce_part_count="4"  
  app:ce_parts_space="5" />

Callback listener

As this class extended from EditText, you can use TextWatchers to perform actions before/after/on text change events; however, there is a callback method which tells you is input completed (based on max length) and the length of input numbers. Here is an example:

input.onPinChange { isComplete, length ->  
  Toast.makeText(this,"is Completed=$isComplete, length=$length",Toast.LENGTH_SHORT).show()  
}
