1. Make TextWatcher (this example for enter only digits into EditText field, you can change it if necessary)

   public class CustomTextWatcher implements TextWatcher{
   
       private static final char space = ' ';
   
   public CodeTextWatcher (){}
   
   @Override
   public void beforeTextChanged(CharSequence s, int start, int count, int after) {
   
   }
   
   @Override
   public void onTextChanged(CharSequence s, int start, int before, int count) {
   }
   
   @Override
   public void afterTextChanged(Editable s) {
   
       // Remove all spacing char
       int pos = 0;
       while (true) {
           if (pos >= s.length()) break;
           if (space == s.charAt(pos) && (((pos + 1) % 2) != 0 || pos + 1 == s.length())) {
               s.delete(pos, pos + 1);
           } else {
               pos++;
           }
       }
   
       // Insert char where needed.
       pos = 1;
       while (true) {
           if (pos >= s.length()) break;
           final char c = s.charAt(pos);
           // Only if its a digit where there should be a space we insert a space
           if ("0123456789".indexOf(c) >= 0) {
               s.insert(pos, "" + space);
           }
           pos += 2;
       }
   }
   

   }

2. Attach this textWatcher to your EditText:

    EditText.addTextChangedListener(new CustomTextWatcher());
