 Typeface typeFace = Typeface.createFromAsset(getAssets(), "fonts/Font-Bold.ttf");
  /**  *Set TypeFace for the font in keys of keypad  */ passCodeView.setTypeFace(typeFace);
  /**  * Set color for the keypad text  * @param color - Resource id of the color to be set  */ passCodeView.setKeyTextColor(getResources.getColor(R.color.black));

 passcode string to be set  */ public void setPassCode("8854")  /**  * Reset the code to empty  */ passCodeView.reset();
  /**  * Set drawable for empty digits programmatically  */  passCodeView.setEmptyDrawable(R.drawable.empty);
  /**  * Set drawable for filled digits programmatically  */  passCodeView.setFilledDrawable(R.drawable.filled);
  /**  * Attach {
