How I can change the text size in button??

ButtonRectangle extends Button, but you cannot access TextView using buttonRectangle.getTextView(), this will only get you a null object. The author creates a private field (TextView)textButton instead of using Button.getTextView(), so you can only get this field using Java Reflection. Here is my solution:

ButtonRectangle buttonRectangle = (ButtonRectangle) this.findViewById("YOUR BUTTON RESOURCE ID");
try {
   Field textButton = buttonRectangle.getClass().getDeclaredField("textButton");
   textButton.setAccessible(true);
   //Here you can get the textview, then you can do whatever you want
   TextView textView = (TextView) textButton.get(registerButton);
} catch (NoSuchFieldException e) {
   e.printStackTrace();
} catch (IllegalAccessException e) {
   e.printStackTrace();
}
