Problema ao mudar de tela com fragments

23/03/2017

Estou usando fragments ao inv�s de activity, s� que quando eu chamo o segundo fragment com o m�todo replace, ele n�o sobrep�e completamente o fragment anterior, ele fica por cima, mas o desenho do outro fragment continua aparecendo, como fa�o para que isso n�o aconte�a ?

c�digo da primeira tela

<?xml version="1.0" encoding="utf-8"?>
