I have an app with a screen and on this screen there is a fragment. In this fragment there is a button that, when clicked, I want to call another fragment and that is / replace the button fragment. I've been trying some things I've seen on the web and I'm not getting it.

Your Activity should have <fragment> :

      <fragment
         android:id="@+id/
         android:layout_width="match_parent"
         android:layout_height="match_parent"/>

Try this:

/**
 * Informe a Activity onde está localizado o fragmnet container, 
 * O Fragment que será exibido.
 * O nome da Fragment
 **/
    public static final void abrir(final SuaActivity mActivity, final Fragment mFragment, final String name) {
        if (null == mActivity || null == mFragment) {
            return;
        }
        final FragmentManager _manager = mActivity.getFragmentManager();
        final FragmentTransaction _transaction = _manager.beginTransaction();
        _transaction.add(R.id.container, mFragment, name);
        /**
         * Adiciona à pilha!
         * Isso significa que a transação será lembrada depois que ela for comprometida e irá reverter sua operação quando mais tarde sair da pilha.
         */
        _transaction.addToBackStack(name);
    }
