尝试再次创建片段时调用提交时出错

我创建了一个片段programmaticaly（没有在活动布局中声明）。但是当我第二次尝试打开它时，应用程序崩溃，因为“提交已被称为”。尝试再次创建片段时调用提交时出错

在活动 - 该功能创建的片段：

private void openFragment(Fragment fragment, String tag) { 
    fragmentTransaction.replace(android.R.id.content, fragment, tag); 
    fragmentTransaction.addToBackStack(null); 
    fragmentTransaction.commit(); 
}

在片段 - 该功能是关闭的片段：

private void finish() { 
    getFragmentManager().popBackStack(); 
}

的问题是，你是不是创建一个新的事务，这就是为什么你得到这个error.You又要开始一个新的事务：

fragTransaction = fragManager.beginTransaction(); 
fragTransaction.replace(R.id.old_fragment, newFragment); 
fragTransaction.addToBackStack(null); 
fragTransaction.commit();

谢谢。
