嘗試再次創建片段時調用提交時出錯

我創建了一個片段programmaticaly（沒有在活動佈局中聲明）。但是當我第二次嘗試打開它時，應用程序崩潰，因爲「提交已被稱爲」。嘗試再次創建片段時調用提交時出錯

在活動 - 該功能創建的片段：

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

在片段 - 該功能是關閉的片段：

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

而不是重新使用傳入的事務，創建一個新的FragmentTransaction實例... –

THAAAAAANKSSSSS !!!謝謝你！ = DDD –

回答這個問題，所以我可以標記爲答案^^ –

不是重用傳入的交易中，創建一個新的 FragmentTransaction實例。

感謝

的問題是，你是不是創建一個新的事務，這就是爲什麼你得到這個error.You又要開始一個新的事務：

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

謝謝。
