我該如何解決：沒有找到id爲0x7f0d00aa的視圖？

我見過有同樣問題的人，他們說，.replace（）有問題，我已經用fragmentManager.beginTransaction（）構造了片段和容器的寫法。replace （R.id.container，new Fragment（））。commit（）; 而且我必須以其他方式做到這一點，我將其實現到我的代碼中，但我仍然得到了錯誤。錯誤：我該如何解決：沒有找到id爲0x7f0d00aa的視圖？

你可以分享你的'xml'？你確定元素「content_main_container」是你的'activity_main'中的一個子元素嗎？ – Paras

我已經共享這兩個XML文件，如果有幫助。 – CodeLife

No view found for id 0x7f0d00aa (mcshreker.pocketmath:id/content_main_container)

檢查，如果content_main_container在activity_main佈局定義

除了我的content_main_container不在我的activity_main內，它們是兩個不同的XML文件。 – CodeLife

您需要將此佈局（容器）放入活動佈局中。片段將被放置在這個容器中。 – Manza

好了，所以這消除了錯誤（謝謝），但現在當我點擊其中一個片段時，窗口（片段佈局）不會加載，所以我每次都卡在同一個窗口中。此外，還有一堆滯後。我不擔心與片段加載一樣多的延遲。 – CodeLife

我該如何解決：沒有找到id爲0x7f0d00aa的視圖？
