好吧，伙计们，我在尝试将 fragment 放入 onCreate() 中的框架时遇到错误，我的应用程序有一个名为“fragment_home”的选项卡的 Split View，该选项卡有 2 个按钮，一个用于 ir 的 ListView ，一个用于 ir 的 ListView 其他用于它的 map View ，当单击此按钮时， fragment 会出现在位于按钮顶部的框架上............ ........................

Answer 1

而不是使用替换 fragment ，使用添加 fragment 和删除 fragment ..

我已经在我的一个应用程序中执行了此操作。它工作正常。
