Android 从活动调用片段时，找不到该片段id为0x7f0c0078的视图

在我的应用程序中，我必须调用活动的片段。所以我用的是Frgament mangaer。当我运行代码时，它抛出上面的异常

这是我的主要活动

粘贴片段类。现在我为您的引用添加了代码，并创建了您的片段类。它丢失了。现在我添加了代码供您参考。如果我添加了代码，布局打开了，但太小了，并且在主活动下打开了。您可以设置容器的高度和宽度以正确显示，当然，它将在主活动下显示。片段应该具有父活动。他们不是那样独立的。ohk@vijayg试试看，让我知道。在主活动下显示的页面只是它没有全屏显示如何解决这个问题我已经改变了上面代码中的主活动xml这是我的xml如果我添加代码布局打开了，但太小了，它在主活动下打开了你可以设置容器的高度和宽度要正确显示，当然它将在主活动下显示。片段应该具有父活动。他们不是那样独立的。ohk@vijayg试试看，让我知道。在主活动下显示的页面只是它没有全屏显示如何解决这个问题我已经改变了上面代码中的主活动xml那是我的xml
