我正在尝试从活动切换到片段。我确实认为我的代码是正确的。但我仍然在logcat中收到错误，它无法加载视图。请告诉我我错在哪里。

答案 0 :(得分：0)
从检查错误输出来看，我觉得这一行：
transaction.replace(R.id.content_frame, newFragment);
发出错误。您确定您有＆＃34; content_frame＆＃34;？
的布局文件答案 1 :(得分：0)
当您使用片段事务在onClick中添加WordFragment时，它抱怨它无法找到ID为content_frame的父视图来放置片段。
检查以确保home.xml布局中有一个id为content_frame的容器作为此片段的父级。
