java类型的方法和构造函数未定义
我有这样的错误信息
The method setContentView(int, FindPeopleFragment) is undefined for the type FindPeopleFragment
The constructor BoxOfficeMoviesAdapter(FindPeopleFragment, ArrayList<BoxOfficeMovie>) is undefined
The constructor Intent(FindPeopleFragment, Class<BoxOfficeDetailActivity>) is undefined
那么,我需要在代码中改进什么呢?这是我的代码,我想在FindPeopleFragment中显示ListView票房

在片段中,将上下文传递给构造函数时,使用
getActivity()
而不是this
改变这个
到
必须移除
setContentview
是活动类的方法,而不是Fragment
换成
进一步
getView()
返回null改变这个
到
终于改变了
到
在继续之前,您最好先阅读片段文档
