您好我是Android开发的新手，我在使用导航抽屉的片段中的listview中显示联系人列表时遇到问题
列表实际上正在运行，但它打开了＆＃34;新窗口＆＃34;而不是在碎片内部
抱歉我的英文不好在我的src文件夹中我有： - MainActivity.java - HomeFragment.java - FindPeopleFragment.java - ContactsActivity.java .....
在我的布局文件夹中我有： - activity_main.xml - fragment_home.xml - fragment_find_people.xml - lv_layout.xml .....

任何帮助请!!

问题在于您的FindPeopleFragment，您从Activity开始onCreateView，而应该设置Fragment layout并在Fragment中执行其他处理}
将所有代码从ContactsActivity移至FindPeopleFragment。您可以在膨胀视图中找到Fragment布局中的视图，如下所示
// Getting reference to listview
ListView lstContacts = (ListView) rootView .findViewById(R.id.listview);
更改onCreateView的{{1}}并执行所有其他操作
FindPeopleFragment
