如何从Android中的按钮单击从一个片段转到另一个片段？
我正在研究android中片段之间的事务，我有一个片段包含一些relativelayout，在每个布局上我都要打开一个新片段，所以我引用了很多链接并尝试如下，但它一直给我错误，所以请建议我在我的代码中哪里出错，请保存我，提前谢谢。

试试这个：
示例：
DetailDashBoardFragment fragment = new DetailDashBoardFragment();
FragmentTransaction ft = getChildFragmentManager().beginTransaction();
ft.replace(R.id.show_fragment, fragment).addToBackStack(null);
ft.commit();
编辑：
android.app.Fragment fr;
fr = new DetailDashBoardFragment();
FragmentManager fm = getFragmentManager();
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.replace(R.id.show_fragment, fr);
fragmentTransaction.commit();
希望它有所帮助。
答案 1 :(得分：0)
请尝试以下代码：
Fragment fragment = new MoveSearchStudentFragment();
FragmentManager fm = getActivity().getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.content_frame, fragment);
ft.commit();
