Fragmentneeds to be hosted by a FragmentActivity, you can't add a fragment via an Intent.
Fragment需要由 托管FragmentActivity，您不能通过Intent.
You need to create a FragmentManagerto add your fragment in the FragmentActivity(or call another FragmentActivityvia an Intentand add your fragment on it).
See this topic for more information: Add a Fragment to an Activity at Runtime.
您需要创建一个FragmentManager以将您的片段添加到FragmentActivity（或FragmentActivity通过 an调用另一个Intent并在其上添加您的片段）。
有关更多信息，请参阅此主题：在运行时向活动添加片段。

Fragment TargetFragment=new target_fragment();
FragmentTransaction transaction=getFragmentManager().beginTransaction();
transaction.replace(R.id.main_content,TargetFragment);
transaction.addToBackStack(null);
transaction.commit();

Intent can not be applicable to Activity to Fragment So there Is Another method
Intent 不能应用于 Activity 到 Fragment 所以还有另一种方法
getSupportFragmentManager().beginTransaction().replace(R.id.container,new DashBoardFragment()).commit();
