Android: How to call Fragment class from activity

问题:

I am trying to call a Fragment class from Activity using Intent. Is it possible to implement. Please provide your views.

回答1:

Fragment needs to be hosted by a FragmentActivity, you can't add a fragment via an Intent.

You need to create a FragmentManager to add your fragment in the FragmentActivity (or call another FragmentActivity via an Intent and add your fragment on it).
See this topic for more information: Add a Fragment to an Activity at Runtime.

            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

getSupportFragmentManager().beginTransaction().replace(R.id.container,new DashBoardFragment()).commit();
