Using getFragmentManager() vs getSupportFragmentManager()?

问题

When should I use getFragmentManager() when showing DialogFragments, and when should I use getSupportFragmentManager()?

Currently, I am showing my DialogFragments as follows:

myDialogFragment.show(getFragmentManager(), "My Dialog Fragment");

回答1:

If you are using API >= 14, then use getFragmentManager() and while using Support Package you have to use getSupportFragmentManager()

For Example Android Support Package v4 or v13.

回答2:

When you are using android.support.v4.app.FragmentManager then you should use getSupportFragmentManager() and if you are using android.app.FragmentManager then use getFragmentManager().
