Preference Fragment with android.support.v4.app.Fragment

问题

How to use preference fragment with android.support.v4.app.Fragment? I tried to use android.preference.PreferenceFragment but I got an error: Wrong 2nd argument type/

FragmentTransaction transaction = getFragmentManager().beginTransaction();
            transaction.replace(R.id.fragment_container, new SettingsFragment());
            transaction.addToBackStack(null);
            transaction.commit();

SettingsFragment is the preference fragment

What can solve this problem?

回答1:

By my knowledge PreferenceFragment is not supported in the android.support.v4 library.

You can however use PreferenceFragmentCompat from the support-v7 library.

If it really has to work with the support-v4 library, I would recommend adding the following project as a library project to your application as suggested by this old thread.
