Dear ladies and gents,
First of all, please do not mark my question down. If you think that my question is too stupid please let me know and i will edit it or remove.
So my actual question is that I have an activity ( extends Activity
). In that activity's layout I created FrameLayout
where I then attach different four fragments(so each of them extends Fragment
. So in one of that fragments I would like to implements swipeable tabs(see screenshot).
I know that it is usually done by implementing viewPager and FragmentPagerAdapter, but I can not do this as if I'm calling getSupportFragmentManager
in my fragment it gives my an error. If i am using getActivity().getFragmentManager()
it gives me error that android.support.v4.app.fragmentmanager cannot be applied to android.app.fragmentmanager . I have to use android.support.v4.app.fragment in my fragment, because otherwise I will not be able to implement my activity's view(described at the beggining).
Any ideas or suggestions would be very appreciated. screenshot
Make sure you are using Fragment
class that you extends your fragments comes from support library. You also need to use FragmentActivity
to call method getSupportFragmentManager();
On the other hand, viewpager
which is in your fragment need to implemented as usual that you can find on internet except getChildSupportFragmentManager();
This one called "nested fragments".
PS: I am not sure but you can also use AppCompatActivity
instead of FragmentActivity
. FragmentActivity
and ActionBarActivity
must be deprecated .
Good luck
在其他Fragment中使用Fragment时,可以使用getChildFragmentManager()。
New version of Support Library v4 (Android 4.2) resolve this problem. For do this, simply do constructor of your custom FragmentPagerAdapter like this:
public CustomFragmentPagerAdapter(android.support.v4.app.Fragment fragment)
{
super(fragment.getChildFragmentManager());
// write your code here
}
This work because new Android version approve using nested Fragments
