Attach a Fragment to the Activity

Question

I am trying to attach a Fragment to my MainActivity programmatically by using the following code:

@Override
protected void onCreate(Bundle savedInstanceSta         


        

Answer 1

Replace your code:

FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
MainFragment fragment = new MainFragment();
fragmentTransaction.add(R.id.activity_main,fragment);
fragmentTransaction.commit();

By this:

Fragment fragment = new MainFragment();
getSupportFragmentManager.begintransaction.replace(R.id.container,fragment).commit;
