Question

I have an actionbar with a button on the left, a logo in the center and another button on the right. However, whenever I launch a new intent or activity, the whole actionbar “refresh”.

I understand that I need to use Fragments. However, how do I go about implementing that? I saw a lot of examples are fragments with tabs. But I just want my actionbar to remain fixed as I move from one activity to another. I do not have any tabs at all.

Can you please give me examples on how do I go about implementing it? If I have activity A and B. Does that mean I should have 2 fragments?

Many thanks!

If you want to have only 1 action-bar for all activities you will create a FragmentActivity class in which you will display Fragments. Only this FragmentActivity will have a action bar.

You can add, remove, replace Fragments in its(FragmentActivity’s) body and change it when you want, like this

  FragmentManager fmu = getSupportFragmentManager();
  FragmentTransaction transaction = fmu.beginTransaction();
  transaction.replace(R.id.realViewSwitcher_body, English.newInstance()).commit();

Here realViewSwitcher_body is initial View present in FragmentActivity a I replaced it with a Fragment (English.newInstance() its a method with is returning a fragment instance)

This is the whole Scenario either you use Tabs or View-Pager etc and up to my knowledge and experience you can not use Intents for activities having only one Action-bar.
