How to put a title in the fragment?

I have the following code, which calls a fragment, in the ScheduleSearch activity:

@Override
public void openFragment(int home, boolean search, boolean changeClickDirection) {
    if (home == 0) {
        PlaceListScheduleFragment fragment = new PlaceListScheduleFragment();
        Bundle bundle = new Bundle();
        bundle.putInt("home_type", 0);
        bundle.putBoolean("search", true);
        bundle.putBoolean("CHANGE_DIRECTION", changeClickDirection);
        fragment.setArguments(bundle);
        getSupportFragmentManager().beginTransaction()
                .add(R.id.containerLinear, fragment)
                .addToBackStack("PlaceListScheduleFragment")
                .commit();
        getSupportFragmentManager().executePendingTransactions();
    } else {
        PlaceListScheduleFragment fragment = new PlaceListScheduleFragment();
        Bundle bundle = new Bundle();
        bundle.putInt("home_type", 1);
        bundle.putBoolean("search", true);
        bundle.putBoolean("CHANGE_DIRECTION", changeClickDirection);
        fragment.setArguments(bundle);
        getSupportFragmentManager().beginTransaction()
                .add(R.id.containerLinear, fragment)
                .addToBackStack("PlaceListScheduleFragment")
                .commit();
        getSupportFragmentManager().executePendingTransactions();
    }
}

It has a ToolBar implemented, but I can not get it to go a title for the open fragment, how do I do that?
