Open a new Fragment by replacing the current one

newfragment.java

//this is the method
//R.id.frame should be R.id.name_of_your_frame_layout
public void goToFragment(Fragment fragment) {
        FragmentTransaction transaction = getFragmentManager().beginTransaction();
        transaction.replace(R.id.frame, fragment);
        transaction.addToBackStack(null);
        transaction.commit();
    }


//this is how you use it
gotoFragment(new AnotherFragment());


//Make sure the new fragment has a constructor (well you have to have it anyways)
