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

Make a function like that

public void openFragment(Fragment fragment) {
        FragmentManager manager = getSupportFragmentManager();
        manager.beginTransaction().replace(R.id.fragmentContainer, fragment).commit();
    }

and call this in your onCreate Method

 openFragment(new yourFragment());

In your beginTransaction().replace method you have to pass the view from which you want to replace your fragment with
