How to start a Fragment/Activity within Fragment?

Question

I have a button in Fragment. When Button is clicked it has to Open new Fragment/Activity within Fragment. I have written code using Intent, Intent i = new Intent(); i.setClass(getActivity(), UpdateProfile.class); startActivity(i); but its opening in new activity like in below image.

My requirement is in Picture 1. Can someone suggest me how to do it?

EDIT: As suggested by rai and ADK, its working fine but new fragment overlays on old fragment. See the below image. "Change Password"(TextView) is New Fragment which overlays on existing fragment.

Solution 1

Try:

getFragmentManager()
    .beginTransaction()
    .replace(containerViewId, newFragment)
    .addToBackStack(null) // enables back key
    .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE) // if you need transition
    .commit();

Solution 2

You should to use FragmentTransaction enter link description here.

Like this

        FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
        fragmentTransaction.replace(R.id.yourFragment, YourFragmentWithImageClass.getInstance());
        fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
        fragmentTransaction.commit();

in your Activity
