How to close Activity when DialogFragment is created?

Question

Let me tell you all what I have done 'till now. I am showing a dialogfragment on device screen on a button click working perfectly. But now I want is to close activity on button click and show dialogfragment.

Code to open DialogFragment on button click :

button1.setOnClickListener(new OnClickListener() {
@Override
    public void onClick(View v) {
        Bundle bundle=new Bundle();
        bundle.putString("dialogData", data);

        FragmentManager fm = getFragmentManager();
        BuyInfoDilaog dialogFragment = new BuyInfoDilaog();
        dialogFragment.setArguments(bundle);
        dialogFragment.show(fm, "Please Enter your Details");
  }
});

How to deal with this case, does anyone have any idea? Please help. Thanks!

You won't be able to do so. The fragment lifecycle is linked with your activity's one. If you finish the activity, it will destroy the fragment. See :

You can pass the infos to construct your dialog to your previous activity using startActivityForResult and create the dialog then.
