@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v= inflater.inflate(R.layout.fragment_connect, container, false);
    ip= (EditText) v.findViewById(R.id.editid);
    port= (EditText) v.findViewById(R.id.editport);

//here is my dialog in the activity

final View v=LayoutInflater.from(this).inflate(R.layout.formlayout,null);
       AlertDialog.Builder ab=new AlertDialog.Builder(this);
        ab.setView(v);
        tp= (TextInputLayout) v.findViewById(R.id.ip);
        tp1= (TextInputLayout) v.findViewById(R.id.port);
        tp2= (TextInputLayout) v.findViewById(R.id.appkey);

        ab.setTitle("Enter Connection Details");
        ab.setPositiveButton("confirm", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

                String a=tp.getEditText().getText().toString();
                String b=tp1.getEditText().getText().toString();
                String c=tp2.getEditText().getText().toString();
                if(!TextUtils.isEmpty(a)&&!TextUtils.isEmpty(b) && !TextUtils.isEmpty(c))
                {
                    SharedPreferences.Editor edit=sp.edit();
                    edit.putString("ip",a);
                    edit.putString("port",b);
                    edit.putString("appkey",c);
                    edit.commit();
                }
            }
        });
        ab.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        });
        AlertDialog abc=ab.create();
        abc.show();
        abc.setOnDismissListener(new DialogInterface.OnDismissListener() {
            @Override
            public void onDismiss(DialogInterface dialog) {

            }
        });

Answer 1

abc.show();
abc.setOnDismissListener(new DialogInterface.OnDismissListener() {
    @Override
    public void onDismiss(DialogInterface dialog) {
        fragmentInstance.refreshEditTextValue(value);
    }
 });

In your fragment :

 public refreshEditTextValue(String value) {
//TODO set value in edittext
    }
