Use this

Create a new xml file which has the textfields,edittexts,buttons i.e. your login form that you want to show in the popup.Now call the following method where you want to show the popup.

private void callLoginDialog() 
     {
         myDialog = new Dialog(this);
         myDialog.setContentView(R.layout.yourxmlfileID);
         myDialog.setCancelable(false);
         Button login = (Button) myDialog.findViewById(R.id.yourloginbtnID);

          emailaddr = (EditText) myDialog.findViewById(R.id.youremailID);
          password = (EditText) myDialog.findViewById(R.id.yourpasswordID);
          myDialog.show();

         login.setOnClickListener(new OnClickListener()
         {

            @Override
            public void onClick(View v)
            {
                    //your login calculation goes here
            }
        });


     }
