}

* 10 : 타이틀바 없애기

* 17-18 : Intent 에서 data 가져오기

* 25-27 : Intent로 data 전달하기

* 34-40 : 바깥 레이어를 눌러도 닫히지 않게 하기

* 43-46 : 안드로이드 백버튼 막기

AndroidMenifest.xml

        <!-- 팝업 Activity -->
        <activity android:name=".PopupActivity" android:theme="@android:style/Theme.Dialog" />

* Popup으로 띄울 Activity의 Theme를 바꿔줍니다

 

 

결과

* 팝업 호출(데이터 전달) -> 팝업에서 전달받은 데이터 보여줌 , 팝업 닫기(데이터 전달) -> 데이터 받아서 보여줌
