1. Activity를 Dialog화
다양한 형태의 UI화면을 만들고 다이얼로그로 변경하는 방법 1) 기존 Activity를 만든다.
2) AndroidManifest.xml에 Activity를 등록할때 다음 사항을 추가한다.
android:theme="@android:style/Theme.Dialog"
- <activity
- android:name=".dictionary.FindWord"
- android:theme="@android:style/Theme.Dialog"
- />
Dialog App 예제
Text OK Cancel
List
Progress Dialog
Radiobutton Dialog
Checkbok Dialog
Password Dialog
이런 Dialog은

프리퍼런스
값을 수정해서 프로그램 종료하거나 전원을 off후 on하고 다시 실행해도 이전 값이 남아 있는다. xml에 값을 저장하게 된다.
재배포시에 아마도 지워 초기화 될 것이다.
이것은 UI 자체에 저장기능을 사용하는 것이다.
- preferencefrom xml java하나 가 돈다 이것이 저장하고 있는 것이다.
주로 체크박스에 많이 사용한다.
