final ContentResolver cr = context.getContentResolver(); final Cursor cursorImages = cr.query(uriImages, IMAGE_PROJECTION, null, null, "title ASC"); public final Cursor query (Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder)
이미지 파일을 검색해서 리스트 어레이에 넣어주는데요~
title ASC로 정렬을 하게 되면 이름순으로 정렬이 잘됩니다. 그런데 저는 날짜순으로 하고 싶은데요!
date, Date, DATE 넣어봤는데 안되네요.
title 이라는게 테이블 정보같은데 전체 테이블의 정보를 볼 수 있는 방법이 있나요??
아니면 날짜 순으로 정렬할려면 어떤 테이블 명을 써야 될까요!!
답변 부탁드려요!

컨텐트 프로바이더를 사용하실때는 android.provider패키지밑에 관련 클래스가 있습니다. 해당 클래스에 상수로 컬럼명이 정의되있을겁니다 api를 찾아보세요

API를 확인해보니 android.provider.MediaStore.Images.ImageColumns.DATE_TAKEN 을 사용하면
될것 같네요.
될것 같네요.

로그를 찍어보면 이렇게 나오거든요.
DATE_TAKEN, DATE_ADDED, DATE_MODIFIED
그래서 리스트어레이에 저 값들을 다 저장한 후에 날짜 순으로 정렬할려는거였거든요
다들 이런 현상이 발생하네요 ㅎ
static final String[] IMAGE_PROJECTION = {
MediaStore.Images.ImageColumns.DATA,
MediaStore.Images.ImageColumns.DATE_TAKEN
};이걸 쓰고 있는데요. 로그를 찍어보면09-07 05:43:53.895: INFO/CamView(220): /sdcard/DCIM/Camera/1283822387000.jpg

테이블에 날짜 정보를 넣으셨다면 title대신에 날짜 필드를 넣으시면 될텐데요.
테이블에 날짜를 저장하지 않으신것 아닌지?
