SQLite 홈 검색에서 모든 데이터 가져 오기

Question

SQLite에서 모든 데이터를 가져 오려고 시도 중입니다. Query LIKE 문을 사용합니다. 그러나 나는 그것을 얻는 방법을 모른다.

필터링을하지 않고 모든 데이터를 가져 오는 데 사용하는 Query을 수정하려고합니다. 이미이 문제를 검색하려고 시도하지만 여전히 이해하지 못합니다.

는 여기에 내가 DATABASE의 데이터를 검색하는 의도에서 문자열을 사용하려면 내 Search.java

Intent search = getIntent(); 
    String searchResult = search.getStringExtra("TAG_SEARCH"); 
    DatabaseHandler db = new DatabaseHandler(this); 

    /** 
    * CRUD Operations 
    * */ 
    Log.d("Reading: ", "Reading all contacts.."); 
    List <AllItem> allItems = new ArrayList<AllItem>(); 

    allItems = db.getAllSearchResult(); 

    ArrayList <String> allItems2 = new ArrayList<String>(); 

    for (AllItem cn : allItems) { 
     allItems2.add(cn.getItem_name()); 
     allItems2.add(cn.getAreaNAme()); 
     allItems2.add(cn.getPriceCategory()); 
     allItems2.add(cn.getImageCount()); 
     allItems2.add(cn.getID()); 
     allItems2.add(cn.getCategory_name()); 
     allItems2.add(cn.getKids()); 
     allItems2.add(cn.getFreeTextForKids()); 
     allItems2.add(cn.getDescription()); 
     allItems2.add(cn.getPromotion()); 
     allItems2.add(cn.getPromotionFreeText()); 
     allItems2.add(cn.getPromotionStartDate() + " - "); 
     allItems2.add(cn.getPromotionEndDate()); 
     allItems2.add(cn.getYoutube()); 
     allItems2.add(cn.getYoutubeLink()); 
     allItems2.add(cn.getPhone()); 
     allItems2.add(cn.getMobilePhone()); 
     allItems2.add(cn.getReview()); 
     allItems2.add(cn.getAddress()); 
     allItems2.add(cn.getLatitude()); 
     allItems2.add(cn.getLongitude()); 
     allItems2.add(cn.getOpenDetail()); 
     allItems2.add(cn.getFacebook()); 
     allItems2.add(cn.getTwitter()); 
     allItems2.add(cn.getInstagram()); 
     allItems2.add(cn.getWebsite()); 
    } 


    CustomAdapterAccommodation adapter = new CustomAdapterAccommodation(Search.this, allItems2); 
    listview.setAdapter(adapter); 


} 

입니다.

이 내 DatabaseHandler.java

// Getting All search result 
public List<AllItem> getAllSearchResult() { 
    List<AllItem> allsearchResultList = new ArrayList<AllItem>(); 
    // Select All Query 
    String selectQuery = "SELECT * FROM " + TABLE_ALLITEM; 

    // If i try change like this its show nothing 
    // String selectQuery = "SELECT * FROM " + TABLE_ALLITEM + " WHERE " + KEY_ITEM_NAME_ALLITEM + " = '%a%'";

사람이이 문제를 해결하는 방법에 저를이 도움이 될 수 있습니다? 사용자가 버튼 검색을 누르면 텍스트가 Search 클래스로 전송되고 텍스트는 SQLite에서 모든 데이터를 가져 오는 키입니다. 그런 다음 ListView에 표시하십시오.

Answer 1

사용 LIKE하지 =

LIKE 당신이 wildcars을 사용할 수 있습니다 D : 전에

덕분에 %는 _ 여러 문자를 나타내는 하나 개의 문자

String filter = "a";  
String selectQuery = "SELECT * FROM " + TABLE_ALLITEM + " WHERE " + KEY_ITEM_NAME_ALLITEM + " LIKE '%"+filter+"%' ";
