從SQLite槽搜索中獲取所有數據

我試圖使用Query LIKE語句從我的SQLite中獲取所有數據。但我不知道如何得到它。從SQLite槽搜索中獲取所有數據

我嘗試修改Query，我用它來獲取所有數據而沒有過濾，並且它的工作正常。我已經嘗試搜索這個問題，但我仍然不明白。

這裏是我的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); 


}

我想使用String從意向上搜索DATABASE數據。

這是我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%'"; 


    Log.d("Query search", selectQuery); 
    SQLiteDatabase db = this.getWritableDatabase(); 
    Cursor cursor = db.rawQuery(selectQuery, null); 

    // looping through all rows and adding to list 
    if (cursor.moveToFirst()) { 
     do { 
      AllItem allitem = new AllItem(); 
      allitem.setTableID(cursor.getInt(0)); 
      allitem.setID(cursor.getString(1)); 
      allitem.setCategory_name(cursor.getString(2)); 
      allitem.setItem_Name(cursor.getString(3)); 

      allitem.setDescription(cursor.getString(4));

      allsearchResultList.add(allitem); 
     } while (cursor.moveToNext()); 
    } 

    // return food list 
    return allsearchResultList; 
}

是否有任何人能幫助我如何解決這個問題呢？當用戶按下按鈕搜索，文本發送到Search類和文本是從SQLite獲取所有數據的關鍵。然後顯示在ListView。

使用LIKE不等於

LIKE允許你使用wildcars：％多個字符表示 _代表一個字符

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

如何使用由用戶輸入成爲搜索的關鍵？ – Matthew 2014-09-04 15:28:34

用從用戶輸入中獲得的字符串替換過濾器的值。 – 2014-09-04 15:30:07

如果它在不同的課上呢？如你看到的。我將數據庫處理程序稱爲搜索類。 – Matthew 2014-09-04 15:32:22
