ListView重複最後一個條目

Question

我做了一個listView與自定義適配器它從數據庫獲取數據並將其綁定到列表視圖，適配器選取記錄數很好，但它不斷顯示所有條目的最後記錄，例如如果有5條記錄從數據庫檢索列表視圖將顯示五次最後一個記錄。

這裏是代碼

Activities SetAct = new Activities(); 
final ArrayList<Activities> sData = new ArrayList<Activities>(); 
try{ 
    SQLiteDatabase db = openOrCreateDatabase("iTimeDB", MODE_PRIVATE, null); 
    Cursor c2 = db.rawQuery("SELECT * FROM Activities", null); // WHERE ID = '" +ID+"'" 
    for (c2.moveToFirst(); !c2.isAfterLast(); c2.moveToNext()) { 
     String title =c2.getString(c2.getColumnIndex("Title")); 
     String details =c2.getString(c2.getColumnIndex("Details")); 
     String time =c2.getString(c2.getColumnIndex("Time")); 
     String ref= c2.getString(c2.getColumnIndex("Ref")); 
     String matter =c2.getString(c2.getColumnIndex("Matter")); 
     String date = c2.getString(c2.getColumnIndex("Date")); 
     String ID = c2.getString(c2.getColumnIndex("ID")); 
     String IMEI1 = c2.getString(c2.getColumnIndex("IMEI")); 
     SetAct.setTitle(title); 
     SetAct.setDetails(details); 
     SetAct.setMatter(matter); 
     SetAct.setRef(ref); 
     SetAct.setTime(time); 
     SetAct.setDate(date); 
     SetAct.setID(ID); 
     sData.add(SetAct); 
     } 
    c2.close(); 
    db.close(); 
    } 
    catch(Exception e){ 
     e.printStackTrace(); 
     Log.v("YYY", e.toString()); 
    } 
    final ListView listView = (ListView) findViewById(R.id.listView1); 
    listView.setAdapter(new CustomListAdapter(this, sData)); 

Answer 1

從外下面行中刪除爲循環在添加它內部爲循環

Activities SetAct = new Activities(); 

例

for (c2.moveToFirst(); !c2.isAfterLast(); c2.moveToNext()) { 
     Activities SetAct = new Activities(); 
     String title =c2.getString(c2.getColumnIndex("Title")); 
     // Remaining as it is.. 
} 

Answer 2

這樣使用。

我使用以下模式來讀取查詢結果。

SQLiteDatabase db = new DbHelper().getWritableDatabase(); 
    String sql = "SELECT ..."; 
    String[] args = ...; 
    Cursor cs = db.rawQuery(sql, args); 
    while (cs.moveToNext()) { 
     // cs.getXxx(0), cs.getXxx(1) 
    } 
    cs.close(); 
    db.close(); 

DbHelper是我從SQLiteOpenHelper
