在ListView中顯示SQLite

Question

嗨，我有一個SQLite數據庫，我用一個簡單的遊標讀取數據庫，然後將其顯示給TextView。但是，我想在ListView中顯示數據。

所以我有字符串，但我不知道如何在ListView中顯示它。有沒有簡單的方法，還是我必須創建一個適配器？

我還想知道如何設置列表視圖的部分到標題和其他人的子標題。如果可能的話，我希望每行都是不同的列表項。

Answer 1

使用SimpleCursorAdapter。

下面是一個簡單的例子：

yourListView.setAdapter(new SimpleCursorAdapter(
    /* The context where the ListView associated with this SimpleListItemFactory is running */, 
    /* resource identifier of a layout file that defines the views for this list item. The layout file should include at least those named views defined in "to" */, 
    /* The database cursor. Can be null if the cursor is not available yet. */, 
    /* A list of column names representing the data to bind to the UI. Can be null if the cursor is not available yet. */, 
    /* The views that should display column in the "from" parameter. These should all be TextViews. The first N views in this list are given the values of the first N columns in the from parameter. Can be null if the cursor is not available yet. */, 
    /* Flags used to determine the behavior of the adapter, as per CursorAdapter(Context, Cursor, int). */));

下面是一個簡單example.Lets說你有兩個數組列表命名爲您的主要活動「項目」和「ItemsId」。 現在，在您的數據庫處理程序類中獲取您的表並使用以下代碼將值存儲到Items和ItmesId數組列表中。

MainActivity.Items.clear(); 
    MainActivity.ItemsId.clear(); 

    // Select All Query 
    String selectQuery = "SELECT * FROM " + TABLE_NAME; 

    SQLiteDatabase db = this.getWritableDatabase(); 
    Cursor cursor = db.rawQuery(selectQuery, null); 

    // looping through all rows and adding to list 
    if (cursor.moveToFirst()) { 
     do { 
      // Adding values to list 
      MainActivity.Items.add(cursor.getString(0)); 
      MainActivity.ItemsId.add(cursor.getString(0)); 
      } while (cursor.moveToNext()); 
    } 

現在使用主活動中的Items數組列表填充您的列表視圖。

final StableArrayAdapter adapter = new StableArrayAdapter(this, 
    android.R.layout.simple_list_item_1, Items); 
listview.setAdapter(adapter);
