拡張可能なリストビューで特定の親に子を追加する方法

制限を10に設定してsqliteからデータをロードしたアプリケーションを作成しました。リストがスクロールされると、sqliteから別の10個のデータをロードしますこの部分の非同期タスク私はヘッダーグループと子データをフェッチしましたが、新しい日付の子を入れる方法を知らない人は、拡張可能リストビューの特定の親に子を追加する方法を教えてください。拡張可能なリストビューで特定の親に子を追加する方法

データがsqliteに格納される方法のスナップショットを投稿できます – avinash

子リストの各グループの最後の子として追加する必要があります。 getChildView（）メソッドの条件を追加して、行が子タイプかより多くのタイプをロードしているかを確認します。 –

この前の返信を確認してください： [** http：//stackoverflow.com/a/15348971/2153132**]（http://stackoverflow.com/a/15348971/2153132） –

あなたはonCreateメソッド内のListViewのアダプタを初期化する必要があります：バックグラウンド方法では、あなただけのデータをロードして、いくつかのクラスatributeに保存する必要があり、後

listView.setAdapter(adapter); // Pode ser com as listas vazias

。後、onPostResult方法では、あなたは、アダプタを更新し、リストビューに通知する必要があります。

protected void onPostExecute(String disorderedlist) { 
    adapter.addGroupList(groupList); // Need to implement the method in the adapter 
    adapter.addChildList(childList); // Need to implement the method in the adapter 
    adapter.notifyDataSetChanged(); 
    loadingMore = false; 
}

これは、あなたのロジックに変更アイデアです。
