カスタムリストの行に 、、をListActivity持つを作成しようとしています。CheckBoxTextViewEditText
ユーザーの入力を取得し、その行が選択されたEditTextときにその値をデータベースに保存する必要があります。が選択されていないCheckBox場合、は無効になります。後者はできますが、の値を保持してデータベースに保存することはできません。CheckBoxEditTextEditText
現在、何かを入力してEditText戻るボタンを押してキーパッドを最小化するEditTextと、以前の値に戻ります。
ListViewカスタムを表示し、チェックボックスを選択および選択解除するために、今まで以下をコーディングしました。私はちょうどそのEditText部分で私を助ける必要があります.
