私は、各行がチェックボックス、テキストビュー、ボタンで構成されているカスタムカーソルアダプタを持っています。 ボタンは、ユーザーがクリックして対応する行を削除できるように、ボタンを表示するチェックボックスを選択すると、最初はGONEに設定されます。CustomCursorで正しいカーソルを取得するAdapater getView（）
私の問題は、getView（）で正しいカーソルを取得できないため、cursorOutOfBoundsExceptionsを取得し続けることです。
私はもはやそれが必要ない場合bindview（）を削除したいと思います。

してください：あなたのgetViewメソッドで
EDIT
まず最初にこれを追加しますか？カーソルをいくつか呼び出すと、どちらが爆発しているかを知る必要があります。 – Barak
これによるとhttp://stackoverflow.com/questions/3535074/getview-vs-bindview-in-a-custom-cursoradapterあなたは 'CustomCursorAdapter'でgetView（）を使うべきではないようですが、 'bindView（）'または 'newView（）'で位置を取得する何らかの方法でなければならない – Roardog
どの行がDeleteCampaignCustomCursorAdapater.java:125ですか？ – Barak
