Tengo un adaptador de cursor personalizado donde cada fila consta de una casilla de verificación, una vista de texto y un botón. El botón se establece inicialmente como GONE, cuando el usuario selecciona la casilla de verificación Quiero que se muestre el botón para que el usuario pueda hacer clic en él y eliminar la fila correspondiente.Obtener el cursor correcto en CustomCursor Adapater getView()
Mi problema es que en mi getView() no puedo obtener el cursor correcto, así que sigue obteniendo cursorOutOfBoundsExceptions.
También quiero eliminar el bindView() si no lo necesito más.

Podría publicar la LogCat por favor? Hay varias llamadas al cursor, necesita saber cuál está bombardeando. – Barak
De acuerdo con este http://stackoverflow.com/questions/3535074/getview-vs-bindview-in-a-custom-cursoradapter No parece que debas usar getView() con un 'CustomCursorAdapter', pero hay debe ser una forma de obtener la posición con 'bindView()' o 'newView()' – Roardog
¿Qué línea es DeleteCampaignCustomCursorAdapater.java:125? – Barak
