Primero, voy a buscar todos los mensajes a mi aplicación para almacenarlos en la vista de lista y luegoEstoy seleccionando mensajes de la vista de lista usando casillas de verificación y deseoenvíe estos sms seleccionados a un solo número que esté predefinido y deseouse los sms seleccionados como cuerpo de mensaje para enviarlos al no. pero elproblema es que elel mensaje enviado contiene los mensajes completos de listview, no el seleccionado. Asi que por favor alguiencorrigeme donde me equivoco en el codigo como deseoenviar solo los mensajes seleccionados, no los elementos de la vista de lista completa (mensajes)
