Número de diálogos personalizados (selector de fecha y hora) en relación con los botones de radio
Tengo un grupo de botones de radio como se muestra en el botón de código a continuación. Cuando hago clic en cada botón de opción, quiero un cuadro de diálogo diferente, como se muestra en la imagen a continuación. Uno para cada botón de opción. Estos deben estar en los cuadros de diálogo. ¿Cómo hago esto?Al final, todo lo que necesito es generar estos diálogos personalizados. ¿Alguien puede ayudarme cómo puedo hacerlo?
También estoy recibiendo una excepción de puntero nulo. ¿Cómo lo resuelvo?
