Tengo un problema que estoy mostrando imágenes en la vista de cuadrícula, que se analiza desde una URL, he diseñado un cuadro de diálogo de búsqueda avanzada para refinar la búsqueda en la vista de cuadrícula, pero el problema es que el análisis sintáctico funciona bien, pero La vista de cuadrícula no se actualiza la próxima vez cuando procesé Refinar búsqueda. Significa que los elementos de Grid View no se actualizan y muestran resultados previos. Por favor, ayúdame a resolver este problema.Actualizar cuadrícula Dyanmically en Android
