Yo sub clasificoSimpleAdapter para agregarle alguna funcionalidad adicional, como cambiar el color de fondo, vistas personalizadas y filtrar. Lo del fondo está funcionando bien, pero el filtro no. Si uso elSimpleFilter el adaptador no proporciona ningún problema, por lo que copié los métodos de la fuente y los puse en mi adaptador. Aunque no toqué nada obtendré unIndexOutOfBoundsException al escribir en el término de búsqueda. Generalmente en el segundo o tercer personaje.

Copié toda la clase pero la parte interesante es laCustomFilter bindView ygetView está funcionando muy bien Después de implementar el filtro cambiado deja de funcionar. La excepción es causada por data.get (posición) en elbindView Método en la primera línea pero el problema tiene que ser el filtro.
