Introducción
La forma más fácil de reproducir video en Android es usar VideoView incorporado en el SDK y luego agregar MediaController para controlar la pausa de reproducción de video, etc., pero esto tiene la desventaja de que no puede personalizar su propia interfaz de usuario de control, así que aquí es un control de reproducción personalizado. Puede establecer una variedad de atributos personalizados (como estilo de carga, video de error, etc.), y es fácil cambiar entre pantalla completa y pantalla no completa, y es compatible con Android V2.3 y superior sistemas.
