Reproductor de música Android (cuatro) tocadiscos de disco de música, barra de progreso de sincronización de canciones y pausa/reproducción/continuación de música/cambio de canción hacia arriba y hacia abajo

Este es un proyecto de reproductor de música simple que hice en mi segundo año el año pasado: fue escrito tanto como sea posible para imitar Kugou Music, y las funciones específicas son las siguientes:

1: Animación de inicio: haga clic para ejecutar el programa y aparecerá un video de dos segundos, similar a la animación de inicio de Kugou Music, ¡muy impresionante!

2: Interfaz de registro de inicio de sesión: ¡Ingrese el número de cuenta y la contraseña para verificar la información para iniciar sesión!

3: Carrusel: exactamente igual que Kugou Music, hay un carrusel de ciclo automático sobre la interfaz principal, haga clic en la información de cada imagen del carrusel para ingresar al servicio específico correspondiente, ¡muy puntos extra!

4: giradiscos de grabación de música, barra de progreso de sincronización de canciones y cambio de canción de pausa/reproducción/continuación/arriba y abajo de música.

5: ¡Se realiza la búsqueda de música!

6: ¡Reproduce la columna de video!

7; Se realiza el diseño de la interfaz de información personal, como comentarios, calificación, más, apodo de edad de género, colección, etc.

El tocadiscos del disco de música, la barra de progreso de sincronización de canciones y el código de cambio de canción pausa/reproducción/continuación/arriba y abajo de música son los siguientes:
