android - 如何在改造多部分请求中获取上传进度百分比？

Question

以下是我正在使用的多部分请求retrofit2。 我想要的是以某种方式获得upload percentage. 但我找不到合适的方法来做到这一点。我见过很少的方法，但它们只是在玩single文件。 我想要实现的是获得合并请求中发送的所有文件的上传进度百分比。

    @Multipart
    @POST("post/vehicle/detail")
    Call<SuccessModel> uploadVehicle(

            @Part("user_id") int userId,
            @Part("name") String vehicleName,
            @Part("number") int stockNumber,
            @Part MultipartBody.Part mainImage,
            @Part MultipartBody.Part hoodsImage,
            @Part MultipartBody.Part bumperImage,
            @Part MultipartBody.Part interiorImage,
            @Part MultipartBody.Part frontSeatImage,
            @Part MultipartBody.Part backSeatImage,
            @Part MultipartBody.Part dashboardImage,
            @Part MultipartBody.Part headLampsImage,
            @Part MultipartBody.Part tailLightsImage,
            @Part MultipartBody.Part backEngineImage
    );
