实战:慕课App 学习Tab页数据请求与绑定

接口编写

private var retrofit: Retrofit = Retrofit.Builder()
        .client(client)
        .baseUrl("https://www.songyubao.com/")
        .addConverterFactory(GsonConverterFactory.create())    //数据转换适配器
        .build()

class ApiService{
    @GET(value = "static/book/assets/study.json")
    fun getStudy(): Call<List<Course>>
}

数据模型

data class Course(
    val label: String,
    val poster: String,
    val progress: String,
    val title: String
)

数据绑定

 override fun onBindViewHolder(holder: StudyViewHolder, position: Int) {
            val course = datas[position]
            holder.itemView.item_course_title.text = course.title
            holder.itemView.item_course_label.text = course.label
            holder.itemView.item_course_progress.text = "已学.${course.progress}"
        }
