Android简易音乐重构MVVM Java版-新增推荐雷达歌单及重构首页（十三）

关于

  本篇主要介绍引用首页发现api来替换首页轮播何推荐歌单以及新增雷达歌单（根据登陆用户推荐）、实现discoverfragment上下滑动效果。

效果图

在这里插入图片描述

修改ApiService

  添加首页发现api

@GET("homepage/block/page")//首页发现
    LiveData<ApiResponse<HomeDiscoverEntity>> requireHomeDiscover(@Query("refresh") Boolean start);

  项目结构：
在这里插入图片描述

添加HomeDiscoverEntity实体类

  注意，首页发现的json解析实体类最好直接粘贴我的，因为用工具解析的在这个json是必然出错的，因为它涉及到了同一个层级同一个名称不同属性的问题，还有就是部分字段类型解析错误的问题

添加ScrollView实现上下滑动

  修改activity_main.xml:

 <ScrollView
            android:layout_width="match_parent"
            android:layout_height="0dp"
            app:layout_constraintTop_toBottomOf="@id/view_top"
            app:layout_constraintBottom_toTopOf="@id/bottom_nav"
            android:fillViewport="true">
        <androidx.viewpager2.widget.ViewPager2
