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

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：

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

@NoArgsConstructor
@Data
public class HomeDiscoverEntity {private int code;private DataEntity data;private String message;@NoArgsConstructor@Datapublic static class DataEntity {private String cursor;private List<BlocksEntity> blocks;private boolean hasMore;private Object blockUUIDs;private PageConfigEntity pageConfig;private GuideToastEntity guideToast;private Object internalTest;private List<?> titles;private Object blockCodeOrderList;@NoArgsConstructor@Datapublic static class PageConfigEntity {private String refreshToast;private String nodataToast;private int refreshInterval;private Object title;private boolean fullscreen;private List<String> abtest;private List<String> songLabelMarkPriority;private int songLabelMarkLimit;private String homepageMode;private boolean showModeEntry;private String orderInfo;}@NoArgsConstructor@Datapublic static class GuideToastEntity {private boolean hasGuideToast;private List<?> toastList;}@NoArgsConstructor@Datapublic static class BlocksEntity {private String blockCode;private String showType;private int dislikeShowType;private Object extInfo;private boolean canClose;private int blockStyle;private String action;private String actionType;private UiElementEntity uiElement;private List<CreativesEntity> creatives;private String alg;private String logInfo;@NoArgsConstructor@Datapublic static class UiElementEntity {private SubTitleEntity subTitle;private ButtonEntity button;private String rcmdShowType;@NoArgsConstructor@Datapublic static class SubTitleEntity {private String title;}@NoArgsConstructor@Datapublic static class ButtonEntity {private String action;private String actionType;private String text;private Object iconUrl;}}@NoArgsConstructor@Datapublic static class CreativesEntity {private String creativeType;private String creativeId;private String action;private String actionType;private UiElementEntity uiElement;private List<ResourcesEntity> resources;private String alg;private String logInfo;private int position;@NoArgsConstructor@Datapublic static class UiElementEntity {private MainTitleEntity mainTitle;private ImageEntity image;private List<String> labelTexts;private String rcmdShowType;@NoArgsConstructor@Datapublic static class MainTitleEntity {private String title;}@NoArgsConstructor@Datapublic static class ImageEntity {private String imageUrl;}}@NoArgsConstructor@Datapublic static class ResourcesEntity {private UiElementEntity uiElement;private String resourceType;private String resourceId;private Object resourceUrl;private ResourceExtInfoEntity resourceExtInfo;private String action;private String actionType;private boolean valid;private String alg;private String logInfo;@NoArgsConstructor@Datapublic static class UiElementEntity {private MainTitleEntity mainTitle;private ImageEntity image;private List<String> labelTexts;private String rcmdShowType;@NoArgsConstructor@Datapublic static class MainTitleEntity {private String title;}@NoArgsConstructor@Datapublic static class ImageEntity {private String imageUrl;}}@NoArgsConstructor@Datapublic static class ResourceExtInfoEntity {private long playCount;private boolean highQuality;private int specialType;}}}}}
}

添加BannerExtInfoEntity（新banner的实体类）

@NoArgsConstructor
@Data
public class BannerExtInfoEntity {private List<BannersEntity> banners;@NoArgsConstructor@Datapublic static class BannersEntity {private Object adLocation;private Object monitorImpress;private String bannerId;private Object extMonitor;private Object pid;private String pic;private Object program;private Object video;private Object adurlV2;private Object adDispatchJson;private Object dynamicVideoData;private Object monitorType;private Object adid;private String titleColor;private String requestId;private boolean exclusive;private String scm;private Object event;private String alg;private String s_ctrp;private SongEntity song;private long targetId;private boolean showAdTag;private Object adSource;private Object showContext;private int targetType;private String typeTitle;private Object url;private String encodeId;private Object extMonitorInfo;private Object monitorClick;private Object monitorImpressList;private Object monitorBlackList;private Object monitorClickList;@NoArgsConstructor@Datapublic static class SongEntity {private String name;private int id;private int pst;private int t;private List<ArEntity> ar;private List<?> alia;private int pop;private int st;private String rt;private int fee;private int v;private Object crbt;private String cf;private AlEntity al;private int dt;private HEntity h;private MEntity m;private LEntity l;private SqEntity sq;private HrEntity hr;private Object a;private String cd;private int no;private Object rtUrl;private int ftype;private List<?> rtUrls;private int djId;private int copyright;private int s_id;private int mark;private int originCoverType;private Object originSongSimpleData;private Object tagPicList;private boolean resourceState;private int version;private Object songJumpInfo;private Object entertainmentTags;private int single;private Object noCopyrightRcmd;private int mst;private int cp;private int mv;private int rtype;private Object rurl;private long publishTime;private VideoInfoEntity videoInfo;private List<String> tns;private String alg;@NoArgsConstructor@Datapublic static class AlEntity {private int id;private String name;private String picUrl;private List<String> tns;private String pic_str;private long pic;}@NoArgsConstructor@Datapublic static class HEntity {private int br;private int fid;private int size;private int vd;private int sr;}@NoArgsConstructor@Datapublic static class MEntity {private int br;private int fid;private int size;private int vd;private int sr;}@NoArgsConstructor@Datapublic static class LEntity {private int br;private int fid;private int size;private int vd;private int sr;}@NoArgsConstructor@Datapublic static class SqEntity {private int br;private int fid;private int size;private int vd;private int sr;}@NoArgsConstructor@Datapublic static class HrEntity {private int br;private int fid;private int size;private int vd;private int sr;}@NoArgsConstructor@Datapublic static class VideoInfoEntity {private boolean moreThanOne;private Object video;}@NoArgsConstructor@Datapublic static class ArEntity {private int id;private String name;private List<?> tns;private List<?> alias;}}}
}

添加ScrollView实现上下滑动

  修改activity_main.xml:

 <ScrollViewandroid: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.ViewPager2android:id="@+id/home_viewpager"android:layout_width="match_parent"android:layout_height="@dimen/dp_0"app:layout_constraintTop_toBottomOf="@id/view_top"app:layout_constraintBottom_toTopOf="@id/bottom_nav" /></ScrollView>

新增DiscoverFragmentViewModel

public class DiscoverFragmentViewModel extends ViewModel {public String date = Calendar.getInstance().get(Calendar.DAY_OF_MONTH) + "";public BannerExtInfoEntity bannerList;public List<HomeDiscoverEntity.DataEntity.BlocksEntity.CreativesEntity> recommendList;public List<HomeDiscoverEntity.DataEntity.BlocksEntity.CreativesEntity> selfMgcList;public LiveData<ApiResponse<HomeDiscoverEntity>> requireDiscover(Boolean refresh){return RetrofitUtils.getmApiUrl().requireHomeDiscover(refresh);}}

修改DiscoverFragment布局
