android简易音乐重构MVVM Java版-BottomNavigationView+viewpager主界面结构（十一）
关于
本篇主要记录新增discoverFragment（发现界面）及banner展示、以及使用lombok替代冗余的get、set方法等。
效果图
Android使用Lombok
参考《Android使用GsomFormatPlus+Lombok简化定义实体类》
修改Login的实体类：
@NoArgsConstructor
@Data
public class LoginEntity
private int loginType;
private int code;
private AccountEntity account;
private String token;
private ProfileEntity profile;
private List<BindingsEntity> bindings;
private String cookie;
@NoArgsConstructor
@Data
public static class AccountEntity
private int id;
private String userName;
private int type;
private int status;
private int whitelistAuthority;
private long createTime;
private String salt;
private int tokenVersion;
private int ban;
private int baoyueVersion;
private int donateVersion;
private int vipType;
private long viptypeVersion;
private boolean anonimousUser;
private boolean uninitialized;
@NoArgsConstructor
@Data
public static class ProfileEntity
private String backgroundImgIdStr;
private int userId;
private String avatarImgIdStr;
private boolean followed;
private String backgroundUrl;
private String detailDescription;
private int userType;
private int vipType;
private int gender;
private int accountStatus;
private long avatarImgId;
private String nickname;
private long backgroundImgId;
private long birthday;
private int city;
private String avatarUrl;
private boolean defaultAvatar;
private int province;
private Object expertTags;
private ExpertsEntity experts;
private boolean mutual;
private Object remarkName;
private int authStatus;
private int djStatus;
private String description;
private String signature;
private int authority;
private String avatarImgId_str;
private int followeds;
private int follows;
private int eventCount;
private Object avatarDetail;
private int playlistCount;
private int playlistBeSubscribedCount;
@NoArgsConstructor
@Data
public static class ExpertsEntity
@NoArgsConstructor
@Data
public static class BindingsEntity
private int userId;
private String url;
private boolean expired;
private String tokenJsonStr;
private long bindingTime;
private int expiresIn;
private int refreshTime;
private long id;
private int type;
然后删除对应的Login_bean实体类，替换一下其他使用到的地方即可。
添加cookie和cache引用
修改moudle的build文件新增cookie引用：
// CookieJar
implementation 'com.github.franmontiel:PersistentCookieJar:v1.0.1'
新增 ApplicationContextProvider
public class ApplicationContextProvider extends ContentProvider
@SuppressLint("StaticFieldLeak")
public static Context context;
@Override
public boolean onCreate()
context = getContext();
return false;
@Nullable
@Override
public Cursor query(@NonNull Uri uri, @Nullable String[] projection, @Nullable String selection, @Nullable String[] selectionArgs, @Nullable String sortOrder)
return null;
@Nullable
@Override
public String getType(@NonNull Uri uri)
return null;
@Nullable
@Override
public Uri insert(@NonNull Uri uri, @Nullable ContentValues values)
return null;
@Override
public int delete(@NonNull Uri uri, @Nullable String selection, @Nullable String[] selectionArgs)
return 0;
@Override
public int update(@NonNull Uri uri, @Nullable ContentValues values, @Nullable String selection, @Nullable String[] selectionArgs)
return 0;
然后再androidmanifest.xml的application中添加provider：
<provider
android:name=".ApplicationContextProvider"
android:authorities="$applicationId.contextProvider"
android:exported="false" />
然后定义ContextProvider.java用来单例获取context：
public class ContextProvider
@SuppressLint("StaticFieldLeak")
private static volatile ContextProvider instance;
private final Context mContext;
private ContextProvider(Context context)
mContext = context;
/**
* 获取实例
*/
public static ContextProvider get()
if (instance == null)
synchronized (ContextProvider.class)
if (instance == null)
Context context = ApplicationContextProvider.context;
if (context == null)
throw new IllegalStateException("context == null");
instance = new ContextProvider(context);
return instance;
/**
* 获取上下文
*/
public Context getContext()
return mContext;
public Application getApplication()
return (Application) mContext.getApplicationContext();
添加cookie和cache
修改RetrofitUtils.java：
public class RetrofitUtils
/**
* 单例模式
*/
public static ApiService apiService;
public static ApiService getmApiUrl()
if (apiService == null)
synchronized (RetrofitUtils.class)
if (apiService == null)
apiService = new RetrofitUtils().getRetrofit();
return apiService;
private ApiService getRetrofit()
//初始化Retrofit
ApiService apiService = initRetrofit(initOkHttp()).create(ApiService.class);
return apiService;
private OkHttpClient initOkHttp()
File cacheDir = ContextProvider.get().getContext().getCacheDir();
long cacheSize = 10L * 1024L * 1024L; // 10 MiB
ClearableCookieJar cookieJar = new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(ContextProvider.get().getContext()));
return new OkHttpClient().newBuilder()
.readTimeout(Constant.DEFAULT_TIME, TimeUnit.SECONDS) //设置读取超时时间
.connectTimeout(Constant.DEFAULT_TIME, TimeUnit.SECONDS) //设置请求超时时间
.writeTimeout(Constant.DEFAULT_TIME, TimeUnit.SECONDS) //设置写入超时时间
.addInterceptor(new LogInterceptor()) //添加打印拦截器
.retryOnConnectionFailure(true) //设置出错进行重新连接
.cache(new Cache(cacheDir, cacheSize)) //cache
.cookieJar(cookieJar) //cookie
.build();
/**
* 初始化Retrofit
*/
@NonNull
private Retrofit initRetrofit(OkHttpClient client)
return new Retrofit.Builder()
.client(client)
.baseUrl(Constant.BaseUrl)
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addCallAdapterFactory(LiveDataCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
修改添加侧滑栏和底部导航栏
修改activity_main.xml布局文件：
