Android AIDL技术实战项目-音乐播放器（二）-使用retrofit完成音乐API的封装

使用retrofit完成音乐API的封装

音乐API http://blog.csdn.net/zuiaisha1/article/details/61200422

代码结构

1、导入retrofit相关库

compile 'com.squareup.retrofit2:retrofit:2.2.0'

2、编写接口API

public interface MusicApi { String MUSIC_BASE_URL = "http://tingapi.ting.baidu.com/"; String SUB_URL = "v1/restserver/ting"; @GET(SUB_URL) Call<PaySongBean> getPaySongData(@QueryMap Map<String, String> params); @GET(SUB_URL) Call<SongLrcBean> getSongLrcData(@QueryMap Map<String, String> params); @GET(SUB_URL) Call<SongBillListBean> getSongBillListData(@QueryMap Map<String, String> params); @GET(SUB_URL) Call<SearchSongBean> getSearchSongData(@QueryMap Map<String, String> params); @GET(SUB_URL) Call<RecommandSongListBean> getRecommandSongList(@QueryMap Map<String, String> params); //未使用的 // @GET(SUB_URL) // Call<SongLrcBean> downSong(@QueryMap Map<String, String> params); // // // @GET(SUB_URL) // Call<SongLrcBean> getSingerInfo(@QueryMap Map<String, String> params); // @GET(SUB_URL) // Call<SongLrcBean> getSingerSongList(@QueryMap Map<String, String> params); }

3、二次封装

public class NetManager { private Retrofit mRetrofit; private MusicApi mMusicApi; private OkHttpClient mClient; /** * 播放音乐 * * @param songid * @param callBack */ public void getPaySongData(String songid, NetCallBack<PaySongBean> callBack) { Map<String, String> params = NetHelper.getMusicApiCommonParams("baidu.ting.song.play"); params.put("songid", songid); createMusicApi() .getPaySongData(params) .enqueue(callBack); } /** * 播放音乐 * * @param songid * @param callBack */ public void getSongLrcData(String songid, NetCallBack<SongLrcBean> callBack) { Map<String, String> params = NetHelper.getMusicApiCommonParams("baidu.ting.song.lry"); params.put("songid", songid); createMusicApi() .getSongLrcData(params) .enqueue(callBack); } /** * 推荐列表 * @param songid * @param num * @param callBack */ public void getRecommandSongList(String songid, String num, NetCallBack<RecommandSongListBean> callBack) { Map<String, String> params = NetHelper.getMusicApiCommonParams("baidu.ting.song.getRecommandSongList"); params.put("songid", songid); params.put("num", num); createMusicApi() .getRecommandSongList(params) .enqueue(callBack); } /** * 搜索 * @param query * @param callBack */ public void getSearchSongData(String query, NetCallBack<SearchSongBean> callBack) { Map<String, String> params = NetHelper.getMusicApiCommonParams("baidu.ting.search.catalogSug"); params.put("query", query); createMusicApi() .getSearchSongData(params) .enqueue(callBack); } /** * @param type 1-新歌榜,2-热歌榜,11-摇滚榜,12-爵士,16-流行,21-欧美金曲榜,22-经典老歌榜,23-情歌对唱榜,24-影视金曲榜,25-网络歌曲榜 * @param size 返回条目数量 * @param offset 获取偏移 * @param callBack */ public void getSongBillListData(int type, int size, int offset, NetCallBack<SongBillListBean> callBack) { Map<String, String> params = NetHelper.getMusicApiCommonParams("baidu.ting.billboard.billList"); params.put("type", String.valueOf(type)); params.put("size", String.valueOf(size)); params.put("offset", String.valueOf(offset)); createMusicApi() .getSongBillListData(params) .enqueue(callBack); } private static NetManager instance; private NetManager() {} public static NetManager getInstance() { if (instance == null) { synchronized (NetManager.class) { if (instance == null) { instance = new NetManager(); } } } return instance; } MusicApi createMusicApi() { if (mClient == null) { OkHttpClient.Builder builder = new OkHttpClient().newBuilder(); if(BuildConfig.DEBUG){ builder.addNetworkInterceptor(new AGLogInterceptor()); } mClient = builder.build(); } if (mRetrofit == null) { mRetrofit = new Retrofit.Builder() .baseUrl(MusicApi.MUSIC_BASE_URL) .addConverterFactory(GsonConverterFactory.create()) .client(mClient) .build(); } if (mMusicApi == null) { mMusicApi = mRetrofit.create(MusicApi.class); } return mMusicApi; } }
