依赖的导入：compile 'io.reactivex.rxjava2:rxjava:2.1.1'compile 'io.reactivex.rxjava2:rxandroid:2.0.1'//retrofitcompile 'com.squareup.retrofit2:retrofit:2.2.0'//Gson convertercompile 'com.squareup.retrofit2:converter-gson:2.2.0'//RxJava2 Adaptercompile 'com.squareup.retrofit2:adapter-rxjava2:2.2.0'//okhttpcompile 'com.squareup.okhttp3:okhttp:3.6.0'implementation 'com.android.support:recyclerview-v7:26.1.0'compile 'com.youth.banner:banner:1.4.9'compile 'com.github.bumptech.glide:glide:3.7.0'compile 'com.facebook.fresco:fresco:0.11.0'compile(name: 'ijkplayer-java-release', ext: 'aar')compile 'org.greenrobot:greendao:3.2.0'
第一步：注解@Streaming/*大文件需要加入这个判断，防止下载过程中写入到内存中*/@GET
//我们在下载文件的时候，需要传回range值来继续下载
Observable<ResponseBody> download(@Header("RANGE") String start, @Url String url);第二步：封装Retrofitpublic class BaseService {//okhttp的简单实例，如果我们加拦截器的话，就配上用场了 private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();//实例retrofit private static Retrofit.Builder builder = new Retrofit.Builder() .baseUrl("http://result.eolinker.com/") .addConverterFactory(GsonConverterFactory.create()) .addCallAdapterFactory(RxJava2CallAdapterFactory.create());//创建一个方法，提供外部创建retrofit public static <S> S createService(Class<S> serviceClass) { Retrofit retrofit = builder.client(httpClient.build()).build(); return retrofit.create(serviceClass); }}第5步：视频播放：第三步：model层处理下载问题//这个方法使我们实现model接口中的那个方法String url3=""; @Override public void getData(String start, String url, final String url2, final GetCallback callback) { this.url3 = url;//调用我们自己创建的retrofit中的方法 BaseService.createService(GetInterface.class).download(start, url3) .subscribeOn(Schedulers.io()) //可以不写在主线程， .observeOn(AndroidSchedulers.mainThread()) .subscribe(new Observer<ResponseBody>() { @Override public void onSubscribe(Disposable d) { } @Override public void onNext(ResponseBody responseBody) { //获取文件的总长度 final long l = responseBody.contentLength(); Log.i("=====length=====", "onNext: " + l); //调用文件的长度 downloadfile(l, url2); } @Override public void onError(Throwable e) { } @Override public void onComplete() { } }); }//传来的参数是我们文件的总长度和我们文件下载的路径 public void downloadfile(long length, String url2) { final File file = new File(url2); if (!file.exists()) { try { file.createNewFile(); } catch (IOException e) { e.printStackTrace(); } }第4步：int threadNum = 5; long blockSize = length / threadNum; long startPosition = 0; long end = 0;// //四舍五入--- 让一个数字+0。5在四舍五入 就变成 向上取整 //计算出下载块以后 创建线程执行下载操作 for (int i = 0; i < threadNum; i++) { //在下载之前，我们先判断一下数据库有没有值，因为断点续传我们暂停后会有数据保存到数据库 List<Bean2> cityInfoList = DBHelper.getInstance(context).getCityInfoList(i);//如果有的话，我们将数据库中的数据查询出来，然后对我们下载的开始值和结束值进行赋值 if (cityInfoList.size() > 0) { Long range = cityInfoList.get(0).getRange(); Long end1 = cityInfoList.get(0).getEnd(); startPosition = range; end = end1; Log.i("=====", "downloadFile: " + startPosition + "==" + end); } else {//如果没有值的话我们要计算它的长度，然后给开始结束的位置进行赋值 startPosition = blockSize * i; //让最后一个线程下载的大小是正好的， 总长度 - 除了最后一个块的大小和 if (i == threadNum - 1) { blockSize = length - blockSize * (threadNum - 1); } //然后将我们计算好的中存放到数据库 end = startPosition + blockSize - 1; Bean2 bean2 = new Bean2(); bean2.setThreadNum(i + ""); bean2.setRange(startPosition); bean2.setEnd(end);//数据库方法，插入的 DBHelper.getInstance(context).addToCityInfoTable(bean2); } //开启下载的任务 downloadTask(startPosition, file, end, length, i); }} }downloadTask方法：public void downloadTask(final long startPosition, final File file, long end, final long length, final int i) { //计算开始位置 String range = "bytes=" + startPosition + "-" + end; BaseService.createService(GetInterface.class).download(range, url3) .subscribeOn(Schedulers.io()) .observeOn(Schedulers.io()) .subscribe(new Observer<ResponseBody>() { @Override public void onSubscribe(Disposable d) { } @Override public void onNext(ResponseBody responseBody) { ///文件的 输入流 BufferedInputStream bis = null;//写入文件的地址 RandomAccessFile raf = null; try { bis = new BufferedInputStream(responseBody.byteStream()); raf = new RandomAccessFile(file, "rwd"); raf.seek(startPosition); byte[] buff = new byte[1024 * 8]; int len = 0; long length2 = 0; List<Bean2> cityInfoList = DBHelper.getInstance(context).getCityInfoList(i); if (cityInfoList.size() > 0) { length2 = cityInfoList.get(0).getRange(); Log.i("=====继续length2=======", "onNext: " + length2); } while ((len = bis.read(buff)) != -1) { Log.i("===循环继续====", "onNext: ");//正在下载的判断 if (stateDownload == DOWNLOAD_ING) { Log.i("===继续下载====", "onNext: "); length2 += len; raf.write(buff, 0, len); handler.sendEmptyMessage((int) length2);//当我们点击暂停的时候，我们要改变状态。当我们点击继续的时候，我们一定要记得把状态值改变回下载的状态，（本人就是犯了这么个地级错误） } else if (stateDownload == DOWNLOAD_PAUSE) { //更新数据库 DBHelper.getInstance(context).updateInfo(i, length2); break; } } } catch (IOException e) { e.printStackTrace(); } finally { if (bis != null) { try { bis.close(); } catch (IOException e) { e.printStackTrace(); } } if (raf != null) { try { raf.close(); } catch (IOException e) { e.printStackTrace(); } } } } @Override public void onError(Throwable e) { } @Override public void onComplete() { } });第5步：接口改变状态值：//暂停@Overridepublic void stop() { stateDownload = DOWNLOAD_PAUSE;}//继续@Overridepublic void jixu() { stateDownload = DOWNLOAD_ING;}@Overridepublic void getProgress() {}//集成GreenDaopublic class DBHelper { private static Context mContext;
