actions设置为跳转到新建的播放页面。src/main/js/fans/pages/index/index.json"actions":{"sendRouterEvent":{"action":"router","abilityName":"com.liangzili.demos.Player","params":true}}3.判断播放页面的launch方法，从intent中提取参数params，如果播放页面是服务卡启动的，则为true。如果它是分布式上拉，则为false。params=intent.getStringParam("params");//从intent中获取跳转事件定义的params字段的值if(params.equals("true")){Intentintent0=newIntent();Operationop=newIntent.OperationBuilder().withDeviceId(DistributedUtils.getDeviceId())//参数1.是否跨设备，为空，不跨设备.withBundleName("com.liangzili.demos")//参数2.config.json中的bundleName.withAbilityName("com.liangzili.demos.Player")//参数3.跳转的能力名称.withFlags(Intent.FLAG_ABILITYSLICE_MULTI_DEVICE).build();intent0.setOperation(op);intent0.setParam("params","false");startAbility(intent0);videoSource="resources/base/media/right.mp4";}else{videoSource="resources/base/media/left.mp4";}4.申请分布式拉取-up页面权限如果params调用分布式上拉页面，必须提前获取应用的权限。提醒用户在应用首次启动时获取分布式权限。src/main/java/com/liangzili/demos/MainAbility.javarequestPermissionsFromUser(newString[]{"ohos.permission.DISTRIBUTED_DATASYNC"},0);5.要获取远程设备ID，请拉起远程设备上的页面。先获取设备的ID。publicclassDistributedUtils{publicstaticStringgetDeviceId(){//获取在线设备列表，getDeviceList获取的设备不包括本机。ListdeviceList=DeviceManager.getDeviceList(DeviceInfo.FLAG_GET_ONLINE_DEVICE);if(deviceList.isEmpty()){returnnull;}intdeviceNum=deviceList.size();ListdeviceIds=newArrayList<>(deviceNum);//提取设备IdListdeviceNames=newArrayList<>(deviceNum);//提取设备名称deviceList.forEach((device)->{deviceIds.add(device.getDeviceId());deviceNames.add(device.getDeviceName());});StringdevcieIdStr=deviceIds.get(0);returndevcieIdStr;}}6、获取播放视频的资源地址。有点晚了，请原谅我抄了一大堆。//设置沉浸式状态栏getWindow().addFlags(WindowManager.LayoutConfig.MARK_TRANSLUCENT_STATUS);initPlayer();//需要重写两个回调：VideoSurfaceCallback、VideoPlayerCallbackprivatevoidinitPlayer(){sfProvider=(SurfaceProvider)findComponentById(ResourceProvider.Id_surface);//image=(Image)findComponentById(ResourceTable.Id_img);sfProvider.getSurfaceOps().get().addCallback(newVideoSurfaceCallback());//sfProvider.pinToZTop(boolean)--如果设置为true，视频控件将显示在顶层，但是设置为false时，虽然不显示在顶层，但是出现黑屏，//需要加一行代码：WindowManager.getInstance().getTopWindow().get().setTransparent(true);sfProvider。pinToZTop(true);//WindowManager.getInstance().getTopWindow().get().setTransparent(true);player=newPlayer(getContext());//sfProvider添加监听事件sfProvider.setClickedListener(newComponent.ClickedListener(){@OverridepublicvoidonClick(Componentcomponent){if(player.isNowPlaying()){//如果正在播放，暂停player.pause();//播放按钮可见image.setVisibility(Component.VISIBLE);}else{//如果Pause，点击继续播放player.play();//播放按钮隐藏image.setVisibility(Component.HIDE);}}});}privateclassVideoSurfaceCallbackimplementsSurfaceOps.Callback{@OverridepublicvoidsurfaceCreated(SurfaceOpssurfaceOps){HiLog.info(logLabel,"surfaceCreated()called.");if(sfProvider.getSurfaceOps().isPresent()){Surfacesurface=sfProvider.getSurfaceOps().get().getSurface();playLocalFile(surface);}}@OverridepublicvoidsurfaceChanged(SurfaceOpssurfaceOps,inti,inti1,inti2){HiLog.info(logLabel,"surfaceChanged()called.");}@OverridepublicvoidsurfaceDestroyed(SurfaceOpssurfaceOps){HiLog.info(logLabel,"surfaceDestroyed()called.");}}privatevoidplayLocalFile(Surfacesurface){try{RawFileDescriptorfilDescriptor=getResourceManager().getRawFileEntry(videoSource).openRawFileDescriptor();Sourcesource=newSource(filDescriptor).getFileDescriptor(),filDescriptor.getStartPosition(),filDescriptor.getFileSize());player.setSource(source);player.setVideoSurface(surface);player.setPlayerCallback(newVideoPlayerCallback());player.prepare();sfProvider.setTop(0);player.play();}catch(Exceptione){HiLog.info(logLabel,"playUrlException:"+e.getMessage());}}参考文章：【软通动力】SurfaceProvider实现视频播放Demo-火爆的拜年视频-鸿蒙更多信息请访问：Harmonyos.51cto.com，与华为官方合作打造的鸿蒙技术社区
