时序图

获取U盘语音数据信息

关键参数

com.autonavi.gbl.data.model.OperationType

开始下载(包含下载、更新、重试动作）

com.autonavi.gbl.data.observer.IDownloadObserver

由调用者继承实现，可以添加多个，通常一个即可。下载进度，下载过程中的城市数据状态变化、以及发生错误都是通过该观察者通知回调。

核心接口

添加下载状态观察者监听

移除下载状态观察者

​

以上接口参数downLoadMode，均需传 DOWNLOAD_MODE_USB 值，表示U盘下载模式。


说明：函数详情，请复制函数名称到在线API搜索

调用示例

// 添加下载状态观察者\nDownloadObserver mDownloadObserver = new DownloadObserver();\ngetVoiceService().addUsbDownloadObserver(mDownloadObserver)\n// 移除下载状态观察者\ngetVoiceService().removeUsbDownloadObserver(mDownloadObserver);
// 获取所有voice id集合\nArrayList<Integer> voiceIdList = getVoiceService().getVoiceIdList(DOWNLOAD_MODE_USB);\n\n// 开始下载全部语音数据\ngetVoiceService().getVoice(DOWNLOAD_MODE_USB, OPERATION_TYPE_START, voiceIdList);
