关键参数

主题头像下载观察者

com.autonavi.gbl.data.observer.IImageObserver

主题头像下载是异步过程，下载结果由主题头像下载观察者回调通知。

核心接口

int com.autonavi.gbl.data.ThemeService.requestDataImage(@DownLoadMode.DownLoadMode1 int downloadMode, int themeId, IImageObserver pObserver)
void com.autonavi.gbl.data.ThemeService.abortRequestDataImage(@DownLoadMode.DownLoadMode1 int downloadMode, int themeId)

说明：函数详情，请复制函数名称到在线API搜索

调用示例

调用者继承实现回调观察者

class ThemeImageObserver implements IImageObserver {\n    @Override\n    public void onDownloadImage(int themeId, @OperationErrCode.OperationErrCode1 final int opErrCode, String strFilePath, @DataType.DataType1 final DataType dataType) \n    {\n        runOnUiThread(new Runnable(){\n        \t@override\n            public void run(){\n           \t\t// 业务处理 \n            }\n        });\n    }\n}

发起请求主题头像

ThemeImageObserver themeImageObserver = new ThemeImageObserver();\n// 获取所有theme id集合\nArrayList<Integer> themeIdList = getThemeService().getThemeIdList(DOWNLOAD_MODE_NET);\n\nfor (int i=0; i<themeIdList.size(); ++i)\n{\n    // 请求下载主题头像\n    getThemeService().requestDataImage(DOWNLOAD_MODE_NET, themeIdList.get(i), themeImageObserver);\n}
