Question

目前我正在尝试使用德语的JavaScript API显示HERE地图。根据这个example，可以改变地图的语言。首次加载地图时，这适用于德语。但是，当地图视图改变时，例如到'卫星'这些设置似乎丢失了。在我在网上找到的所有多语言示例中，都禁用了更改地图视图的选项。对于所有可用的视图，语言是否可以设置为德语，或者此自定义仅限于一个视图，我需要禁用其他视图吗？

提前致谢，DG7团队

下面是完整的示例代码，以中文显示了该地图的所有视图。您可以根据需要进行更改。请使用您自己的应用ID和应用代码。以下代码中的主要代码段是createDefaultlayers，您可以在其中指定所有层的language参数。

var defaultLayers = platform.createDefaultLayers({
  tileSize: pixelRatio === 1 ? 256 : 512,
  ppi: pixelRatio === 1 ? undefined : 320,
  lg: 'CHI'
});

快乐编码！
