我可以使用 Here Android SDK 和 Here Platform Data Extension 获取沿途的交通标志数据吗？

Question

Can I use the Here Android SDK and Here Platform Data Extension to get the traffic sign data along the route? eg Can I get all info shown in the attached image?

Answer 1

To begin using the PDE layers, create a PlatformDataRequest object:

Set<String> layers = new HashSet<String>(Arrays.asList("TRAFFIC_SIGN_FC1", "TRAFFIC_SIGN_FC2"));
Set<Long> linkIds = /*your link IDs*/
PlatformDataRequest request = PlatformDataRequest.createLinkIdsRequest(layers, linkIds);

Next, you need to supply a Listener object to get the results of the request.

  request.execute(new PlatformDataRequest.Listener<PlatformDataResult>() {
  @Override
  public void onCompleted(PlatformDataResult data, PlatformDataRequest.Error error) {
    if (error != null) {
      Log.w(TAG, "PlatformDataRequest failed with error: " + error);
    } else {
      // process received data
    }
  }
});
