Question

我有一个真正的问题，通过Android上的新java api从功能Feed中检索地图功能。虽然我可以获得包含id和title（来自特定MapFeed）的featrureFeed，但只要我将FeatureContent添加到请求中（用于获取地标详细信息），FeatureFeed.executeGet（）将返回“400 bad request”错误。我做错了什么，或者目前实际上是否有错误？下面是我的一些代码 - 任何信息都会非常感激，因为我已经开始反对这个3天了！（我在FeatureContent类中尝试过“kml：placemark”，“atom：placemark”和“placemark”）


public class FeatureFeed { 
    @Key("atom:id") 
    public String id; 
    @Key("atom:title") 
    public String title; 
    @Key("atom:entry") 
    public List features; 

public List<FeatureEntry> maps = new ArrayList<FeatureEntry>();

public static FeatureFeed executeGet( HttpTransport transport,
                BuildMapsUrl url) throws IOException {
 url.fields = GData.getFieldsFor(FeatureFeed.class);
 AtomParser parser = new AtomParser();
 parser.namespaceDictionary = Namespace.FEED_NAMESPACE_DICTIONARY;
 transport.addParser(parser);
 HttpRequest request = transport.buildGetRequest();
 request.url = url;
 return (FeatureFeed) RedirectHandler.
                  execute(request).parseAs(FeatureFeed.class);
}


}

public class FeatureEntry implements Cloneable {
 @Key("atom:id")
 public String id;
 @Key("atom:title")
 public String title;
 @Key("atom:content")
 public FeatureContent content;

public FeatureEntry() {
  // required
 }
 public FeatureEntry(String title, FeatureContent content) {
  this.title = title;
  this.content = content;
 }
}

public class FeatureContent implements Cloneable { 

@Key("@type")
 public String contentType = "application/vnd.google-earth.kml+xml";

@Key ("kml:Placemark") // adding this always fails with Bad Request

 public FeaturePlaceMark placemark; // adding this always fails with Bad Request

public FeatureContent() {
  //required
 }

public FeatureContent(FeaturePlaceMark placemark) {
  this.placemark = placemark;
 }
}

FEED_NAMESPACE_DICTIONARY.namespaceAliasToUriMap; 
                 feedMap.put("", "http://www.w3.org/2005/Atom");
                 feedMap.put("kml", "http://www.opengis.net/kml/2.2"); 
                 feedMap.put("atom", "http://www.w3.org/2005/Atom");
                 feedMap.put("exif", "http://schemas.google.com/photos/exif/2007"); 
                 feedMap.put("gd", "http://schemas.google.com/g/2005");
                 feedMap.put("gm", "http://schemas.google.com/g/2008#mapfeature");
                 feedMap.put("geo", "http://www.w3.org/2003/01/geo/wgs84_pos#"); 
                 feedMap.put("georss", "http://www.georss.org/georss"); 
                 feedMap.put("gml", "http://www.opengis.net/gml"); 
                 feedMap.put("gphoto", "http://schemas.google.com/photos/2007"); 
                 feedMap.put("media", "http://search.yahoo.com/mrss/"); 
                 feedMap.put("openSearch", "http://a9.com/-/spec/opensearch/1.1/"); 
                 feedMap.put("xml", "http://www.w3.org/XML/1998/namespace");

我也去过那里...... 当我删除这句url.fields = GData.getFieldsFor(FeatureFeed.class);时，该程序运行良好，奇怪但有效。你可以尝试一下。
