Question

我正在使用ESPN Sports API。任何人都可以帮我解析这个吗？

我正在粘贴我的代码，我只能解析名称和id - 请帮助解析内部对象项目。

public class BaseballActivity extends ListActivity{

private static String url = "http://api.espn.com/v1/sports/baseball?apikey=h29yphwtf7893hktfbn7cd5g";

private static final String TAG_SPORTS = "sports";
private static final String TAG_ID = "id";
private static final String TAG_TIMESTAMP = "timestamp";
private static final String TAG_NAME = "name";
private static final String TAG_NEWS = "news";
private static final String TAG_HEADLINES = "headlines";
private static final String TAG_LINKS = "links";
private static final String TAG_API = "api";
private static final String TAG_SPORTS1 = "sports";
private static final String TAG_HREF = "href";

JSONArray sports = null;

@Override
public void onCreate(Bundle savedInstanceState) {


    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // HashMap for ListView

    ArrayList<HashMap<String, String>> sportsList = new ArrayList<HashMap<String, String>>();

    // creating Json parser instance
    JSONParser jParser = new JSONParser();

    // getting Json String from url

    JSONObject json = jParser.getJSONFromUrl(url);

    try{
        // Getting Array of Contacts
                    sports = json.getJSONArray(TAG_SPORTS);

                    // looping through All Contacts
                    for(int i = 0; i < sports.length(); i++){
                        JSONObject c = sports.getJSONObject(i);


            //String news = c.getString(TAG_NEWS);
           // String headlines = c.getString(TAG_HEADLINES);
            String name = c.getString(TAG_NAME);
           // String timestamp = c.getString(TAG_TIMESTAMP);
            String id = c.getString(TAG_ID);

         //   JSONObject links = c.getJSONObject(TAG_LINKS);
          //  JSONObject api = c.getJSONObject(TAG_API);
          //  JSONObject sports = c.getJSONObject(TAG_SPORTS1);

         //   String href = c.getString(TAG_HREF);



            HashMap<String, String> map = new HashMap<String, String>();

         //  map.put(TAG_TIMESTAMP, timestamp);
            map.put(TAG_NAME, name);
           // map.put(TAG_NEWS, news);
           // map.put(TAG_HEADLINES, headlines);
            map.put(TAG_ID, id);
         //   map.put(TAG_HREF, href);
            sportsList.add(map);
         }
    }
        catch (JSONException e) {
            e.printStackTrace();    

        }


    ListAdapter adapter = new SimpleAdapter(this, sportsList,
            R.layout.list_item,
            new String[]{TAG_NAME,TAG_ID} , new int[] {
            R.id.id,R.id.name});

   setListAdapter(adapter);   
 }
}

我建议你使用gson。对我而言，使用起来要容易得多......

编辑:(某些示例代码）

下载gson-2.2.2.jar将其添加到您的依赖项中

创建基类（当您使用多个请求时）

public abstract class RequestBase {

public String ToJson(){
    Gson gson = new Gson();
    return gson.toJson(this);
}

public abstract String getUrl();

protected String getBaseUrl(){
    return //Your URL;
}   
}

创建一个将执行您的请求的课程。

为请求和响应创建类。然后你可以用getter和setter输入它们：

公共类SomeRequest扩展RequestBase { @SerializedName（ “参数1”） private int Parameter1;

public void setParameter1(int Parameter1) {
    this.Parameter1= Parameter1;
}

public int getParameter1() {
    return Parameter1;
}

@Override
public String getUrl() {
    return this.getBaseUrl() +"YOUR/OWN/URL" + Parameter1;
}
}

和

public class SomeResponse {
@SerializedName("responseParameter1")
private int responseParameter1;

@SerializedName("responseParameter2")
private String responseParameter2;

public void setResponseParameter1(int responseParameter1) {
    this.responseParameter1= responseParameter1;
}

public int getResponseParameter1() {
    return responseParameter1;
}

public void setResponseParameter2(String responseParameter2) {
    this.responseParameter2= responseParameter2;
}

public String getResponseParameter1() {
    return responseParameter2;
}
}
