Question

okHttp中onResponse中获得的json数据怎么返回

Answer 1

以下是定义在一个单例类中的方法，负责与服务器进行JSON数据交互
public JSONObject getJSONObject(String url, Map<String, String> map, final VolleyJsonCallback callback){
JSONObject params = null;
if(map != null){
params = new JSONObject(map);
}

JsonObjectRequest jObjRequest = new JsonObjectRequest(url, params,
new Response.Listener<JSONObject>() {

@Override
public void onResponse(JSONObject result) {
callback.onSuccess(result);
}
}, new Response.ErrorListener() {

@Override
public void onErrorResponse(VolleyError arg0) {
// TODO Auto-generated method stub
Log.v("error", arg0.toString());
}
});
RequestQueueSingleton.getInstance(mCtx).addToRequestQueue(jObjRequest);
return null;
}
以下是在同一个类中定义的接口
public interface VolleyJsonCallback{
void onSuccess(JSONObject result);
}
