任何例子都会有帮助。我想学习代码以更好地理解解析json数据。您可以在这里获得一个很好的示例： 基本上，您必须使用
JSONObjectJSONArraygetJSONObject（）getJSONArray（）getJSONString（）JSONObject json = new JSONObject(response)
JSONArray jarray = json.getJSONArray("data");
for(int i = 0; i < jarray.length(); i++){
JSONObject oneAlbum = jarray.getJSONObject(i);
//get your values
oneAlbum.getJSONString("name"); // this will return you the album's name.
}
JSONObject json=新的JSONObject（响应）
JSONArray jarray=json.getJSONArray（“数据”）；
for（int i=0；i Session.NewPermissionsRequest np = new Session.NewPermissionsRequest(this, "friends_photos");
Session.getActiveSession().requestNewReadPermissions(np);
Request rq = new Request(Session.getActiveSession(), userID + "/albums", null, HttpMethod.GET, new Request.Callback() {
@Override
public void onCompleted(Response response) {
JSONArray albumArr = response.getGraphObject().getInnerJSONObject().getJSONArray("data");
for (int i = 0; i < albumArr.length(); i++) {
JSONObject item = albumArr.getJSONObject(i);
System.out.println("id : " + item.getString("id"));
System.out.println("fromName : " + item.getJSONObject("from").getString("name"));
System.out.println("fromid : " + item.getJSONObject("from").getString("id"));
System.out.println("link : " + item.getString("link"));
System.out.println("cover_photo : " + item.getString("cover_photo"));
System.out.println("count : " + item.getString("count"));
System.out.println("created_time : " + item.getString("created_time"));
System.out.println("updated_time : " + item.getString("updated_time"));
System.out.println("can_upload : " + item.getString("can_upload"));
}
}
});
rq.executeAsync();
