在android中解析和存储嵌套的JSON数据

我必须解析和存储facebook页面的jSON数据。我的jSON数据是。 我使用getter setter在Arraylist中存储数据。 Getter Setter类

public class FBStatus {
    private String postId, category, name, catId, story, picture, type,
            status_type, objectId, createdTime, updatedTime, shareCount;

    public String getCategory() {

使用这段代码，我能够将父元素数据存储在arraylist中，但在这方面我遇到了一个难题，即如何存储嵌套元素的数据，如喜欢和注释。

请建议我如何解决这个问题。非常感谢您的宝贵建议。谢谢

我解决了这个问题，我不得不根据facebook提供的JSON设计嵌套的getter和setter。在getter setter类中添加了两个

ArrayList

  public List<Likes> likesData = new ArrayList<FBStatus.Likes>();
    public List<Comment> commentData = new ArrayList<FBStatus.Comment>();

公共列表likesData=newarraylist（）；
public List commentData=new ArrayList（）；

解析类中所做的一些更改

    private ArrayList<FBStatus> mData = new ArrayList<FBStatus>();

        jObj = parsing.getJSONFromUrl(FB_COMMENT + mAccessToken);
        try {
            data = jObj.getJSONArray(TAG_DATA);
            for (int i = 0; i < data.length(); i++) {
                FBStatus bean = new FBStatus();
                JSONObject c = data.getJSONObject(i);
                bean.setPostId(c.getString(TAG_ID));
                JSONObject fromElement = new JSONObject(data.getJSONObject(i)
                        .getString(TAG_FROM));
                if (fromElement != null) {
                    bean.setCategory(fromElement.getString(TAG_CATEGORY));
                    bean.setCatId(fromElement.getString(TAG_ID));
