我有复杂的API，我解析并显示在列表视图中，我将努力解析JSONArray.Here我将在斗争之后Json数组这是在帖子json对象“tags_name”：[“Activities”] ，，它会来的一些对象像“tags_name”：[]， this.Kindly审查我的问题。我的API和代码如下。目前我将用模型类实现解析代码。一旦解决这个问题，我必须写列表视图编码，请帮助我。可能是我的问题形成是愚蠢的。请它看起来像意味着给框架问题一些建议。提前致谢。Android JSON解析Json数组是[]在解析时抛出空指针异常，如何以正确的方式写入？

MyAPI：

{

"status": true,

"nextpage": 0,

"count": 31,

"data": {

"postlist": [{

"posts": {},

"tags_name": ["Activities"],

"images_count": 3,

"images": [],

"post_user": [],

"is_encourage_user": true,

"encourage_feed_id": "1093"

},

{

"posts": {"id": "4647"},

"tags_name": [],

"images_count": 0,

"images": [],

"post_user": [],

"is_encourage_user": true,

"encourage_feed_id": "992"

}

]

},

"token": "wqeeqweqweqweqweqsfsdfsdf"

}

我来解析

private void parsingPostValues(String responseStatus) throws JSONException {

JSONObject responseObject = new JSONObject(responseStatus);

JSONObject datObject = responseObject.getJSONObject("data");

JSONArray postArr = new JSONArray(datObject.getString("postlist"));

for (int i = 0; i < postArr.length(); i++) {

JSONObject tempPostObject = postArr.getJSONObject(i);

JSONObject postObject = tempPostObject.getJSONObject("posts");

//setTag Array- this is the functional area i'm in bottle-neck.

try {

JSONArray tagNameArr = tempPostObject.getJSONArray("tags_name");

//ArrayList tagListdata = new ArrayList(tagNameArr.length());

if (tagNameArr.length()>0) {

for (int tagInfo = 0; tagInfo < tagNameArr.length(); tagInfo++) {

// listdata.add(tagNameArr.get(i).toString());

String tagme = "";

//Bean tagBean = new Bean();

//tagBean.setTagsArray((tagme.isEmpty() ? tagNameArr.get(tagInfo).toString() : "null")); //tagBean.setTagsArray(tagNameArr.get(tagInfo).toString());

//tagListdata.add(tagBean);

//beanAccess.setTagsArray(tagNameArr.get(tagInfo));

System.out.println("Tags Array:"+tagInfo+":"+tagNameArr.get(tagInfo));

}

//beanAccess.setTagsArray(tagListdata);

}

} catch (Exception e) {

e.printStackTrace();

}

}
