我的继承人的Android code
heres my android code
BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
// Instantiate a JSON object from the request response
JSONObject obj = new JSONObject(json);
List<String> items = new ArrayList<String>();
Log.i("json", "getting json");
JSONArray jArray = obj.getJSONArray("news");
for (int i=0; i < jArray.length(); i++)
{ JSONObject oneObject = jArray.getJSONObject(i);
items.add(oneObject.getString("title"));
}
setListAdapter ( new ArrayAdapter<String>(this, R.layout.single_item, items));
ListView list = getListView();
list.setTextFilterEnabled(true);
list.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), ((TextView) arg1).getText(),1000).show();
}
});
} catch(Exception e){
// In your production code handle any errors and catch the individual exceptions
e.printStackTrace();
}
}
我曾尝试在LogCat中记录它得到的结果的新闻没有价值。
I have tried logging it at LogCat gets the result no value for news.
所以我的问题是为什么呢？
so my question is why?
推荐答案
您JSON响应首先是的无效
First of your json response is invalid.
您可以测试在 JSONLint.com
二，首先你要获取数据对象作为的JSONObject ，然后你可以能够获取新闻JSONArray。
Second, first you have to fetch "data" object as a JSONObject and then you can able to fetch "news" JSONArray.
JSONObject objData = obj.getJSONObject("data");
JSONArray jArray = objData.getJSONArray("news");
