问题解析JSON阵列无钥匙 [英] Issue parsing JSON array without key
问题描述
我想使用谷歌Places API的,我基本上是试图解析JSON,而不在JSON的特定位置的关键。
I am trying to use Google Places API and I am basically trying to parse the Json without the key in a specific position in the json.
我能够解析所有的数据,并根据需要得到的值。
虽然,我有与该JSON的部件之一的问题。
I am able to parse all the data and getting the values as required. Although, I am having issues with one of the parts in that json.
这里的JSON示例:
{
"html_attributions":[],
"results":[
{
"geometry":{
"location":{
"lat":somelat,
"lng":somelng
}
},
"icon":"someicon",
"id":"someid",
"name":"somename",
"reference":"some_image_reference",
"types":[
"gas_station",
"establishment"
],
"vicinity":"Some Address"
}
],
"status":"OK"
}
现在,这里的 code段以获得从那里我有麻烦的值:
Now, here's the code snippet to get the values from where I am having trouble:
JSONObject mainJSONObject = new JSONObject(mAppUtils.loadJSON(gasURL));
JSONArray mainJSONArray = mainJSONObject.getJSONArray("results");
for(int i = 0 ; i<mainJSONArray.length();i++){
JSONObject obj = mainJSONArray.getJSONObject(i);
if(obj!=null){
String value = obj.getString("types");
Log.d("ARRAY VALUE : ", value);
}
}
在这里,code是工作完美,我能够得到的数据。
Here, the code is working perfectly and I am able to get the data.
的主要问题是结果的格式。下面是一个示例:
The main issue is the result format. Here's a sample :
06-23 22:03:51.762: D/ARRAY VALUE :(8074): ["car_repair","gas_station","establishment"]
06-23 22:03:51.782: D/ARRAY VALUE :(8074): ["convenience_store","food","store","car_repair","gas_station","establishment"]
06-23 22:03:51.782: D/ARRAY VALUE :(8074): ["gas_station","establishment"]
正如你所看到的,结果我以这种形式获得: [car_repair,gas_station,建立]
有没有更好的方法来分析上面的JSON或有什么办法,我可以代替从人物和大括号
[car_repair,gas_station,建立]
Is there a better way to parse the above json or is there any way I can replace the characters and braces from ["car_repair","gas_station","establishment"]
要就像:
car_repair,gas_station,建立,这样我可以在我的任何其他观点的TextView使用它没有显示这些括号和其他字符。
car_repair,gas_station,establishment so that I can use it in my textview of any other view without showing those braces and other characters.
编辑:
JSONObject mainJSONObject = new JSONObject(mAppUtils.loadJSON(gasURL));
JSONArray mainJSONArray = mainJSONObject.getJSONArray("results");
for(int j=0;j<mainJSONArray.length();j++)
{
JSONObject jsonObject = mainJSONArray.getJSONObject(j);
JSONArray jsonArray = jsonObject.getJSONArray("types");
for(int ju=0;ju<jsonArray.length();ju++)
{
value = jsonArray.getString(ju);
Log.d("PLACE TYPES ARRAY VALUE : ", value);
}
在此之后,这里是我得到的结果:
After this, here's the result I got :
06-23 22:53:44.928: D/PLACE TYPES ARRAY VALUE :(16322): car_repair
06-23 22:53:44.928: D/PLACE TYPES ARRAY VALUE :(16322): gas_station
06-23 22:53:44.928: D/PLACE TYPES ARRAY VALUE :(16322): establishment
06-23 22:53:44.928: D/PLACE TYPES ARRAY VALUE :(16322): convenience_store
06-23 22:53:44.938: D/PLACE TYPES ARRAY VALUE :(16322): food
06-23 22:53:44.938: D/PLACE TYPES ARRAY VALUE :(16322): store
06-23 22:53:44.938: D/PLACE TYPES ARRAY VALUE :(16322): car_repair
06-23 22:53:44.938: D/PLACE TYPES ARRAY VALUE :(16322): gas_station
06-23 22:53:44.938: D/PLACE TYPES ARRAY VALUE :(16322): establishment
06-23 22:53:44.938: D/PLACE TYPES ARRAY VALUE :(16322): gas_station
06-23 22:53:44.938: D/PLACE TYPES ARRAY VALUE :(16322): establishment
但问题是,我怎么从他们尊敬的JSON数组分隔值。
But the problem is, how do I separate the values from their respected json array.
任何帮助将是非常美联社preciated ..谢谢..:)
Any help will be really appreciated.. Thanks .. :)
推荐答案
您可以通过数组循环并获得基于该指数值
You can loop through the array and get the value based on the index
for(int i=0;i<jsonarray.length().i++)
{
String value = (String) jsonarray.get(i); // Note the cast
}
您也可以使用的getString(我)
或调用getInt(我)
取而代之的是
String value = obj.getString("types");
有无
JSONArray jsonarray = obj.getJSONArray("types");
for(int j=0;j<jsonarray.length();j++)
{
String value = jsonarray.getString(j);
}
编辑2:
有无
ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
然后在循环
HashMap<String,String> map = new HashMap<String,String>():
map.put("key",value);
list.add(map)
要获得
HashMap<String,String> map = (HashMap<String,String> ) list.get(0);// 0 is the index of item
String value =(String)map.get("key");
