我必须在我的应用程序中实现json数据。但我无法从服务器获取数据。我正在使用ION库。
{
"search": [{
"id": "5454003",
"description": "Larger Than Life",
"url": "http://audiojungle.net/item/larger-than-life/5454003",
"type": "item",
"sales": "1469",
"rating": "5",
"item_info": {
"id": "5454003",
"item": "Larger Than Life",
"url": "http://audiojungle.net/item/larger-than-life/5454003",
"user": "pinkzebra",
"thumbnail": "https://0.s3.envato.com/files/67162834/upbeatsongwinner2.jpg",
"sales": "1469",
"rating": "5",
"rating_decimal": "4.96",
"cost": "18.00",
"preview_type": "audio",
"preview_url": "https://0.s3.envato.com/files/94250640/preview.mp3",
"length": "2:35"
}
} ] }
这是我的json数据。我希望在我的应用程序数据中显示" cost" ,"用户"等。但我没有得到它。离子代码在这里,
Ion.with(this)
.load("http://marketplace.envato.com/api/edge/search:audiojungle,,happy.json")
.asJsonObject().setCallback(new FutureCallback<JsonObject>() {
@Override
public void onCompleted(Exception arg0, JsonObject data) {
// TODO Auto-generated method stub
}
});
所以如果有人知道那么请帮助我。提前谢谢你。

编辑:您发布的第一个信息有一些误导性信息,我检查了您发布的答案,我有适合您的工作代码,
代码:
Ion.with(this)
.load("http://marketplace.envato.com/api/edge/search:audiojungle,,happy.json")
.asString().setCallback(new FutureCallback<String>() {
@Override
public void onCompleted(Exception e, String result) {
try {
parseJson(new JSONObject(result));
} catch (JSONException e1) {
e1.printStackTrace();
}
}
});
解析响应数据:
private void parseJson(JSONObject result) {
try {
JSONArray jsonArray = result.getJSONArray("search");
for(int a=0;a<jsonArray.length();a++){
System.out.println(jsonArray.getJSONObject(a).getString("id"));
System.out.println(jsonArray.getJSONObject(a).getString("description"));
System.out.println(jsonArray.getJSONObject(a).getString("url"));
System.out.println(jsonArray.getJSONObject(a).getString("type"));
System.out.println(jsonArray.getJSONObject(a).getString("sales"));
System.out.println(jsonArray.getJSONObject(a).getString("rating"));
// JSON data with in JSONObject "item_info"
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("id"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("item"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("url"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("user"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("thumbnail"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("sales"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("rating"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("rating_decimal"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("cost"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("preview_type"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("preview_url"));
System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("length"));
}
} catch (JSONException e) {
e.printStackTrace();
}
}
答案 1 :(得分:0)
流程:
JsonArray searchArray = getJsonArray("search");
JsonObject index_0_Object= searchArray.getJsonObject("index_0");
JsonObject infoObject = index_0_Object.getJsonObject("item_info");
String id = infoObject.getString("id");
System.out.pritnln(id);
已修改:
首先:你必须找到&#34;搜索&#34;数组之后,它使用索引来获取它的对象,所以现在你有了JsonObject,从它得到&#34; item_info&#34;对象,从那里你可以找到&#34; id&#34;对象。

> yes i got it...
Ion.with(this)
.load("http://marketplace.envato.com/api/edge/search:audiojungle,,happy.json")
.asString().setCallback(new FutureCallback<String>() {
@Override
public void onCompleted(Exception arg0, String data) {
// TODO Auto-generated method stub
try {
JSONObject jObject = new JSONObject(data);
JSONArray jArray = jObject.getJSONArray("search");
for ( int i = 0 ; i < jArray.size() ; i++ )
{
JSONObject jObject_0 = jArray.getJSONObject(i);
JSONObject jObj = jObject_0.getJSONObject("id");
Log.e("id : ",id+"");
}
//JSONObject jObject_0 = jArray.getJSONObject(1);
//JSONObject jObj = jObject_0.getJSONObject("item_info");
//cost.setText(jObj.getString("cost"));
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
> but this returns only one value. i want to multiple value according to array list.
