mapjsonandroid
Ⅰ Android 解析json數組後用map存儲
list<map<String,String>> list = new 。。。。。();
map<String,String> map2;
然後在第二個for循環里
map2 = new HashMap<String,String>();
list.add(map2);
然後都放到map2里map.put("data",list);
取的時候要強轉
list<map<String,String>> list=(list<map<String,String>>)datalist.get(position).get("data");
Ⅱ 安卓Json --JSONArray --Map 類型轉換
1.JSONArray 轉 Map。先將JSAONArray 轉為 string類型的Json字元串，然後利用Gson將String類型的JSON字元串轉為對應的輸出類型。
2.java中json轉Map,jsonArray轉List集合,List集合轉json
Ⅲ android怎麼直接把json轉換為list
json就是些鍵值對，裡面的數據類型可能不統一，自己手動解析就可以的，主要用jsonArray和jsonObject，可以去嘗試一下http://blog.csdn.net/onlyonecoder/article/details/8490924
Ⅳ android怎麼把json轉換為hashmap
在android中把json轉換為hashmap，代碼如下：
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;
import net.sf.json.JSONArray;
import net.sf.json.JSONException;
import net.sf.json.JSONObject;
import com.wideyou.model.ExpressOrder;
import com.wideyou.warehouse.model.Storage;
public class HelperFunction {
public ExpressOrder ExpressOrderClassCast(JSONObject reserJson){
ExpressOrder expressOrder=new ExpressOrder();
expressOrder.setCid(Integer.parseInt(reserJson.getString("userId")));
expressOrder.setSendPerson(reserJson.getString("sendPerson"));
expressOrder.setSendPhone(reserJson.getString("sendPhone"));
expressOrder.setSendAddress(reserJson.getString("sendAddress"));
expressOrder.setBeginAddress(reserJson.getString("beginAddress"));
expressOrder.setOtherDes(reserJson.getString("otherDes"));
expressOrder.setEndAddress(reserJson.getString("endAddress"));
expressOrder.setReservPerson(reserJson.getString("reservPerson"));
expressOrder.setReservPhone(reserJson.getString("reservPhone"));
expressOrder.setReservAddress(reserJson.getString("reservAddress"));
expressOrder.setPostCode(reserJson.getString("reservAddress"));
expressOrder.setPayId(Integer.parseInt(reserJson.getString("payId")));
return expressOrder;
}
public Storage StorageClassCast(JSONObject reserJson){
Storage storage=new Storage();
storage.setSname(reserJson.getString("sname"));
storage.setCount(Integer.parseInt(reserJson.getString("count")));
return storage;
}
public static int getCid(JSONObject reserJson, boolean isConsumer){
if(isConsumer){
return Integer.parseInt(reserJson.getString("userId"));
}else{
return Integer.parseInt(reserJson.getString("memberId"));
}
}
//map轉換為json字元串
public static String hashMapToJson(HashMap map) {
String string = "{";
for (Iterator it = map.entrySet().iterator(); it.hasNext();) {
Entry e = (Entry) it.next();
string += "'" + e.getKey() + "':";
string += "'" + e.getValue() + "',";
}
string = string.substring(0, string.lastIndexOf(","));
string += "}";
return string;
}
public static void JsonObject2HashMap(JSONObject jo, List> rstList) {
for (Iterator keys = jo.keys(); keys.hasNext();) {
try {
String key1 = keys.next();
System.out.println("key1---" + key1 + "------" + jo.get(key1)
+ (jo.get(key1) instanceof JSONObject) + jo.get(key1)
+ (jo.get(key1) instanceof JSONArray));
if (jo.get(key1) instanceof JSONObject) {
JsonObject2HashMap((JSONObject) jo.get(key1), rstList);
continue;
}
if (jo.get(key1) instanceof JSONArray) {
JsonArray2HashMap((JSONArray) jo.get(key1), rstList);
continue;
}
System.out.println("key1:" + key1 + "----------jo.get(key1):"
+ jo.get(key1));
json2HashMap(key1, jo.get(key1), rstList);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
public static void JsonArray2HashMap(JSONArray joArr,
List> rstList) {
for (int i = 0; i < joArr.size(); i++) {
try {
if (joArr.get(i) instanceof JSONObject) {
JsonObject2HashMap((JSONObject) joArr.get(i), rstList);
continue;
}
if (joArr.get(i) instanceof JSONArray) {
JsonArray2HashMap((JSONArray) joArr.get(i), rstList);
continue;
}
System.out.println("Excepton~~~~~");
} catch (JSONException e) {
e.printStackTrace();
}
}
}
public static void json2HashMap(String key, Object value,
List> rstList) {
HashMap map = new HashMap();
map.put(key, value);
rstList.add(map);
}
}
Ⅳ android怎麼將json轉換成array map
用JSONUtil.deserialize()就可以了，範例： import org.apache.struts2.json.JSONUtil; public class JsonToJava { public static void main(String[] args) { try { String s = "{\"D\":[\"a\",\"b\"],\"A\":[\"a\",\"b\"],\"B\":[\"a\",\"b\"],\"C\":[\"a\",\"b\"]}"; Object o = JSONUtil.deserialize(s); System.out.println(o.getClass() + ": " + o); } catch (Exception e) { e.printStackTrace(System.out); } } }

Ⅶ Android百度地圖如何能通過json調用資料庫內的經緯度反應在地圖上
用資料庫的經緯度構建Point，在將Point載入到Marker，最後把Marker添加到Map上不就ok了
var p = new BMap.Point（***,***);//經緯度
var myIcon = new BMap.Icon("icon_map.png", new BMap.Size(20, 30), {});
// 創建標注對象並添加到地圖
var marker = new BMap.Marker(p, {icon: myIcon});
map.addOverlay(marker);
這是js的，你參考一下
Ⅷ android怎麼把json轉換為hashmap
用Gson這個庫吧, 簡單
String json = "";
Map<String, Object> map = new Gson().forJson(json , new TypeToken<Map<String, Object>>(){}.getType());
如果是泛型類, 要用 TypeToken 建議使用Gsonl這個庫
Ⅸ android伺服器怎麼在資料庫里添加數據
json就和map的用法一樣，new一個JSONObject json=new JSONObject();
json.put("username", username);
json.put("password",password);
用httppclient這個類傳過去，post請求的話代碼比較多就不寫了，我說下get請求比如你的web項目名字是ServletTest,並且你在項目里寫個servlet類名字叫test。那麼沒有綁定域名的情況下url地址應該是http ： // +localhost:8080/ ServletTest/test？msg= ( json.toString)。注意括弧內要在代碼實現。 然後在伺服器端收的信息就是{「username」:username , "password": password}格式的數據了。在你的test類裡面doGet(HttpRequest request , HttpResponse respone){
String msg=request.getParameter("msg");//就能得到{「username」:username , "passwor。。。。
然後JSONObject serverjson=new JSONObject(msg);
String name= serverjson.getString("username");
String password=serverjson.getString("password");
這樣就是封裝發送解析的過程
}
Ⅹ android怎麼把json轉換為hashmap
hashmap是以鍵值對(key-value)的格式保存對象的容器, 數組是按順序一個一個保存對象的容器 你把hashmap轉換成數組是想把key轉成數組呢還是把value轉成數組呢或者key和value組合成的對象轉換成數組呢.我把key和value的分別寫出來,組合對象的同理建新對象保存即可 Map<String, Object> map = new HashMap<String, Object>(); map.put("a", "tom"); map.put("b", "jerry"); Object[] keys = map.keySet().toArray(); Object[] values = map.values().toArray(); System.out.println("key數組:"+Arrays.toString(keys)); System.out.println("value數組:"+Arrays.toString(values));
