我有很多对象的json api,我想在提供密钥后将数据存储在Map中。然后我想稍后使用该地图列表。下面是我想要的方式。
Map<Integer, Integer> maplist; /// globle variable
//// inside response method inside the for loop
maplist = new HasMap<>();
maplist.put(10, 1);
//////.....
........
最佳答案
你可以做这样的事情。下面是示例代码
public void getQtyReserved() {
JsonObjectRequest request_json = new JsonObjectRequest(Request.Method.GET, cart_url + name, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
listMap = new HashMap<Integer, Integer>();
try {
JSONArray ja_data = response.getJSONArray("list");
int length = ja_data.length();
for (int i = 0; i < length; i++) {
JSONObject jsonobject = ja_data.getJSONObject(i);
int quantity_reserved = jsonobject.getInt("quantity_reserved");
int inventory_id = jsonobject.getInt("inventory_id");
listMap.put(inventory_id, quantity_reserved);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
Toast.makeText(getApplicationContext(), "its empty", Toast.LENGTH_LONG).show();
}
});
MySingleton.mySingletonInstance(getApplicationContext()).addToRequestque(request_json);
}
